Data Collection and Storage

Battle.net Auth

When logging in via Battle.net, we receive your BattleTag and WoW character info. This is used strictly for core features (event registration, guild management) and is never shared.

Raider.io Data

We fetch public achievements from Raider.io. This data is only stored in a temporary cache (max 24h) and is not permanently linked to your personal identity.

Google Integration (Family Calendar)

When logging in via Google, we access your basic profile (email/name) for identification. If you use the Calendar Sync features, we access your Google Calendar to import events you choose to sync. We store a copy of these events to display them in your Family Circles. You can revoke this access and stop syncing at any time in your settings.

Availability Data

If you participate in scheduler polls, your selected time availability is stored and visible to Guild Administrators for the purpose of planning events.

Push Notification Data

If you opt-in to Push Notifications, we store a unique browser endpoint and encryption keys. This is used solely to deliver service-related messages and can be deleted instantly by disabling the feature in your settings.

Email Notifications (Brevo)

If you opt-in to Email Notifications, we store your email address and use Brevo (formerly Sendinblue) as our service provider to send you notifications. Your email and notification content are transmitted to Brevo strictly for delivery purposes. You can revoke this consent at any time in your settings.

TeamSpeak Presence

We collect real-time presence data from our TeamSpeak 3 server (nicknames and current channel). This data is displayed in the calendar sidebar and used to send Join Notifications to users who have opted into this feature. This data is processed in real-time and not stored permanently.

Database Storage (MongoDB Atlas)

Your event registrations, character roles, and notification preferences are stored securely in our database, hosted on MongoDB Atlas. This data is linked to your BattleTag ID and is necessary to coordinate team activities effectively.

Hosting (Vercel)

Our website is hosted on Vercel. To provide this service, Vercel collects and processes technical telemetry data (such as IP addresses and browser fingerprints) in their server logs. This is necessary for the technical operation and security of the platform.

Performance Analytics

We use Vercel Analytics and Speed Insights to measure anonymous usage statistics and performance metrics (e.g., page load times). This data is aggregated and does not identify individual users. We use this to improve the user experience of the application.

Cookies

We use purely "strictly necessary" cookies for session management and preference persistence. These are essential for the technical operation of the platform.

Your Rights

GDPR Art. 15-21

You have the right to access, rectify, or erase your data at any time. To exercise these rights, please reach out via the email provided in the Legal Notice.
