Terms of Service
These terms cover the TChess Android app and tchess.app. By using TChess you agree to them.
1. TChess
TChess is a chess training app: puzzles, bots, lessons, openings, analysis and game review. There is no advertising.
2. Free and Pro
Most of TChess is free with no account. TChess Pro is optional and adds more: more bots, the AI Coach, the opening tools, the Weakness Trainer and premium boards and pieces. It is sold as a monthly or yearly subscription or a one-time lifetime purchase. Where a free trial is offered, it is shown before you pay.
In the app, Google Play bills you and its terms and refund policy apply. On tchess.app, our payment partner bills you as the merchant of record; see the Refund Policy. You can cancel a subscription at any time; it stays active until the end of the period you paid for.
3. Your account
An account is optional. It keeps your progress and Pro across devices. Keep the email account you sign in with secure — anyone who can open it can sign in as you.
4. Fair use
Do not try to break or overload the service, access other people’s accounts, manipulate ratings, or redistribute a modified app. We may suspend an account that does.
5. Your data
Your games and progress are yours. How we handle data is in the Privacy Policy, which is part of these terms. You can delete your account at any time.
6. Credits
Some parts of TChess are used under open licences, credited in the app under Settings → About. Those licences apply to those parts.
7. No warranty
TChess is provided as it is. We work to keep it available and correct, but we cannot promise it will never be interrupted or free of errors.
8. Liability
To the extent the law allows, we are not liable for indirect losses from using TChess, including lost progress. Nothing here limits liability that cannot lawfully be limited.
9. Changes
We may update these terms; the date above changes when we do. Using TChess after a change means you accept it.
10. Law
These terms are governed by the laws of Pakistan.
