How it works

With the contacts option on, numbers saved in your address book go straight through. The app asks for the contacts permission, and you can turn this option off whenever you like.

By default, the first call from an unknown number is rejected. If you prefer, you can silence the call instead of rejecting it.

The second call is only let through if it happens within 24 hours of the first blocked one. When that happens, the number is validated. If about 7 days pass without new calls, the validation expires and the number is blocked on the first attempt again. Anyone who must always get through should be marked as allowed in the app. There is no automatic permanent release.

A number you allow manually takes precedence over the automatic rule. A number you block manually stays blocked, even if it is validated, is a contact or is on its second attempt. The history gathers every decision and can be filtered by all, blocked or allowed, by date and by search. The allowed list can be exported and imported as JSON.

The filter uses call screening. Without that permission, it does not work. The “Protection active” notification stays on with the app closed and after the phone restarts. You can turn it off from the notification itself, and the choice is saved. Private numbers follow your setting: block or let through. Without internet, filtering keeps running on the device.

With the schedule on, outside the configured period the call goes through and the history records “outside schedule”. Protection only applies with the switch on and, if the schedule is active, within the chosen hours.

On the Silver and Gold plans, you generate a ZIP file on the device with settings, lists, validated numbers and history. On Gold, the backup also goes to the cloud, right away or daily or weekly. The password is optional and stays only on the phone. Up to 5 backups, with one active device per account.

It is optional and uses Google sign-in. When you mark a call as spam, the report is sent. The permanent record keeps a cryptographic identifier, not the number in plain text. When 3 or more different devices report the same number, other participants may see an alert after a call that was already blocked. The badge neither allows nor blocks anyone. The “Not spam” option opens a dispute.

On the free plan, the call filter works with ads, with your consent. Silver is a one-time payment: no ads and local backup. Gold is a subscription with everything in Silver, plus cloud and time schedules. Buying or restoring a purchase requires Google sign-in, and the Play Store confirms the plan. Master and donations are not store plans.

Filtering does not send numbers to servers that decide whether a call comes through. The app is available in Portuguese, English and Spanish. If something is not filtered, the protection diagnostics are in the app itself. The manufacturer and the device version can change how screening behaves. The app does not promise perfect filtering.
