Privacy and cookies

We do not use cookies.

Calculator queries are processed on the spot and are not linked to any identity. Analytics are first-party and cookie-less: we do not store your IP address or your browser. To count unique visitors we derive a code using a random key that changes daily and is destroyed after 60 days, so it is neither reversible nor able to follow you from one day to the next; we keep only per-page aggregates. There are no third parties and no data transfers. If you subscribe to the API, billing data is handled by our payment provider (Polar Software Inc.) as merchant of record; we store only your email address and your API key.
