Mosaic is a photo-proof training challenge. Personal gym and body photos need clear rules.
Photos are private by default. They sync to your account so you can continue on another device. Sharing a 9:16 Mosaic card is an explicit action you choose. We do not publish your full photo library by default.
Once you have a username, your record has a public page at mrgren.store/m/your-handle. This is the page your shared cards link to, so anyone with the link — or your handle — can open it.
That page publishes the shape of the record only: your display name, which day you are on, how many days you trained, how many squares stayed empty, and which specific days were filled. It does not publish your photos, your thumbnails, or your notes — those stay private to your account and are never sent to the public page.
If you do not want a public page, do not share your handle, and contact us to have your record removed from public view.
You can try your first photo on this device before creating an account. Guest photos stay on the device until you sign in to save them to your account.
You can remove an individual day, archive a mosaic, or sign out on a device from the app. To delete your full account and stored mosaics, contact support through your signed-in account flow or email the site operator and request deletion of the username associated with your Mosaic.
Account authentication uses Supabase Auth. Mosaic challenge data and uploaded media are stored in the Mosaic backend used by mrgren.store (including object storage for photos). A local device cache may keep recent photos for offline viewing.
We use privacy-friendly product analytics (including Plausible when enabled) to understand landing visits, starts, first photos, shares, and return visits — not to sell personal photo content.
