Transparency & Security — Plinie

Last updated: March 28, 2026

1. Principles

Plinie processes data based on:

• minimal collection,
• specific purpose,
• controlled access,
• continuous security review.

2. Account security

• authentication through trusted providers,
• biometric support on compatible devices,
• permission separation by role (guardian vs. child),
• option to sign out and delete the account from within the app.

3. Platform security

• data protection in transit and at rest using the features of the vendors we use,
• operational monitoring,
• continuous improvement of security practices.

4. OCR, AI, and human review

• OCR extraction happens on the device before the AI step — for schedule and exam imports as well as photos of study material; the images are not uploaded and, for study-material photos, only the recognized text is stored with the study session,
• import and classification results may contain noise and should be reviewed,
• AI-generated quizzes and plans are intended as pedagogical support.

5. YouTube use

• YouTube links are only offered when that permission is enabled on the student's profile.
• Without that permission, the app must not suggest YouTube links in the study and quiz flows.

6. Security incidents

Relevant incidents are handled as a technical priority. When applicable, affected users may be notified through appropriate channels.

7. Recommended best practices

• keep your device and operating system up to date,
• use strong authentication with your login provider,
• avoid sharing accounts,
• review imported school data periodically.

8. Contact channel
