Third-party services
AWS Exam Prep relies on these services to function. Each is bound by its own privacy policy.
- AI service for explanations. Question text and your answer are sent over HTTPS; no personal info attached.
- Firebase Authentication. Account login.
- Firestore. Stores progress.

AI processing
AWS Exam Prep sends some of your content to an AI model for processing. The AI provider receives only the content needed for the task — not your user ID, email, or any other personal identifier. We do not use your content to train any model.
Tracking
AWS Exam Prep does not track you across other apps or websites. We do not share data with advertising networks, analytics platforms used for cross-app profiling, or data brokers.
Your rights
- Access — request a copy of your data by emailing us.
- Delete — see Delete Account below.
- Correct — edit your profile in the app, or email us for help.
- Object — opt out of optional features in iOS Settings.
Data retention
We retain your data as long as your account exists. After you delete your account, all personal data is permanently removed within 30 days. Anonymous diagnostics may be retained longer in aggregated form.
Children's privacy
AWS Exam Prep is not directed at children under 13. We do not knowingly collect data from children under 13. If you believe we have, contact us and we will delete it.
Changes to this policy
If we change this policy materially, we will notify you in the app and update the date at the bottom of this page.
