At Nettra, your privacy is our top priority. This Privacy Policy explains how we handle your data when you use our offline-first personal finance and networth tracking application. We are committed to protecting your financial information and being transparent about our practices.
Offline-First Storage
Your financial data is stored locally on your device using IndexedDB. We do not collect, store, or have access to your financial information on our servers.
Your Google Sheets, Your Control
When you choose to sync with Google Sheets, data syncs directly to YOUR Google Drive. We never store your financial data on our servers.
No Third-Party Sharing
We do not sell, rent, or share your personal or financial information with third parties for marketing purposes.
1. Data Stored Locally on Your Device
The following data is stored locally in your browser's IndexedDB:
- Financial assets (accounts, balances, account types)
- Transaction records (income, expenses, transfers)
- Categories and subcategories
- Currency preferences
- Application settings
This data never leaves your device unless you explicitly choose to sync with Google Sheets.
2. Google Account Information (Optional)
If you choose to enable Google Sheets sync, we collect:
- Your Google account email address (for authentication)
- OAuth access tokens (stored locally, not on our servers)
- Google Sheets spreadsheet ID (stored locally)
3. Usage Analytics (Optional)
We use Vercel Analytics to understand how users interact with our app. This includes:
- Page views and navigation patterns
- Device type and browser information
- General usage statistics
Analytics data is anonymized and does not include any financial information.
Local Data: Used solely to provide the finance tracking functionality within the app. This data remains on your device.
Google Account Data: Used only to authenticate your Google account and sync your financial data to your personal Google Sheets.
Analytics Data: Used to improve app performance, fix bugs, and understand feature usage to prioritize development.
When you enable Google Sheets sync:
- We request limited permissions to create and edit spreadsheets in your Google Drive
- Your financial data is sent directly from your browser to Google's servers
- We do not store or access your financial data on our servers during this process
- The spreadsheet is created in YOUR Google Drive and remains under YOUR control
- You can disconnect or revoke access at any time

We implement the following security measures:
- Local Encryption: Your browser's built-in security encrypts data stored in IndexedDB
- HTTPS: All connections to our app use HTTPS encryption
- OAuth 2.0: Secure authentication with Google using industry-standard OAuth 2.0
- No Server Storage: We cannot access your data because we don't store it on our servers
- Client-Side Processing: All financial calculations and data processing happen on your device
Important: Because data is stored locally, clearing your browser data or cache will delete your local financial records. Always enable Google Sheets sync as a backup.
You have the right to:
