PostureGuard monitors your posture in real time using your webcam, but everything stays on your machine. No accounts, no recordings, no cloud processing, just a short calibration, silent background monitoring, and native OS notifications when you start slouching. Built with Python + MediaPipe and fully open source.

I built PostureGuard because I kept catching myself hunched over my laptop for hours without noticing. I did not want another reminder app, browser extension, or wearable. I wanted something that would quietly run in the background, learn my baseline, and only speak up when I actually started slipping into bad posture. That is what this does: • short calibration on launch • real-time posture checks from your webcam • local processing only, no video storage • native system notifications when posture drifts • no accounts, no tracking, fully open source It is intentionally simple and privacy-first. Everything runs on your machine, and the webcam frames are discarded immediately after analysis. I would love feedback from people who spend long hours at a desk: does this solve the problem in a way that feels useful, or is there something missing that would make it genuinely stick?

Can you tune the notifications it so it doesn’t nag you every 30 seconds?

@karimbenkeroum Hey Karim, thanks for the feedback, I appreciate it!

Yes, the notification timing is adjustable, and I’m keeping an eye on that exact balance so it nudges without becoming annoying. If you have a sense of what feels better in practice, I’d love to hear it.

I'll make a new version later so this process is easier to change.

Thanks for checking it out and for the support!!
