Safe Privacy Gate — Check before you send

Stop accidental leaks before you hit Enter. Card numbers, API keys and your own watch words trigger a warning. On-device, no server.

When potentially sensitive information is detected, the extension displays a confirmation dialog before sending. You can then review the content and decide whether to continue. Safe Privacy Gate does not rewrite your text, automatically resend anything, or send your input to an external server. 【Key Features】 ・Local processing Checks are performed on your device. ・No external transmission Your input, detection results, file names, browsing history, and similar data are not sent to an external server. ・Does not rewrite your text The extension only displays a warning.
