About this app

Contacts Only™ is an unknown call blocker app that does the one thing your phone should already do: if a caller isn't saved in your contacts, your phone doesn't ring. Period.

Spam, robocalls, scam "warranty" calls, surveys - silenced before the first ring. People in your contacts always get through. No spam databases, no subscriptions, no accounts.

HOW IT WORKS
Contacts Only becomes your phone's call screening app. Android itself rings your saved contacts and hands everyone else to Contacts Only, which blocks them according to your settings.

• One switch: Block callers not in Contacts.
• Choose what blocked callers get: voicemail (on most carriers), an immediate decline, or silence.
• Optional: A repeat caller within a specified number of minutes rings through (for real emergencies). You can specify the number of calls and minutes.
• Optional private, on-device log of blocked calls.
• Works alongside Do Not Disturb: want only Favorites to ring? DND handles that; Contacts Only handles strangers.
• Numerous preferences and settings are included.

PRIVATE BY DESIGN
No internet access - nothing ever leaves your phone. Contacts Only can't even read your contact list: Android checks your contacts itself and only tells the app about unknown callers. No ads, no tracking, no analytics. One small one-time price - no subscriptions, ever.

Note: Blocking unknown callers means unknown-but-important calls (a doctor's office, a school) can be blocked too. The repeat-caller option is there for exactly that.

Contacts Only™ was designed by James R. Leichter and brought to you by Aptora Corporation. Learn more here: https://www.aptora.com/contactsonly
