Yes, for preparing the copies: processing happens on your computer, and no third party receives your documents. What you then give to an AI, and to which one, remains your decision: only the reviewed and approved copy is meant for that.

Its practical guide “La déontologie et l'intelligence artificielle” (Ethics and artificial intelligence), adopted in March 2026 (1st edition, April 2026), recommends systematically pseudonymizing or anonymizing data before any use of a generative AI. It also points out that this does not suit every task, and that the risk of re-identification needs watching. The CNB guide, point by point.

Yes, provided professional secrecy is respected, and it covers every document in the file. That's why the CNB guide (April 2026) recommends systematically pseudonymizing or anonymizing data before any use of a generative AI. ChatGPT and professional secrecy: the method.

The parties, fellow lawyers, witnesses, their addresses, e-mails, phone numbers and IBANs are detected automatically. During review, check what can still identify the case: docket number, court, hearing dates, and amounts, which are masked with one click.

Yes: the same person keeps the same label throughout the file, and variants of a name (“Ms Durand”, “Camille Durand”) are matched when there is no ambiguity. During review, you can rename a label, for instance [PERSONNE_CLIENTE]. Anonymizing a court decision.

Yes, if an indirect detail remains visible: a docket number, a hearing date, a property address, the name of a very local court. That's why each document is reviewed side by side before export, and one click masks whatever detection missed.

Not systematically. The CNB guide (April 2026) puts it this way: it is up to the lawyer to decide whether to inform the client about the use of AI tools (p. 34). There are two exceptions: a client who asks the lawyer about their practices must be informed, and consent is required if the client's data is used to train an AI internal to the firm. The guide's model clause for the fee agreement rules out passing any confidential information to a tool without sufficient guarantees (p. 35). Informing the client, the team and the judge.

Yes, pseudonymized like your own documents: they name your client, and the CNB guide excludes from any query a file containing the client's name (p. 15). It adds a check for these documents, whose rights the lawyer does not hold: the AI's terms of use must not allow the provider to appropriate or reuse what it is given (p. 29). Drop them in with the rest of the file: the same name gets the same label as in your own pleadings.

Yes, but the lawyer remains responsible. The lawyer must make staff and anyone working with them respect secrecy, and the RIN (art. 2.3) adds that the lawyer answers for any breach of secrecy they commit. The CNB guide recommends an AI use policy (p. 36). In AnonymFiles, nothing is exported without document-by-document approval: a simple rule to write into it. Pricing is per seat: €290 excl. VAT per year, €240 excl. VAT from 3 seats.

They are covered by secrecy “whatever the medium”, electronic included (RIN, art. 2.2), except correspondence between lawyers marked as official. AnonymFiles reads .eml and .msg e-mail files: subject, sender, recipients, date and body are redacted in a text copy, signature included; attachments are not copied, so drop them in as file documents.
