Terms of Use

Updated 26 September 2026

Tennistory is a racket reference and personal care log. Catalog specifications, string-life estimates, weather scores and acoustic tension estimates are informational; they do not replace manufacturer guidance, a stringer’s judgment, or safety advice.

Subscriptions

Price, billing period and any trial or introductory offer are shown on the App Store confirmation sheet. Apple’s terms govern payment, renewal, cancellation and refunds. Deleting the app does not cancel a subscription. The Apple Standard License Agreement applies.

User content

Racket details and photos you submit must be yours to use and must not impersonate a brand, expose someone’s personal information, or break the law. Submissions and corrections are published only after developer review.

Points

Accepted submissions and corrections earn points that can be redeemed for PRO time. Invite friends: when a friend enters your code within 7 days of first installing and after adding a first racket, you both earn points. Each device can enter one code, and there are limits per network and per day. Points have no cash value and cannot be transferred or withdrawn. Points gained through abuse, repeated invite claims after reinstalling or erasing data, or misleading submissions may be removed.

Disclaimer

Check important decisions against your real equipment and conditions. The app is provided as available and may be limited by data sources, device capabilities or permissions.
