Physical Activity Data

How we track your steps:

• Built-in Pedometer: Fitathon uses its own internal step tracker, which requires access to your device's motion sensors (pedometer). This is a core feature required for our fitness challenges.
• Background Activity: For accurate, all-day tracking, our app needs to run in the background. This allows us to count your steps even when the app isn't open on the screen.
• Data Usage: We only collect step count data. No other personal health metrics (like location, heart rate, etc.) are collected.

Camera and Face Verification (Push-up Challenges)

Push-up challenges use your device's camera to count repetitions and to confirm that the person performing them is you. This section explains exactly what that involves.

Your camera is never recorded.

• The camera is active only while a push-up session is on screen. It is not used anywhere else in the app.
• Every camera frame is analysed on your device, using on-device machine learning. Frames are discarded immediately after analysis.
• No photo or video is ever captured, uploaded, transmitted or stored — not on your device, and not on our servers.

What we do store: face geometry measurements.

• The first time you use a push-up challenge, you register your face. From that camera frame we calculate up to nine numeric ratios describing the proportions of your face — for example the distance between your eyes relative to the width of your face, and the positions and widths of your nose, mouth, chin, cheeks and ears measured relative to the distance between your eyes. How many are captured depends on which features are clearly visible in the frame.
• Only these numbers are saved to your user record. They are proportions, not an image, and a face cannot be reconstructed or recognised from them.
• We do not store facial images, facial embeddings, or any other facial data.

This is biometric data. Although the measurements are limited, they describe your face geometry and are used to confirm your identity, so we treat them as biometric information and handle them accordingly. We do not use them for any purpose other than the one described here, and we never sell or share them.

Why we collect it:

• Fair competition: push-up results count towards challenges and leaderboards. Comparing these ratios against your registered values confirms that the same person is performing the repetitions, so that someone else cannot complete a challenge on your behalf.
• Liveness check: at the start of each session we ask you to blink and smile. This confirms a live person is present rather than a photograph held up to the camera. The blink and smile are detected on your device and are not recorded or stored.

How long we keep it, and how to remove it:

• Your registered measurements are kept on your user record so that later sessions can be verified without asking you to register again.
• You can re-register your face at any time from the push-up tracking screen. Re-registering replaces the stored values.
• Deleting your account removes your user record, and with it your stored face measurements.
• You can also ask us to delete them at any time by contacting us at the address below.

You can decline. Camera access is requested only when you start a push-up challenge, and you may refuse or later revoke it in your device settings. Push-up challenges will not work without it. Step-based challenges and the rest of the app are unaffected.

Push-up Pattern Consistency

The same camera tracking that counts your repetitions also measures a few proportions of your body — for example the length of your forearm relative to your upper arm, and the width between your shoulders relative to your upper arm — along with your typical pace and depth per repetition. These are calculated from the same pose tracking used to count reps; no separate image or video is captured for this.

Why we collect it: to check that push-up sessions recorded on your account look consistent with your own past sessions. This exists because a daily limit alone cannot catch several short sessions, each individually unremarkable, performed by different people on the same account over the course of a day.

Two ways this is checked: your recent sessions are compared with each other for a consistent pattern over time, and separately, your very first usable session is kept on your account as a permanent reference point, so that even the first day of use is covered rather than only sessions after a history has built up. Nothing new is captured to create this reference — it is measured from an ordinary push-up session the same way every other one is.

What this can do: if a session's body proportions differ substantially from your account's history, that session's repetitions are still saved to your activity history, but are not added to any challenge or leaderboard. We will never silently keep a session's contest credit while flagging it after the fact — either it is credited at the time, or it is not, and you can tell which happened from the session's result screen.

Limits, stated plainly: this compares body proportions, not fine-grained identity — it is better suited to telling that a session came from a body of a different size than to distinguishing two similarly built people. It is one layer among several, not a guarantee.

This data is retained and deleted on the same terms as your other push-up session data, described below.
