Need help with CallCheck? We're here for you.
When you receive a call from an unknown number, CallCheck instantly analyzes your device's call history, SMS records, and contacts. If no local data is found, it searches the web for information about the number. Results are presented as a decision card within 3 seconds.
No. All analysis happens on your device. We do not operate a central database or collect any phone numbers. See our Privacy Policy for details.
Open Google Play Store → Tap your profile icon → Payments & subscriptions → Subscriptions → CallCheck → Cancel subscription.
These permissions allow CallCheck to analyze your existing device data to provide decision support. Without them, the app cannot check if a number has previously called you or if it's a saved contact.
Currently, CallCheck is available on Android only. iOS does not provide the CallScreeningService API needed for real-time call analysis.
CallCheck works in 190+ countries. The app automatically detects your country and adjusts phone number formatting and search sources accordingly.
