1. Personal Information Collection

Bloom: AI Vocabulary Coach (hereafter "the App") collects the following personal information.

1.1 Information You Provide

• Account Information: Email address, name, profile image
• Authentication Information: Sign-in identifiers from Google and Apple accounts
• Guest Use: An anonymous account identifier if you start without signing in. If you later link an account, your existing learning data is transferred to it.
• Photos: Photos you take or select from your gallery
• Learning Data: Extracted words and sentences, progress, review history and accuracy, stickers, language settings
• Support: Your message and contact details for a reply
• Coupons: Coupon codes you redeem

1.2 Information Collected Automatically

• Diagnostics: Device model and OS version, app version, crash logs — Firebase Crashlytics
• Usage Analytics: In-app events such as screen views and feature use, coarse region, device language — Firebase Analytics
• Advertising Identifier: Advertising ID (Android AAID / iOS IDFA), ad impression and click records — Google AdMob
• Push Token: A per-device token used to deliver notifications
• Subscription Status: Product, period and renewal state, app user identifier, store receipt — RevenueCat
• AI Usage Records: Number of AI requests and token usage per account (for enforcing usage limits and preventing abuse)

We do not collect payment details. Card and billing information is handled directly by Google Play and the App Store; the App only receives whether a purchase succeeded and your subscription status.

2. How Photos and Learning Data Are Processed

The core feature of the App turns photos into vocabulary. That involves the following:

• On-device storage: The word cards you create and their photos are stored on your device and used for reviews and stickers.
• Processing for analysis: Photos are compressed and sent through our server (Google Cloud Functions) to OpenAI (word and example generation) and Google Cloud Vision (object detection and positioning). The photo travels inside the request and is not stored as a file on our servers.
• Analysis results: The generated words and examples are stored under a path specific to your account (Firebase Storage) so the App can retrieve them, and are deleted when you close your account.
• Cloud backup (premium): If you use backup, your learning database and the photos attached to your word cards are uploaded to storage dedicated to your account. Backups are kept until you restore or delete them.
• AI study reports: When a report is generated, your learning records (word list, accuracy, review history) are sent to OpenAI. Account identifiers such as your name or email are not included.
• Scene pack photos: The situational photos the App provides (airport, restaurant and so on) are AI-generated material and contain no user personal data.

3. Collection Purpose and Use

• Identifying you, signing you in, and syncing data across devices
• Creating vocabulary from photos, scheduling reviews, and providing study reports
• Verifying subscriptions and providing premium features
• Serving ads to users on the free tier
• Diagnosing errors, improving the service, and statistical analysis
• Responding to support requests

4. Personal Information Retention and Usage Period

• Account Information: Deleted without delay upon account closure
• Learning data on your device: Until you delete it or uninstall the App
• Cloud backups (including photos): Until you delete them or close your account
• Analysis result files: Deleted upon account closure
• Photos sent for analysis: Not stored as files on our servers
• Diagnostics, usage analytics and API logs: Subject to the third-party provider's policies (Google, OpenAI)
• Transaction records required by law: For the period required by applicable law

6. Advertising and Consent

Users on the free tier see ads from Google AdMob. In the EEA, the UK and other applicable regions, a consent dialog (Google User Messaging Platform) is shown when you first open the App, where you can choose whether to allow personalized advertising. You can also reset your advertising ID or opt out of personalized ads in your device settings. Premium subscribers see no ads.

7. Notifications

Study and review reminders are sent only if you enable them in the App, and you can turn them off at any time in the App's settings. A per-device push token is used to deliver them.

8. Security Measures

• All communication is protected with TLS/SSL encryption.
• Backup files and analysis results are stored separately under your account identifier with restricted access.
• API keys for AI services are never shipped in the App and are used only on our servers.
• In-app data is kept in the device's storage.

9. Your Rights

9.1 Access and Correction

You may access your personal information and request corrections.

9.2 Deletion

You can close your account at any time from Profile > Delete account in the App. Doing so deletes:

• Your account information and learning data stored on our servers
• Cloud backup files (including photos) and analysis result files
• Data stored on your device (when you uninstall the App)

9.3 Withdrawal of Consent and Opt-Out

You may withdraw consent for notifications and personalized advertising at any time, and change camera, photo, and notification permissions in your device settings. You may decline to use specific features (for example photo analysis), in which case those features are unavailable.

10. Children's Privacy

This App is intended for users aged 14 and over. Minors may use it with the consent of a legal guardian. If we learn that a minor's personal information was collected without such consent, we delete it without delay.

11. Changes to This Policy

This policy may change due to legal requirements or service improvements. When it does, we post the effective date and the changes on this page, and announce significant changes inside the App.
