Privacy

Last updated 6 October 2026.

Polywatcher shows trading activity on Polymarket Perps from the venue's public data. You can use the site without an account.

What we keep

  • If you join the waitlist: your email address, when you joined, how you heard about us (if you told us), and where you came from (for example a link from our Telegram). Your email is used only to keep you updated on Polywatcher. We don't sell it.
  • If you sign in with Google: your Google account ID, your email address when Google says it is verified, your plan, and when you last visited. Your session is a random token kept in your browser; we store only a fingerprint of it. We use this only to run your account.
  • Visit counts: for each day, how many visits arrived from each country and from which site or link (for example "Kenya, from TikTok: 12"). Only a country code, a site's name and a daily total, which can be 1: no address, no time of day, and no separate entry for each visit.
  • Public market data: trades, liquidations, leaderboards and wallet names come from Polymarket Perps' public data. Wallet names are the public names Polymarket shows.

What we do not do

  • No ads, no third-party tracking scripts or analytics services, and no selling or sharing of personal data. The only thing the site counts is the visit counts above, with its own small script.
  • We keep no log of your visits and never write down your IP address. The providers that host and deliver the site see addresses in order to do so, and our server counts recent requests per address in memory for about two minutes, to stop abuse; that count is never written down.

In your browser

The site keeps a few small settings in your browser: your theme and font choice, which wallets' trading styles you have looked at this month (this never leaves your browser), the link that brought you here (kept only until you close the tab, and sent to us only if you join the waitlist), and, if you sign in, your session token. We set no cookies and use no tracking or analytics services. Clearing your browser's data for polywatcher.com removes these settings.

Services we use

  • The site runs on a globally distributed cloud network. What we keep may be stored outside your country.
  • Google, only if you choose to sign in with Google: Google's sign-in script loads when you open Sign in, and Google's own privacy policy applies to it.

Your choices

Write to privacy@polywatcher.com to see, correct or delete what we hold about you, or to leave the waitlist. Signing out ends your session on our server too.

We keep an encrypted backup of the waitlist, accounts and alert settings, made each night and kept for 35 days, then removed automatically, usually within a few days. When we delete something you asked us to, it leaves the backups the same way.

Other

Polywatcher is not meant for anyone under 18. If this page changes, the date at the top changes too.
