Privacy Policy

Last updated: October 4, 2026

This site (AI Compute Value Chain Market Cap Rankings) respects and protects your privacy. This policy explains what information we collect and how we use and protect it.

1. Information We Collect

• Account information: the email address you provide at registration, and your password after encryption (salted PBKDF2 hash — we never store plaintext passwords).
• Watchlist data: the list of companies you choose to follow. While you are signed out it is kept only in your own browser (localStorage) and is not uploaded to our servers.
• Technical information: for security purposes (protection against brute-force attacks and automated registrations), the server temporarily records IP addresses and request rates.

2. Information We Do Not Collect

• We do not collect phone numbers, real names, identity documents or other personally identifying information;
• We do not use third-party advertising or user-behaviour tracking SDKs;
• We do not sell or share your personal information with any third party.

3. Data Storage

Account data is stored in the Cloudflare D1 cloud database provided by Cloudflare, Inc., in Cloudflare data centres located outside mainland China. Access to the database is limited to the site's operators, and passwords cannot be reversed.

4. Your Rights

• You may sign out and clear browser-local data at any time;
• To delete your account and all associated cloud data, email the site operator. We will handle the request within 7 business days.

5. Cookies

The site uses a single session cookie to keep you signed in (HttpOnly, Secure, SameSite). It is not used for advertising or cross-site tracking. Refusing cookies affects only the sign-in feature; browsing and data look-ups are unaffected.

6. Changes to This Policy

If this policy changes materially, we will update this page and note the date.
