Privacy Policy
Last updated: November 23, 2025Introduction
Welcome to Savings Visualizer. We respect your privacy and are committed to protecting your personal data. This privacy policy applies to both our website and our mobile application.
Information We Collect
Personal Financial Data
The financial data you enter into our tools (such as starting balance, monthly contributions, and interest rates) is processed locally on your device. We do not transmit this data to our servers, nor do we store it in any database.
Web Version
When you visit our website, we use Google Firebase Analytics to collect anonymous usage data. This helps us understand how users interact with our site so we can improve it. This data may include:
- Device type and operating system
- Browser type
- Pages visited and duration of visit
- Approximate geographic location (country/city level)
We also use Local Storage on your browser to remember your preferred theme settings (light/dark mode).
Mobile Version
Our mobile application functions entirely locally on your device. While it generally does not integrate with third-party analytics services, we provide an option on the welcome screen to disable any potential anonymous usage data collection (such as Firebase Analytics) should it be implemented.
Third-Party Services
We use the following third-party services to provide functionality:
- Google Firebase (Web only): For hosting and analytics. You can review Google's privacy policy here.
- Google Fonts: Both the web and mobile versions may load fonts from Google servers.
Data Retention
Since we do not collect or store your personal financial data on our servers, there is no such data for us to retain. Analytics data collected via Google Firebase on the web version is retained according to Google's data retention policies.
Children's Privacy
Our services are not directed to individuals under the age of 13. We do not knowingly collect personal information from children under 13.
Changes to This Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
