StackUp ("the app") is a workout tracker for Android. This policy explains what data the app handles. In short: StackUp does not collect, transmit, or share any personal data.
None. StackUp does not require an account, sign-in, or any personal information to use.
All the data you enter — your exercises, splits, workout sessions, weights, reps, and settings — is stored locally on your device in a private app database (SQLite). This data never leaves your device. It is not uploaded to us or to any third party. When you uninstall the app, this local data is removed by the operating system.
None. We do not sell, share, or transmit your data to anyone. StackUp contains no advertising SDKs and no third-party analytics.
StackUp does not require an internet connection to function, and it does not send your
workout data anywhere. The app requests standard Android network permissions
(INTERNET, ACCESS_NETWORK_STATE) only so that system-provided
services can operate — specifically Google's official in‑app review prompt and standard
platform diagnostics. No personal or workout data is transmitted through these.
StackUp is not directed at children and does not knowingly collect any data from anyone, including children.
