Privacy

The short version

• Your notes, slides, and recordings live in your own Notebook. We do not sell them.
• We only use your materials to run the features you asked for — search, cited answers, and your deadline tracker.
• Recordings capture other people's voices. Getting consent to record is your call, under your school's rules. We say this plainly in onboarding.
• You can mark any file "don't index" so we never read it into your Notebook.
• When you delete your account, we destroy your encryption key. Without the key your data is permanently unreadable — real destruction, not a soft-delete flag.

What we collect

We collect the materials you give us — notes, slides, photos, documents, and lecture recordings — and the account details we need to sign you in, such as your email. We also keep an activity log of what the agent did on your behalf so you can see and undo its work.

How we use it

We use your materials to build your searchable Notebook, answer your questions with citations back to your own sources, and keep your course tracker up to date. We do not use your content to train shared models, and we do not share it with other users.

Voice and recordings

Lecture recordings involve other people's voices — usually your instructor and classmates. We treat a recording as your own captured study material. We store the audio in your tenant only, and we never use voice data for anything beyond your Notebook.

Consent to record is your responsibility, under the rules of your institution and the laws where you study. We state this plainly during onboarding rather than burying it, and you can exclude any recording from indexing at any time.

Where your data lives

Your content stays in your own tenant. We keep tenants apart at the database level, and we back that boundary with a separate encryption key for each tenant. Logical separation and cryptographic separation both hold at once. You can export your whole Notebook as plain Markdown — the same files open in Obsidian — at any time, so your knowledge is never locked in.

Deleting your data

When you delete your account, we destroy the encryption key for your tenant. Because your data is encrypted with that key, destroying it makes the data permanently unreadable — this is called crypto-shredding. That's real destruction, not a soft-delete you have to take on faith.
