Privacy policy

1. Who we are

LYFoo develops Jadelilt: Mahjong Slide (the “App”) and operates this website. This policy explains information processed through the App, its analytics and advertising services, this website, and support correspondence. For privacy questions, contact 1312813372@qq.com.

The App can be played without creating an account. Game progress, settings, garden letters and collectibles are stored on your device. Local game storage is separate from information sent through the third-party services described below.

2. Information and purposes

• Device and network information: device model, operating system and app/SDK versions, language, time zone, network status, IP address, vendor identifiers (such as IDFV), and SDK-generated installation or device identifiers. These support service operation, analytics, attribution, advertising and fraud prevention.
• Usage and diagnostics: app launches, sessions, app activity, event times and duration, advertising button interactions, errors, crash information and performance information, depending on the SDK and features in use. These help us understand use and improve reliability.
• Advertising and attribution: ad requests, impressions, clicks, ad format and placement, advertising network, campaign attribution, creative identifiers, estimated ad revenue and country/region. MAX ad revenue is reported to Adjust and ThinkingData; attribution network information from Adjust is also used in ThinkingData analytics.
• Advertising identifier: IDFA may be processed when available under your iOS tracking authorization and applicable consent choices. SDK identifiers and IP-based coarse location may still be processed for permitted non-tracking purposes when IDFA is unavailable.
• Approximate location: advertising and analytics services may infer country, region or city from an IP address. This is different from precise GPS location.
• Support information: your email address and information you choose to send, such as your app version, device model, issue description and screenshots. We use these to respond and investigate.

We do not ask you to provide contacts, photos, microphone recordings, health information or precise GPS location for the core puzzle gameplay. Please avoid including sensitive information in support messages.

3. SDKs and service providers

Services may receive information directly from their embedded SDKs or through our reporting integrations. Processing depends on the active service, configuration, region and privacy choices.

We require providers processing information on our behalf to protect it consistently with this policy and applicable requirements, restrict use to authorized purposes, and apply appropriate safeguards. Advertising partners may also act independently under their own policies. Information may be disclosed where required by law or necessary to protect rights, safety or prevent fraud.

4. Permissions and your choices

Apple's App Tracking Transparency setting controls permission for tracking across other companies' apps and websites and access to IDFA. You can review it in iOS Settings → Privacy & Security → Tracking. Refusing tracking does not mean that all analytics, contextual ads or security processing stops.

Consent is required before processing where applicable law or platform rules require it. This policy itself is not a consent prompt, and merely reading it does not grant tracking permission.

You can request access, correction, deletion, a copy of your information, withdrawal of consent, or an objection/restriction by emailing 1312813372@qq.com. Where applicable, you may opt out of sale/sharing for targeted advertising. Advertising disclosures can fall within those legal definitions even without a monetary payment. Visit Privacy choices & data deletion for instructions and provider controls. A website visit or email request does not automatically change your device's SDK settings.

5. Retention and deletion

We keep information only for as long as needed for the stated purpose: local progress while retained on your device; support correspondence while resolving your request and maintaining necessary follow-up records; analytics, attribution and advertising information for service measurement, security and applicable reporting obligations. Retention depends on the type of information, its purpose, service-provider settings, and legal requirements.

When information is no longer needed, we delete or de-identify it. Valid deletion requests are applied to information we can identify and control and forwarded to relevant processors, subject to legal, security and fraud-prevention exceptions. If an exception applies, we explain it. Backup copies may remain until the normal backup cycle expires and are restricted from routine use.

Deleting the App may remove local progress but does not automatically delete records already received by service providers. Contact us to request server-side deletion; your device's backups may separately retain app data.

6. Regional rights and transfers

Depending on your location, you may have rights to access, correct, erase, obtain a portable copy, object to processing, restrict processing, withdraw consent or opt out of targeted advertising/sale/sharing. You may use an authorized representative where allowed, appeal a privacy decision by replying to us, or complain to your local data protection authority. We do not discriminate against you for exercising applicable privacy rights.

Where relevant, our legal bases are providing requested services, consent, legitimate interests in reliability/security and understanding service use where permitted, and compliance with legal obligations. Withdrawing consent does not invalidate earlier lawful processing.

Our providers operate internationally. Information may be processed outside your country, including in the United States, China, the European Union and other provider locations. Where required, transfers must use applicable safeguards such as contractual protections and appropriate transfer mechanisms.

7. Children

The App is a general-audience puzzle game and is not designed as a child-directed service. If you are a parent or guardian and believe a child has provided personal information without required authorization, contact 1312813372@qq.com. We will investigate and take appropriate deletion or restriction steps. Applicable local age and parental-consent requirements continue to apply.

8. Security and updates

We use reasonable technical and organizational measures to protect information, including encrypted transport where supported and access controls. No service can promise absolute security.

We may update this policy when services or practices change. The date above identifies the current version. We will provide further notice and obtain consent where required for material changes.
