Your documents are not for AI training.

YourBrain2 reads your documents with your own API key. Two settings in your provider account keep them out of model training. Here is every click, with pictures.

Last checked 5 November 2026. Screens change from time to time; look for the same words.

1. Your API key (what YourBrain2 uses)

YourBrain2 reads your documents through the AI provider’s API with your own key. OpenAI says it does not train its models on API data unless you opt in. Make sure you did not opt in, and switch off the logs you do not need:

  1. Sign in at platform.openai.com and choose the organization and project that own your key.
  2. Go to Settings > Data controls > Sharing. Set all three options to Disabled: model feedback, evaluation and fine-tuning data, and Share inputs and outputs with OpenAI. Do not take the free daily tokens offer: it works only by sharing your data. Press Save.

OpenAI Platform: Data controls, Sharing, all three set to Disabled, then Save

  1. Open the Data retention tab. Set API call logging to Disabled. You should see “Organization updated successfully”.

Then create your API key in API keys inside that same project and paste it into YourBrain2 > Settings > AI models. Note: for safety, OpenAI may keep API data for up to 30 days to detect abuse, then deletes it. This is OpenAI’s rule, not ours.

2. ChatGPT (if you also use ChatGPT directly)

These settings are for the ChatGPT website and app. They do not change the API key above, but if you paste documents into ChatGPT yourself, set them too.

  1. Click your name or picture, then Settings.

  1. Open Data controls (or type “data control” in the settings search).
  2. Switch Improve the model for everyone to off (grey).

Screens change from time to time. If yours look different, look for the same words: Data controls, Sharing, Improve the model.

3. Other AI providers

  • Claude (Anthropic): API data is not used for training by default. Keep it that way in the Anthropic Console.
  • Google Gemini: use a paid Google Cloud project. Free-tier data may be used to improve Google’s products; that is why YourBrain2 does not accept free keys for finance.
  • DeepSeek: read DeepSeek’s privacy policy and terms before you enable it for documents. Data is processed in China.

YourBrain2 never sends your documents to us. They go only to the AI provider you choose, with your key. Read the provider’s own terms; they decide what happens there.

Set once, then forget it.

The key you create after these settings is the one you paste into YourBrain2 > Settings > AI models.
