Privacy policy

Short version: this site doesn't ask you to sign up, doesn't want your personal information, and runs every tool right in your own browser. Last updated: June 20, 2026.

What we don't collect

We require no sign-up and don't ask for your name, email, phone, ID documents or any wallet information. Every calculator on this site (fees, exchange rates, P&L, position size and so on) runs locally in your browser — the numbers you type are never uploaded to or stored on our servers.

The limited third parties we use

• Content delivery and hosting: to make the site load faster and more reliably, we may use a CDN. The provider may log access (such as IP and browser type) as a matter of routine, for security and performance — this is normal for visiting any website.
• Fonts: page fonts may load from Google Fonts, and when they do your browser communicates with its servers.
• Market API: the ticker at the top and some tools read prices directly from Binance's public market API; that request is made by your browser, and we don't handle the data.

We run no ad tracking and sell no data. If we add site analytics in the future, we'll update this page to explain it.

Cookies

The site's own features don't rely on tracking cookies. The third-party services above may set necessary technical cookies. You can clear or block them in your browser at any time without affecting your reading.

Third-party links

This site contains links to third parties such as Binance (including referral links). Once you click away, how they handle your data is governed by their privacy policy, not ours — please read it yourself.

Your rights

Because we don't collect your personal data in the first place, there's usually no personal information for you to access, correct or delete. If you have any privacy questions, reach us through the contact page.
