AngleSnap is a browser extension by WristSkill Labs LLC. It measures angles on images and videos you choose to measure in your browser. This policy explains what data the extension handles.

What we collect

Nothing. AngleSnap does not collect, transmit, or store personal data on any server.

• No accounts: You do not sign in to use AngleSnap.
• No cloud storage: Measurement points and angles exist only in memory while the tool is active on a page. They are cleared when you turn the tool off or refresh the page.
• No analytics: We do not run our own analytics or tracking.

What runs on your device

When you click the AngleSnap icon, the extension draws an overlay on the current tab so you can place three points and read an angle. All geometry is calculated locally in your browser. Copied angle values go only to your system clipboard when you tap Copy.

Permissions

• activeTab: AngleSnap can interact with the tab you are viewing only after you click the extension icon.
• Content script: A small script is loaded on web pages so the tool can respond when you activate it. It does not draw overlays, read page content, or send data anywhere until you click the icon.

Clinical disclaimer

AngleSnap provides geometric angle readings for convenience. It is not a medical device and is not validated for clinical range-of-motion measurement. Clinicians and patients are responsible for how they interpret and use any reading.
