Frequently Asked Questions

SitBlinkSip is a free, open-source desktop companion for developers and other computer-heavy workers. It watches your posture and blink rate through your webcam, runs quietly in the system tray, and reminds you when it's time to sit up, blink more, or grab some water.

No — just a computer with a webcam. SitBlinkSip Desktop is a native app that installs once and runs fully offline in the background. No account, no browser tab, and no extra hardware required.

SitBlinkSip Desktop runs computer-vision models directly on your machine to track posture and blink rate in real time. It doesn't show a live camera feed by default — press F6 to reveal a preview on demand — and it doesn't stream or save any video.

SitBlinkSip is designed to run lightly in the background alongside your usual dev tools — it only needs the webcam and a small amount of CPU for detection, and it never uploads anything, so there's no network overhead either.

SitBlinkSip Desktop is available now for Linux (.deb). Windows support is on the roadmap; macOS isn't currently planned. Check the GitHub releases page for the latest builds.

No. All posture and blink detection runs locally on your device. No video, frame, or image ever leaves your machine — there's no server for it to go to, since SitBlinkSip has no backend.

Your settings (like reminder intervals and alert preferences) are stored locally on your machine. SitBlinkSip doesn't require an account and doesn't send analytics or personal data to any server.

Yes. SitBlinkSip is completely free and open source under the MIT license — no subscriptions, no paywalls, no premium tier.

Yes — the source for the desktop app is on GitHub, and contributions, bug reports, and feature requests are welcome. See the GitHub repo for build instructions and the contributing guide.
