What we store, and what we do not

A paper you upload stays private to your own workspace. It is not added to the public library, and it is not shown to other readers, unless its licence permits republication and you publish it yourself.

The public library contains open-access and CC-licensed work only.

If you create an account we store your username, display name, bio, and the answers you gave during onboarding. Onboarding answers are visible only to you and are used to decide what your home page surfaces first.

The guest demo account stores nothing. Everything it shows is generated, and nothing you do inside it is written anywhere.

Pepiros calls Semantic Scholar to populate the related-papers rail and OpenAlex to expand a citation graph. Both receive the identifier of the paper being looked up. Neither receives your account details.

Grounded chat sends the text of your question and the relevant source excerpts to a language-model provider. It does not send your identity.

There is no third-party analytics or advertising script on this site. The reach figures on your own dashboard are counted server-side and are visible only to you.

Privacy questions go to the same place as everything else: open an issue on the repository, or use the security contact for anything sensitive.
