Privacy
Policy

Subcharge is a subscription tracking and reminder app. This Privacy Policy explains what information the app stores, how it is used, and the choices you have.

Subcharge is provided by the Subcharge app developer. For privacy questions, contact us at subcharge@aierlabs.com.

Subcharge lets you enter information such as:

• Subscription names, prices, billing cycles, renewal dates, trial dates, categories, notes, and reminder preferences
• Payment card details you choose to save in the vault, including card name, cardholder name, card number, expiration date, CVV, bank name, card network, billing date, due date, and notes
• App preferences such as theme, currency, onboarding status, and display name

Subcharge is designed as a local-first app.

• Subscription records and reminder records are stored locally on your device using the app database.
• Card vault data is stored locally using secure device storage.
• Preferences are stored locally on your device.
• We do not operate a Subcharge account server for syncing your subscriptions or cards.
• We do not sell your personal information.

If you delete the app, your local app data may be deleted from the device depending on your operating system and backup settings.

If you enable reminders, Subcharge requests notification permission and schedules renewal or trial reminders on your device. Notification content can include the subscription name and renewal or trial date. Subcharge does not request or use push notification tokens for a Subcharge server.

You can disable notifications in your device settings.

Subcharge may use your device passcode or biometric authentication to reveal vault details. Biometric authentication is handled by your device operating system. Subcharge does not receive or store your fingerprint, face, or biometric template.

Subcharge may connect to third-party services for app features:

• Frankfurter API, used to fetch currency exchange rates. Currency codes may be sent as part of the exchange-rate request.
• Hunter logo service, used to load public brand logos for subscription names. Logo requests may reveal the requested logo domain to that service.
• Google Play and Android system services, used for app distribution, operating-system features, notifications, and app security.

These third parties may process technical information such as IP address, device/network metadata, and request details according to their own policies.

Subcharge is not a payment processor and does not charge your saved cards. Card details entered in the vault are for your own reference. We do not intentionally transmit your saved card number or CVV to a Subcharge server.

Subcharge is not intended for children under 13. We do not knowingly collect personal information from children.

We do not sell your data. We do not share your locally stored subscription or vault data with advertisers or data brokers.

Your data may still be handled by:

• Your device operating system and device backup settings
• Third-party services described above when network-based features are used
• Legal authorities if required by applicable law

We use device-provided storage and authentication features where available, including secure storage for vault records. No method of storage or transmission is completely secure, so you should use a secure device passcode and keep your device updated.

You can:

• Add, edit, archive, or delete subscription and card records in the app
• Disable reminders in the app or notification permission in system settings
• Change app preferences such as theme and currency
• Delete the app to remove local app data from the device, subject to your operating system and backup settings

We may update this Privacy Policy as Subcharge changes. If we make material changes, we will update the effective date and make the updated policy available.
