Privacy Policy

Overview

This policy describes how PromptShield ("PromptShield," "we," "us") handles information when you use the PromptShield browser extension, our API, and this website.

Information you provide

• Email address for account sign-in and verification.
• Feedback you submit (message, optional reply email, extension version).
• Support emails you send to support@promptshield.app.

Prompt processing

When you request cloud optimization, PromptShield sends prompt-related content to our API over HTTPS. The extension does not call model providers directly — provider credentials remain on PromptShield servers.

If the service is unavailable, PromptShield may fall back to local-only review where your build supports it.

Data on your device

By default, the following stay in your browser unless you choose to share them in support or feedback:

• Saved prompts (Library)
• Optimization History
• Personalization preferences
• Settings and onboarding progress
• Free-plan usage counts
• Signed-in session tokens for account features

Accounts

We link your verified email to an account so Pro access can be restored after reinstall. Authentication uses verification codes and rotating session tokens stored securely on our servers.

Billing

Stripe processes subscriptions and payment cards. We store subscription status and Stripe references — not full card numbers.

Retention

Local usage records may be trimmed over time on your device. Account and billing records may be kept for reconciliation, fraud prevention, and legal obligations. Deletion requests are handled per our support process.

Your choices

Email support@promptshield.app to ask about your data or request account deletion. Uninstalling the extension removes local data from that browser profile.
