Privacy Policy

Overview

Maßband Online ("we", "our", "the service") is committed to protecting your privacy. This policy explains what information we collect, how we use it, and your rights. The short version: we collect almost nothing and we do not sell or share your data.

1. Information We Collect

We do not require you to create an account or provide any personal information to use Maßband Online.

The ruler tool runs entirely in your browser. Any calibration data (your screen PPI, chosen calibration method, theme preference) is stored only in your browser's localStorage and never transmitted to our servers.

We may collect the following non-personal, aggregated data through standard server logs and security analytics:

• Pages visited and approximate session duration
• Browser type and operating system (aggregated)
• Referring website or search engine
• Country-level geographic region (not precise location)

2. Cookies

Maßband Online does not use advertising cookies or third-party tracking cookies. We use localStorage (not cookies) to remember your calibration, units, and theme preference between visits. This data never leaves your device.

You can clear this data at any time by clearing your browser's site data or clicking reset inside the calibration settings.

3. Google Fonts

We use Google Fonts to load the Inter and JetBrains Mono typefaces. When your browser downloads these fonts, Google may log your IP address as part of standard font delivery. Please refer to Google's Privacy Policy for details.

We do not embed social media widgets, advertising networks, or any other third-party trackers.

4. Data Retention

We do not store personal data on our servers. Server access logs, if retained, are kept for no longer than 90 days and are used solely to diagnose technical issues and ensure server security.

5. Children's Privacy

Maßband Online is a general-purpose utility tool suitable for all ages. We do not knowingly collect any personal information from children under 13. Since we collect no personal information from any user, this service complies with COPPA and European privacy standards by design.

6. Your Rights

Because we do not collect identifiable personal data, there is typically nothing for us to retrieve, correct, or delete on your behalf. If you have concerns, please contact us and we will respond promptly.

If you are located in the European Economic Area (EEA), you have the right under GDPR to access, rectify, or erase any personal data we hold, and to lodge a complaint with your local supervisory authority.

7. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the service after changes are posted constitutes acceptance of the revised policy.
