Please read these Terms of Use (“Terms”) carefully before using any of my mobile applications (the “Apps”). By downloading, installing, or using the Apps, you agree to be bound by these Terms. If you do not agree to all of these Terms, you may not access or use the Apps in any manner.

Introduction I, Egor Kudriavtcev, a solo developer (“I”, “me”, “my”, or “Developer”), operate one or more mobile applications built with Flutter and Dart (collectively, the “Apps”). These Terms form a legally binding agreement between you and me regarding your use of the Apps.

Your use of the Apps is also subject to my Privacy Policy, which is incorporated by reference. If you have questions about these Terms, contact me at support@ekudr.info.

These Terms include important information about limitations of liability, a class action waiver, and resolution of disputes by binding individual arbitration instead of court (see Arbitration Agreement below).

ARBITRATION NOTICE AND CLASS ACTION WAIVER: EXCEPT FOR CERTAIN TYPES OF DISPUTES DESCRIBED BELOW, YOU AGREE THAT DISPUTES BETWEEN YOU AND ME WILL BE RESOLVED BY BINDING, INDIVIDUAL ARBITRATION, AND YOU WAIVE YOUR RIGHT TO PARTICIPATE IN A CLASS ACTION LAWSUIT OR CLASS-WIDE ARBITRATION.

Changes to These Terms I may update these Terms from time to time to reflect changes in the Apps or legal requirements. I will post the revised Terms on my website (ekudr.info) with a new “Last revised” date and may notify you in the Apps or by other means. Your continued use of the Apps after the changes take effect means you accept the updated Terms. If you do not agree, stop using the Apps.

Eligibility and Account You must be at least 13 years old (or the minimum age required in your country) to use the Apps. If you are under the age of majority in your jurisdiction, you need parental/guardian consent and they must agree to these Terms on your behalf.

If the Apps allow account creation (e.g., via email/password through Firebase Authentication), you agree to provide accurate, current information. You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. Do not share your account. I reserve the right to suspend or terminate accounts for violations.

Use of the Apps You may use the Apps only for your personal, non-commercial purposes and in compliance with all applicable laws. You agree not to:

• Copy, modify, reverse engineer, decompile, disassemble, or attempt to derive source code from the Apps.

• Use the Apps in any way that could damage, disable, overburden, or impair them.

• Attempt to gain unauthorized access to the Apps, accounts, or systems.

• Use automated means (e.g., bots, scrapers) to access or collect data.

• Transmit viruses, malware, or harmful code.

• Infringe any intellectual property or other rights.

• Engage in fraudulent activity, including abusing in-app purchases or subscriptions.

Violation of these restrictions may result in termination of your access.

In-App Purchases and Subscriptions The Apps may offer in-app purchases or subscriptions (e.g., premium features), processed through RevenueCat and the relevant app store (Google Play, Apple App Store).

Payments are handled by the app store or RevenueCat. You agree to their payment terms. Subscriptions may auto-renew unless canceled per the store's rules (e.g., before the end of the current period). No refunds except as required by law or store policy.

I may change pricing or availability with notice where required. All purchases are final unless stated otherwise.

Intellectual Property The Apps, including code, design, text, graphics, and features, are owned by me or licensed to me and protected by copyright, trademark, and other laws. You receive a limited, non-exclusive, non-transferable license to use the Apps as intended on your devices. You may not copy, distribute, sell, or create derivatives without my written permission.

User Content (if applicable) If the Apps allow you to submit content (e.g., feedback, data), you grant me a royalty-free, perpetual, irrevocable, worldwide license to use, modify, and display it as needed to operate and improve the Apps. You represent you have rights to any content you submit.

Third-Party Services The Apps use Firebase (Google) for authentication, analytics, crash reporting, and storage, and RevenueCat for purchases/subscriptions. Your use is subject to their terms/privacy policies. I am not responsible for their services.

Links and External Sites The Apps may link to third-party sites/services. I do not control or endorse them and disclaim liability for their content or practices.

Termination You may stop using the Apps anytime. I may suspend or terminate your access for any reason, including violations, with or without notice. Upon termination, your license ends, and provisions like liability limitations, indemnity, and arbitration survive.

No Warranty / Limitation of Liability THE APPS ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. I DO NOT WARRANT THAT THE APPS WILL BE ERROR-FREE, SECURE, OR UNINTERRUPTED.

TO THE FULLEST EXTENT ALLOWED BY LAW, I SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES (INCLUDING LOST PROFITS, DATA LOSS), EVEN IF ADVISED OF THE POSSIBILITY. MY TOTAL LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID ME IN THE 12 MONTHS BEFORE THE CLAIM (OR $100 IF NOTHING PAID). SOME JURISDICTIONS DO NOT ALLOW THESE LIMITATIONS, SO THEY MAY NOT APPLY TO YOU.

Indemnity You agree to indemnify and hold me harmless from claims, losses, damages, liabilities, and expenses (including attorneys' fees) arising from your use of the Apps, violation of these Terms, or infringement of third-party rights.

Governing Law and Arbitration These Terms are governed by the laws of Pennsylvania, USA (where your IP is located), without regard to conflict of laws principles.

Arbitration Agreement Any dispute arising from these Terms or the Apps shall be resolved by binding individual arbitration in Pennsylvania under the rules of the American Arbitration Association (or similar). You waive class actions, consolidated actions, or jury trials. You may opt out by emailing support@ekudr.info within 30 days of accepting these Terms, with your name, email, and clear opt-out statement.

If arbitration is unenforceable, disputes go to courts in Pennsylvania. Small claims court is allowed where eligible.

Miscellaneous These Terms are the full agreement. If any part is invalid, the rest remains enforceable. I may assign these Terms; you may not without my consent. No waiver of any breach is a waiver of future breaches.

For Apple App Store apps (if applicable): These Terms are between you and me only, not Apple. Apple has no obligation for maintenance/support. Any warranty claims go through Apple for refund (if paid). I handle third-party IP claims
