Privacy Policy

Last updated August 16, 2026. The short version: we collect very little, we sell none of it, and you can delete all of it by sending one email.

What we collect

If you create an account, we collect your email address and a password. That's what lets you sign in.

As you use the site, we keep the companies you save in My Burrow and, if you're logged in when you play, your "Is it PE?" quiz scores. Both exist so your profile works; neither is used for anything else.

We also see basic, anonymous usage data through Vercel Analytics: things like which pages get visited and roughly how many people visit them. This data is cookieless and is never tied to you personally.

What we never do

We don't sell your data. Not to advertisers, not to data brokers, not to anyone.

We don't share it with third parties, with one narrow exception: the services that physically run Ferret. Our database runs on Supabase and our hosting runs on Vercel, so your data passes through their infrastructure the same way a letter passes through the post office. They don't get to use it for their own purposes.

How long we keep it

We keep your data for as long as your account is active.

If you delete your account, your data is permanently deleted. To delete your account, or to ask us to correct something we have about you, email [email protected] and we'll take care of it.

Where it lives and who can see it

Your data is stored via Supabase and hosted via Vercel. Only Ferret has access to your personal data; no other party can read it.

If Ferret ever shuts down

We'll notify users by email with 30 days' notice. During that window, you can email [email protected] to request a copy of your data. After the 30 days, all personal data is permanently deleted.

Cookies

We use no tracking cookies. Our analytics (Vercel Analytics) are cookieless, which is why you've never seen a cookie banner here.

Browser extension

The Ferret browser extension reads the web address and title of your active tab so it can look up whether that company is tracked on Ferret. It doesn't read page content, keystrokes, or your browsing history beyond the tab you have open.

Signing in to the extension uses your existing Ferret account. Your session is stored locally in the extension and is only ever sent to letsferret.com. Saving a company or requesting research from the extension writes to your account the same way it would on the website, under the same rules described above.

Uninstalling the extension removes that local session immediately; it doesn't change anything else about your account.
