CosLog Privacy Policy

Effective Date: May 4, 2026

At CosLog, we value your privacy and are committed to protecting it.

1. Information We Collect

CosLog stores your cosplay project data, including project names, budgets, work-in-progress logs, and photos locally on your device. This data is not uploaded to our servers or shared with others unless you explicitly choose to export or share it.

CosLog also uses Firebase with Google Analytics to understand app usage and improve the service. Google Analytics for Firebase may collect app usage events, device information, app-instance identifiers, crash-related signals, and similar analytics data. This analytics data does not include the cosplay project content, photos, budgets, or logs that you store locally in the app.

2. Camera and Photo Access

CosLog requires permission to access your camera and photo gallery to provide its core functionality:

These permissions are used exclusively for project management features and are not used to collect, store, or share your personal data externally.

3. Advertising

This app displays advertisements provided by third-party partners such as Google AdMob. These partners may collect limited information (for example, your Advertising ID, device type, or approximate location) in order to deliver personalized or non-personalized ads.

You can learn more about how Google AdMob handles user data here: https://policies.google.com/technologies/ads

4. Analytics

We use Firebase and Google Analytics for Firebase to measure app performance, understand which features are used, diagnose issues, and improve CosLog. Analytics data is processed by Google according to Google's privacy and data processing terms.

You can learn more about Google Analytics for Firebase and Google's handling of analytics data here: https://firebase.google.com/docs/analytics and https://support.google.com/analytics/answer/6004245

5. Data Retention

CosLog does not store your project data, photos, or personal information on our servers. All data remains on your device. Any data processed by advertising networks or analytics providers is handled according to their privacy policies and retention settings.

6. Third-Party Services

CosLog uses Google AdMob for displaying advertisements and Firebase with Google Analytics for app analytics. We do not sell your personal data. These third-party services may collect and process limited device, advertising, and analytics data as described in their own privacy policies. For more information on how Google handles your data, please refer to Google's privacy policy.
