1. Agreement
These Terms of Use (“Terms”) govern your access to and use of Vesperline and form a legally binding agreement between you and Mehdi YILDIRIM, the developer and publisher of Vesperline (“Developer,” “we,” “us,” or “our”).
Vesperline is made available under the Logosmind storefront and brand. Logosmind is a commercial name and storefront used by the Developer and is not a separate legal entity.
By downloading, installing, accessing, or using Vesperline, you agree to be bound by these Terms, the Developer’s Privacy Policy, and any applicable terms and conditions of the platform through which you download or access the game, including the applicable terms of the Apple App Store or Google Play Store.
If you do not agree to these Terms, you must not download, install, access, or use Vesperline.
If you are a consumer, nothing in these Terms limits or excludes any mandatory rights or protections that cannot lawfully be waived under applicable law.
These Terms are originally prepared in English. Translations may be provided for convenience. To the extent permitted by applicable law, if there is any inconsistency between the English version and a translated version, the English version will prevail.
The first public release is being prepared with a free opening act, an optional Full Game unlock and an optional Support the Developer purchase. There are no advertisements in this release. Purchase availability depends on the installed build and your App Store storefront; a product is offered for sale only when Apple returns its details and price. TestFlight purchases use Apple’s sandbox.
2. Eligibility and Younger Users
Vesperline is intended for a general audience and is not intended for children under the age of 13.
You must be at least 13 years old to download, access, or use Vesperline. By downloading, accessing, or using the game, you represent and warrant that you are at least 13 years old.
If you are under the age of legal majority in the country or region where you live, you may use Vesperline only with the permission and supervision of a parent or legal guardian.
For users in Japan, the age of legal majority is 18. Users between the ages of 13 and 17 may use Vesperline only with the permission and supervision of a parent or legal guardian.
Parents and legal guardians are responsible for supervising a minor’s use of Vesperline, including purchases, advertising interactions, privacy choices, and applicable device, Apple App Store, or Google Play parental controls.
Vesperline does not knowingly permit users under 13 to use the game or knowingly collect personal information from children under 13 in a manner prohibited by applicable law.
Where applicable law requires parental or legal-guardian consent for the processing of a minor’s personal information, such consent will be obtained or the relevant processing will be restricted as required by law.
We do not knowingly serve personalized or interest-based advertising to minors where such advertising is prohibited by applicable law, platform rules, or advertising-service requirements.
If we become aware that a user is below the minimum permitted age or is using Vesperline without any legally required parental or guardian permission, we may restrict or terminate access and take reasonable steps regarding associated personal information as required by applicable law.
3. Personal License
Subject to your compliance with these Terms and the applicable terms of the platform through which you obtain Vesperline, the Developer grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, and revocable license to download, install, access, and use Vesperline solely for your personal, non-commercial entertainment on devices that you own or control.
This license does not transfer to you any ownership right or other proprietary interest in Vesperline or any part of the game.
Except where applicable law expressly permits otherwise, you may not copy, reproduce, distribute, sell, rent, lease, sublicense, publicly display, publicly perform, modify, adapt, translate, create derivative works from, commercially exploit, or otherwise use Vesperline or any part of it outside the scope of the license granted by these Terms.
You may not remove, obscure, or alter any copyright, trademark, attribution, proprietary, or other legal notices appearing in or with Vesperline.
The license granted under this Section automatically terminates if you materially breach these Terms, subject to any rights or protections that cannot lawfully be excluded.
4. Game Content, Virtual Items and Game Economy
Vesperline is a portrait pinball roguelite. The opening act—three rounds including its boss—is free to replay. Full Game unlocks the remaining eleven acts of the 36-round campaign. A purchase does not guarantee success or remove the game’s difficulty.
Each new run starts with zero gold. Gold, permanent powers, single-use items and summoned helpers are earned or obtained through gameplay. Powers are permanent only for that run; they are not permanent purchases for your account. A run’s health, build and item charges follow the in-game rules. Failure ends the run.
The Night Market uses earned in-game gold, not real money. Gold cannot be bought, sold, transferred outside the game or redeemed for cash. The doorman’s stage-retry toll is also paid only with earned gold.
Virtual items are licensed only for use within Vesperline. They do not grant ownership of game content and have no real-world cash value. Vesperline does not sell gold, extra lives, paid random items or combat advantages.
The Developer may reasonably adjust enemy behaviour, layouts, rewards, item costs and balancing for development, security, fair operation or legal compliance. Corrections to items obtained through bugs, fraud or unintended behaviour remain subject to mandatory consumer rights and platform rules.
5. Purchases and Payments
Full Game is an optional, one-time, non-consumable purchase that unlocks the remaining acts. It can be restored using Restore Purchases with the Apple Account or Google Play account used to buy it, in the same store. Ownership is not transferred between Apple and Google Play. Replaying a run does not require buying it again. The unlock does not restore a deleted local run.
Full Game also includes an ad-free game if advertising is added later. Our Cloudflare ownership service records verified purchase history and separate rights. Any future Founder programme will state its eligibility and benefits separately; buying developer support does not grant Full Game, ad-free access or Founder status.
Support the Developer is an optional, repeatable consumable purchase. It supports development but grants no gold, powers, extra lives or Full Game access. Each support purchase requires a separate confirmation. It is not a subscription and is not restorable as an entitlement. Mandatory purchase and refund rights remain unaffected.
On supported iOS builds, purchases use Apple’s In-App Purchase system; supported Android builds use Google Play Billing. Availability depends on the build and purchase-service activation. The initial Android internal test does not offer purchases. The relevant store supplies localized prices and availability. Review the item, price and currency in the store’s confirmation sheet before buying. No price or availability is promised by this website.
The Developer does not collect or store full payment-card details. TestFlight transactions use Apple’s sandbox and do not charge real money. On Android, only Google-designated test payment methods are test transactions; participation in a test track alone does not make purchases free. A pending or declined purchase does not unlock paid content; cancelling a purchase leaves the free act and existing local progress available.
Restore Purchases checks eligible non-consumable entitlements with the relevant store and our ownership verification service. A refunded or revoked Full Game transaction may remove access to paid acts; free content remains available. A failed network request does not by itself erase a previously saved entitlement.
Refunds, billing disputes, unauthorized transactions and payment reversals are handled under the relevant store’s procedures and applicable law. For Google Play purchases, use Google Play order history or purchase support (https://support.google.com/googleplay/answer/2479637). See Apple’s purchase support. Nothing here excludes mandatory consumer remedies.
Minors need the permission and supervision required by Section 2. Parents and guardians should use device and Apple App Store or Google Play purchase controls. Vesperline does not offer subscriptions. Any future subscription would require separate, clear billing and cancellation disclosures before purchase.
6. Advertising
The first release has no advertisements. There are no rewarded videos, banners, interstitials, app-open advertisements, advertising SDKs or ad-based progression requirements. Neither a purchase nor an advertising-consent choice is required to play the free act.
Advertising may be considered for a later release. No provider, placement or format is announced here. Before enabling advertising, the Developer will update these Terms, the Privacy Policy, applicable store disclosures and in-game notices, and implement any legally required consent, permission or privacy choices. These Terms do not themselves give consent to future tracking. Changes remain subject to rights attached to completed purchases.
7. Chance-Based Features and Rewards
Run seeds vary encounters, routes, board arrangements and Night Market stock. Rerolling stock spends earned in-game gold. These gameplay systems do not award real money or transferable prizes, and there are no paid loot boxes or paid randomized rewards.
A particular item, encounter or result is not guaranteed. The Developer may adjust random selection and balance for fair operation, maintenance or legal compliance. Virtual rewards remain subject to Section 4.
8. Local Save and Game Progress
Vesperline saves the current run locally, including stage, enemies, health, earned gold, powers, remaining item charges and route choices. Continuing safely re-serves the ball; it does not resume the exact mid-flight position.
Leaving with critically low health can trigger the doorman’s retry rules: pay the displayed in-game gold toll to replay that stage, if eligible, or start a new run. Closing the app is not a way to reset damage or obtain a free revival. At the free-content boundary, the current run is retained so an eligible Full Game owner can continue.
The game has no required account or developer-operated cloud save. Deleting the game or local data, losing a device, corruption or changing devices may permanently remove run progress. We cannot guarantee recovery of deleted local data. Operating-system backups are controlled separately by you and your platform.
In supported Android builds, a developer-provided review code may grant review access for the current app session after online verification. This is separate from a Full Game purchase and is not a store receipt, transferable purchase or restorable ownership. Reviewers may reuse a valid code after restarting. This review feature is not available in iOS builds.
Purchase entitlements and local transaction records are separate from run progress. Apple maintains its own transaction records; Restore Purchases can restore eligible Full Game access but does not restore a deleted run or consumed Support the Developer purchases. Mandatory rights remain unaffected.
9. Acceptable Use and Prohibited Conduct
You may use Vesperline only for lawful, personal, and non-commercial purposes and in accordance with these Terms.
You may not:
- use Vesperline in violation of applicable law or the rights of any person or third party;
- copy, distribute, modify, sell, or exploit Vesperline except as expressly permitted by these Terms;
- use cheats, bots, scripts, automation, exploits, modified clients, unauthorized software, or similar methods to manipulate gameplay, rewards, scores, virtual currency, advertising, purchases, or other game systems;
- circumvent security, purchase controls, parental controls, advertising systems, access restrictions, or technical protections;
- attempt unauthorized access to the game, software, systems, services, servers, or related infrastructure;
- interfere with, disrupt, damage, overload, or impair Vesperline, Logosmind, the Apple App Store, Google Play Store, advertising services, or related services;
- distribute modified, cracked, pirated, or unauthorized copies of Vesperline;
- reverse engineer, decompile, disassemble, decode, or attempt to derive source code, algorithms, underlying structure, or non-public technical information except where applicable law expressly permits such activity;
- exploit bugs, errors, vulnerabilities, preview systems, reward systems, or unintended behavior to unfairly obtain benefits or materially disrupt the game;
- scrape, harvest, or systematically extract Vesperline content or data;
- use Vesperline, its artwork, characters, code, audio, game content, or other materials to develop, train, fine-tune, enhance, evaluate, or provide source material for any artificial intelligence, machine-learning, or generative-AI system without the Developer’s prior written permission, except where such restriction is prohibited by applicable law; or
- use Vesperline or its content for unauthorized commercial exploitation or the development of competing products or services.
The Developer may take reasonable measures to investigate, prevent, restrict, or respond to suspected violations of this Section, including restricting access to affected features or terminating the license granted under these Terms where appropriate.
Nothing in this Section restricts activities that applicable law expressly permits and that cannot lawfully be prohibited by contract.
10. Ownership and Intellectual Property
Vesperline, including its software, source and object code, game design, gameplay systems, levels, characters, artwork, animations, graphics, user interface, text, sounds, music, visual elements, logos, names, branding, and other original content, is owned by the Developer or used by the Developer under applicable licenses.
The Vesperline name, Logosmind name, associated logos, branding, and other identifiers may be protected by trademark, copyright, unfair competition, or other intellectual property laws.
Except for the limited license expressly granted under these Terms, no right, title, license, or ownership interest in Vesperline or any related intellectual property is transferred to you.
You may not use, reproduce, distribute, modify, publish, commercially exploit, or create derivative works from Vesperline content except as expressly permitted by these Terms or by applicable law.
Third-party software, libraries, services, fonts, music, artwork, platform materials, advertising content, and other third-party components remain subject to the rights and license terms of their respective owners.
Nothing in these Terms grants you any right to commercially use the Developer’s or Logosmind’s trademarks, trade names, logos, branding, or other identifiers without prior written permission.
11. Availability, Updates, Regional Access and Connectivity
Vesperline may be updated, modified, expanded, restricted, suspended, or discontinued from time to time.
The Developer may reasonably change or remove features, levels, rewards, game modes, virtual items, balancing, interfaces, technical requirements, or other aspects of the game where necessary for development, maintenance, security, legal compliance, platform requirements, fair operation, or improvement of the player experience.
Updates may be required to continue using some or all features of Vesperline. The Developer does not guarantee compatibility with every device, operating-system version, or platform configuration.
The availability of Vesperline, virtual items, advertisements, purchases, rewards, or particular features may vary by country or region due to legal requirements, platform availability, third-party-service availability, technical limitations, or other legitimate operational reasons.
If you change your country or region, certain features, virtual items, purchases, advertisements, or content previously available to you may no longer be available where permitted or required by applicable law.
Core gameplay is offline. Downloads, updates, product information, purchases, restoration, purchase-history synchronization and opening web or support links require connectivity. You are responsible for maintaining your own internet connection and for any data, mobile-carrier, internet-service-provider, or other third-party charges associated with your use of the game.
The availability of the game may also depend on third-party platforms, advertising providers, network connectivity, device capabilities, or circumstances outside the Developer’s reasonable control.
Where reasonably necessary, the Developer may temporarily suspend access to the game or particular features for maintenance, security, technical, legal, or platform-related reasons.
If Vesperline or a material paid feature is permanently discontinued, the Developer will take any steps required by applicable law and applicable platform rules regarding affected paid transactions or virtual items.
Nothing in this Section limits mandatory consumer rights that cannot lawfully be excluded.
12. Suspension and Termination
The Developer may suspend, restrict, or terminate your access to Vesperline or particular features if you materially violate these Terms, misuse the game, engage in fraud or abuse, manipulate game systems, create a security or legal risk, or if suspension, restriction, or termination is reasonably required by applicable law, a competent authority, the Apple App Store, Google Play Store, or another applicable platform provider.
The Developer may also suspend, restrict, or terminate access where your use of Vesperline may harm the Developer, other users, platform providers, advertising partners, or related services.
Where reasonably practicable and appropriate, the Developer may take less restrictive measures before terminating access.
Upon termination of your license, you must stop using Vesperline and the rights granted under these Terms will end, except for provisions intended by their nature to survive termination.
Termination or suspension does not eliminate rights or obligations that arose before termination.
Paid virtual items, completed purchases, and mandatory consumer rights remain subject to applicable law and the applicable Apple App Store or Google Play Store rules.
Nothing in this Section permits the Developer to restrict or terminate access in a manner prohibited by applicable law.
13. Disclaimers
To the fullest extent permitted by applicable law, Vesperline is provided on an “as is” and “as available” basis.
The Developer does not guarantee that Vesperline will always be available, uninterrupted, error-free, secure, compatible with every device or operating-system version, or free from bugs, defects, delays, data loss, or other technical issues.
The Developer does not guarantee that any particular feature, level, reward, virtual item, advertisement, game mode, third-party service, or other functionality will always be available or operate in the same manner.
Vesperline may rely on third-party platforms, advertising providers, software development kits, networks, stores, and other services not fully controlled by the Developer. To the extent permitted by applicable law, the Developer does not warrant the continuous availability, accuracy, security, or performance of those third-party services.
The Developer does not guarantee any particular score, reward, virtual item, achievement, ranking, or gameplay outcome.
Nothing in these Terms excludes or limits any warranty, consumer protection, or other right that cannot lawfully be excluded or limited.
14. Limitation of Liability
To the fullest extent permitted by applicable law, the Developer will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, business opportunity, goodwill, data, game progress, virtual items, or other intangible losses arising out of or relating to your use of, or inability to use, Vesperline.
To the fullest extent permitted by applicable law, the Developer will not be responsible for losses caused by circumstances outside the Developer’s reasonable control, including failures or interruptions involving the Apple App Store, Google Play Store, advertising providers, network services, device hardware, operating systems, or other third-party platforms or services.
Where the Developer is found legally liable to you despite the limitations above, the Developer’s total aggregate liability arising out of or relating to Vesperline will, to the fullest extent permitted by applicable law, not exceed the greater of:
(a) the total amount you paid for Vesperline or in-game purchases during the twelve months immediately preceding the event giving rise to the claim; or
(b) USD 100.
The limitations in this Section do not apply to liability that cannot lawfully be excluded or limited, including liability arising from fraud, willful misconduct, or any other liability that applicable law requires to remain unrestricted.
Nothing in this Section limits mandatory consumer rights or remedies available under applicable law.
15. Privacy and Third-Party Services
Core gameplay and run saves operate locally. The game has no advertising SDK or account sign-up. Participating 1.0.4 TestFlight builds offer optional GameAnalytics, OFF by default and separately explained in the Privacy Policy. Declining analytics does not affect gameplay or purchases. Apple handles payments. Our Cloudflare service verifies and records signed Apple transactions to maintain purchase history and entitlements. Opening website or support links uses external services.
The Privacy Policy describes local information, purchase records, platform diagnostics, website infrastructure, support correspondence and available rights. It is a disclosure of data practices, not a request for advertising consent. Third-party services operate under their own applicable terms and policies.
16. Apple and Google Platform Terms
If you download or access Vesperline through the Apple App Store or Google Play Store, your use of the game is also subject to the applicable terms, rules, and policies of that platform.
The Developer, and not Apple or Google, is responsible for Vesperline and for providing any support or maintenance required by applicable law, except to the extent that the relevant platform expressly assumes responsibility under its own terms.
Apple and Google are not responsible for investigating, defending, settling, or discharging claims relating to Vesperline, except where applicable platform terms or law provide otherwise.
If Vesperline fails to conform to an applicable warranty that cannot lawfully be excluded, you may have rights or remedies under applicable law or the relevant platform’s procedures.
Any refund or other remedy provided by Apple or Google is subject to that platform’s applicable rules and procedures.
You must comply with applicable third-party terms governing your device, network connection, Apple App Store account, or Google Play account.
For copies of Vesperline obtained through the Apple App Store, Apple and its subsidiaries are intended third-party beneficiaries of these Terms to the extent required by Apple’s applicable terms and may enforce the relevant provisions of these Terms against you.
Nothing in this Section limits any mandatory rights or remedies available under applicable law.
For current App Store copies, Apple’s Standard Licensed Application End User License Agreement also applies. These publisher Terms supplement the applicable platform licence; they do not announce a custom App Store EULA.
17. Governing Law and Disputes
These Terms and any dispute, claim, or controversy arising out of or relating to Vesperline or these Terms are governed by and construed in accordance with the laws of the Republic of Türkiye, without regard to conflict-of-law principles.
If you are a consumer, this choice of Turkish law does not deprive you of any mandatory consumer protection rights that apply to you under the laws of your country or region of residence and that cannot lawfully be waived by contract.
To the extent permitted by applicable law, the competent courts of Istanbul, Türkiye shall have jurisdiction over disputes arising from or relating to these Terms or Vesperline.
Nothing in these Terms prevents a consumer from bringing a claim before another court, regulatory authority, consumer protection body, or competent authority where applicable mandatory law gives the consumer a non-waivable right to do so.
Before commencing formal proceedings, the parties are encouraged to attempt to resolve the matter informally by contacting the Developer using the contact information provided in these Terms.
Nothing in this Section prevents either party from seeking urgent or interim relief where reasonably necessary to protect intellectual property, security, or other rights requiring immediate protection.
18. Changes to These Terms
The Developer may update these Terms from time to time to reflect changes to Vesperline, applicable law, platform requirements, business practices, security needs, or other reasonable operational reasons.
When these Terms are updated, the revised version will display an updated “Effective” or “Last Updated” date.
Where applicable law or platform requirements require additional notice or consent for a material change, the Developer will provide such notice or obtain such consent as required.
Changes will apply prospectively from their effective date unless applicable law permits or requires otherwise.
Your continued use of Vesperline after updated Terms become effective constitutes acceptance of the updated Terms to the extent permitted by applicable law.
If you do not agree to the updated Terms, you should stop using Vesperline.
Nothing in this Section permits the Developer to retroactively remove or materially reduce rights relating to completed paid transactions where such action is prohibited by applicable law.
19. General Terms
These Terms, together with the Privacy Policy and any additional terms expressly presented in connection with a particular feature, purchase, promotion, or service, constitute the agreement between you and the Developer regarding your use of Vesperline.
If any provision of these Terms is found to be invalid, unlawful, or unenforceable, that provision will be interpreted or limited to the minimum extent necessary to make it enforceable where permitted by law, and the remaining provisions will continue in full force and effect.
The Developer’s failure or delay in enforcing any provision of these Terms does not constitute a waiver of that provision or of the right to enforce it later.
You may not assign or transfer your rights or obligations under these Terms without the Developer’s prior written consent.
The Developer may assign or transfer these Terms, in whole or in part, in connection with a sale, transfer, reorganization, incorporation, or other change involving Vesperline or the Developer’s business, subject to applicable law and without reducing mandatory consumer rights.
Section headings are provided for convenience only and do not affect the interpretation of these Terms.
Any provisions that by their nature should continue after termination, including provisions concerning intellectual property, limitations of liability, indemnification, accrued rights and obligations, and dispute-related provisions, will survive termination.
20. User Responsibility and Indemnification
To the fullest extent permitted by applicable law, you are responsible for your use of Vesperline and for violations of these Terms resulting from your own acts or omissions.
You agree to indemnify and hold harmless the Developer from direct losses, liabilities, damages, and reasonable costs arising from a third-party claim resulting from:
(a) your material breach of these Terms;
(b) your unlawful or fraudulent use of Vesperline;
(c) your infringement or violation of a third party’s intellectual-property or other legal rights; or
(d) your intentional misuse of Vesperline or its systems.
You are not required to indemnify the Developer for losses resulting from the Developer’s own fraud, willful misconduct, negligence to the extent liability for such negligence cannot lawfully be shifted to you, or matters for which you are not legally responsible.
The Developer will take reasonable steps to mitigate losses for which indemnification is sought.
21. Health and Safety Warning
A small number of people may experience dizziness, altered vision, eye or muscle twitching, loss of awareness, disorientation, involuntary movement, seizures, motion discomfort, or similar symptoms when exposed to certain visual patterns, flashing effects, animations, or video-game content.
If you experience any such symptoms while using Vesperline, stop playing and seek appropriate medical advice before resuming use.
If you know that you have a condition that may be affected by flashing lights, visual patterns, or video games, consider seeking medical advice before playing.
The game includes CRT distortion, scanlines, light effects, motion and haptics. Settings provides Clean Display, Reduce Motion and a separate haptic toggle. These controls reduce certain effects; they do not guarantee elimination of all triggering content. Players should take appropriate breaks during extended play.
22. Export, Sanctions and Legal Restrictions
You may not download, access, use, export, re-export, transfer, or otherwise make Vesperline available in violation of applicable export-control, sanctions, trade-restriction, or other applicable laws.
You may not use Vesperline if applicable law prohibits the Developer from providing the game or related services to you.
The availability of Vesperline, purchases, virtual items, advertising, or particular features may therefore be restricted in certain countries, territories, or circumstances.
The Developer may restrict access or transactions where reasonably necessary to comply with applicable legal obligations, sanctions requirements, platform restrictions, or binding governmental orders.
23. Information for Users in Japan
Users located in Japan may be provided with additional disclosures, notices, or information required under applicable Japanese law.
Such disclosures may be made available through Vesperline, the applicable app-store listing, the Developer’s website, purchase interfaces, or a separate disclosure page and will apply to users in Japan where required by law.
Nothing in this Section limits any mandatory rights available to users in Japan under applicable Japanese law.
24. Contact and Developer Information
