Sansu Step Privacy Policy
Last updated: October 9, 2025
Introduction
This Privacy Policy explains how the mobile application "Sansu Step" (hereinafter "the App") handles user information. Please read this policy carefully before using the App.
1. Information We Collect
The App may collect the following information:
-
Information related to ad delivery (collected by third parties automatically)
The App uses Google AdMob to display ads. For ad delivery purposes, Google may automatically collect anonymized identifiers, such as the Advertising ID. This information is used to optimize ad display. -
Error information during app execution
For improving app stability, technical logs (such as stack traces) may be collected when a crash or error occurs. These logs do not contain any personally identifiable information.
※ The App itself does not collect or store any personally identifiable information such as name, email address, location, or unique device identifiers.
2. Purpose of Use
- To display and optimize advertisements
- To monitor app performance and analyze crashes or errors
- To improve the App based on the above information
3. Data Sharing and Third-Party Services
For ad delivery and error analysis, the App may share data with third-party services. Please refer to each service's privacy policies for details:
※ Shared information mainly consists of anonymized technical data or identifiers and does not include personally identifiable information.
4. Internet Connection
The App requires an internet connection to display ads and send error reports. No other external communication is performed.
5. Data Storage
Learning progress and settings within the App are stored only on the user's device and are not sent to external servers (except for ad-related data collection and technical logs for error reporting).
6. Child Use
The App is primarily designed for elementary school children and their parents/guardians. Children under 13 should use the App under parental supervision. Because advertisements are displayed, parents should ensure children do not accidentally click on ads.
7. Changes to This Privacy Policy
This Privacy Policy may be updated as necessary. Any updates will be announced on this page or within the App. Significant changes will be communicated prominently.
