No accounts, no tracking scripts, no cookie of our own.
This is a static site. It has no accounts, no login, no comment form and no newsletter. Nothing you type into a calculator on this site is sent anywhere — the arithmetic runs in your browser and the page never posts it back.
| What | Why | Who holds it |
|---|---|---|
| Standard web request logs (IP, user agent, page requested) | Serving the page, and blocking abuse | Cloudflare, as the host |
| Aggregate page-view counts | Knowing which pages are read | Cloudflare, in aggregate only |
There are no advertising cookies, no analytics scripts from third parties, no tracking pixels, and no fingerprinting. The site sets no cookie of its own. Nothing on this site is sold, rented or shared with a data broker.
If you join the Telegram channel, Telegram holds your account information under its own privacy policy, not ours. We can see the member count and the messages sent to the channel. Leaving removes you.
Links to exchanges carry a referral code. Following one takes you to that exchange, which then applies its own privacy policy and its own cookies. We receive no personal information about you from them — only aggregate counts of registrations and the commission attached to them.
Because the site holds no account and no profile, there is generally nothing to export or delete. If you believe otherwise, write to the address in the footer and say what you are asking for.
