Effective September 27, 2026
The short version
When you make an account, we save your email address so you can sign in. If you sign in with Google, Google also gives us your name and profile picture, and we save those too. We never see your Google password.
Once you're signed in, we save your searches and the passages each one found, the passages you bookmark, any notes you write on them, where you stopped reading, and your settings. That's how your history and saved passages work. All of it is attached to your account.
You can try a few searches before making an account. Those are saved under a random code in your browser, not under a name. If you sign up later, we move them into your account.
If you send us feedback, we keep what you wrote.
We count things like how many searches run each day. Those counts aren't tied to your account, and they never include the words you typed. We don't record your screen.
Every website sees your IP address when you load a page, and so do the companies that host and measure ours. We use it to cap free trial searches and block feedback spam. For that we store a one-way hash of it, which can't be turned back into the address.
One cookie keeps you signed in and another remembers light or dark mode. Your browser also holds your trial code, passages you saved before signing up, and reader settings like font and line spacing. PostHog, our analytics tool, sets its own cookie so a returning visitor isn't counted twice. We don't use ad cookies.
TheoCorpus runs on Supabase, Vercel, OpenAI, Railway, Qdrant, Anthropic, PostHog, and Cohere. Some of them handle the text of your searches, because that's how we find matching passages. We send them the search text only, never your name or email address.
You can delete any search from your history, and remove any saved passage, whenever you want. To delete your whole account, or to find out what we hold about you, send a note through the feedback form with your account's email address and we'll handle it.
If this policy changes, we'll update this page and the date at the top.
