YARROW is built on a simple privacy principle: collect as close to nothing as the product allows. There are no accounts with emails, no passwords, no names, no tracking pixels, and no sale of data — ever.
1What we store
When you sign in with a wallet we store: your public wallet address, the time you first signed in, and the time you were last seen. If you use portal features we store the data those features need: your watchlist symbols and your practice positions (symbol, side, quantity, entry/close price, timestamps). That is the complete list.
2What we do not collect
We do not collect names, emails, phone numbers, government identifiers, precise location, contacts, or biometric data. We do not read your wallet's balances or other activity beyond the address you sign in with. We do not use third-party analytics, advertising trackers, or fingerprinting.
3Cookies
We set only functional, httpOnly cookies: a short-lived sign-in nonce and a session token proving your wallet signature. They contain no tracking identifiers and expire automatically. There are no advertising or third-party cookies, so there is no cookie banner theater.
4Server logs and security
Like every web service, our infrastructure may briefly process IP addresses and request metadata to serve responses, enforce rate limits, and defend against abuse. Persistent application data lives in a managed Postgres database, encrypted in transit. Public blockchain data (such as your address's on-chain activity) is by nature public and outside any privacy policy's control.
5Sharing
We do not sell, rent, or trade data. We share data only with the infrastructure processors required to run the Platform (hosting and database providers) or when the law compels us.
6Your rights
Because everything we hold is keyed to your wallet address, you can request deletion of your watchlist, positions, and user record at any time through the project's public repository. Depending on your jurisdiction (GDPR, CCPA, and similar), you may have additional rights of access, correction, portability, and erasure — we honor them regardless of where you live.
7Changes
Updates to this policy are posted on this page with a revised date. Material reductions in your privacy will never be applied retroactively to data collected under an earlier policy.
