Privacy Policy

Last updated: February 10, 2026

Lagusion ("us", "we", or "our") operates the following services:

All of the above are collectively referred to as the "Services". This page informs you of our policies regarding the collection, use, and disclosure of Personal Information we receive from users of the Services.

We use your Personal Information only for providing and improving the Services. By using the Services, you agree to the collection and use of information in accordance with this policy.

Information Collection

Services with Login (Mobile App)

While using the Mobile App, we may ask you to provide us with certain personally identifiable information that can be used to contact or identify you. Personally identifiable information includes:

  • Email — obtained through Google Sign-In or manual input.
  • Name — obtained through Google Sign-In or manual input.
  • User ID — automatically generated based on your email address.

We collect this Personal Information to provide the core functionality of the Mobile App, namely:

  1. User authentication — to verify your identity and secure API access.
  2. Cloud Sync Highlight — to synchronize your hymnal highlights across your devices.

We do not use this information for any purposes other than those stated above.

Services without Login (Web App)

The Web App at play.lagusion.org does not require login and does not collect any personally identifiable information from users. We only collect Log Data as described in the following section.

Log Data

Like many application operators, we collect information that your device sends whenever you use the Services ("Log Data"). This applies to all Services, including the Web App that does not require login. This Log Data may include information such as your device's Internet Protocol ("IP") address, device type and version, the pages you visit, the time and date of your visit, the time spent on those pages, and other statistics. We may use third-party services such as Firebase, Google Analytics, and Cloudflare to collect, monitor, and analyze this data.

Security

The security of your Personal Information is important to us, but remember that no method of transmission over the Internet, or method of electronic storage, is 100% secure. While we strive to use commercially acceptable means to protect your Personal Information, we cannot guarantee its absolute security.

Third-Party Services

The Mobile App uses Google Sign-In to simplify the authentication process. When you sign in using your Google account, we only receive basic profile information (name and email) according to the permissions you grant. We recommend that you read Google's privacy policy to understand how your data is handled by Google.

The Web App does not use any third-party login services.

Data Deletion

For Mobile App users who have an account, you may request the deletion of your account and all your personal data at any time by contacting us through the contact information provided below. Once the request is received, we will delete your Personal Information from our systems within a reasonable time.

Changes to This Privacy Policy

This Privacy Policy is effective as of February 10, 2026 and will remain in effect except with respect to any changes in its provisions in the future, which will be in effect immediately after being posted on this page. We reserve the right to update or change our Privacy Policy at any time and you should check this Privacy Policy periodically. Your continued use of the Services after we post any modifications to the Privacy Policy on this page will constitute your acknowledgment of the modifications and your consent to abide and be bound by the modified Privacy Policy.
