Calendar Atlas Privacy Policy

Last Updated: 2026-03-27
Effective Date: 2026-03-27

Calendar Atlas (the "App") values and protects your privacy. This Privacy Policy explains how we collect, use, store, and protect your information, and what rights you may have. Please read this Policy carefully before using the App. By downloading, installing, or using the App, you acknowledge that you have read and agreed to this Policy.

1. Types of Information We Process

Based on current app features, we may process the following information:

1.1 Information You Provide

• Nickname (for personalized display);
• Avatar image file path (for local avatar display);
• Favorite and browsing history records (such as country code, date, and holiday name).

1.2 Device and App Information

To support configuration delivery and service stability, the App may process device/app technical information, such as:

• App version, build number, and bundle ID;
• iOS version and device model;
• Screen resolution;
• Device identifier (identifierForVendor) and related parameters used in configuration requests.

1.3 Network Request Information

When requesting remote configuration or extended content (e.g., third-party images/videos), necessary technical request data may be generated, such as request time, response status, and error codes.

2. How We Use Information

We process the above information mainly to:

1. Provide and maintain core features (holiday browsing, statistics, comparison, settings);
2. Save your personalization preferences (default country, week start day, date format, nickname, avatar, favorites, history);
3. Support product configuration and feature adaptation;
4. Improve service stability, troubleshoot issues, and mitigate security risks;
5. Comply with applicable laws and regulatory requirements.

3. Permissions

The App requests permissions only when you actively trigger related features:

1. Camera permission: to take a photo for avatar;
2. Photo library permission: to choose an image for avatar.

If you deny these permissions, most core features (such as offline holiday browsing) remain available.

4. Storage and Retention

1. Personalization data and records (e.g., nickname, avatar path, favorites, history, default country) are primarily stored locally on your device (e.g., SharedPreferences).
2. Local data is retained for the period necessary to fulfill feature purposes. You may clear certain records within the App, or uninstall the App to remove local data (subject to possible system-level cache behavior).
3. For data processed through network interactions, we retain information only for the shortest reasonable period necessary to achieve the stated purposes, unless otherwise required by law.

5. Third-Party Services and Data Sources

1. The App uses offline holiday snapshot data for core display (sourced from public holiday datasets).
2. The App may integrate third-party public content services (e.g., encyclopedia summaries, images/videos) for extended reading/viewing experience.
3. Third-party services are operated independently by their providers. Your access to such services may be governed by their own privacy policies. We recommend reviewing those policies.

6. How We Protect Information

We adopt reasonable technical and organizational measures to protect information against unauthorized access, disclosure, alteration, or loss, including but not limited to:

• Access control and data minimization;
• Security measures during transmission and service calls;
• Logging and anomaly monitoring;
• Regular security checks and remediation.

However, please understand that no internet environment is absolutely secure, and we cannot guarantee absolute security of any system.

7. Children's Privacy

If you are a minor, please read this Policy with your parent or legal guardian and obtain their guidance before using the App.

8. Your Rights

Subject to applicable laws, you may have the right to:

1. Access and correct relevant information;
2. Delete or clear certain local data (e.g., favorites, history, avatar);
3. Disable system permissions (e.g., camera/photo library);
4. Stop using the App (including by uninstalling it).

If you need assistance exercising your rights, please contact us using the contact details below.

9. Sharing, Transfer, and Public Disclosure

1. We do not sell your personal information to unrelated third parties.
2. We may share, transfer, or disclose necessary information only when legally permitted, including:
   • With your explicit consent;
   • As required by laws, regulations, judicial, or administrative authorities;
   • As necessary to protect users, the public, or our lawful rights and interests.

10. Cross-Border Data Transfer

If cross-border data transfer is required due to technical architecture or third-party services, we will implement necessary safeguards in accordance with applicable laws and regulations.

11. Policy Updates

We may update this Policy in response to business changes or legal/regulatory updates. The updated version will be published in the App or related pages. Continued use of the App after publication constitutes acceptance of the updated Policy.
