Privacy Policy
How we handle information when you use MM Ruler Online.
Summary
MM Ruler Online is built to work without collecting personal information. The ruler runs in your browser. The lengths you measure are never sent to us. This policy covers the mm ruler online, the printable mm ruler and the PPI calculator.
Information Stored on Your Device
To remember your calibration, the mm ruler online saves a small setting in your browser’s local storage (your screen scale and the reference object you chose). It stays on your device, is not sent to our servers, and you can remove it by clearing your browser data or pressing Reset calibration.
