Privacy Policy

Last updated: July 2026

The short version

Every calculator on revenuemarkr runs entirely in your browser. The numbers you enter are processed locally on your device and are never uploaded, logged or stored by us. There are no accounts and no forms asking for personal data.

What we don't collect

• Your calculator inputs or results — these exist only in your browser tab (and in the page URL if you choose to share a link).
• Names, emails, or any personal identifiers — we never ask for them.

Shareable links

When you use “Copy link”, your inputs are encoded into the URL itself. That URL exists only where you paste it — we don't receive or store it. Don't share links containing numbers you consider confidential.

Analytics & advertising

We may use privacy-respecting, aggregate analytics to understand which calculators are used, and we may show advertising to keep the tools free. Ad providers may use cookies subject to their own policies; where required, you will be shown a consent choice first.

Local storage

We store one preference in your browser's local storage: your light/dark theme choice. That's it.
