Privacy Policy for FinCalc

Last updated: June 20, 2026

Introduction

FinCalc ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use the FinCalc mobile application (the "App").

The short version: We do not collect, store, or share any of your personal data. All your financial calculations and spending records stay on your device — we never see them.

We cannot access, modify, or delete your data because we never have it in the first place.
