Description
Corta Spam is your phone app. It replaces the default dialer, receives every incoming call, and screens it against rules you write yourself, before your phone rings.
No ads. No tracking. No accounts. No network access at all — every rule and every log entry stays in a database on your device, and the app has no code that could send it anywhere.
WHEN A CALL COMES IN
Corta Spam is the app that rings. It shows the caller full-screen with Answer and Decline, over the lock screen when your phone is locked, and names the caller from your contacts. While you are on a call you can leave the app and get back to it from the notification.
WHAT YOU CAN BLOCK
• Specific numbers — with a label so your call log tells you why • Patterns — block a whole range with wildcards, like +34900* or *1234 • Countries — block a dialling code you never expect a call from • Quiet hours — silence everything on a schedule, except your allowlist • Repeat callers — block a number after it tries too many times in a short window • A bundled spam list — known scam dialling codes, shipped inside the app
Your contacts and your allowlist always come through, and a number you block manually stays blocked even if it is in your contacts. You decide what wins.
WHAT HAPPENS TO A BLOCKED CALL
Your phone stays silent. The call log records what happened and which rule made the decision, in your language. You can call back or copy any number straight from the log.
You choose what happens to a number no rule matched: let it through, block it, or let it through but flag it for review. There is also an optional setting to let an unknown number through once it has tried several times — because a real person calling repeatedly is usually not a robocall.
PRIVACY
The app requests no access to your system call log, SMS, storage, location or camera. It reads your contacts only to recognise callers you know, and that never leaves the device. The microphone is requested only if you switch auto-responder recording on, which ships off; recordings stay in the app's private storage and are never transmitted.
There is no analytics SDK and no crash-reporting SDK. The full privacy policy is published alongside the source code, and you can check every claim in it against the code.

NOTE ON PERMISSIONS
Corta Spam is a phone app, so it must be set as your default phone app. That is the only way Android lets an app receive a call, show it, and screen it before it rings — it is how the app works, not an extra request.
For the same reason it shows the incoming call full-screen over the lock screen, the way any phone app does. Without that, a call arriving while your phone is locked could not be answered.
The auto-responder is experimental. It answers a blocked call and plays a greeting, but on modern Android the caller may not hear it clearly; treat it as a bonus, not a feature to rely on. It can optionally record the message a caller leaves — to turn that on, your own greeting must contain a line telling the caller they are being recorded.
Recent changes: Important fix: a blocked call now always ends. If something answered it before the app could reject it — a pocket, a headset button, the system — the call stayed connected even though the notification said "Blocked call". Now it is always hung up.
The auto-responder also hangs up when the greeting never plays, for example on a phone with no voice for your language.
Switching it on now asks for confirmation, and says your phone will answer by itself, on speaker.
