Your photos stay yours.

What we keep

which twin? stores your Google account ID, email, family memberships, children’s names, manually drawn face labels, and quiz answers in its private database. The administrator can see family results; members can see only their own.

Google Photos

Only the administrator connects Google Photos. Uploads are sent through which twin? to an app-created album in that Google account. Photo bytes pass through the server in memory and are not saved in app storage. Photos are fetched from Google when displayed. Your browser receives the photo to show it, with caching disabled.

Google tokens are encrypted in the database. which twin? requests access only to upload photos and read content created by this app. It does not use automated facial recognition or train AI models.

Access and deletion

The administrator can remove a family member’s access, hide photos from quizzes, and disconnect Google Photos. Deleting a photo in Google Photos stops it loading here. To delete your account information and quiz history, contact your family administrator. Uploaded photos remain in Google Photos until you delete them there.

which twin?’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
