Privacy Policy

Last updated: April 15, 2026

Overview

SubZero ("the App") is a subscription tracking app developed by an independent developer. Your privacy is important to us. This policy explains what data SubZero collects and how it is used.

Data Collection

SubZero does not collect any personal data.

All subscription data you enter (names, prices, dates, notes) is stored exclusively on your device and in your personal iCloud account. We have no access to this data.

iCloud Sync

If you have iCloud enabled, SubZero uses Apple's CloudKit to sync your data across your Apple devices. This data is stored in your private iCloud container and is governed by Apple's Privacy Policy. We cannot read, access, or share this data.

Local Notifications

SubZero may send local notifications (renewal reminders, trial expiry alerts, monthly summaries) if you grant permission. These notifications are generated entirely on your device. No notification data is sent to any server.

In-App Purchases

SubZero offers optional in-app purchases (SubZero Pro upgrade and tips). All transactions are processed by Apple through the App Store. We do not collect or store any payment information.

Analytics & Tracking

SubZero does not include any third-party analytics, tracking, or advertising SDKs. We do not use cookies, fingerprinting, or any other tracking technology.

Third-Party Services

SubZero does not share data with any third party. The only external service used is Apple's iCloud, which is entirely under your control.

Data Storage

Children's Privacy

SubZero does not knowingly collect information from children under 13. The app does not require account creation or personal information to function.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date.
