Effective date: August 1, 2026

In short: App Lock processes data on your device. We do not upload your photos, videos, pattern data, or Family Controls selection tokens to developer-operated servers.

The App does not include advertising SDKs, third-party analytics SDKs, or cross-app tracking.

App Lock (“the App”) is an iOS utility for managing app access and focus sessions. Current features mainly include app locking, pattern verification, scheduled and temporary unlock, focus modes, Screen Time–related insights, optional intruder capture, plus smart cleaner, album cleanup, smart cutout, and PDF tools. This Privacy Policy explains how information is handled.

App locking and focus modes rely on Apple’s Screen Time / Family Controls frameworks. The App is not Apple’s built-in Screen Time app. Available capabilities depend on your iOS version, authorization results, and Apple API limits. Use these features only on devices you are authorized to manage.

The App does not offer a Privacy Vault / Encrypted Space, disguised unlock screens, Notification Center–based unlocking, or tools that generate official identity documents such as IDs, passports, or diplomas.

1. Who We Are

The App is published as App Lock (Chinese name: 应用锁) with bundle identifier com.nickgao.lock. For privacy questions, see Section 13 (Contact).

2. Information We Collect

We do not collect personal data through routine App use. The App does not require an account, sign-in, email, or phone number.

We do not operate developer-controlled servers that receive your photos, videos, cutout results, PDFs, pattern data, intruder-capture photos, or Family Controls selection tokens.

If you email us, information you voluntarily include is used only to respond to your request.

3. How Features Use Data (On-Device)

3.1 App Lock and Focus Modes

  • After you authorize Screen Time / Family Controls, the App can use system APIs to select apps or categories to restrict and present system Shield screens.
  • Selection state, lock status, temporary-unlock deadlines, and focus settings are stored on-device and may sync via the App Group group.com.nickgao.lock between the main app and system extensions (Device Activity Monitor, Shield Configuration, Shield Action, Screen Time Report) so re-locking, shield UI, and unlock handoff can work.
  • When you tap Unlock on a system Shield, the extension only writes a local App Group flag; you then open the App manually to complete pattern verification. The App does not use Notification Center to carry the unlock flow.
  • This data is used only to provide features you enable and is not uploaded to developer servers.

3.2 Unlock Credentials and Biometrics

  • Pattern-lock data is stored locally for on-device verification.
  • Face ID / Touch ID verification is performed by the system (LocalAuthentication). The App does not obtain, store, or upload your biometric raw data or templates.

3.3 Intruder Capture

If enabled, failed unlock attempts may trigger an on-device camera capture stored locally for your review and deletion. Camera permission is required; the feature is off by default. Captures are not uploaded to developer servers.

3.4 Smart Cleaner, Album Tools, Cutout, and PDF

  • Smart cleaner / album tools: with Photos permission, media is analyzed, compressed, or organized locally; deletions and saves require your action.
  • Smart cutout: on-device frameworks (such as Vision and Core Image) create segmentation previews and exports.
  • PDF tools: import, merge, split, watermark, sign, and encrypt documents in a local document library.

Temporary processing data is discarded after the session unless you save or export the result.

3.5 Widgets and URL Schemes

Widgets or deep links (such as piccompress://) may write local flags to open a feature (for example, smart cleaner). This state stays on-device / in the App Group and is not used for cross-app tracking.

4. Permissions

  • Screen Time / Family Controls: app locking, focus modes, and related restrictions.
  • Camera: intruder capture you explicitly enable, and in-app capture where offered by cleaner / cutout flows.
  • Photos (read/add): choose, process, and save media when you ask.
  • Face ID / Touch ID: local identity verification.

You can revoke permissions in iOS Settings. Some features will stop working without them.

5. Local Storage

The App may store preferences, language/theme, feature toggles, local pattern data, app-lock/focus configuration, document files, edit history, and purchase entitlement cache on your device. Deleting the App usually removes sandbox data; items you exported to Photos or Files are not removed automatically.

6. In-App Purchases

Optional premium features are sold through Apple StoreKit. The current one-time non-consumable product ID is com.nickgao.lock.upgrade. Apple handles payment, taxes, and refunds. We do not receive your card number, full billing details, or Apple ID password. Any legacy subscription entitlements follow Apple’s records and in-app Restore Purchases.

7. Third Parties, Advertising, and Tracking

The App does not include third-party advertising SDKs, analytics SDKs, social-login SDKs, or cross-app tracking tools.

Per our privacy manifest and App Store privacy label, the App does not track you across apps or websites owned by other companies.

If you open the App Store, Photos, Files, Mail, or other system features, those services are governed by Apple’s or the third party’s own policies.

8. Sharing, Sale, and Disclosure

Because we do not collect personal data through routine App use, we do not sell or share personal information for cross-context behavioral advertising.

We may disclose information you voluntarily send only to respond to support, or when required by law, regulation, legal process, or governmental request.

9. Children’s Privacy

The App is intended for a general audience. We do not knowingly collect personal information from children under 13 through the App. If you believe a child sent us personal information by email, contact us and we will take reasonable steps to delete it.

Parents using the App to manage a device should ensure they are authorized to manage that device and account and comply with applicable law.

10. Your Choices and Rights

  • Revoke Screen Time, Camera, Photos, or Face ID permissions in Settings.
  • Turn off app lock, focus modes, or intruder detection, or reset local pattern credentials in the App.
  • Delete document-library items, cutout history, intruder captures, and any exports in Photos or Files.
  • Delete the App to clear sandbox data.
  • Ask us to delete information you previously sent by email.

Depending on where you live, you may have rights under laws such as GDPR, CCPA, or China’s Personal Information Protection Law. Because routine operation does not upload personal data to us, many access requests may not apply; we will still try to help with reasonable requests related to support correspondence.

11. Security

We rely on reasonable on-device protections (system file protection, sandboxing, system biometrics). No local tool can guarantee absolute security. Use a device passcode, keep iOS updated, and protect your pattern. Risks from lost devices, jailbreaks, shared credentials, or system vulnerabilities remain your responsibility to assess.

12. Changes to This Policy

We may update this Privacy Policy when the App, our practices, or legal requirements change. The effective date at the top shows the latest version. Continued use after an update means you acknowledge the revised policy.
