Your camera, your choice

Sign Chat requests video only after you press Turn on camera. It never requests your microphone.

• Up to 48 sampled frames (about six seconds) are kept in browser memory, with a 3.5 MB encoded-data limit. The oldest frames are discarded when a limit is reached.
• Imported videos (½–6 seconds, up to 20 MB) are decoded on your device. The app samples still frames, excludes audio, and does not upload the original video. Importing alone does not send anything.
• Pressing Send this phrase, or enabling Live mode, sends frames into your ChatGPT conversation for model interpretation. Those images are subject to your ChatGPT account’s data controls and retention.
• The Sign Chat server serves code and plugin metadata. There is no media upload endpoint, camera storage, tracking script, or analytics in this app. A service-wide request limiter uses a fixed route key, not user identifiers. Hosting infrastructure may log ordinary request metadata such as time, IP address, and URL.
• Stop camera, hiding the page, and closing the widget release the camera and clear unsent frames. Frames already sent to ChatGPT remain in the conversation.
• In the standalone preview, Save phrase image downloads a contact sheet onto your device. You choose whether to attach it in ChatGPT and when to delete it.
