Proof Fit
Privacy Policy
Last updated: October 13, 2026
Our commitment
HyperLabs AI ("we," "us," or "our") provides the Proof Fit mobile application and related services. This Privacy Policy explains what information we collect, how we use it, when we share it, and the choices available to you.
Information we collect
When you create an account, we may collect your name, email address, account identifier, and profile information such as age, height, weight, activity level, fitness goal, preferred units, and calorie or macro targets.
Food and nutrition information
Health and fitness information
With your permission, Proof Fit may read steps, workouts, exercise minutes, active energy, and related activity data from Apple Health. We use this information to display your activity progress, support accountability reminders, and provide features you request. The optional Apple Watch companion reads running distance and may save completed one-mile workouts to Apple Health with your permission.
Completed mile results include distance, start and finish times, and whether the attempt was recorded with iPhone GPS or Apple Watch. Results are saved on your device and, when you use account sync or friend challenges, are associated with your account on our secure backend.
We also save movement-session results and challenge records, such as challenge type, rep count or hold duration, points, and dates. Account sync can store these results with your account. If you choose to share a result or send a friend challenge, the selected result and challenge context are shared with the people or destination you choose. Mile personal bests use completed results saved on the current phone for the current account; rep records are best single sets, not accumulated daily totals.
We do not use HealthKit, fitness, or health-related data for advertising, marketing, or data mining.
Camera, movement, and photo information
The app may use your camera for movement challenges, barcode scanning, and food-photo analysis. Movement-challenge video frames and body-pose analysis remain on your device. We do not upload or store workout video, camera frames, or body-landmark history.
If a user chooses food-photo analysis and agrees to AI data sharing, the selected photo is sent through our secure server to OpenAI, LLC to estimate nutrition. We do not intentionally store the raw food photo on our backend after processing it.
Voice information
Location information
With your permission, the app uses precise location to search for nearby gyms, save a gym, support optional gym check-ins, and measure an outdoor one-mile run that you start on iPhone. Saved gym locations may sync with your account. You can use manual gym check-ins if you decline location access.
An iPhone GPS mile is recorded only when you start an attempt. Recording can continue in the background while the screen is locked, after GPS readiness and the countdown. Continuous run-location updates stop when the mile finishes or you cancel the attempt. Mile-run GPS coordinates are processed only in memory to measure distance; routes and raw run coordinates are not saved or uploaded. Shared run results contain distance, timing, recording source, and challenge context rather than a route.
Saved-gym check-ins are a separate feature. Optional automatic check-ins use saved gym locations and region monitoring (geofences) with Always location permission. Completing or cancelling a mile stops that run's continuous updates; it does not turn off gym region monitoring you have separately enabled. Gym names, saved locations, and visits may sync with your account; this is separate from the unsaved GPS points of a mile run.
Social, device, and purchase information
On-device paywall diagnostics
Proof Fit keeps a bounded on-device log of fixed paywall UI events and context, event time, Monthly or Annual plan labels, and an ephemeral identifier for a paywall presentation. It holds the latest 250 events. These diagnostics contain no account, health, food, or GPS payloads and have no remote analytics destination.
How we use information
- Provide calorie, macro, meal-planning, movement-challenge, outdoor-mile, saved-result history, gym check-in, social, and coaching features.
- Sync your account and app data across supported devices.
- Deliver requested notifications and friend-challenge alerts.
- Process and prevent abuse of subscriptions, AI credits, and founder offers.
- Respond to support requests, maintain security, and improve the reliability of the app.
- Comply with applicable law and enforce our terms.
AI Data Sharing and Your Consent
AI features are optional. Before Proof Fit sends information to OpenAI, LLC, the app shows an in-app disclosure that identifies OpenAI and asks the user to explicitly agree. Proof Fit sends only the information needed for the specific AI feature the user requests, through our secure server.
Depending on the feature, this may include:
- Food descriptions or voice transcripts the user asks Proof Fit to analyze.
- A food photo the user intentionally selects for food-photo analysis.
- Calorie and macro totals needed for a requested macro suggestion.
- Profile details and meal preferences needed for a personalized meal plan, including age, height, weight, activity level, goal, dietary restrictions, cuisine preferences, meal complexity, and budget preference.
Proof Fit does not send raw microphone recordings, Apple Health data, movement-challenge video, body-pose frames, precise location, passwords, Sign in with Apple credentials, or Apple payment information to OpenAI. Users can withdraw AI data-sharing permission at any time in the app at Settings → About → AI Data Sharing. Withdrawing permission stops future AI requests but does not remove existing food logs or other app data.
How we share information
We share data only as needed to operate the service:
- Supabase hosts authentication, account data, and synced app data.
- OpenAI, LLC processes the specific AI inputs described above only after the user opts in and requests food analysis, macro suggestions, meal plans, or food-photo analysis.
- Apple provides Apple Health, Sign in with Apple, push notifications, speech recognition, in-app purchases, and related platform services when you choose to use them.
- Map and location services help search for nearby gyms and support saved-gym check-ins.
Our service providers may process data only to provide services to us and must protect it with safeguards that are consistent with this policy. We do not sell personal information, use it for cross-app tracking, or share health and fitness information for advertising.
Data retention and deletion
We retain account and synced app data while your account is active. You can delete individual food entries and other saved records within the app where available.
You can delete your account in Settings → Account Actions → Delete Account. Account deletion removes your account and associated profile, food logs, plans, activity summaries, gym data, movement sessions, social data, and push-device records from our active systems.
The account-deletion flow also deletes account-linked AI entitlements and AI credit-usage records. It does not delete results you have already exported or shared outside the app, or completed workouts saved separately to Apple Health. You can manage Apple Health records in the Health app.
Saved mile results and the bounded paywall diagnostic log are separate on-device stores; deleting your account does not erase those local copies. Mile history shown in the app is scoped to the current account. Contact support if you need help with data on your device.
Apple manages its own payment and subscription records. Deleting your Proof Fit account does not cancel an active Apple subscription; use Manage Subscription in Proof Fit Plus, or Settings → [your name] → Subscriptions on your iPhone, to manage or cancel it.
Your choices
You can control camera, microphone, speech recognition, HealthKit, location, and notification permissions in Settings. You may use many features without granting every optional permission.
AI features are optional. Users can grant or withdraw AI data-sharing permission at any time in Settings → About → AI Data Sharing.
You can request help with your data by contacting us at info@hyperlabsai.com.
Security
We use reasonable administrative, technical, and organizational safeguards designed to protect information. No system is completely secure, and we cannot guarantee absolute security.
Children
Proof Fit is not directed to children under 13, and we do not knowingly collect personal information from children under 13.
Changes to this policy
We may update this Privacy Policy from time to time. We will post the updated version on this page and revise the "Last updated" date.
