Privacy policy
The short version first: Zhenku is a static information site. We do not want your account, and the tools all run inside your browser without uploading anything. The details are below.
What we do not collect
We do not ask you to register or sign in, and we do not ask for your Binance account, password, recovery phrase, or any account credential — anyone asking for these in the name of "Zhenku," at any time, is a fake. The site's tools (account security check, password-strength check, the various self-check lists, and so on) all run locally in your browser; what you type is not uploaded and is never seen or stored by us. It is gone the moment you leave the page.
The small amount of data that may be generated
- Server access logs. Like most websites, the hosting server may record routine technical details when you visit (such as IP address, browser type, and time of access), used for security and operations, not to identify you personally.
- Third-party fonts. This site loads fonts via Google Fonts, so during loading your browser makes requests to Google's servers, which Google may log under its own policy. This part is governed by Google's privacy policy.
- Local storage. The site itself does not rely on account cookies; if an individual tool uses your browser's local storage, that data stays on your device and is not sent back to us.
The referral link
If you choose to use the Binance referral link in the sign-up-and-harden guide, attribution is handled on Binance's side. We may earn a commission, but we receive none of your account information. See the disclaimer and the about page for more.
Your rights
Before permission, or after refusal, this analytics code is not loaded. Your choice is stored in this browser for 180 days; analytics cookies are configured to last at most 180 days. Analytics settings lets you change your choice. Withdrawal reloads the page, clears this domain's GA cookies and stops future measurement; it does not automatically delete previously sent data. Refusal or withdrawal does not restrict reading or tools. Google may process data on servers outside your region. Use the contact details on this page for data-related requests.
Updates to this policy
This policy may be updated as the site changes; once updated, the current version on this page applies.

It processes page views, visit times, browser and device information, referring pages and enabled interaction events. First-party cookies distinguish visits; network requests also send necessary technical information to Google. We do not supply names, email addresses, account details or tool inputs, and do not use these statistics for ad personalization or cross-site account linking.
