Privacy Policy

Overview

Flashback is a spaced-repetition learning application that helps you turn technical knowledge into long-term memory. This policy explains what personal data we collect, why we collect it, and how we handle it.

Data We Collect

We collect only what is necessary to provide the service:

• Email address — used to create and identify your account.
• Password — stored as a one-way cryptographic hash; we cannot read it.
• Learning content — subjects, topics, sections, and flashcards you create inside the app.

We do not collect your name, location, phone number, payment information, or any device identifiers.

How We Use Your Data

• Authenticate you when you sign in.
• Store and sync your learning content across devices.
• Send account-related emails (e.g. email verification).

We do not use your data for advertising, analytics profiling, or any purpose beyond operating the app.

Data Sharing

We do not sell, rent, or share your personal data with third parties. Your data is stored on our own servers and is never disclosed to external parties except where required by law.

Data Retention and Deletion

Your data is retained for as long as your account exists. You may request deletion of your account and all associated data at any time by contacting us at the address below. We will process deletion requests within 30 days.

Security

All communication between the app and our servers is encrypted in transit. Passwords are never stored in plain text. We apply industry-standard practices to protect your data.

Children's Privacy

Flashback is not directed at children under the age of 13. We do not knowingly collect personal data from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

Changes to This Policy

If we make material changes to this policy, we will update the date at the top of this page. Continued use of the app after changes constitutes acceptance of the revised policy.
