Privacy Policy

1. Who we are

The operator of the App (“we,” “us”) is the publisher responsible for Lufe as distributed on supported mobile storefronts. For privacy requests, email lufe-yb@163.com.

2. Scope

This Policy applies to the App and information processed in connection with it. It does not govern third-party websites or services that we do not control (for example, Apple’s App Store checkout flow), which are covered by those parties’ policies.

3. Information we collect

We design Lufe to work primarily on your device. Depending on how you use the App and your device settings, categories may include:

3.1 Information you provide

• Text or notes you enter inside the App (for example, strategy labels or planning notes stored locally).
• Communications you send to us (for example, support emails), including your email address and message content.

3.2 Information collected automatically on the device

• App diagnostics and performance: crash logs or basic technical data may be available through platform tools (for example, Apple crash reports if you opt in at the system level).
• Usage context: gameplay-related data stored on-device to power scores, galleries, modes, and continuity between sessions.

3.3 Optional device permissions

• Camera and microphone: accessed only if you grant permission through the system prompt, for optional features such as future challenge-related captures or voice cues as described in the App. If you deny access, core puzzle play can still function without those permissions.
• App Tracking Transparency (ATT): on supported iOS versions, whether you allow cross-app tracking is determined by your response to Apple’s prompt. We do not control that system dialog.

3.4 Purchases

In-app purchases are processed by Apple. We do not receive your full payment card number. We may receive limited transaction or entitlement signals needed to deliver virtual currency or content inside the App, consistent with Apple’s APIs.

4. How we use information

We use information to:

• provide, maintain, and improve gameplay, progression, and App features;
• validate and deliver virtual items tied to legitimate storefront transactions;
• respond to support requests and legal obligations;
• protect security, integrity, and fairness of the App; and
• comply with applicable law and enforce our User Agreement.

We do not sell your personal information for money. We do not use your content to train generalized public AI models unless we separately disclose that practice and, where required, obtain consent.

5. Legal bases (where applicable)

In regions that require a legal basis (such as the European Economic Area or United Kingdom, if applicable to you), we rely on one or more of: performance of a contract (providing the App), legitimate interests (security, product improvement balanced against your rights), consent (where required for optional processing), and legal obligation.

6. Sharing and processors

We may share information with:

• Apple and other infrastructure providers strictly as needed to distribute the App, process payments, or operate device-level services you choose to use;
• Professional advisers (lawyers, auditors) under confidentiality obligations;
• Authorities when required by law or to protect rights, safety, and security.

We require service providers to use information only for instructed purposes and to implement appropriate safeguards.

7. Storage, security, retention

We use administrative, technical, and organizational measures appropriate to the risk. No method of storage or transmission is completely secure. We retain information only as long as needed for the purposes above, unless a longer period is required by law.

Much of your gameplay data remains on your device; uninstalling the App may delete local data unless the platform keeps residual backups outside our control.

8. International transfers

If you use the App from outside the country where our systems or providers operate, your information may be processed in other countries. Where required, we implement safeguards such as standard contractual clauses or equivalent mechanisms recognized in your region.

9. Your rights and choices

Depending on your location, you may have rights to access, correct, delete, export, restrict, or object to certain processing, and to withdraw consent where processing is consent-based. You may also lodge a complaint with a supervisory authority where that right exists.

To exercise rights, contact lufe-yb@163.com. We may need to verify your request. Apple provides separate controls for purchases, subscriptions, and device permissions.

10. California residents (CCPA / CPRA)

If you are a California resident, the California Consumer Privacy Act (CCPA), as amended by the California Privacy Rights Act (CPRA), may grant you rights regarding personal information, including to know, delete, and correct certain data, and to limit use of sensitive personal information (if we process such categories as defined by law).

We do not “sell” personal information as defined by the CCPA/CPRA, and we do not “share” personal information for cross-context behavioral advertising as a business practice in the App beyond what your device platform controls (such as ATT). If our practices change, we will update this Policy and provide legally required notices and links (for example, a “Do Not Sell or Share My Personal Information” link if applicable).

California’s “Shine the Light” law (Civil Code Section 1798.83) may grant California residents certain disclosure rights about personal information disclosed to third parties for direct marketing. We do not disclose personal information to third parties for their direct marketing purposes as traditionally described by that statute.

11. Canada (PIPEDA and provincial laws)

If you are in Canada, we handle personal information in accordance with the federal Personal Information Protection and Electronic Documents Act (PIPEDA), where applicable, and substantially similar provincial laws (for example, in Alberta, British Columbia, and Quebec), where they apply instead of PIPEDA.

You may request access to or correction of your personal information subject to legal exceptions. You may file a complaint with the Office of the Privacy Commissioner of Canada or your provincial privacy commissioner, as applicable.

12. Singapore (PDPA)

If you are in Singapore, we process personal data in line with the Personal Data Protection Act 2012 (PDPA), including obligations regarding consent, purpose limitation, accuracy, protection, and retention.

You may withdraw consent for optional processing where consent is the legal basis, subject to contractual and legal limits. You may contact us to access or correct your personal data or to inquire about our data protection practices.

13. Australia

If you are in Australia, we comply with the Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs) where they apply to us.

You may access or correct personal information we hold, subject to exceptions in the APPs. If you are not satisfied with our response, you may complain to the Office of the Australian Information Commissioner (OAIC).

Nothing in this Policy limits any non-excludable consumer guarantee or remedy under the Australian Consumer Law.

14. Children

The App is not directed to children under the age required by the storefront or local law for unsupervised data processing. We do not knowingly collect personal information from children in a manner prohibited by applicable child-privacy laws. If you believe a child has provided us information, contact us and we will take appropriate steps.

15. Changes

We may update this Policy from time to time. The effective date at the top will change, and for material updates we will provide additional notice where required (for example, in-app disclosure).
