Privacy Policy

Effective date: March 27, 2026. Last updated: March 27, 2026.

This Privacy Policy explains how WordMaster collects, uses, stores, and shares information when you use the WordMaster mobile application and related support pages.

Summary: WordMaster uses Firebase for authentication and cloud sync, RevenueCat for subscription status, AdMob for rewarded ads, and Groq for optional AI learning content. We do not sell personal data.

1. Information We Collect

1.1 Information you provide directly

Account details such as email address, display name, and profile photo.
Sign-in details when you use email/password, Google Sign-In, or Sign in with Apple.
Profile and onboarding data such as age range, learning level, goals, native language, target language, study preferences, and struggle areas.
Support emails you send to us.

1.2 Information created while you use the app

Learning progress, learned words, favorites, test results, streaks, XP, badges, and settings.
Leaderboard data such as display name, avatar, and XP if you use social or ranking features.

1.3 Automatically collected information

1.4 Microphone and speech data

Speaking exercises use microphone and speech recognition permissions only when you actively start a pronunciation-related feature. We do not claim to store raw voice recordings as part of normal app use.

1.5 AI learning content

Some optional learning modes use Groq to generate short stories or dialogue exercises. The prompts are limited to vocabulary words and generated scene context. WordMaster does not intentionally send your full learning history, scores, or account profile to Groq for these requests.

3.3 RevenueCat

RevenueCat helps us manage subscription entitlements and purchase restoration. Payment processing is handled by Apple or Google, not by us directly.

3.4 Google AdMob and tracking permission

WordMaster may show rewarded ads in the free version. On iOS, we may ask for tracking permission before requesting production ads that rely on Apple tracking rules. If permission is denied, rewarded ads may still be shown in a more limited or less personalized way depending on platform behavior and store settings.

Google Privacy Policy

3.5 Groq

Groq is used for optional AI-generated stories and roleplay dialogues. If the AI service is unavailable or not configured, WordMaster falls back to local non-AI content.

4. Data Sharing

We do not sell personal data. We share data only with service providers that help operate WordMaster or when required by law.

5. Data Retention

Account and progress data are kept while your account remains active.
If you delete your account in the app, our primary app records are deleted or queued for deletion from our active databases as part of the deletion flow.
Some backups, billing records, crash logs, and provider-side logs may remain for limited periods under the retention rules of Firebase, Apple, Google, RevenueCat, Groq, or other processors.

6. Your Choices and Rights

You can access, edit, or update profile details inside the app.
You can disable notifications from device settings or in-app settings.
You can delete your account in the app from Settings > Account > Delete Account. For security, we may ask you to confirm your sign-in method again before deletion.
You can restore or manage subscriptions through the store account that billed you.

7. Children

WordMaster is intended for users age 13 and older and is not directed to children under 13.

8. International Transfers

Your information may be processed in countries other than your own by the service providers described above.

9. Security

We use standard technical and organizational measures designed to protect your information, but no system can be guaranteed to be completely secure.
