Privacy Policy

We store your account details and the prompts you enhance so you can find them again. Your prompts are private to your account, we do not sell data, and we do not train models on your content. You can delete any prompt at any time, or ask us to delete your account entirely.

• Account data — your email address, an optional display name, and your plan. Authentication is handled by Supabase.
• Prompt data — the text you submit, the enhanced result, and the options you chose (category, target model, detail level, tone).
• Usage data — timestamps, which AI provider served the request, token counts and response times. We use this to keep the service running and to spot abuse.
• A hashed IP — for logged-out visitors only, so the daily free allowance can be enforced. It is salted and one-way hashed; we cannot recover the original address from it, and it is deleted after seven days.
• Payment data — handled entirely by Stripe. We store only your Stripe customer and subscription identifiers, never card details.

To enhance a prompt we send its text, plus our system instructions, to the AI provider currently in use — Groq, Google (Gemini), OpenAI or Anthropic (Claude). They process the request under their own API terms. We do not enable any training-on-input option offered by these providers.

Your stored prompts are protected by Postgres row-level security, so no other Prompt Mate account can read them. Our staff access production data only when necessary to investigate a fault you have reported.

• Supabase — database, authentication and storage
• Netlify — hosting and content delivery
• Stripe — payment processing
• Groq, Google, OpenAI, Anthropic — AI inference (whichever is active)

Prompts stay until you delete them or close your account. Usage logs are kept for twelve months. Anonymous IP hashes are deleted after seven days. Deleting your account removes your profile, prompts and templates.

Depending on where you live you may have the right to access, correct, export or delete your personal data, and to object to certain processing. Email privacy@promptmate.cloud and we will respond within 30 days.

We set cookies that keep you signed in. That is all — there is no advertising or cross-site tracking on Prompt Mate.
