Bulk Box is developed and maintained by Meris Lihić, an independent developer. This policy explains what data is collected, why, and how it is used.
Account information (optional)
If you choose to sign in with Apple to use cloud sync, I receive your Apple ID and, on first sign-in, the name you share with the app. This is used solely to identify your account and associate your collection backup with it. Sign-in is not required to use the app.
Collection data (optional)
If you are a premium subscriber and use cloud sync, your card collection data (box names, card quantities, conditions) is uploaded to and stored in Supabase, a third-party cloud platform. This data is linked to your account and used exclusively to sync your collection across your devices. It is never shared or sold.
Purchase and subscription information
If you subscribe to Collector's Edition, your subscription status and purchase history are processed by RevenueCat, a third-party subscription management platform. I do not directly handle payment information — that is managed entirely by Apple.
Card images and data
Card information and images are fetched from the YGOProDeck API and cached locally on your device to reduce repeated network requests. This data does not leave your device.
Crash and error reports
Bulk Box uses Sentry to automatically collect crash reports and error logs when the app encounters a problem. This may include device type, OS version, app version, and a stack trace of the error. This data is used solely to identify and fix bugs. No personally identifiable information is intentionally included in these reports.
The following third-party services are used by Bulk Box. Each has its own privacy policy:
Your collection data, if synced, is stored in Supabase's EU infrastructure. Access is restricted to your authenticated account. Local data stays on your device and is never transmitted unless you explicitly use cloud sync.
You can delete your account and all associated cloud data at any time by signing out and contacting me at the address below. Local data can be removed by deleting the app.
Bulk Box is not directed at children under 13 and does not knowingly collect data from them.
If this policy changes meaningfully, the "Last updated" date above will reflect that. Continued use of the app after changes constitutes acceptance.
