Your privacy is critically important to us. Included below is our policy for how we handle your data.
1. Information We Collect
- Account Information: Name, email address, and profile picture (via authentication providers).
- Usage Data: Presentations created, answers given during sessions, and spaced-repetition performance statistics.
- Payment Information: We do NOT store your credit card information. All payment processing is handled by our third-party payment processor, Stripe.
2. How We Use Information
We use the information to operate, maintain, and improve the Service, specifically:
- To optimize the "spaced repetition" algorithm for your learning.
- To process payments and manage subscriptions.
- To send administrative information, such as policy changes or security alerts.
3. Payment Processing
We use Stripe for payment processing. We do not store or collect your payment card details. That information is provided directly to our third-party payment processors whose use of your personal information is governed by their Privacy Policy. These payment processors adhere to the standards set by PCI-DSS as managed by the PCI Security Standards Council.
4. Security
The security of your Personal Information is important to us. We use commercial industry standards (such as HTTPS/TLS encryption) to protect your data during transmission.
5. GDPR & Global Standards
We are fully committed to GDPR compliance. Users in the European Union have specific rights regarding their data, including the right to access, rectify, or delete their personal information. You can exercise these rights by contacting us at hello@retenbo.com.
