Privacy Policy

PromptMaster provides a public AI prompt library, saved prompt workflows, and an AI prompt optimizer. This policy explains what we collect, why we collect it, and how advertising and analytics providers may process data when ads are enabled.

Information We Collect

  • Account information such as email address, display name, and OAuth profile identifiers.
  • Saved prompts, favorites, copy events, optimizer requests, and usage events needed to run the service.
  • Technical data such as device, browser, referrer, page URL, approximate location, and performance events.
  • Payment and subscription events processed by Stripe. We do not store full card numbers.

How We Use Information

We use data to provide the prompt library, keep users signed in, save prompt workflows, measure product performance, prevent abuse, improve search and content quality, and operate paid subscription features. User-created private prompts are not used for model training by this application.

Cookies, Analytics, and Advertising

PromptMaster uses cookies for sessions, OAuth state, anonymous optimizer limits, analytics, and security. We use Vercel Analytics and Speed Insights to understand aggregate traffic and performance. If advertising is enabled, Google AdSense or other advertising partners may use cookies, device identifiers, web beacons, and similar technologies to serve, measure, and personalize ads, subject to user consent where required.

Third-Party Services

The service may share limited data with infrastructure and product providers including Vercel, Supabase, Stripe, OAuth providers, OpenAI or another configured LLM provider, analytics providers, and advertising partners. These providers process data under their own terms and privacy policies.

User Choices

You can sign out, avoid saving private prompts, clear cookies in your browser, and request deletion of account-associated data. Users in regions with consent requirements may be shown additional choices before personalized ads or analytics cookies are used.
