Privacy Policy
Last updated: April 2026
1. Introduction
This Privacy Policy explains how BARU collects, uses, and protects information when you use our mobile app and website.
2. Information We Collect
Study data on your device: BARU stores decks, cards, study progress, and app preferences locally on your device.
Downloaded deck data: When you download decks from Explore, the app retrieves deck content from our servers and stores it locally.
Advertising and diagnostics data: If ads are enabled, third-party ad providers may collect device and usage data (such as advertising identifiers) according to their own policies.
3. How We Use Information
We use data to:
- Provide core flashcard and study functionality
- Store and restore your local study progress
- Deliver downloadable deck content and deck updates
- Maintain app quality, reliability, and security
- Serve ads where applicable
4. Data Storage
BARU is currently offline-first. Most study data is stored on your device. If you uninstall the app, locally stored data may be removed.
Decks from Explore are delivered from our backend and cached locally in the app.
5. Third-Party Services
We may use third-party providers for services such as advertising, diagnostics, hosting, and app infrastructure.
These providers process data under their own privacy policies. We do not sell your personal information.
6. Your Choices
- You can disable study notifications in app settings.
- You can manage ad personalization in your device or Google settings.
- You can remove local app data by clearing app storage or uninstalling the app.
7. Children's Privacy
BARU is not directed to children under 13, and we do not knowingly collect personal information from children under 13.
8. Changes to Privacy Policy
We may update this Privacy Policy from time to time. We will post updates on this page and revise the "Last updated" date.
