Privacy policy

Sipculator is built to know as little about you as possible. Last updated 29 October 2026.

The numbers you enter

Every calculation runs in your browser. The amounts, rates and timelines you enter are not sent to us or stored on a server. When you change them, they are written into the page address so that a reload or a copied link keeps your plan; anyone you share that link with can see those numbers.

What is stored on your device

If you switch between the light and dark themes, your choice is saved in your browser’s local storage so the site remembers it. The site stores nothing else itself.

Analytics

We use Google Analytics to count visits and see which pages are used. It is set up to report the page address without the part that holds your plan’s numbers. Google Analytics uses cookies and processes data such as your device type and approximate location under Google’s privacy policy. You can opt out with Google’s opt-out browser add-on.

Hosting

The site is served by Cloudflare, which processes technical data such as IP addresses to deliver the pages and to protect the site from abuse.

Changes

If this policy changes, the date at the top of the page will change with it.
