Privacy notice

Your account: the email address and a hash of the password.
Your saved graphs: the papers, their positions and colours, your notes, and the chat (your messages, the model's answers, the tool calls). While the site is in test, its author reads the chats to find bugs.
Your usage: the tokens and cost of each model call, per month, for the allowance.
What is typed in the front page's bar while logged out, with the branch the page took (graph, search or login message), kept for a month to review that rule.

Your chat messages, a summary of the graph (paper titles) and, when you ask for analyses, paper titles and abstracts are sent to Anthropic, which runs the model.
Your browser fetches paper data from the citation database, and abstracts and author lists from OpenAlex and Crossref directly.

Two cookies only: the session cookie, which keeps you logged in, and the CSRF cookie, which protects the forms. No tracking.

Deleting your account removes it with its graphs, chats and usage records at once. Nightly database backups are kept 30 days.
