Information we collect

Prompt Engineer collects the information needed to provide prompt enhancement, account access, billing, and support.

This may include account details such as name, email address, authentication session data, subscription or credit status, and the prompt content you choose to submit for enhancement.

How we use information

We use information to authenticate users, process prompt enhancement requests, return optimized prompts, manage credits and subscriptions, improve product reliability, and respond to support issues.

  • Authenticate your account and maintain secure sessions
  • Process prompt enhancement and refinement requests
  • Track credit usage, billing status, and subscription access
  • Monitor reliability, security, and abuse prevention
  • Provide customer support and service updates

Prompt content

Prompt content is processed only to provide the enhancement and refinement features requested by the user. We recommend that users avoid submitting highly sensitive personal, financial, health, or regulated data unless they have confirmed it is appropriate for their use case.

Chrome extension data use

The Chrome extension runs on supported AI chat websites in order to detect the prompt composer, let the user trigger prompt enhancement, and open the Prompt Engineer side panel.

The extension stores local authentication state in extension storage and sends prompt text to Prompt Engineer only when the user chooses to enhance a prompt.

Sharing

We do not sell personal information. We may share information with infrastructure, payment, analytics, security, or authentication providers only when needed to operate the service, comply with legal obligations, or protect the service and its users.

Retention and security

We retain information only as long as reasonably necessary for service delivery, legal compliance, dispute resolution, and security purposes. We use reasonable administrative, technical, and organizational safeguards to protect data, but no system can guarantee absolute security.

Your choices

You may request account-related updates or deletion where applicable, and you may stop using the service or uninstall the extension at any time. Some information may be retained when required for legal, security, accounting, or fraud prevention reasons.
