How our lists work

Spam number list

• A number is only listed after enough independent reports from different devices at different times.
• Repeat reports from the same device or network count less; sudden bursts are reviewed.
• Labelling ("Possible spam") can be automatic. Central blocking happens only after human review.
• If you think a number is listed by mistake, you can object.

SMS filtering

• Rules are signed; the app only accepts rule packs with a verified signature.
• A sender name alone is never treated as a sign of trust; sender names can be taken over.
• A "Spam" decision usually needs several signals. Only wording that scammers alone use, such as illegal betting bonuses, is enough by itself.

Your lists

• Only you fill your allowed and blocked lists: by hand, or by answering Block or Allow after a call.
• Reporting "Spam" never blocks the sender automatically.
• "Not spam" doesn't add the sender to your allowed list; it only ignores weak spam signals.
• You can see every list in the app and remove any entry with one tap.

Reports are sent only with your explicit consent.
