Cygnus Privacy Policy

Effective date: 21 September 2026

Cygnus ("the app") is developed by the developer behind SUBWIND365 Digital Solutions ("we", "us"). This Privacy Policy explains what data Cygnus collects, how it is used, and your choices.

Summary

Cygnus is a subscription-tracking app that stores all of your subscription data locally on your device. We do not operate a server, do not collect your personal subscription data, and do not sell or share your data with third parties.

Data We Collect

Data you enter into the app. Subscription names, prices, billing cycles, categories, renewal dates, and related notes you add are stored only in a local database on your device (SQLite). This data:

Is never transmitted to us or to any third-party server.
Is not backed up to any cloud service by the app itself (unless your device's own operating-system backup, e.g. Android's built-in app backup, is enabled by you).
Is deleted when you uninstall the app or use the in-app "Clear Data" option.

Notifications. Cygnus schedules renewal-reminder notifications using your device's local notification system. Notification content (e.g. "Netflix renews in 2 days") is generated and delivered entirely on-device — no notification data is sent to us or any third party.

Purchases. Cygnus offers an optional one-time lifetime unlock (cygnus_premium_lifetime) processed entirely through Google Play Billing. We do not receive or store your payment details, card number, or billing address — that information is handled directly by Google Play under Google's own Privacy Policy. We only receive confirmation from Google Play that a purchase was completed, which we store locally on your device to unlock premium features.

Data we do NOT collect:

No account or sign-in is required to use Cygnus.
We do not use analytics, advertising, or tracking SDKs.
We do not collect your name, email address, location, contacts, or device identifiers.
We do not access the internet to transmit your subscription data anywhere.

Permissions Used

Permission	Why it's needed
Notifications (`POST_NOTIFICATIONS`)	To show renewal-reminder notifications you configure.
Schedule exact alarms (`SCHEDULE_EXACT_ALARM`)	To deliver renewal reminders at the precise time you set.
Receive boot completed (`RECEIVE_BOOT_COMPLETED`)	To re-schedule your reminders after your device restarts.

Cygnus does not request camera, microphone, contacts, location, storage, or SMS permissions.

Data Sharing

We do not sell, rent, or share your subscription data with third parties. The only third party involved in using Cygnus is Google Play, which processes optional purchases under its own privacy policy.

Data Retention and Deletion

All subscription data lives in local app storage on your device. You can delete it at any time by using the in-app "Clear Data" option in Settings, or by uninstalling the app. Because we do not hold a copy of your data on any server, there is nothing further for us to delete on request — deleting the app or its data on your device is complete removal.

Children's Privacy

Cygnus is not directed at children under 13 and does not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy as the app evolves (for example, if we introduce optional cloud backup or analytics in the future — this page will be updated first and the "Effective date" above will change). Continued use of the app after a change constitutes acceptance of the revised policy.
