Generative AI has become the premier coding partner, editor, and assistant. However, this productivity explosion has left security teams and privacy-conscious users anxious. Every prompt you write—whether describing a proprietary algorithm, writing an email draft about a confidential project, or debugging security keys—reaches external servers.

In this post, we'll explain how AI providers handle your history, and how to safely run an extension-based backup system without exposing your data.

How AI Giants Handle Your History

By default, the consumer versions of these tools use your prompts to train their models:

  • OpenAI (ChatGPT): Saves your chats to chat history. If you turn off history to prevent training, your conversations are still kept in their backend logs for up to 30 days before deletion to check for abuse.
  • Anthropic (Claude): Does not use consumer data from paid tiers to train models, but holds onto messages for trust and safety reviews.
  • Google (Gemini): Logs conversations under your account. Selected logs can be reviewed by human annotators to improve Google services, and these annotated logs can be retained for years.

A Secure Way to Sync and Archive

Because keeping a copy of your chat history is necessary for productivity, many users turn to third-party tools to aggregate their logs. However, this introduces a new risk: who is hosting that database?

When building Corellate, we established strict guardrails to protect your text data while keeping the user experience seamless:

  1. We Do Not Sell or Rent Your Data: Your chat content, prompt logs, and account details are never sold, rented, or shared with third-party advertisers or data brokers.
  2. No Model Training: We will never use the history you sync to train AI models.
  3. Secure Infrastructure: We store your synced data using InstantDB, which provides encrypted transit and robust data isolation. Your database records are strictly isolated, and only your authenticated account can pull messages down to your dashboard.
  4. Export and Wipe: At any point, you can download your complete catalog in Markdown or JSON and wipe your history clean from our active storage.

Best Security Practices for Prompting

To keep your workflow clean:

  • Sanitize environment variables: Avoid pasting credentials, API keys, or raw JWT strings inside your chats. Use mocked configs instead.
  • Be cautious with PII: If parsing user logs, replace actual client names and emails with dummy placeholders before pasting them to an LLM.

Convenience doesn't have to compromise safety. You can have a unified, real-time command dashboard of your entire AI history while retaining complete ownership of your data.
