1. What PromptRefiner does

PromptRefiner provides a website and browser extension that help you rewrite prompts for AI tools like ChatGPT, Claude, and Gemini.

2. Data we collect

  • Account data: name, email, and authentication credentials when you create an account or sign in.
  • Subscription data: plan, Stripe customer/subscription identifiers, and subscription status.
  • Usage data: generation counts and timestamps used to enforce monthly plan limits.
  • Coupon redemption data: coupon code usage state and redemption timestamp.

3. Prompt data handling

  • When you use Generate or Refine, your prompt text is sent to the PromptRefiner API and then to Azure OpenAI to produce an improved prompt.
  • Prompt text is processed for the request itself. In the current implementation, prompt text is not written to the app database.
  • We store only generation events (for limits/usage), not a full saved history of your prompt content.

4. Browser extension permissions

  • The extension runs only on chat pages for ChatGPT, Claude, and Gemini.
  • It reads the prompt text you type in the active chat input when you use the extension action.
  • It can write the improved prompt back into the same chat input when you click Insert.
  • It does not request broad browsing history access and does not track unrelated sites.

5. Third-party services

  • Stripe: payment and subscription processing.
  • Azure OpenAI: prompt transformation and clarification generation.
  • PostgreSQL (via Prisma): account, subscription, coupon, and usage records.

6. How we use your data

  • Provide authentication and account access.
  • Run prompt generation/refinement requests.
  • Enforce plan limits and show usage.
  • Process subscriptions, upgrades, and coupon redemption.
  • Protect the service from abuse and operational failures.

7. Data retention

We retain account, billing, and usage records as needed to operate the service and meet legal or financial obligations. Prompt text is handled per request and is not stored in our app database by default.

8. Your controls

  • You can sign out at any time from web or extension.
  • You can stop data flow from the extension by disabling it.
  • You can request account/privacy help through the support channel on promptrefiner.io.

9. Policy updates

We may update this policy when product behavior changes. We will update the date at the top when changes are published.
