You choose exactly what the browser shares
Starting opens the browser’s protected screen-sharing picker. Depending on browser and operating system, it may offer an entire display, one application window, or one browser tab. The page cannot silently bypass that picker. The browser’s sharing indicator remains the authoritative control, and ending sharing there also stops the recorder.
Audio support depends on the selected source
Shared tab or system audio is requested when selected, but some browsers expose audio only for certain tabs or operating systems. Optional microphone capture triggers a separate permission request and mixes it with shared audio when supported. Use headphones to reduce feedback, and obtain consent before recording other people, meetings, calls, presentations, or copyrighted media.
The recording stays temporary until downloaded
MediaRecorder assembles chunks in this tab and creates a temporary WebM or MP4 preview according to browser support. Gypes does not intentionally upload the capture. Reloading, closing, clearing, permission changes, low memory, device sleep, or browser failure can lose the entire recording, so stop and download promptly.
This is a convenience recorder, not a guaranteed archival, legal, compliance, security, broadcast, or evidentiary system. Verify video, audio, duration, and playback before relying on the file. Never capture passwords, private messages, financial data, confidential work, or people without proper authorization.
