Cookie policy. Essential only.
We keep your sign-in session and an unfinished submission in your browser. Nothing else. No ad trackers, no third-party analytics.

The short version
OptiLearn sets no advertising cookies, no analytics cookies and no third-party trackers. The only things stored in your browser are what is needed to keep you signed in and to not lose a half-finished submission. Because all of it is essential, there is no cookie banner.

Privy entries exist only if you sign in. If you paste an address instead, nothing about your wallet is stored in your browser.
Privy
Sign-in is provided by Privy. When you create a wallet with email, Privy runs it inside a secured frame served from its own domain and stores what it needs there, which OptiLearn cannot read. Privy's own policies apply to that storage; see privy.io.
What we do not use
- No advertising or retargeting pixels.
- No third-party analytics, heatmaps or session recording.
- No fingerprinting. The only network identifier we keep is a salted hash of your IP, stored on our server for rate limiting, not in your browser.
Your choices
You can clear or block cookies and site data in your browser settings at any time. Clearing them signs you out and discards any unfinished submission; it does not affect submissions you already sent or rewards you received. Signing out from the wallet menu removes the Privy session too. You can check all of this in your browser's developer tools: the site only talks to its own servers and /api routes, file storage when you upload, Privy for sign-in, and public blockchain services.
Changes
If we ever add a non-essential cookie, we will ask for your consent first and update this page before it goes live.
