Data retention

Answer in brief

How long a vendor keeps your prompts, uploads and outputs, and when it deletes them.

What it means

Data retention is the length of time a vendor stores what you send it. That includes prompts, uploaded files, search history and generated reports. Retention can depend on the plan, the settings you choose and the law where the data is held. A short retention period lowers risk, but it can also limit features such as chat history and saved projects.

Before you upload client documents or unpublished research, read the vendor's privacy and retention policy. Look for how long chats are kept, whether deleted items are removed from backups, and whether team admins can set retention rules. If you cannot find the answer in the policy, ask the vendor in writing before you upload anything sensitive. Keep a dated copy of the policy you checked, since vendors update these pages.
