Privacy Policy

What we collect

Memory Lab stores only what is needed to run the service:

• Your email address — used for account authentication and admin notifications.
• Your exercise data — the cards you study, your review history and SRS scheduling state (interval, ease factor, due dates), and your game scores.
• Your settings — session length, cards per session, active languages, and kanji hint mode.
• Session logs — completed session records used to calculate streaks and display your 90-day history on the dashboard.

Nothing else is collected. There is no device fingerprinting, no IP logging beyond what AWS infrastructure records as a matter of course, and no collection of health or biometric information. This site is a training tool, not a cognitive assessment.

How your data is used

• Your email is used to log you in and to send account-status notifications (approval, denial). It is not used for marketing.
• Your exercise data drives the spaced-repetition algorithm (SM-2) that schedules your reviews. It is never used for any other purpose.
• Your game scores are stored so you can see your own history. They are visible only to you.

Who can see your data

Your exercise data and scores are visible only to you. The site administrator (Tracy Elsinger) can see your email address for account management purposes (approving or denying sign-up requests) and can delete your account and all associated data on request. No one else has access.

There is no advertising, no analytics service, no third-party tracking, and no sale or sharing of data with any third party.

Data retention

Your data is retained for as long as your account is active. Session history older than 90 days is excluded from dashboard statistics but the underlying records are not automatically purged — full deletion requires deleting your account. When your account is deleted, all associated data (exercise records, sessions, scores, settings, and your Cognito credentials) is permanently removed from all systems.

Your rights and how to delete your account

You have the right to access, correct, and delete your data. To delete your account and all associated data, email photographix4@gmail.com. Deletions are processed manually by the site administrator and completed within a reasonable time. You may also change your password at any time from the account menu.
