What this site collects, and what it doesn't

No accounts, no identity details

Dingtouma is a plain static site with no login, no sign-up and no accounts. The site doesn't ask for your phone number, email or any identity details, and there's nowhere on it to enter them. Reading the notes and using the calculators requires no registration.

Analytics and cookies

To understand roughly how many people visit and which content they use, this site has enabled Google Analytics 4 (GA4). GA4 uses cookies to collect page visits and interactions, device and browser type, referral source, and approximate region. Google processes that data under its own privacy policy. We use the reports to understand aggregate trends and do not try to identify individual visitors. If you would rather not take part in analytics, you can manage or disable cookies in your browser or use a content blocker to block the analytics script; the content remains readable.

The site is also served through Cloudflare, and Cloudflare puts its own small Web Analytics script on each page (it loads from static.cloudflareinsights.com). That one is basically a headcount: how many visits, which page people came from, how fast pages loaded. On its Web Analytics page, Cloudflare says the script doesn't drop cookies or write to localStorage, and it doesn't try to work out who you are from your IP address or which browser you're on. Whatever blocker you run for GA4 will catch this one too.

We don't sell your data

We do not sell, trade or commercially repurpose data obtained through visit analytics. The site also has no accounts or forms and does not ask you to submit a phone number, email address or other identity details.

Fonts load from Google Fonts

Page fonts load through Google Fonts. Your browser requests styles and font files from fonts.googleapis.com and fonts.gstatic.com. Google receives connection information needed for those requests, such as your IP address and browser details, and handles it under its privacy policy.

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.
