Privacy Policy

Last updated: July 17, 2026

Antigram is a private photo-sharing app for small circles of friends and family. It exists because sharing photos with the people you love shouldn't require an algorithm, ads, or handing your memories to an advertising company. This policy describes exactly what data the app handles.

Your photos are end-to-end encrypted

Photos are encrypted on your device (AES-256-GCM) before they are uploaded, and the keys to decrypt them are themselves encrypted so that only members of your circle can use them. We store the encrypted files, but we do not hold the keys — we cannot view your photos, and neither can anyone who gains access to our storage.

What we store

• Account info: your Apple sign-in identifier, the name you choose, your email (if you share it with Sign in with Apple), and your profile photo.
• Circle data: circle names, membership, and invite codes.
• Encrypted photos: the encrypted photo files and encrypted per-member keys. We cannot decrypt these.
• Captions, comments, and likes: these are stored on our servers (not end-to-end encrypted) so they can be shown to your circle.
• Notification data: a device push token and your notification preferences.

What we don't do

• No ads, ever.
• No selling or sharing your data with data brokers.
• No third-party analytics or tracking SDKs.
• No scanning or analyzing your photos — we can't.

Service providers

Antigram runs on Vercel (hosting), Neon (database), Cloudflare R2 (encrypted photo storage), and Apple (Sign in with Apple, push notifications). These providers process data only to run the service.

Deleting your data

Use Delete Account in the app's settings to permanently delete your account, your circles, and every photo you've shared. Individual photos can be deleted at any time and are removed for everyone.

Children's privacy

Antigram is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, contact us and we will delete it promptly.

Your rights

• Access the personal data we hold about you.
• Request correction of inaccurate data.
• Delete your data and account at any time using Delete Account in the app.
• Save your photos to your device at any time (they decrypt locally for you).

Changes to this policy

We may update this policy from time to time. We will note the "last updated" date above and notify you of material changes through the app or this website.
