Blitz ("the app", "we", "us") is an offline-first fitness and nutrition tracker. This policy explains what data the app handles and how. The short version: your data stays on your device.
None. Blitz does not require an account, does not log you in, and does not transmit your personal data to us or to any third party. We do not run analytics, advertising, or tracking SDKs.
Everything you enter stays locally on your iPhone and Apple Watch, including:
This data is stored using your device's local storage and is never uploaded to a server. If you delete the app, this data is removed with it.
Blitz uses your camera and photo library only to scan food for calorie and macro estimation. Image recognition runs entirely on your device using Apple's on-device machine learning (Core ML). Your food photos are never uploaded, shared, or sold.
Workout and nutrition data you enter is stored locally and used only to power the app's tracking, analytics, and progress features. It is not shared with us or any third party.
Blitz is rated for general audiences and does not knowingly collect data from anyone. Because we collect no data at all, no special handling for children's data is required.
If this policy changes, we will update the date at the top of this page. Continued use of the app after changes means you accept the updated policy.
