Privacy

The short version

We don't store or send the names, dates or numbers you enter. Every calculation happens in your own browser.

What your browser keeps

Your theme choice (light or dark) and, if you use a date-based calculator, your birth profile (first name and birth date), so other calculators can fill them in. Both stay in your browser's local storage. Use "Forget me" on the home page, or clear your browser data, to delete them. Phone numbers are never kept.

Shareable links

The gematria calculator puts your word in the page address so you can share it. Anyone you send the link to can see that word. The gematria page also loads a list of common English words from this site to find matches; nothing about you is sent.

Contact form and statistics

If you write to us, we store your message, its type, your optional rating and the language, for up to 12 months. We never ask for or store a name, e-mail or IP address. Cloudflare Turnstile checks that a human is sending the form, and messages in other languages are translated to English with Cloudflare Workers AI. We also count anonymous daily totals, such as how often each calculator is used or shared, with no personal data.

Cookies

We don't set any cookies of our own, and our visitor statistics are cookieless. When ads are shown, Google and its partners may use cookies or similar identifiers (see Advertising).

Advertising
