Voice Guard - Scam Protection

A few seconds of audio can be enough for AI to imitate your voice and call your family. Voice Guard helps you prepare.

■ Voice protection
Record or pick a file and the app adds protection that is barely audible to people, making it harder for AI to copy your voice. Share the protected file instead of the original. You can also send files to the app from other apps to protect them.

■ Suspicious voice check (beta)
A beta screen is available for checking whether a suspicious voice may be AI-generated. Results are beta and for reference only, and newer AI voices may be missed. If the server can't be reached, the app shows a family-code-word fallback. Files are deleted as soon as the result is returned.

■ Suspicious call card
If someone posing as family urgently asks for money, see three steps at once: ask for the safe word, hang up and call back, then report. The card shows official reporting or advice contacts for your country.

■ Family safety
Set a family safe word and practice it. Invite your family with one tap; the invite never includes the safe word. Get an optional practice reminder every 30 days, which you can turn off in Settings. The safe word stays on your phone and is never sent to the server.

■ Automatic call-recording protection (optional)
Turn it on in Settings to protect new call recordings automatically. Family only mode processes only calls with family members you list.

■ Privacy
No sign-up. Input files are deleted when the job ends. Result deletion is requested as soon as the app receives them; undelivered results are automatically deleted about 10 minutes after completion. Advertising and analytics services may process advertising identifiers, usage events and error reports. Deleting voice files does not mean every operational log is deleted.

■ 10-second trial
On first launch, record 10 seconds of your own voice and protect it right away. Compare before and after to hear that it sounds nearly the same to people. Your first trial does not count toward the free limit.

■ Simple mode
Turn on Simple Mode in Settings for larger text and only three essential buttons.

Note: This raises the chance that AI misidentifies your voice; it does not guarantee 100% protection.
