We are not in the data business
We do not sell, rent, share, or mine your information. There are no ads, no tracking pixels, and no third-party advertising networks.
What we store
The only personal detail we need is the email address you sign up with, so you can log in and have a profile. Anything else on your profile (a display name, handle, bio, or payment links such as a Lightning or Bitcoin address) is there only because you chose to add it. Your notes, conversations, and library are saved so the app works for you across sessions and devices.
AI features
When you use the AI reading companion, the relevant text from your conversation is sent to a third-party AI provider to generate a response. That is the only reason your text leaves our systems.
Published documents are permanent
Once a document is timestamped on the Bitcoin blockchain it cannot be edited or deleted by anyone, including us. That permanence is the point of the platform.
You are in control
From your settings you can export everything we hold about you as a single file, or delete your account at any time. Deleting removes your profile, notes, conversations, and library. Published documents remain (they are permanent), but your authorship is anonymized.
Where it runs
The app runs on Vercel, with data stored in a Neon Postgres database.
