Analytics cookies
If you accept, Google Analytics sets two cookies: one tells visitors apart so visits can be counted, and one keeps track of the current visit. Both last 13 months. Rejecting later deletes them.
How we handle browser data
- Theme preferences: We use your browser's local storage (not a cookie) strictly to remember your light or dark mode choice and your cookie choice (kept for 12 months).
- Fonts: Our fonts are served from our own server, so loading a page does not contact Google.
- Third-party tools: We use Cloudflare Turnstile to prevent spam on our feedback form. It loads only when you open the form, sets no tracking cookies, and briefly sees your IP address to work.
- Site usage: We log general calculator usage on our own servers, row counts and transaction types processed, but never store any transaction details. This uses no cookies, records no IP address, and cannot identify you.
