Lexis+ with Protégé

Lexis+ with Protégé (formerly Lexis+ AI), Protégé Legal AI. Your firm, school, legal department, or government office buys a Lexis+ with Protégé subscription. Lexis+ AI was renamed Lexis+ with Protégé in February 2026, so former Lexis+ AI users are on this plan. Price: Custom quote; LexisNexis publishes no prices.

Settings that lower the risk

1. Personalization settingsWhat it does: LexisNexis says users can adjust the level of personalization or opt out entirely. It says customers decide whether personalization is enabled.
2. Opt-out of AI failover (General Terms §4.6)What it does: If LexisNexis's cloud provider fails, LexisNexis may move AI processing to a backup location, which may be in another country. The firm can opt out by giving 30 days' written notice. A firm that opts out waives claims for the resulting loss of service.
3. Protégé BYOK (Bring Your Own Key)What it does: Enterprise and government customers can encrypt stored data with keys held in their own key management service. LexisNexis says the customer can revoke access when required.
4. Administrator controls for user access and tasksWhat it does: An older LexisNexis document (2023, revised November 2024, Australian site) says administrators can limit which users have the AI. It says they can also switch off document upload and drafting for the whole firm.

Worth knowing

• The contract's no-training promise covers large language models. The product page says LexisNexis removes identifying details from AI interactions to improve performance. The contract does not rule that use out.
• Vaults are kept until someone deletes them.
• Unless the firm opts out by 30 days' written notice, AI processing may fail over to a backup location in another country.
• The Lexis terms restrict putting Lexis research into outside AI tools. Only tools with zero data retention and a no-training promise qualify.

What the policy says

Your data, in plain English

How long it is kept

• LexisNexis says conversations are deleted automatically after 90 days.
• This comes from its French-edition help page (July 29, 2026) and older U.S. and Australian documents.
• The current U.S. product page gives no period for conversations.
• Up to 10 documents uploaded without saving to a Vault are purged at the end of each session.
• Vaults are kept until the user deletes them.

• The terms do not require it to.
• Under the DPA, the customer can ask for personal data to be returned or deleted.

What happens after you delete

LexisNexis's help page (French edition) says a deleted conversation cannot be recovered. The General Terms say each user controls prompt history and its deletion. That control is subject to LexisNexis's automatic deletion controls, retention schedules, and applicable law. LexisNexis does not say how fast deleted data leaves its servers and backups. A delete-all option is not documented.

Copies kept anyway

• The General Terms make a user's deletion subject to LexisNexis retention schedules and applicable law. LexisNexis does not publish those schedules.
• LexisNexis says on its trust center that its model providers keep no prompts, under a zero-retention contract. This is not in the contract.

Temporary chat
