About this app

KeepCallsSafe rejects calls from "No Caller ID", "Private", "Restricted" and "Unknown" numbers before your phone even rings. If you like, it can also reject international numbers that aren't in your contacts.

• One tap to set up: No hunting through phone or carrier settings. Turn protection on and you're done.
• Your contacts always get through: People you know are never blocked, and you can always allow any number or a whole country with a single tap.
• Private by design: Every call is checked on your phone. Your calls and contacts are never uploaded. No ads, no tracking.
• Clear pricing: Google Play shows the exact price and the date of your first payment before you confirm. We remind you 3 days before the free trial ends.

60 days free, then $9.99 a year · cancel anytime. Sales tax is added at checkout where it applies; Google Play shows the exact total before you pay.

Good to know: KeepCallsSafe blocks calls that hide their number and, if you turn it on, calls from abroad. It doesn't judge calls that show a normal US number, so spam from a spoofed local number still rings. Your carrier's spam filter and KeepCallsSafe work well together.

Cancel your subscription: Google Play → your profile → Payments & subscriptions → Subscriptions → KeepCallsSafe → Cancel. Protection keeps working until the end of the period you've paid for.

Does it work on my phone?
KeepCallsSafe works on Android 10 or newer, on any brand. We have tested it on Samsung Galaxy and Xiaomi/Redmi phones. Phones and carriers differ, so you get 60 days free to check that it works for you before you pay anything.

Will people in my contacts still get through?
Yes, always. People saved in your contacts are never blocked, and you can mark any other number as "always allow" with one tap.

Can I block international numbers?
Yes, if you want to. KeepCallsSafe can reject calls from outside the US that aren't in your contacts, and you can choose countries whose calls always get through, for example where your family lives.

Does KeepCallsSafe upload my calls or contacts?
No. Every call is checked on your phone. Your calls and contacts never leave it. There is no account, no ads and no tracking, and Google Play lists the app as collecting no data.

How much does it cost?
The first 60 days are free. After that it's $9.99 a year in the United States, plus sales tax where it applies; Google Play shows the total before you confirm. You can cancel anytime in Google Play, and we remind you 3 days before the free trial ends.

Something not working on your phone? Use "Report a problem" in the app. If your report helps us fix a problem and you then confirm on your phone that it's gone, you get KeepCallsSafe free for life.

For Android phones (Android 10 or newer).
