1. Overview Numba (the "App") is a financial planning tool designed to help users model pensions, mortgages, and household budgets. Your privacy is our priority. This policy explains how we handle your data.
2. Data Collection (Local Storage Only) Numba is a local-first application. This means:
All financial data, salaries, pension values, and mortgage details you enter are stored locally on your device.
We do not use any external databases or cloud storage to store your financial planning data.
We do not have access to, nor do we collect, any of the financial information you input into the App.
3. Third-Party Services & Advertising We use Google AdMob to display advertisements within the App.
Google may use advertising identifiers (such as the Android Advertising ID) to serve personalized ads.
For users in the UK and European Economic Area (EEA), we provide a consent form to manage how your data is used for advertising in compliance with GDPR.
You can reset your advertising identifier via your Android device settings at any time.
4. Permissions
Internet Access: Required to serve advertisements and fetch updated tax/pension rule references.
Notifications: Used to provide optional alerts related to your financial goals.
5. Data Security Since your data resides only on your device, the security of your information depends on the security of your phone. We recommend using biometric or passcode locks on your device.
