Anthropic says voice-mode transcripts are saved in chat history, and eligible Free, Pro, and Max chats may be used to improve models when the model-improvement setting is on or under certain exceptions. For mobile dictation, Anthropic says it deletes the audio after transcription and does not use the voice itself for training; the resulting text may still be eligible. Anthropic has not clearly stated in the reviewed guidance whether raw audio from full voice-mode conversations is retained or used for training.
Voice mode and dictation are treated differently
Claude’s voice mode is a two-way spoken conversation: you speak, Claude replies aloud, and you can switch between voice and text in the same conversation. Dictation instead converts your speech into text for a prompt. Anthropic’s voice-mode help page confirms that textual transcripts of voice conversations are saved in chat history.

| Input method | What Anthropic says about audio | What happens to text | What is unclear |
|---|---|---|---|
| Mobile dictation | Anthropic says the audio recording is deleted after transcription and the voice itself is not used to train models, according to its March 16, 2026 dictation privacy article. | The transcribed chat text follows the applicable retention rules and may be used for model improvement if the setting allows it. | No material uncertainty is stated about dictation audio deletion or voice-training use in that article. |
| Full voice mode | The voice-mode help page confirms saved textual transcripts but does not state whether the original audio is retained or used for training. | The transcript is part of the chat history and may be eligible for model improvement under the rules for consumer chats. | Raw-audio retention and training use are not established by the cited voice-mode guidance. |
Anthropic’s dictation guarantee should not be extended to full voice mode: the features have different descriptions, and the voice-mode guidance does not make the same statement about deletion of original audio.

For consumer Free, Pro, and Max accounts, Anthropic says chats and coding sessions may be used to improve models when the user permits model improvement, when a conversation is flagged for safety review, when the user submits feedback, or through another explicit training opt-in. The model-training policy says potentially eligible data can include the entire related conversation and associated content, custom styles, and conversation preferences. That makes a saved transcript part of an eligible chat; it does not establish a separate rule for raw voice-mode audio. See Anthropic’s consumer model-training policy.
#1 Best Overall
- Model-improvement setting on: eligible new or resumed chats may be used for future model improvement.
- Incognito chats: Anthropic says these are not used for model improvement, even when the setting is on.
- Safety flags, feedback, and opt-ins: these are separately listed possible routes for use, so turning off the general setting does not eliminate every stated exception.
This consumer policy applies to Free, Pro, and Max, including Claude Code on those accounts. Claude for Work, API access, Amazon Bedrock, Google Cloud Vertex API, Claude Gov, and Claude for Education are outside the consumer-policy update; workplace or third-party cloud users should check the applicable organization or service terms. Anthropic describes the scope in its August 28, 2025 policy announcement.
How to turn off model improvement
- Open Claude and go to Settings > Privacy.
- Turn off Help Improve our AI models.
Anthropic’s August 3, 2026 privacy-settings guidance says this stops new chats and coding sessions from being used for future model training. It does not remove content already used in a training run or from models already trained. Anthropic also says safety-flagged conversations may still be used for internal trust-and-safety purposes, such as detecting harmful content and enforcing policies.
Deletion and retention limits
Under Anthropic’s published consumer retention policy, deleting a chat removes it from backend storage within 30 days. If model improvement is allowed, data from new or resumed chats may be retained in de-identified form for up to five years in model-training pipelines. Deleting a chat prevents its use in future model training, but does not undo training already underway or remove data from models already trained. These are Anthropic’s stated policy terms, not an independent audit of data handling. Details are in its July 1, 2026 retention article.
Privacy protections and practical precautions
Anthropic says that when users allow chats or coding sessions to help improve Claude, data is de-linked from the user ID before review, access is limited to a small number of personnel involved in model training, and tools are used to filter or obfuscate sensitive data. It separately notes the safety-review exception. The company advises caution with highly sensitive material such as financial information, health records, passwords, and confidential documents.
