Blocking does not work (Android)
Check that Who Called is set as the call screening app: open the app, Home screen, and follow the “Enable protection” prompt. Also make sure the list is up to date (“Update the list” button).
Blocking does not work (iOS)
Check that the extension is enabled: iOS Settings → Apps → Phone → Call Blocking & Identification → enable Who Called. After a list update, iOS may take a moment to reload the extension.
Delete my data
In the app: Settings → “Delete my data”. The action is immediate and erases your reports, your game scores and your device record from our servers. Details on the “Data deletion” page.
My number is wrongly reported
If you are responsible for a listed number and dispute its score, write to privacy@who-called.com: we remove the number after verification. Prefixes from the official ARCEP list cannot be removed.
