Before contacting support

These solve the most common beta issues.

"The app won't open my camera"

  1. Close other apps that may be using the camera, such as Zoom, FaceTime, Teams, or browser tabs.
  2. Make sure ScreenGuardian has camera permission in your system settings.
  3. Restart ScreenGuardian.
  4. If it still cannot open the camera, email us with your computer type, app version, and camera model if you know it.

"The camera preview is slow or looks split on Windows"

This is usually a webcam driver/backend issue rather than an account or website issue. Email us your Windows version, app version, webcam model, and whether the camera is built in or plugged in by USB. If we ask for diagnostics, run this from the ScreenGuardian source folder on that machine:

python scripts/diagnose_camera.py --out camera-diagnostics/windows-webcam

The script writes local timing files and thumbnails so we can see which camera backend is both fast and visually correct. Nothing is uploaded automatically.

"ScreenGuardian seems inaccurate"

  • Re-run calibration if your desk setup changed.
  • Make sure your face and upper body are visible to the camera.
  • Avoid strong backlight, such as a bright window behind you.
  • Start from a comfortable neutral posture, then let ScreenGuardian guide from there.
  • Open the feature list if you want to confirm what the current beta looks for: https://screenguardian.pages.dev/features.

"Does ScreenGuardian use my microphone?"

No. ScreenGuardian does not need microphone permission and does not listen to your room, calls, or conversations. The app uses visual posture and distance feedback from your camera; camera frames stay on your device and are not stored by ScreenGuardian.

"What is included if I send feedback or a crash report?"

Both are optional and only sent when you choose to send them. A feedback message includes what you type, plus any screenshots or logs you attach yourself — so review attachments before sending, since a screenshot can capture whatever is on screen. Crash reports are off unless you turn them on, and are limited to technical failure details. Neither feedback nor crash reports include camera frames, posture or habit history, microphone audio, or your local files.

"An update appeared, but I am not sure it installed"

Quit ScreenGuardian completely and reopen it. If your system shows an installer or confirmation prompt, follow the on-screen steps.

"My invite says it was revoked"

It means that invite is no longer active. Email us and we can check whether you should receive current access.

"Windows warned me about the installer, or my antivirus flagged it"

During beta the installer may not yet be signed with a certificate that Windows SmartScreen or every antivirus engine already recognizes, so you may see a "Windows protected your PC" prompt or a security flag. That is about the missing signature, not malware. Only download ScreenGuardian from the official sources — the download page and the GitHub releases it links to. If SmartScreen appears, choose More info → Run anyway. On macOS, if you see a "damaged app" message on an unsigned beta build, follow the steps shown in the download instructions. If your antivirus quarantines the installer, re-download it from the official page or email us.

"Will my history move to a new computer?"

No — and that is by design. Your posture and habit history, charts, and settings are stored only on the computer where they were recorded; ScreenGuardian does not sync them to the cloud, because camera-derived data never leaves your device. When you switch computers, your account and access follow your sign-in, but local history stays on the old machine. There is no cloud backup of local history to restore from.

"Can I use ScreenGuardian on a work or school computer?"

ScreenGuardian uses your camera, and some workplaces and schools restrict camera apps or control which software may run on their managed devices. Check your organization's policies before installing on a device you do not personally own — following those policies is your responsibility. On a personal computer, ScreenGuardian needs only the camera permission you grant.

Leaving ScreenGuardian: quit, erase data, unlink, or delete account

These are four separate things, smallest to largest:

  • Quit the app. Camera capture and detection stop immediately. Nothing else changes. (Cmd-Q on macOS, the tray menu's Quit, or Alt-F4 on Windows.)
  • Erase local data. In the app, open Settings and use Erase all data. This clears your local posture/habit history and settings on this computer. It does not touch your account.
  • Unlink this device. On the website, open your Account page and remove the device under Devices. The app on that computer loses its linked access, but your account and any other devices stay.
  • Delete your account. On the website Account page, under Security → Your data, use Delete my account. This removes your account and server-side records (device links, access grants, invite redemptions, any subscription rows). It cannot be undone, and it is separate from the local data on your computer — uninstall the app and erase local data if you also want nothing left on the device.

To uninstall the app itself:

  • macOS: drag ScreenGuardian from Applications to Trash.
  • Windows: use Apps & features in Settings, or the ScreenGuardian uninstaller in the Start menu.

Refunds
