To provide a stable service, we may engage third-party providers to process necessary information, for example:

Cloud servers or data storage services
SMS verification services
Crash analysis and performance monitoring

We require these providers to process information according to our instructions, this Policy, and applicable laws and regulations, and not to use it for their own unrelated purposes.

We will not publicly disclose your personal information unless you separately consent or laws or regulations require it.

5. How we store your information

We retain your personal information for the time necessary to fulfill the purposes described in this Policy.

Logs, crash reports, and diagnostic information are retained for as long as needed for troubleshooting and security.
Where the law requires retention, we follow the legally required period.

When a retention period ends, or you delete information or your account, we will delete or anonymize the relevant information within a reasonable period, unless laws or regulations provide otherwise.

After account deletion, the relevant personal information will be deleted or anonymized within 15 working days, unless laws or regulations provide otherwise.

Encryption of data in transit
Server access controls
Account permission management
Classification and management of sensitive information
Audit logs
Security monitoring
Restrictions on employee or partner access
De-identification or anonymization where necessary

After account deletion, we will stop providing account-related services and delete or anonymize the relevant personal information in accordance with the law and this Policy.

8. Device permissions

LunaMood may request the following system permissions as needed for its features:

Notifications: to send period, logging, and self-care reminders.
Network access: for sign-in, data synchronization, content loading, and service connections.
Photo library: when you choose to change your avatar, to select a photo from the system photo library, crop it, and upload it.

You may decline a permission that is not necessary for a core feature. This may prevent the relevant feature from working, but does not affect other features.

Other than when you actively use the avatar selection feature, LunaMood does not read other images in your photo library. LunaMood does not currently proactively access your contacts, precise location, microphone, or camera. If related features are added in the future, we will use them after obtaining your authorization.

9. Cycle predictions, insights, and automated processing

LunaMood uses the period, physical, emotional, and self-care data you choose to record to generate cycle predictions, reminders, trend reviews, and insights.

These are for everyday logging and self-observation only. They do not constitute medical diagnoses, treatment recommendations, a basis for contraception, or other medical decisions.

If you experience unusual bleeding, severe pain, persistently irregular periods, pregnancy-related concerns, or other significant discomfort, promptly consult a qualified doctor.

10. Protection of minors

LunaMood is not specifically directed at children under 14.

If you are under 14, please use LunaMood with the consent and guidance of a parent or other guardian. We protect minors’ personal information as required by law.

11. Cross-border transfers

We do not currently transfer your personal information outside mainland China.
