Privacy Policy.
Last updated: April 2026
1. Local-First Architecture
FINCALCU is built with a local-first architecture. Your financial inputs, calculations, and records are stored directly in your browser using local storage. No personal financial data is transmitted or stored on external servers.
2. Data Ownership
You retain full ownership of all data generated within the platform. You may remove all stored data at any time by clearing your browser storage or using the reset function inside the application. Once removed, data cannot be recovered.
3. Analytics & Advertising
To support free access, the platform may use third-party services such as analytics and advertising providers. These services may collect anonymized usage data such as device type, browser information, and page interactions. No financial inputs are shared.
4. Security Model
Since all data remains on your device, security depends on your local environment. We recommend using updated browsers and secure devices when handling sensitive financial planning.
