1.1 Scope of Application​

  1. This Privacy Policy applies only to your use of our services within Mainland China (excluding Hong Kong, Macau, and Taiwan). If multiple language versions conflict, the Simplified Chinese version prevails.

  2. Section headings are for readability and do not affect the interpretation of terms.

2. How We Collect and Use Personal Information​

To provide services, ensure security, and optimize user experience, CanJournals collects personal information in the following scenarios:

2.1 Registration and Login​

To use cloud storage features, you must register and log in. Currently, you can create an account via third-party platforms like WeChat. We collect relevant information solely to complete registration. Per "minimum necessity" principles under Chinese regulations, we do not require phone numbers or additional personal data. Browsing CanJournals' website does not require registration.

Third-Party Login: If you use a third-party account (e.g., WeChat) to log in, we collect your username, nickname, profile picture, and authentication details solely for login and security purposes. Refusing authorization will not affect basic app functionality.

2.2 Operations and Security​

To ensure stable and secure services, we collect:

2.2.1 Device and Log Information​

  • Device identifiers (IMEI, Android ID, MAC address), IP address, network type, OS version, and other technical data.

  • Account and transaction details to verify identity, detect fraud, and prevent security incidents.

  1. Account information.

  2. Journals, entries, tags, schedules, uploaded images.

  3. Saved templates and stickers.

  4. App settings (themes, colors, preferences).

Notes:

  • Synced data is private and not visible to other users.

2.4 Transactions​

For in-app purchases (e.g., premium features), we partner with third-party payment providers (WeChat Pay, Alipay). Payment processing may involve biometric verification. Review third-party privacy policies before use.

When submitting feedback, we collect contact details, communication records, and related information to address issues and improve services.

2.7 Customer Support​

To resolve inquiries, we may collect account details, contact information, and communication records.

2.8 Account Recovery​

Account recovery requires verification via the original third-party login (e.g., WeChat). Lost third-party accounts require official documentation for recovery.

We use cookies and similar technologies (e.g., access tokens) to:
