What we store

Online Ruler saves your calibration setting (screen PPI) and your light/dark theme preference in your browser's local storage. This data stays on your device — it is not sent to our servers, and we don't have access to it.

What we don't do

We don't require an account, don't collect personal information, and don't sell or share data with third parties.

Standard server logs

Like most websites, our hosting provider may keep basic technical logs (such as IP address and browser type) for security and performance purposes. These are not used to identify individual visitors for marketing purposes.

Changes to this policy

This policy may be updated from time to time. Continued use of the tool after changes constitutes acceptance of the updated policy.
