What we don’t collect

No account, no ads, no tracking cookies. The numbers you type into the calculator are processed in your browser and are not sent to us. Your variation table is saved in your browser’s local storage only; clear it by clearing site data.

Analytics

We use Cloudflare Web Analytics, which counts page views without cookies and without building a profile of you. Like any website, our host (Cloudflare) processes IP addresses to deliver pages and protect against abuse.

Waitlist

If you join the waitlist we store your email, the plan you picked, an optional ship-from country, the page, the date, your country as detected by Cloudflare and your browser’s user-agent, in a Cloudflare D1 database. We use it only to email you when paid plans open. To limit abuse we keep a hashed (not reversible) form of your IP address for 24 hours. To be removed, reply to that email or contact us through the site, and we will delete your entry.

Sharing

We don’t sell or share your data. Cloudflare hosts the site and database as our processor.
