Information generated automatically

• Session cookie: one essential session cookie is used for anti-forgery checks when you submit a form. It expires when you close your browser and is not used for tracking.
• Abuse prevention records: to limit malicious repeat submissions, we store a cryptographically hashed network identifier (which cannot be turned back into an IP address) for up to 24 hours.
• Analytics: if this site has analytics enabled (such as Baidu Tongji), the analytics service records page visits under its own rules, to help us understand which content is useful.
• Local preferences: the homepage’s “Find your place” remembers your last selected cell in your browser. It is not sent to this site.

Where it’s stored and who can see it

Submitted information is stored in a database on this site’s server, outside the public web directory, and is never displayed publicly. Only Liu Jinlong himself can view it, through a password-protected admin panel.

To reply promptly, a summary of each new submission (name, contact details, summary of your request) is sent to Liu Jinlong’s own WeChat via a WeChat push service (such as PushPlus). The push service is provided by a third party, and pushed content is subject to its terms of service.

Admin login is protected by a password and two-factor authentication, and every login and sensitive action is logged. The database is backed up automatically once a day; backups are also stored outside the public web directory, and only recent copies are kept.

This site does not sell your information, does not send it to external AI models, and does not share it with any other third party, except where required by law.

How long it’s kept

Leads that don’t turn into a collaboration are deleted automatically once 12 months have passed since submission with no further communication. If we work together or you join the Token Diggers Union, necessary records are kept as the collaboration and the law require. You can also ask for earlier deletion at any time.

Your rights

You can access, correct or delete the information you submitted, or withdraw your consent, at any time. How: add WeChat 486097 and give your name and the contact details you submitted with (a reference number helps). Requests are usually handled within 3 business days.

Changes

If this notice changes materially, we’ll update this page and the effective date.
