Privacy Policy

The short version: your data never leaves your browser. Numvella performs every calculation locally on your device. The numbers you type are not sent to a server, not logged, and not stored by us.

What we collect

We collect no personal data from your calculations. To understand overall traffic and performance, we use privacy-friendly, cookieless analytics that measure aggregate page views and loading speed. These do not use tracking cookies and never receive the contents of your inputs.

Cookies

Numvella does not set tracking cookies. If we introduce advertising in the future, we will update this policy and request consent where required by law (GDPR/ePrivacy) before any non-essential cookies are set.

Saved on your device

To save you re-typing, calculators remember your last inputs in your browser's local storageand restore them on your next visit. This data stays on your device, is never uploaded to us, and you can remove it any time by clearing your browser's site data.

Your shareable links

Some calculators also encode your inputs into the page URL so you can share a result. That information lives only in the link you choose to share — it is never sent to us.
