Privacy Policy

Last updated: July 2026

Welcome to Gróa. This Privacy Policy explains what information we collect, how we use it, and the choices you have when you use the Gróa web application at groa.valhalla-drums.com (the “App”).

The App is provided by Valhalla Drums (“we”, “us”, or “our”). By creating an account or using the App, you acknowledge this Privacy Policy.

1. Information we collect

We may collect:

• Account information (email, display name, authentication data). If you sign in with Google, we receive basic profile information Google shares (such as name, email, and photo).
• Profile and app content you create (tasks, journals, meals, books, sport activities, goals, streaks, XP, ranks, achievements), plus optional public username and YouTube handle for membership checks.
• Technical data needed to run the App (session tokens, local storage / PWA caches, approximate device or browser type, diagnostics).
• Advertising-related data from partners such as Google AdSense when ads are shown to non–ad-free users.

2. How we use information

We use information to provide and improve Gróa, calculate progress, show leaderboards, verify optional YouTube membership for ad-free access, show ads when applicable, secure the service, and comply with law.

3. Sharing

We do not sell personal information. We share data with service providers (especially Google Firebase and AdSense), with other users only for public leaderboard fields you enable, and with authorities when required by law.

4. Your choices

You may edit profile settings in the App and request access, correction, or deletion by contacting Valhalla Drums via valhalla-drums.com or the Valhalla Drums YouTube channel.

5. Children

Gróa is not intended for children under 13 (or a higher minimum age required in your country).
