Privacy

Updated 15 October 2026. Henry Delacroix, in Belgium, is responsible for the data Blockello keeps.

What we keep

Your account: the ID, email and first name Sign in with Apple gives us. Your cards and decks, and which AI apps you connected. Your progress: for each card you have answered, when you last answered it, how well you know it and when it comes back, so a new iPhone gets it back; your AI can’t see it. For public decks: the deck with your first name as its author, who added or liked it, reports and blocks. And a scrambled form of your network address, not linked to your account, to limit abuse.

What stays on your phone

The apps you block. Without an account, your progress too. The app has no ads, analytics or tracking.

Who else handles it

Cloudflare runs our server and database. Apple handles sign-in. What you tell your AI is covered by that AI’s own privacy policy. We don’t sell anything.

How long

Deleted cards are erased after 30 days. Everything else is kept until you delete your account in Settings. Cards others already added from your public decks stay with them.

Your rights

Write to support@blockello.app for a copy of your data, a correction or anything else. You can also complain to the Belgian Data Protection Authority.
