CallSage : Trusted Call & SMS

CallSage is a phone app that helps you handle incoming calls: caller ID-style overlays, optional after-call actions, blocking tools, and dialer/contacts features. The in-app title may mention SMS; CallSage does not read, send, or block SMS messages—it can only open your existing SMS app when you choose that action.

Caller ID and call screen
• Incoming UI as full-screen or popup; you can adjust layout options where the app provides them.
• Appearance options for the call screen.
• Optional screen after a call ends.

Blocking and filtering (user-controlled)
• Block individual numbers and maintain a block list.
• Rules based on number patterns (for example prefix/suffix style rules), where available.
• Optional filters you can enable, such as country-related rules, international calls, private or hidden numbers, or numbers not in your contacts—subject to device support.
• Busy mode and do-not-disturb-style options you configure.
• Uses Android call screening or related phone APIs when supported; behavior can vary by device and OS version.

Optional online lookup
If you use online features, the app may request lookups to help identify unwanted or spam-like calls. Results can be incomplete or incorrect and depend on connectivity. CallSage is not a carrier service and does not guarantee identification for every number.

Dialer and contacts
• You may set CallSage as your default phone app on supported devices.
• Contact browsing and editing features depend on permissions you grant.

Permissions and data
Functionality may require access such as phone/call information, contacts, default phone or screening roles, display over other apps, notifications or foreground service (as required by the system), optional camera/media for images you add, and network access for ads, analytics, and optional cloud features. Actual prompts depend on your version of the app and Android.

Availability
Features and screens can differ by Android version, OEM software, and whether CallSage is set as the default phone app.
