Privacy & Data Policy

No personal data is collected or stored

• Any numbers you enter are only used to calculate results in your browser.
• Inputs may appear in the page URL so you can bookmark or share a specific estimate, but the server does not track or save them.
• This site does not use accounts or logins.
• We use a self-hosted, privacy-first analytics tracker to count page views, approximate device types, and referrers. It does not use fingerprinting or advertising IDs.
• The analytics tracker sets a short-lived, first-party session cookie named __ast so repeat visits can be grouped into sessions. It expires after 30 minutes of inactivity.
• No analytics data is sent to third parties.

What the server does log

• Standard web server access logs (page requests, timestamps, IP addresses) for security and troubleshooting only.
• These logs are rotated automatically and are not used for profiling or advertising.

If you have questions, contact the site operator directly.
