TERMS OF
USE

Last updated: September 2026

1
Acceptance

Agreement to terms

By downloading or using Paper Track, you agree to these Terms of Use. If you do not agree, do not use the app.

2
License

Your license

We grant you a limited, non-exclusive, non-transferable license to use Paper Track for personal, non-commercial purposes on devices you own or control.

3
Restrictions

What you may not do

You may not copy, modify, or distribute the app; reverse engineer or attempt to extract the source code; use the app for any unlawful purpose; or interfere with the app's security or integrity.

4
Online Features

Leaderboards and profile

The app uses Google Firebase to provide a daily competition leaderboard, a daily challenge ranking, and a player profile (nickname and avatar). These features require a network connection. If Firebase is unavailable, you can still play locally; online rankings may not update until the connection returns.

Nicknames you set are public on the daily leaderboard. Do not use a nickname that is unlawful, impersonates someone else, or contains offensive or infringing material. We may remove or reset a nickname that violates these terms.

5
Advertisements

Third-party ads

The app displays third-party advertisements via Appodeal. Third-party advertisers are responsible for the content and data practices of their advertisements.

6
Analytics

Usage data

The app uses Amplitude to collect anonymous usage analytics — such as session data and in-app events — to help us improve the experience. Cloud features also rely on Firebase, as described in our Privacy Policy. By using the app, you agree to that data collection.

7
Disclaimer

No warranties

To the fullest extent permitted by applicable law, the app is provided "as is" without warranties of any kind. We do not guarantee uninterrupted or error-free operation, including availability of leaderboards or other online features.

8
Limitation of Liability

Limits on our liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the app.

9
Termination

Ending your license

We reserve the right to terminate or suspend your license to use the app at any time if you violate these Terms of Use.

10
Changes

Updates to these terms

We reserve the right to modify these terms at any time. We will notify users of significant changes by updating the date at the top of this page. Continued use of the app after changes indicates acceptance of the updated terms.

11
Governing Law

Jurisdiction

These terms are governed by the laws of the Republic of Belarus.
