Information Collected Automatically

When you access our Service, we may automatically collect information linked to your device, including:

• IP address, operating system and version, device type and language preference
• Information related to your behavior and activity while using our Service
• Technical and diagnostic information to maintain service reliability
• Advertising identifiers (such as Apple's IDFA), when you grant permission through your device settings, to measure advertising effectiveness

How We Use Information

We use the information we collect to provide you with the best possible Service and continually improve it over time. Specifically, we may use your information to:

• Provide the Service and related features

How We Generate Content

Our Service uses a combination of traditional Chinese calendar algorithms, curated cultural databases, and AI-assisted natural language processing to provide calendar information, festival details, and personalized readings. To generate personalized content, we use only non-identifying parameters (such as birth date, time, and gender). We do not send your name, email, account ID, or any other personally identifying information to third-party content providers.

Third-party providers used for content generation do not retain or use these inputs for training purposes.

How We Share Information

We do not sell your Personal Information to third parties, nor do we disclose Personal Information to third parties for targeted or cross-context behavioral marketing purposes.

We take your privacy seriously and may disclose Personal Information only as follows:

• To business partners and service providers: We share your Personal Information with our business partners, service providers, and subcontractors as required to offer you our Service, including:
  • Cloud hosting and infrastructure providers
  • Authentication and security service providers
  • Error monitoring and diagnostic services
  • Customer support and communication services

Data Shared with Apple for Refund Reviews

When you request a refund for an In-App Purchase through Apple, Apple may ask us to provide information about your use of the purchased content to assist with reviewing your refund request. This information may include:

• App session activity (number of sessions and total usage time)
• Account age (how long you have been a user)
• Purchase and refund history (aggregated dollar amounts, not individual transactions)
• Whether the purchased content was delivered and functioning properly
• Account status (active or terminated)

This data is shared only with Apple and only when you initiate a refund request. Apple uses this information solely to assist with reviewing your refund request, in accordance with Apple's Privacy Policy.

You can opt out of this data sharing at any time in the app's Settings. If you opt out, we will not share any consumption data with Apple when you request a refund. Opting out does not affect your ability to use the app or request refunds.

Third-Party Advertising Partners

We work with the following third-party advertising partners to measure the effectiveness of our advertising campaigns and to reach people who may be interested in our Service:

• Meta Platforms, Inc. (Facebook and Instagram) — Meta Privacy Policy
• TikTok Ltd. (a subsidiary of ByteDance Ltd.) — TikTok Privacy Policy

If you grant tracking permission

When you tap Allowon Apple's App Tracking Transparency prompt, we share the following with the partners listed above for the purpose of advertising attribution and audience building:

• Apple's Identifier for Advertisers (IDFA)
• App events such as installs, registrations, and purchases, tied to your IDFA for campaign measurement

If you deny tracking permission

When you tap Ask App Not to Track, no IDFA is shared with these partners. Only Apple-sanctioned aggregated signals transmitted through Apple's SKAdNetwork framework are used for privacy-preserving attribution. SKAdNetwork does not track individual users.

Changing your answer

You can revoke tracking permission at any time on your iPhone at Settings → Privacy & Security → Tracking → Yueliang. Turning tracking off stops IDFA sharing immediately.

If we add new advertising partners beyond the ones listed above, we will update this section before sharing data with them.
