Privacy Policy

NFC Card Manager ("the App") is developed by John Irianto Susanto. This Privacy Policy explains how the App handles information when you use it.

The App is designed with privacy as a core principle. We do not collect, store, or transmit any personal data to external servers. All NFC card data is stored exclusively on your device.

The App does not collect any personal information. The following data is stored locally on your device only:

• NFC card UID and raw card data (stored in device SharedPreferences)
• Custom card names you assign
• Card tech type and scan timestamp

This data never leaves your device and is not shared with us or any third party.

• NFC — Required to read and emulate NFC cards. No data is sent externally.
• VIBRATE — Used to provide haptic feedback when a card is scanned.
• INTERNET — Used only by Google AdMob to display advertisements. Not used by the App itself.
• ACCESS_NETWORK_STATE — Used by AdMob to check network availability for ads.

The App displays banner advertisements provided by Google AdMob. Google may collect and use data to serve personalized ads based on your interests.

You can opt out of personalized ads via your device settings: Settings → Google → Ads → Opt out of Ads Personalization.

• All card data is stored locally on your device using Android SharedPreferences
• No data is transmitted to any server or cloud service by the App
• Uninstalling the App permanently removes all stored card data from your device

• NFC Card Emulation uses Android Host Card Emulation (HCE). Not all card types can be fully emulated due to hardware security restrictions.
• This App is intended for personal, educational, and testing purposes only. Users are responsible for complying with applicable laws regarding NFC card emulation in their region.
• The developer is not responsible for any misuse of the App.

This App is not directed at children under the age of 13. We do not knowingly collect any personal information from children. If you believe a child has provided personal information through this App, please contact us immediately.

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated date. We encourage you to review this page periodically.

Continued use of the App after changes constitutes acceptance of the updated policy.
