Key facts
- Brave’s sharing conversations with AI help page says that follow-up questions are handled by Ask Brave as of 25 September 2025.
- Brave stores private conversation state for the duration of the conversation and automatically erases it after 24 hours of inactivity.
- A conversation that a user makes publicly available is stored for up to 7 days.
- Brave says the conversation is encrypted, with the encryption key stored locally on the user’s device, and says it does not retain the user’s IP address.
- In its Ask Brave announcement, published 29 September 2025, Brave describes chats as encrypted and ephemeral and says they expire by default after 24 hours of inactivity.
What is the retention period for a shared chat?
The documented answer is up to 7 days. Brave’s sharing conversations with AI help page describes the event that activates this rule: the user chooses to share a conversation by making it publicly available. The page states a maximum period, so the wording does not establish that every public link remains available for the full seven days.
The page describes this public-sharing window alongside a separate rule for ordinary conversation state. A shared chat therefore has a public availability period that is distinct from the 24-hour inactivity rule for a private chat.
What happens to an inactive private chat?
Ask Brave must store conversation state on Brave’s servers while the conversation is active. Brave’s sharing conversations with AI help page says that state is automatically erased after 24 hours of inactivity. The same page says the conversation is encrypted and that its encryption key is stored locally on the device.
Brave’s 29 September 2025 product announcement uses the same default interval and describes chats as ephemeral. It also says that questions and conversations are never used for training. This announcement supports the 24-hour rule for private chat state, while the help page supplies the separate public-sharing maximum.
Which retention layers does Brave describe?
Brave’s Search privacy notice identifies Ask Brave as a service that provides a concise summary with source references. It repeats the 24-hour inactivity rule and the public conversation period of up to 7 days.
The notice also describes a provider processing layer. It says Brave enables Zero Data Retention for Nebius Token Factory, meaning that user prompts and responses are never stored after the request is processed. That statement concerns request processing by the named provider; Brave’s conversation-state rule separately describes how long the chat state is kept for the service.
The privacy notice says Brave temporarily processes IP addresses for service integrity and deletes them within seconds. This is a separate retention statement from the two conversation windows.
What should a reader quote?
For a public shared link, quote Brave’s documented maximum: up to 7 days. For a private chat, quote the inactivity condition: automatic erasure after 24 hours without activity. For a provider request, the privacy notice says prompts and responses are never stored after processing under Zero Data Retention.
