What we don't collect from you

This is a static site

Dingtouma is a plain static site — no login, no sign-up, no accounts. I don't ask for your phone number, email or any identity details, and there's nowhere on the site to enter them. You come to read the notes and use the calculators, and you can leave whenever you like; I don't end up holding a file on you because of it.

Analytics and cookies

To get a rough sense of how many people visit and which pages they read, I may use some web analytics tools (Google Analytics, for instance). They use anonymous cookies for rough counts, and what they show is aggregate data like "how many visits, from roughly which regions" — not "who you are." If that bothers you, you can switch off cookies or use private mode in your browser settings; it won't stop you reading the content normally.

We don't sell your data

I have no personal data of yours to sell, and I will never sell, trade or repurpose it. This one needs no long explanation — it just doesn't happen.

Links that lead off the site

There are links here that go to Binance. Once you click out, you've entered their site, you're under Binance's own privacy policy, and it's no longer to do with this site. How they handle your information is governed by their rules; I'd suggest reading theirs too before you register.

This page is kept deliberately lean and broadly in keeping with the spirit of the GDPR. Questions? Write in: [email protected].
