Privacy Policy

ChatCache is a Chrome extension that exports ChatGPT conversations to Markdown, HTML, TXT, PDF, JSON, CSV, and PNG. Most export processing happens locally in your browser. PDF export requires a server-side rendering step. This policy describes exactly what data is processed where, what is stored, and what is not.

When you export to Markdown, HTML, TXT, JSON, CSV, or PNG, the extension reads the conversation content from the active ChatGPT tab and processes it entirely in your browser. No conversation data leaves your device for these formats.

When you export to PDF, conversation content from the active ChatGPT tab is sent to api.getchatcache.com for server-side rendering. The rendered PDF is returned to your browser for download. Conversation content is not persisted on the server after the PDF is generated and returned.

The extension stores the following data locally using the Chrome storage API:

• Export preferences (selected format, copy-to-clipboard toggle, file name prefix, etc.)
• A stable anonymous install ID used for quota enforcement and abuse prevention

No conversation content is stored by the extension after an export completes.

The PDF rendering backend retains limited data for security and quota enforcement:

• The anonymous install ID (to enforce per-install usage quotas)
• Hashed, IP-derived rate-limit and abuse-prevention records
• Token usage and security-event logs

These records are used for quota enforcement and abuse prevention and do not include conversation content.

The extension includes an optional feedback form. If you choose to submit feedback, you may provide an email address and a message. This information is sent through the support form for support purposes. See section 8 for notes on third-party infrastructure that may process this submission.

• activeTab — read conversation content from the current ChatGPT tab when you trigger an export
• scripting — inject the selection UI (checkboxes) into the ChatGPT page for selective message export
• downloads — save exported files to your device
• storage — persist your export preferences and anonymous install ID locally

Host access is limited to chatgpt.com, chat.openai.com, and api.getchatcache.com.

ChatCache does not use third-party analytics, advertising, or tracking tools. PDF rendering is handled by ChatCache infrastructure. If you choose to submit feedback through the support form, that submission may be processed by third-party form infrastructure.

If you have questions about this policy, use the support or contact link available on the ChatCache website.
