Sharing privacy

Using the calculator does not save your figures on our servers. Sharing saves your inputs, results, date, and calculation details. Anyone with the link can view and share them.

Sharing also sets a one-year cookie with a random browser ID. We keep this ID private to group saved results and may use it for future features such as rankings. Clearing cookies does not delete saved results.

Cloudflare provides hosting, storage, and security. Network addresses help limit abuse but are not included in saved result records.

Saved results remain until the site operator removes them. There is no self-service deletion option yet. Copies saved by other people cannot be recalled.
