Yofi

Yofi is a privacy-first expense tracking mobile app. Your financial data is stored locally on your device — we never see it.

Privacy Policy

Effective Date: July 8, 2026

Welcome to Yofi (“we,” “our,” or “us”). We are committed to protecting your privacy. This Privacy Policy explains how your information is collected, used, and disclosed by Yofi when you use our mobile application (the “App”).

By using Yofi, you agree to the data practices described in this policy. If you do not agree with these terms, please do not use the App.

1. Information We Collect

A. Information Stored Locally on Your Device

Yofi is designed with a privacy-first approach. Your primary financial data—including accounts, transactions, budgets, subscriptions, and categories—is stored locally on your device using an internal database. We do not transmit, collect, or store this financial data on our servers.

B. Information Collected Automatically

To help us improve the App and provide essential features, we use third-party services that automatically collect certain non-personal and analytical data:

  • Google Analytics for Firebase: We collect anonymous usage data (such as page views, button clicks, and app stability metrics) to understand how users interact with Yofi. This helps us identify bugs and improve user experience.
  • Firebase Cloud Messaging (FCM): We collect your device's unique push notification token to send you important alerts, such as subscription reminders.
  • Device Information: We may collect device-specific information such as operating system version, device model, and unique device identifiers necessary for crash reporting and analytics.

2. How We Use Your Information

We use the automatically collected information solely for the following purposes:

  • To deliver and maintain the functionality of the App (e.g., triggering push notifications).
  • To monitor and analyze trends, usage, and activities in connection with our App to improve functionality and user experience.
  • To detect, investigate, and prevent technical issues, crashes, or security incidents.

3. Third-Party Services

We use the following third-party services, which may collect and process data according to their own privacy policies:

We do not sell, rent, or share your personal information with third parties for marketing or advertising purposes.

4. Data Security

Because your financial data is stored locally on your device, the security of this data relies on your device's built-in security features (such as passcode, FaceID, or fingerprint locks). We highly recommend keeping these security features enabled.

The analytical data transmitted to our third-party services (Firebase) is encrypted in transit and stored securely according to industry standards.

5. Your Rights & Choices

  • Opt-out of Push Notifications: You can opt-out of receiving push notifications at any time by modifying the notification settings within your device's system settings.
  • Data Deletion: Because your financial data is stored locally, you can permanently delete it simply by uninstalling the Yofi app from your device.

6. Children's Privacy

Yofi is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have inadvertently received personal information from a child under 13, we will delete such information from our records.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy within the App or updating the “Effective Date” at the top of this document.
