What we store
- Usage events. When you browse the observatory we record the page path, the record you opened (a tool, a study, a country), the interface language and a daily rotating hash computed from your network address and browser signature. The hash lets us count distinct visitors for a day; it cannot be reversed and changes every day. We honour the Do Not Track and Global Privacy Control signals.
- Assistant questions. Questions asked to the assistant and the answers given are stored so that curators can see what the observatory fails to answer. Do not include personal information in a question.
- Contributions. A contribution stores what you typed: the proposal itself and, if you provided them, your name, e-mail address and organisation, so that a curator can come back to you. Approved study proposals become public records; your contact details never do.
- Accounts. If you create an account we store your e-mail address, a password hash (argon2) or the fact that you sign in by e-mail link, your name and organisation, and your sessions.
