Grand Line Deck is an "Offline First" utility. We do not require an account, and we do not collect, store, or transmit any personal data (such as names, emails, or location) to any external servers.
All deck data and collection information created within the app are stored locally on your device using MMKV/Local Storage. This data remains on your device unless you manually clear the app data or uninstall the app.
The app may provide links to official rulebooks or external TCG resources. We are not responsible for the privacy practices of these external sites.
We may update this policy occasionally. Any changes will be reflected by the "Last Updated" date at the top.
