Privacy Policy

Last updated: October 28, 2026

1. What we collect

All calculators and tools on this site run locally in your browser. Data you enter into the tools is never uploaded or stored on any server.

When you use the feedback form, we store what you voluntarily submit: the feedback text, optional contact info, the referring page, and the submission time. This data is used solely to improve the site, is never sold, and is not shared with third parties.

2. Cookies and advertising

This site may display third-party advertisements (such as Google AdSense). These advertising partners may use cookies to show you more relevant ads. You can:

• Manage personalized ad preferences in Google Ad Settings (adssettings.google.com);
• Opt out of some third-party ad targeting via aboutads.info;
• Clear or disable cookies in your browser settings.

The site itself uses localStorage only to remember your language preference and similar settings — not for tracking.

3. Data storage and security

Feedback data is stored on an access-key-protected server, viewable only by the site owner. If you would like your feedback deleted, leave a note with contact info via the feedback page and we will remove it promptly.

4. Children

This site does not knowingly collect personal information from children under 14.

5. Changes to this policy

Material changes will be posted on this page with an updated date. Continued use of the site after changes constitutes acceptance of the updated policy.

6. Contact

For any privacy-related questions, reach us through the feedback page.
