Sinclair Calculator — Privacy Policy
Effective date: 4 October 2026
Sinclair Calculator performs weightlifting calculations entirely on your device. It does not collect or transmit personal information to the developer. It has no ads, accounts, analytics, tracking, server connection or internet permission.
Information on your device
You enter sex, bodyweight, age for Masters calculations, lifting totals and optional target scores. The latest 100 calculation records are stored in the app’s private storage on your device. Numeric inputs and recent history start empty on a fresh launch. Android may retain screen state when restoring an interrupted session. Automatic app data backup is disabled.
Sharing and external links
Sharing is optional. Share result opens Android’s chooser so you can select another app or recipient. The shared text contains the calculation, bodyweight, age where applicable, sex and scoring method. The destination’s privacy policy applies. Source links open in your browser, which may communicate with external websites.
Retention and deletion
Records stay on your device until replaced by newer entries (up to 100), you clear app storage in Android settings, or you uninstall the app. The developer cannot access or recover them.
