Welcome to the "That Day" App ("the App", "we", "us"). We value and protect your personal information and privacy. This Privacy Policy explains how we collect, use, store, share, and protect your information, as well as the rights you may exercise. By using the App, you indicate that you have read and agreed to this policy.
This App is provided and managed by independent developer Zhao Yang, who is responsible for personal information processing.
This App is intended for recording and reflection and does not constitute medical advice, diagnosis, or treatment services.
This policy applies to the personal information processing activities that occur when you use the "That Day" iOS client. If you access third-party websites or services (e.g., Apple, cloud service provider pages), their processing behavior is subject to their own privacy policies.
We only process information to the extent necessary to provide the features:
The purposes for which we process information include:
Under applicable law, we may process information based on:
You can withdraw relevant permissions at any time in the system settings. Withdrawal does not affect the lawfulness of processing based on consent before its withdrawal.
Information such as location, health, and biometrics is considered sensitive personal information in some jurisdictions. We only process such information within the scope of your authorization or as permitted by law, and we take higher-level protection measures.
We do not sell your personal information. We only share the minimum range of information in necessary scenarios:
We will use reasonable efforts to require relevant service providers to take appropriate security and confidentiality measures.
Since we may use global service providers, your information may be processed outside of your country/region. We will take necessary compliance measures (such as standard contractual clauses or other legal mechanisms) according to applicable laws.
We retain data according to the principle of data minimization:
Depending on the applicable laws in your region, you may have the following rights:
The App does not provide services to children under 13 (or the legal minimum age in your region). If you believe there has been processing of minor information without guardian consent, please contact us, and we will handle it as soon as possible.
We take industry-standard security measures to protect information, including but not limited to transmission encryption, access control, minimum privilege, and secure storage (e.g., Keychain). However, no system can guarantee absolute security.
We may update this policy due to feature changes or legal requirements. Significant changes will be notified via in-app prompts or other reasonable means. Continued use after the update indicates your acceptance of the updated policy.
To exercise your privacy rights, submit data access/correction/deletion requests, or inquire about privacy-related issues, please contact:

You may exercise rights of access, correction, deletion, restriction, objection, portability, etc., according to law, and may lodge a complaint with your local data protection regulator.
We do not sell personal information. You may request information, deletion, and correction according to law; where applicable, you can request to limit the use of sensitive information.
We follow the principles of lawfulness, legitimacy, and necessity in processing personal information. For sensitive information (e.g., location, health, biometrics), we take separate authorization and protection measures. You can request to view, copy, correct, delete, and withdraw consent according to law.
You can request confirmation of processing, access, correction, deletion, anonymization, and portability according to law.
