Privacy Policy

Last Updated: August 8, 2026

EnginPeers LLC ("EnginPeers," "we," "us," or "our") operates the EnginPrep web application (the "App"), available at www.enginprep.com / www.enginpeers.com, and related services. This Privacy Policy explains how we collect, use, disclose, and protect information when you use the App or contact us. By using the App, you agree to this Privacy Policy.

1. Information We Collect

A. Information Collected Automatically

When you use the App, certain technical information may be collected automatically by us or by third-party service providers integrated into the App. This may include:

  • Browser type and version
  • Device and operating system information
  • Pages visited and general usage activity within the App
  • Diagnostics and performance information
  • Approximate location derived from your IP address

B. Information You Provide to Us

If you create an account or contact us, we may receive information you choose to provide, such as:

  • Your first name and email address
  • Password (stored securely via Supabase Auth — never in plain text)
  • Profile details such as your engineering discipline and target FE exam date
  • Study session data, practice history, and progress
  • Your marketing email preferences
  • The content of any messages, bug reports, or feedback you send us

C. Payment Information

If you subscribe to a paid plan, your payment is processed by our third-party payment processor, Stripe. We do not collect or store your full payment card details on our servers. Stripe collects and processes that information directly under its own privacy policy. We receive and store limited subscription-related information from Stripe, such as:

  • Your subscription status (for example, trialing, active, or canceled)
  • A Stripe customer identifier and subscription identifier
  • Your current billing period end date
  • Whether your subscription is set to cancel

2. How We Use Information

We may use information to:

  • Operate, maintain, and improve the App
  • Provide study content and app functionality
  • Track your study progress and session history
  • Personalize your experience based on your discipline and exam date
  • Process subscriptions, trials, and payments through our payment processor
  • Manage your account access based on your subscription status
  • Measure usage and app performance
  • Troubleshoot errors and improve reliability
  • Send transactional and account-related emails
  • Send marketing or promotional emails, where you have not opted out
  • Respond to support requests, bug reports, and feedback
  • Protect against misuse, fraud, or abuse
  • Comply with legal obligations

3. Cookies

We use only essential cookies required to keep you signed in and maintain your session. We do not use advertising cookies or third-party analytics or tracking tools. Because we rely only on strictly necessary cookies, no cookie consent banner is presented.

4. Marketing Communications

If you opt in, we may send you marketing or promotional emails about EnginPrep, such as new features, study tips, or offers. You can opt out at any time by using the unsubscribe link in any marketing email or by updating your preferences in your account settings. Opting out of marketing emails does not affect transactional or account-related emails (such as receipts, subscription notices, or password resets), which we may still send you as part of operating the App.

5. Third-Party Services

The App uses third-party services that collect or process data on our behalf, including:

  • Supabase — for authentication, database, and backend services
  • Vercel — for hosting and deployment
  • Stripe — for payment processing and subscription management
  • Resend — for sending transactional and marketing emails

These third parties may process information in accordance with their own privacy policies and terms. We share with them only what is necessary to provide the App. You can review Stripe's privacy practices at https://stripe.com/privacy.

6. Data Retention

We retain information for as long as reasonably necessary to provide the App and maintain records. Practice session data is automatically deleted approximately 90 days after it is created, and unfinished sessions are cleaned up sooner. Subscription and payment-related records may be retained longer as needed to meet legal, tax, and accounting obligations. You may request deletion of your account and associated data at any time by contacting us.

7. Data Sharing

We do not sell your personal information. We may share information in the following circumstances:

  • With service providers that support app functionality, including our payment processor
  • If required by law, legal process, or governmental request
  • To protect our rights, users, or the security of the App
  • In connection with a business transfer such as a merger or acquisition

8. Your Choices and Rights

You may contact us to request access to, correction of, or deletion of your personal information, and you may delete your account at any time by contacting us at team@enginpeers.com. You can opt out of marketing emails at any time as described in the Marketing Communications section above. Depending on where you live, you may have additional rights under applicable privacy laws — such as the right to access, correct, delete, or port your information, or to opt out of certain processing. We do not sell personal information. To exercise any of these rights, contact us at the email above; we will respond as required by applicable law.

9. Children's Privacy

The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, please contact us so we can review and take appropriate action.

10. Security

We use reasonable administrative, technical, and organizational measures to help protect information. Account passwords are never stored in plain text, and payment card details are handled directly by our payment processor rather than stored on our servers. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

11. International Users

If you use the App outside the United States, your information may be processed in the United States or other countries where privacy laws may differ from those in your jurisdiction.

12. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make changes, we will revise the "Last Updated" date above. Your continued use of the App after changes become effective means you accept the updated Privacy Policy.
