Privacy Policy
Last updated 7 August 2026 · GRYND is operated by Qajim Labs LLC.
The short version. Your camera never leaves your phone. Rep counting happens entirely on-device — no video or image is uploaded, stored or transmitted, ever. What we do store is your training numbers, so they survive you getting a new phone and so leaderboards can exist.
The camera
GRYND uses the camera to count repetitions. Frames are analysed on your device using Apple's on-device Vision framework and discarded immediately. No video, photo or still frame is recorded, saved, uploaded or sent to us or to anyone else. The only thing produced from the camera is a number: how many reps you did.
What we collect
| Data | Why |
|---|---|
| An account identifier | Either the identifier from Sign in with Apple or Google, or a random identifier generated on your device if you don't sign in. It is what ties your training to you. |
| Display name | The name you type in onboarding or that comes from your sign-in. It is shown to opponents, crew members and on leaderboards. |
| Profile picture (optional) | Only if you choose one. It is cropped and compressed on your phone, then stored on our servers and shown to opponents, crew members and on leaderboards. You can remove it at any time in Settings. |
| Training data | Completed sessions, rep counts, exercise types, durations, personal records, streaks, level and XP. This is the product. |
| Crew and room membership | Which crew you're in and who else is in it, so a shared weekly total can exist. |
| Push notification token | Only if you allow notifications. Used solely to tell you when someone in your crew starts a session. |
| Usage analytics | Which screens are opened and which features are used, so we can tell what is working. Sent to PostHog. It does not include your camera data or the contents of anything you type. |
What we never collect
- Video, photos or camera frames.
- Your location.
- Your contacts, calendar, health records or Apple Health data.
- Payment card details. Apple handles payment; we never see a card number.
Who processes data for us
- Cloudflare — hosting, database and file storage for your profile, sessions and profile picture.
- RevenueCat — subscription status. It receives your account identifier and the purchase information Apple provides.
- Apple — payment, subscription billing, Sign in with Apple and push delivery.
- Google — only if you choose Google to sign in.
- PostHog — product analytics.
We do not sell your data, and we do not share it with advertisers or data brokers.
What other people can see
Your display name, level, rank and profile picture are visible to people you duel, people in your crew or room, and anyone viewing a leaderboard you appear on, along with the rep counts that put you there. Nothing else about you is visible to other users.
How long we keep it
Your training data is kept while your account exists, because losing it is the thing the account is for. Delete your account and it is removed from our servers. Analytics events are retained by PostHog under their own retention schedule.
Deleting everything
Open the app, go to Settings → Delete account. That deletes your profile, sessions, records, weekly totals, crew membership, push token and profile picture from our servers, and wipes the copy on your phone. It cannot be undone.
If you can no longer open the app, email support@gryndnow.com and we will delete it for you. An active subscription is billed by Apple and must be cancelled separately in your Apple account settings — deleting your GRYND account does not cancel it.
Children
GRYND is not directed to children under 13, and we do not knowingly collect data from them. If you believe a child has given us data, email us and we will remove it.
Your rights
Depending on where you live, you may have the right to access, correct, export or delete your personal data, and to object to certain processing. Deletion is built into the app. For anything else, email support@gryndnow.com and we will respond within 30 days.
Changes
If this policy changes in a way that materially affects you, we will say so in the app before the change takes effect. The date at the top always reflects the current version.
