PRIVACY FROM THE START

You stay in control

You can configure or disable features in the app. Location features explain how they work before activation and display a notification while running.

The Privacy Policy and Account Deletion pages are available in Portuguese.

Getting started questions

Search guidance from the app FAQ or choose a category.

How do I select a call rule?

Open RULES and double-tap the rule you want. The selected rule controls calls when Normal Protection is active. A single tap only expands or collapses its options.

View the screen on the website

Why was a call blocked or allowed?

Open LOGS and tap the call once. Its details show the classification, risk, reason, criterion, active rule and SIM when that information is available.

How can I get started without blocking my family?

Choose who should be able to call. If you need calls from couriers, doctors or other unsaved numbers, Unknown allows those calls subject to filters. Contacts allows Contacts, Favorites and the Allowlist. Double-tap your rule in RULES and check the header. Authorize call identification/blocking when Android asks. Arrange a test call and check LOGS. Avoid Block All: it also blocks family members and allowlisted numbers.

Must I keep the app open? Why are there ongoing notifications?

You do not need to keep a tab open for call protection. Travel Mode, location sharing and route recording are separate features that can run while the app is minimized, with service notifications. A notification shows activity but does not prove every feature is up to date. Stop a feature using its control in the app, not by force stopping, clearing data or uninstalling. Android battery restrictions may affect background operation.
