Substat is a subscription tracking app built for personal use. This policy explains how your data is handled.
We collect no personal data. All information you enter into Substat — subscription names, amounts, dates, and notes — is stored locally on your device using Apple's SwiftData framework. It never leaves your device and is never transmitted to any server.
Substat offers a Pro subscription via Apple's in-app purchase system (StoreKit). All payment processing is handled entirely by Apple. We never see, store, or have access to your payment information, Apple ID, or any personally identifiable information related to your purchase.
If you enable renewal reminders, Substat schedules local notifications on your device. These notifications are generated and delivered entirely on-device. No notification data is sent to any server.
Substat does not use any third-party analytics, advertising, or tracking SDKs. There are no third parties with access to your data.
Substat does not currently sync data via iCloud. All data remains on your local device only.
Substat does not collect any personal information from anyone, including children under the age of 13.
If this policy changes in a future update, we will update the date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
