1. OUR SERVICES

Proof of Focus is a focus and study accountability app. It helps users run focus timers, create and join accountability rooms, stay accountable with friends, track focus progress, earn in-app rewards, receive notifications, manage focus penalties, and optionally subscribe to Pro features.

The Services are productivity and accountability tools only. They do not guarantee improved productivity, academic results, health outcomes, employment outcomes, or any specific personal result.

2. ELIGIBILITY

Proof of Focus is not directed to children under 13. You may not use the Services if you are under 13. If you are under the age of majority where you live, you may use the Services only with permission from a parent or legal guardian.

By using the Services, you represent that you are allowed to enter into these Terms and that your use of the Services is lawful in your location.

3. ACCOUNTS

The Services may support guest access, email/password authentication, Google Sign-In, and Apple Sign-In. You are responsible for the activity that occurs under your account and for keeping your sign-in method secure.

Guest access may rely on app or device state. Guest progress may be lost if you delete the app, clear app data, change devices, lose access to the device, or if local or anonymous authentication state is removed. Linking an account can improve account recovery.

You agree to provide accurate account and profile information and to keep it updated where needed.

4. ACCEPTABLE USE

You agree not to:

We may investigate suspected violations and may restrict, suspend, or terminate access where needed to protect users, comply with law, enforce these Terms, or maintain service integrity.

You may report abusive display names, avatars, room names, harassment, impersonation, spam, or other misuse through https://focus.ertdev.space/support/. You may also use available in-app blocking controls. We may review reports and remove content, restrict accounts, or take other action needed to protect users and the Services.

5. FOCUS ROOMS, RULES, REWARDS, AND PENALTIES

Proof of Focus uses device, app, room, and session signals to operate focus features. Depending on the room mode and settings, moving the device, leaving the app, lowering volume, failing to stay present, or other rule events may be recorded as violations.

Rewards, XP, coins, streaks, levels, focus debt, penalty minutes, and room-visible violation events are in-app motivational features. They have no cash value, are not financial instruments, and may be changed, recalculated, limited, reset, or removed where needed to fix errors, prevent abuse, or update the product.

In room modes where accountability is enabled, some activity may be visible to other participants, such as display name, avatar, room participation, readiness, focus status, violation events, and penalty minutes. Use rooms respectfully.

The app's detection systems are not perfect. Device permissions, sensors, operating system behavior, network conditions, battery settings, and service availability can affect focus detection and notifications.

6. SUBSCRIPTIONS AND PURCHASES

Proof of Focus may offer optional paid features, including Pro subscriptions. Available plans, pricing, free trials if any, renewal terms, and billing details are shown in the Apple App Store or Google Play purchase flow before you confirm a purchase.

Purchases and subscriptions are processed by Apple App Store, Google Play, and RevenueCat. We do not directly collect or store full payment card details.

Subscriptions renew automatically unless canceled through the store account used for purchase before the renewal deadline required by that store. Deleting the app or deleting your Proof of Focus account does not automatically cancel an active subscription.

We may change paid features, pricing, plan names, or availability. Store rules may require notice or consent for certain price changes.

7. REFUNDS AND CANCELLATION

Refunds, cancellations, billing disputes, and chargebacks for app-store purchases are handled by the store where the purchase was made, such as Apple App Store or Google Play. We cannot guarantee refunds outside the relevant store's policies.

You can manage or cancel active subscriptions through your Apple App Store or Google Play account settings.

8. USER CONTENT

"User Content" means content or information you submit, upload, display, or make available through the Services, such as display names, avatar images, room names, friend interactions, support messages, and other profile or social information.

You keep ownership of your User Content, but you grant us a worldwide, non-exclusive, royalty-free license to host, store, reproduce, display, process, transmit, and use it as needed to operate, improve, protect, and provide the Services.

You are responsible for your User Content and must have the rights needed to submit it. We may remove or restrict User Content if we believe it violates these Terms, infringes rights, creates risk, or is otherwise inappropriate for the Services.

You must not use display names, avatar images, rooms, messages, or other User Content to post or promote sexual or exploitative material, child endangerment, hate speech, threats, harassment, bullying, impersonation, fraud, spam, illegal content, or material that infringes another person’s rights. Users can report content or users in the app and can block other users. We review reports and may remove content, issue warnings, suspend accounts, or permanently terminate access where appropriate. We do not reveal the reporting user’s identity to the reported user.

9. INTELLECTUAL PROPERTY

The Services, including the app, website, software, design, text, graphics, icons, images, trademarks, logos, and other materials, are owned by us or our licensors and are protected by intellectual property laws.

Subject to your compliance with these Terms, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to use the Services for personal, non-commercial use.

You may not copy, modify, distribute, sell, lease, reverse engineer, or create derivative works from the Services except where allowed by law or expressly permitted by us.

10. APP STORES AND THIRD-PARTY SERVICES

Your use of the mobile app may also be subject to rules and terms from Apple App Store, Google Play, your device platform, Firebase/Google Cloud, RevenueCat, Google Sign-In, Apple Sign-In, and other service providers.

Third-party services may change, suspend, or discontinue their services, which can affect Proof of Focus. We are not responsible for third-party services, stores, payment processors, operating systems, devices, or networks.

If you downloaded the app from Apple App Store or Google Play, the applicable store provider is not responsible for providing support or maintenance for the Services unless required by its own terms or applicable law.

For apps downloaded from the Apple App Store, Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Your license to use the app is non-transferable and is limited to use on Apple-branded products that you own or control, subject to the Apple Media Services Terms and Conditions. Apple is not responsible for addressing claims relating to the app or your possession or use of it, including product-liability, legal-compliance, consumer-protection, or intellectual-property claims, except where applicable law requires otherwise.

11. PRIVACY

Our Privacy Notice explains how we process personal information. By using the Services, you acknowledge that we process information as described in the Privacy Notice.

Privacy Notice: https://focus.ertdev.space/privacy/

12. ACCOUNT DELETION AND TERMINATION

You may stop using the Services at any time. You can delete your account from Profile Settings in the app. If you cannot access the app or the in-app deletion flow does not work, you may request account deletion at https://focus.ertdev.space/delete-account/ or by contacting habipertugruldagdemir@gmail.com.

Account deletion begins immediately and may continue in the background if all deletion steps cannot finish during the initial request. When completed, it deletes the account authentication record, profile data, uploaded avatar image, user-specific progress, friend relationships, friend requests, notifications, room-invite records, and other account-specific records. Shared room-history records needed to preserve another user's history may be retained only after the deleted account is anonymized or de-identified in those records. A pseudonymous device-level anti-abuse record used to enforce focus debt and free-use limits may remain for up to 90 days after device activity. Legal, security, backup, and app-store purchase retention limits may still apply. Account deletion does not automatically cancel active App Store or Google Play subscriptions.

We may suspend, restrict, or terminate your access to the Services if you violate these Terms, create risk for other users, misuse the Services, or if we are required to do so by law or by a third-party platform.

13. SERVICE AVAILABILITY AND CHANGES

The Services may depend on internet access, device permissions, sensors, app stores, Firebase/Google Cloud, RevenueCat, notification providers, and other third-party infrastructure.

We may update, modify, suspend, discontinue, limit, or remove any part of the Services at any time. We do not guarantee that the Services will always be available, uninterrupted, secure, accurate, or error-free.

We may correct errors, pricing information, descriptions, availability, entitlements, rewards, penalties, or other information at any time.

14. DISCLAIMERS

The Services are provided "as is" and "as available." To the fullest extent permitted by law, we disclaim all warranties, whether express, implied, statutory, or otherwise, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, reliability, availability, and security.

We do not warrant that focus detection, reminders, notifications, rewards, penalties, entitlement checks, progress tracking, or room events will be accurate, timely, uninterrupted, or error-free.

Some jurisdictions do not allow certain disclaimers, so some of the above may not apply to you.

15. LIMITATION OF LIABILITY

To the fullest extent permitted by law, we will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, including lost profits, lost data, lost progress, lost rewards, lost subscriptions, business interruption, device issues, or loss of goodwill arising from or related to your use of the Services.

To the fullest extent permitted by law, our total liability for any claim related to the Services will be limited to the greater of (a) the amount you paid to us for the Services in the six months before the claim arose, or (b) USD $10.

Some jurisdictions do not allow certain limitations of liability, so some of the above may not apply to you.

16. INDEMNIFICATION

You agree to defend, indemnify, and hold us harmless from claims, damages, losses, liabilities, costs, and expenses, including reasonable attorneys' fees, arising from or related to your use of the Services, your User Content, your violation of these Terms, your violation of law, or your violation of another person's rights.

We may assume exclusive defense and control of any matter subject to indemnification, and you agree to cooperate with us.

17. GOVERNING LAW AND DISPUTES

These Terms are governed by the substantive laws of Turkey, without regard to conflict-of-law rules, except where mandatory consumer protection law in your location requires otherwise.

Before bringing a formal claim, you agree to contact us at habipertugruldagdemir@gmail.com and try to resolve the issue informally. We will try to resolve disputes in good faith.

If a dispute cannot be resolved informally, and unless applicable consumer law requires another forum, the dispute will be finally resolved by arbitration under the United Nations Commission on International Trade Law Arbitration Rules then in force. The arbitration will have one arbitrator, the seat of arbitration will be Istanbul, Turkey, and the language of the proceedings will be English.

Nothing in these Terms limits rights you may have under mandatory consumer protection laws in your country, state, or region.

18. CHANGES TO THESE TERMS

We may update these Terms from time to time. The updated version will be indicated by the "Last updated" date at the top. If we make material changes, we may provide notice through the app, website, email, or another reasonable method.

Your continued use of the Services after updated Terms become effective means you accept the updated Terms.
