Getting started questions
Read common questions or open the Help Center to search for other topics.
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.
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 Callers allows those calls subject to filters. Contacts allows Contacts, Favorites and the Whitelist. 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 whitelisted numbers.
Must I keep the app open? Why are there ongoing notifications?
You do not need to keep the app on screen for call protection. Travel Mode, location sharing and route recording are separate features that can run while the app is minimized, depending on permissions and settings. A notification indicates activity but does not guarantee that all data is up to date. Stop a feature using its control in the app. Do not force stop, clear data or uninstall as the first troubleshooting step. Android battery restrictions may affect background operation.
