Privacy Policy
Last updated: May 2026
1. Data We Collect
Promptuner collects minimal data necessary to operate the service. When you use the Pro plan, we store your account email and subscription status. We do not log, store, or retain the content of your prompts.
2. How Enhancement Works
When you trigger a prompt enhancement, your current prompt text is sent through our secure API proxy to the AI model provider. This request is not logged on our servers. The response is returned directly to your browser.
3. Local Storage
Your prompt library and settings are stored locally in your browser using the Chrome Extension storage API. This data never leaves your device unless you opt into cloud sync (Pro plan).
4. Third-Party Services
We use Lemon Squeezy for payment processing. Their privacy policy governs data collected during checkout. We do not store payment card details.
5. Contact
