Gallery Diet Privacy Policy

Last updated: October 27, 2026

Gallery Diet ("the app") is made by Nitay Shporn. This policy explains what the app does with your data.

Your photos and videos

The app reads your photo library on your iPhone so you can decide what to keep and delete. Reviewing, sorting and deleting happens on your device. Your library is never uploaded.

Sharing with friends (optional)

If you use friends and sharing, the app signs you in anonymously with Google Firebase and stores the following in Google Cloud Firestore:

• the display name you choose and a 6-character friend code;
• if you add it, a one-way SHA-256 code made from your phone number (not the number itself), so friends who have your number can find you;
• photos or videos you choose to send to a friend (a compressed copy and a tiny blurred thumbnail), with any note you add, visible only to you and that friend;
• if you join the Friendly leaderboard, your weekly counts, streak and pace, visible to your friends.

Contacts (optional)

If you allow contacts access, the app turns your contacts' phone numbers into one-way codes and checks which of them use Gallery Diet. The numbers and codes are not stored.

What we don't do

No ads, no analytics or tracking tools, and no selling or sharing of data with third parties. Google Firebase processes data on our behalf only to run these features.

Deleting your data

You can delete shares you sent or received in the app and leave the leaderboard at any time. To delete everything linked to your account, send a request and it will be removed within 30 days.

Children

The app is not directed at children under 13.

Changes

If this policy changes, the new version will be posted on this page with a new date.
