Privacy Policy

Last updated: 01 Aug 2026

1. Scope

This privacy policy covers the use of applications published on App Store.

2. Is personal information collected?

a) Information you provide directly

We collect information you provide when you email us or submit forms (in the app or on our website).

b) Automatically through the Services and device

The Services may automatically generate and collect Usage Information, Device Information, and persistent identifiers for purposes such as functionality, stability, security, and diagnostics.

c) Through service providers (third‑party SDKs)

We use third‑party service providers (such as Google Firebase Analytics) solely to support the internal operations of the Services (for example: analytics and diagnostics, crash reporting, performance monitoring, and security and integrity). Where these tools collect persistent identifiers (such as device identifiers or IP address), we use them only for the internal operations purposes described above, and not to contact a specific individual, for behavioral advertising, or to build a profile about a specific user.

We seek to ensure, through contractual terms and configuration controls where available, that these providers process information on our behalf, and are restricted from using the data for their own independent advertising or profiling purposes.

Relevant third‑party policies:

• Google Firebase Analytics Service Policy: https://firebase.google.com/support/privacy and https://policies.google.com/privacy

3. How We Use the Information We Collect?

We use the information we collect to:

• operate, maintain, enhance, and provide the Services and their features;

• personalize the on-device experience (e.g., multiple profiles and settings);

• understand usage trends and improve features, balance difficulty, and improve user experience;

• troubleshoot issues, improve stability, and fix crashes;

• protect users and the Services (security, fraud prevention, abuse prevention);

• comply with legal obligations.

4. Display advertising

When displaying ads in the application, user information may be automatically obtained by the ad display module provided by the ad distribution company.

For information on what to buy, what is the use and what is provided to a third party, please check the links of the ad serving company's privacy policy below.

AdMob (Google Inc.)

5. Security

We use reasonable administrative, technical, and organizational measures designed to protect information from unauthorized access, loss, misuse, or alteration. However, no internet transmission or electronic storage system can be guaranteed to be 100% secure. To the fullest extent permitted by applicable law, we are not responsible for unauthorized access or disclosure caused by unlawful acts of third parties or events beyond our reasonable control. You use the Services at your own risk.

6. Changes and Amendments

We reserve the right to modify this Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. Any updated version of this Policy will be effective upon posting unless otherwise specified.

We will not use Personal Information in a materially different way than described here without providing notice and, where required, obtaining consent.

7. Acceptance of This Policy

By accessing and using the Services, you acknowledge that you have read this Policy and agree to its terms. If you do not agree, please do not use the Services.
