Privacy Policy

Last updated: October 8, 2026

1. Who provides CronMaster

CronMaster is provided by the independent developer of the CronMaster app ("we", "us"). For privacy questions, contact 1095288658@qq.com.

2. Scope

This Privacy Policy describes how CronMaster handles information when you use the iOS app (including related Share Extension, App Shortcuts, and home-screen Widget features, if available).

3. Information stored on your device

CronMaster stores the following only in the on-device app sandbox (and, where needed for Widgets / Share / Shortcuts, in the CronMaster App Group on the same device):

• Cron expressions, natural-language drafts, notes, folders, history, and custom templates you create
• App preferences such as theme, font size, language, timezone favorites, and display options
• A local marker indicating whether Pro has been unlocked via purchase or restore
• Optionally, an expression you pin for the home-screen Widget

We do not maintain a CronMaster server copy of this content.

4. Information we do not collect

• No CronMaster user accounts or sign-in
• No cloud sync of your expressions or notes to our servers
• No advertising, no ad networks, and no use of the Advertising Identifier (IDFA) for tracking
• No analytics SDKs that upload your cron expressions or personal content to us
• No sale of personal data

5. Purchases

Pro unlock is a non-consumable in-app purchase processed by Apple. Payment details are handled by Apple under Apple's terms and privacy policy. After a successful purchase or restore, CronMaster stores only a local unlock flag on your device so Pro features remain available offline.

6. Operating system and Apple services

Your device operating system and Apple may process limited technical information (for example App Store receipt validation, or optional system diagnostics you choose to share with Apple). That processing is controlled by Apple, not by a CronMaster backend.

7. Sharing features on your device

If you use Share Extension, Shortcuts, or Widget features, data may move between CronMaster components on the same device through the App Group. This remains local unless you yourself export, share, or copy content out of the app using iOS system share sheets or Files.

8. Children

CronMaster is not directed to children under 13 (or the equivalent minimum age in your region). We do not knowingly collect personal information from children.

9. Retention and deletion

Local data remains on your device until you delete it in the app or uninstall CronMaster. Uninstalling the app removes the app sandbox data (and related App Group data used only by CronMaster). We cannot remotely delete data from your device because we do not host it.

10. International users

CronMaster is intended for overseas distribution and processes data locally on your device. Because we do not operate a CronMaster cloud database of your expressions, we do not transfer your app content to our servers across borders.

11. Changes to this policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top will change when we do. Continued use of CronMaster after an update means you acknowledge the revised policy.
