Cardo is designed to keep your learning library personal.
1. What Cardo stores
Cardo stores this library data on your device:
- Folders, decks, cards, and deck settings
- App settings and backups you create locally
This data is used to provide the app and is not sent to a developer-operated server.
2. Accounts and analytics
- Cardo does not require an account.
- Cardo does not operate advertising, analytics, or social features.
- Cardo does not collect your card content, browsing history, or contacts.
3. Audio and system services
When you use audio playback, Cardo uses Apple’s system speech services to read card text aloud.
Apple may process requests according to Apple’s own terms and privacy policy.
4. Purchases
- Cardo Pro is a one-time, non-consumable purchase processed by Apple through StoreKit.
- Cardo receives the transaction status needed to unlock the feature.
- Cardo does not receive your payment details.
5. Backups and files
- Backups are created only when you choose to export them.
- Backup files may contain your card content and are not encrypted by Cardo.
- Store and share backup files carefully.
6. Your choices
- You can edit or delete your library inside Cardo.
- You can delete exported backup files from the locations where you saved them.
- Because Cardo does not operate an account system, there is no developer-held account data to delete.
7. Changes to this policy
We may update this policy when the app or applicable requirements change.
The latest version and its update date will always be posted on this page.
