Privacy Policy
Last updated: January 31, 2026
CardWallet is provided free of charge. Use of the Service is entirely at your own risk. Do not store sensitive financial information, authentication secrets, or high-risk cards in the App. This Privacy Policy explains how your data is handled and your responsibilities when using the Service.
1. Data Collection
CardWallet does not require registration and does not collect personal information by default. All card and user data is stored locally on your device and is fully controlled by you.
Cloud backup and synchronization occur only if you sign in with Google and enable the optional backup feature. When enabled, data is stored exclusively in your personal Google Drive. CardWallet does not access, view, monitor, or retain your card data.
2. Local Storage
All cards and related data remain on your device unless you explicitly enable cloud backup. CardWallet has no visibility into locally stored data.
3. Cloud Backup
Optional backups are stored exclusively in your Google Drive account. CardWallet does not operate its own servers and does not access your backups.
Backups are best-effort and may fail due to Google service limitations. CardWallet is not liable for loss, corruption, or unavailability of backup data.
4. Sensitive Information
Do not store credit cards, bank details, PINs, passwords, or authentication secrets. CardWallet is not designed for sensitive or financial data.
5. Advertising
CardWallet is free and supported by Google AdMob advertisements. Card data is never accessed, sold, or used for advertising.
Google AdMob may collect limited device or usage data in accordance with Google’s Privacy Policy. CardWallet does not control Google’s data practices.
6. Updates
This Privacy Policy may be updated at any time. Continued use of the App constitutes acceptance of the updated policy.
By using CardWallet, you confirm that you have read and understood this Privacy Policy and accept full responsibility for any data stored locally or in Google Drive.
