Privacy Policy
Last updated: 2026-06-10
What we collect
- Wallet address (when you sign in with Ethereum) — stored as your account identifier.
- Email address (when you sign in via magic-link) — stored as your account identifier.
- Session metadata (IP, user agent) — stored alongside session tokens for security audit.
- Saved rankings — your private and (optionally) public ranking configurations.
- Audit log — every authentication and sensitive action is recorded for 2 years.
Analytics
- We use Google Analytics 4 to count visits, in consent-default-denied mode: until you accept the analytics banner, GA runs cookieless (aggregate, modeled counts only) and sets no analytics cookie. Accepting sets one first-party analytics cookie; you can decline and everything works the same.
- No advertising pixels, no ad networks, no cross-site cookies for advertising.
- We never sell or share usage data for advertising purposes.
Public on-chain data
Polyrank surfaces public Polygon blockchain data. We do not own or control on-chain data, and we cannot remove it from the blockchain. The wallet → display-name and wallet → P&L associations we publish are derived from public sources (the blockchain and Polymarket's public Data API).
Where data is stored
Polyrank runs on Hetzner servers in Germany. Backups are stored at Backblaze B2 (US). We do not transfer your data to third parties for commercial purposes.
Your rights
You can delete your account at any time — this removes your auth account, saved rankings, and session history. We cannot delete on-chain trade data associated with your wallet (it's on the blockchain). Email [email protected] for deletion requests.
