Privacy Policy

Last updated: October 2, 2026

Template: have a lawyer review before launch. This page is a starting point and is not legal advice.

ChatDeck is built local-first. This policy explains what stays on your device, what we store on our servers, and which third parties help us run the service.

Data that stays in your browser

Your conversation content from ChatGPT, Claude, Gemini and Grok, and the full-text search index built from it, are stored in your browser's IndexedDB. This data is never uploaded to ChatDeck servers. Uninstalling the extension or clearing site data removes it.

Data we sync

If you sign in, we sync only the items you create inside ChatDeck so they follow you across devices:

  • Folders and pinned conversations (titles and identifiers, not message text)
  • Saved prompts and prompt chains
  • Tag rules and tags
  • Message bookmarks
  • Extension settings

Synced data is encrypted at rest using AES-256-GCM. We also store your email address and your license or subscription status.

AI summarization

On premium plans, two actions can summarize a long chat: adding a past chat as context with @@, and “Carry this chat forward” into a new chat. Only when you use one of them, the text of the chat you selected is sent through our server to OpenAI to produce a summary for that single request. We do not store this text and do not use it to train models. On the free plan these summaries are made in your browser, so no conversation text leaves it.

Third-party processors

  • LemonSqueezy processes payments and acts as merchant of record. We never see your full card details.
  • Resend delivers transactional email, such as sign-in codes and receipts.
  • OpenAI generates summaries, only when you use @@ context or Carry forward on a premium plan.

What we do not do

  • We do not sell your personal data.
  • We do not run third-party advertising trackers in the extension.
  • We do not read or store your AI conversations on our servers.

Retention and deletion

Synced data is kept while your account is active. You can delete your account at any time by contacting us, and we will remove your synced data within 30 days, except where we must keep billing records by law.

Your rights

Depending on where you live, you may have rights to access, correct, export or delete your personal data. To exercise them, email hello@chatdeck.app.

Changes

If we make material changes to this policy, we will update the date above and notify signed-in users by email.
