Privacy Policy — MacTemClean

Effective Date: August 31, 2026 App: MacTemClean — macOS disk cleaner Developer: San Ventura Teknologi, PT. (https://s19i.com) Contact: founder@s19i.com

1. Summary

MacTemClean is a local-only utility. We do not collect, store, or transmit your personal data. We do not track you, we do not use third-party analytics or advertising SDKs, and we do not sell your data.

All scanning and cleaning happens on your Mac, only inside folders you explicitly grant access to.

2. Data We Do Not Collect

No account required — no name, email, or password collected.
No files are uploaded to our servers. File names, sizes, and paths are read only to calculate sizes and display them in the app.
No browsing history, location, contacts, or financial data collected.

3. Data Processed Locally (On-Device Only)

When you grant access (via macOS Security-Scoped Bookmark), the app:

Reads directory listings and file metadata (size, modification date) for these user-domain locations only:
~/Library/Caches, ~/Library/Application Support/Caches, ~/Library/Logs, ~/Downloads/.TemporaryItems, ~/Library/Containers/.../Data/tmp, ~/Library/Developer/Xcode/DerivedData, ~/Library/Developer/Xcode/Archives, ~/.Trash
Calculates allocated sizes using totalFileAllocatedSize and shows them in the UI (System Data Breakdown).

This data never leaves your device and is not sent to San Ventura Teknologi, PT. or any third party.

File deletion uses macOS FileManager.trashItem(at:) — items are moved to Trash (recoverable), not permanently deleted by our servers.

4. Permissions

Files and Folders: Access requires explicit user consent via the system Open Panel (“Grant Access — Allow Library”). You can revoke by removing the bookmark in SecurityScopedBookmarkStore (UserDefaults) or by removing the app’s access in System Settings.
Network: com.apple.security.network.client entitlement is used only for StoreKit (in-app purchases). No file content is transmitted over the network.
Disk Space: NSPrivacyAccessedAPICategoryDiskSpace (E174.1) — to show free/used space via volumeAvailableCapacityForImportantUsage.

5. In-App Purchases (StoreKit)

If you use “Support with a coffee” or “Lifetime Supporter”:

Purchases are processed directly by Apple via StoreKit 2. We do not receive your payment details (card, Apple ID password).
Product IDs: [private-product-id] (consumable, 1d–1m) and [private-product-id] (non-consumable). No lottery or random rewards.
Transaction verification uses Apple’s Transaction.currentEntitlements on-device. No purchase data is stored on our servers.

See MacTemClean/Presentation/Services/SupporterStore.swift and CoffeeStoreViewModel.swift.

6. Third Parties

No analytics (Firebase, Mixpanel, etc.).
No advertising SDKs.
No embedded web trackers. The only external link is https://s19i.com/?ref=mactemclean_about in AboutView.swift:40, which opens in your system browser.

7. Data Retention

Because we do not collect data on a server, there is nothing to retain or delete server-side. Local bookmarks and preferences (UserDefaults: app.persona, app.theme, bookmarks) remain on your Mac until you uninstall the app or reset them.

8. Children’s Privacy

MacTemClean is rated 4+ (no objectionable content, no chat, no user-generated content). It does not knowingly collect data from children, as it collects no data from anyone.

9. Security

All operations respect macOS App Sandbox. We do not access system files, other users’ home directories, or network shares. Code is open to Apple App Review; file operations are logged locally via os.Logger (AppLog).

10. Your Rights

Since no personal data is collected, there is no data to access, correct, or delete on our servers. For any privacy question, contact us and we will respond within 7 days.

11. Changes

If this policy changes, we will update the Effective Date above and publish the new version at https://s19i.com/mactemclean/privacy and in this repository (docs/privacy-policy.md).
