Call Firewall Privacy Policy

The short version

Call Firewall does not collect, transmit, sell or share your data. The app does not request Android's Internet permission, so it cannot send anything from your phone. ArcHelm never receives your rules, your blocked-call history or your phone numbers.

What stays on your phone

The app stores the following in its private storage on your device:

• Your settings and rules: the Protection switch, blocked countries, allowed US states, the toll-free switch, custom prefixes and Allow List numbers.
• A record of each blocked call: the caller's number, the time, and the rule that blocked it.

Calls that are allowed are not recorded. This data is excluded from Android cloud backup and device-to-device transfer.

What the app does not access

The app does not access your contacts, call log, text messages, microphone, camera or location. It has no account, advertising, analytics or crash reporting.

How call screening works

When you make Call Firewall your call-screening app, Android gives it the number of incoming calls from people who are not in your contacts. The app checks that number against your rules on the phone.

Purchases

If you buy the app, Google Play handles the payment under Google's own privacy policy. The app itself receives no payment information.

Deleting your data

Use Clear History in the app, delete individual rules, or uninstall the app. Uninstalling removes everything the app stored.

Children

The app is not directed at children and collects no data from anyone.

Changes

If this policy changes, the new version will be posted here with a new effective date.
