Privacy policy.

• Your projects, sources, and notes are yours. We do not sell them, share them, or train models on them.
• Your work is stored in your account, scoped to you. Only you can see it.
• Passwords are stored only as a salted hash. Session tokens are stored only as a hash.
• No analytics, no third-party advertising trackers. The only things we count are your own usage credits.

To run the service we need to know a few things about you.

• Account info.Your email and a hashed password. That's it.
• Project data. The projects, sources, notes, and documents you create. Visible only to you.
• AI search usage. A per-account counter of search credits used, so plan limits work.
• Support correspondence. If you write to us through the contact form, we keep the message so we can pick up where we left off.

• We do not sell your data — not to advertisers, not to AI companies, not to anyone.
• We do not use your projects to train AI models. The AI search feature uses public web data; your private notes are not in the loop.
• We do not embed third-party trackers (no Google Analytics, no Facebook pixel, no Hotjar).
• We do not require a .edu email. We do not verify that you are a student. The free tier is yours either way.

We use one essential cookie to keep you logged in. That's the entire cookie banner you'd see, if we had one.

If you live somewhere with strong data laws (the EU, California, lots of other places), you have the right to:

• See what data we hold on you — ask via the contact form.
• Export all of it as a single JSON file. Settings → Data → Export.
• Delete it. Settings → Data → Delete account. The deletion is immediate and permanent.

Writium is intended for users aged 13 and up. We do not knowingly collect data on children under 13.

Privacy questions go to contact form. We answer in plain English.
