Privacy Policy - Weight Controller

Last updated: April 23, 2026

Weight Controller respects your privacy. This Privacy Policy explains what data the app may collect, how that data is used, how long it may be retained, and how users can request deletion of their account and personal data.

1. Who We Are

This Privacy Policy applies to the Weight Controller Android application.

2. Data We May Collect

Depending on how you use the app, Weight Controller may collect the following categories of data:

• Account data, such as your email address, when you sign in or register through Firebase Authentication.
• Profile data, such as the information you provide in the app, for example your name and height.
• Health-related self-entered data, such as your weight records and related tracking entries that you manually save in the app.
• Diagnostics and crash data, such as technical information needed to detect errors and improve app stability.
• Analytics data, such as general app interaction information used to understand usage and improve the user experience.

3. How We Use Your Data

Your data may be used to:

• Create and manage your account.
• Store and display your personal weight tracking information.
• Synchronize your information across sessions or devices linked to your account.
• Maintain app security, prevent abuse, and troubleshoot technical issues.
• Analyze app performance and improve features, reliability, and user experience.

4. Data Storage and Service Providers

Data may be stored and processed using third-party services that are necessary for the app to function, including Google Firebase services such as Firebase Authentication, Cloud Firestore, Firebase Analytics, and Firebase Crashlytics.

These providers may process data on our behalf in accordance with their own terms and security standards.

5. Data Sharing

We do not sell your personal data. We only share data with service providers when it is necessary to operate, secure, maintain, or improve the app.

6. Data Retention

We retain your personal data only for as long as it is reasonably necessary to provide the app and its features, maintain your account, comply with legal obligations, resolve disputes, enforce agreements, and protect the app against fraud or abuse.

• Account and user-entered data may be kept while your account remains active.
• Analytics and crash information may be retained for a limited period as part of operational monitoring and app improvement.
• Backups or technical logs may remain for a limited period before they are automatically overwritten or deleted.

7. How to Request Deletion of Your Data

You may request deletion of your account and associated personal data at any time.

When a valid deletion request is received, we will take reasonable steps to delete or anonymize, as applicable:

• Your app account information.
• Your profile information stored for use in the app.
• Your weight entries and related user-generated records stored for the app.

Some information may be retained when required by law, for legitimate security purposes, for fraud prevention, to resolve disputes, or when retained temporarily in backups or technical logs.

8. Your Choices

You may choose not to provide certain information, but some app features may not work correctly without it. You may also contact us using the email above to ask questions about your data.

9. Security

We use reasonable technical and organizational measures to help protect personal data. However, no method of transmission over the Internet or electronic storage is completely secure.

10. Children's Privacy

Weight Controller is not intended for children unless expressly stated otherwise in the app listing. If you believe personal data has been provided by a child inappropriately, please contact us so we can review and delete it when appropriate.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we do, we will update the “Last updated” date on this page.
