Calculator — Privacy Policy

Last updated: December 15, 2025
Simple, transparent explanation of how Calculator handles data.

Introduction

Calculator is an Android application developed by Daatar Infotech. This Privacy Policy explains what data Calculator collects (if any), how third-party services used by the app may collect data, and how you can contact us with questions.

Data collected by the app

Calculator itself does not collect personally identifiable information such as your name, email address, postal address, or other confidential personal data. The app's core features operate locally on your device.

Third‑party SDKs

Calculator integrates non‑proprietary third‑party SDKs to help with crash analytics and other optional capabilities. The table below lists the SDKs and the types of data they may collect.

SDK name Purpose Data collected
Firebase Analyze application crashes and ANR (Application Not Responding) situations Device model, OS version, stack traces and error messages (crash location). No user personal information is collected by the app itself.

For Firebase terms and privacy details, visit the official Firebase Terms of Service and Privacy pages.

Permissions requested

Calculator requests a small set of Android permissions to enable optional features. These permissions and their purposes are described below.

android.permission.VIBRATE
Used to provide vibration feedback when operating buttons.
android.permission.SYSTEM_OVERLAY_WINDOW
Used to provide floating window functionality.
com.google.android.gms.permission.AD_ID
Declared for integration with Google Play services and Firebase (does not imply personal data collection by the app itself).

Data storage & retention

Calculator does not store personal data on remote servers. Crash logs or analytics reported to third‑party services (e.g., Firebase) are retained according to those providers' policies. If you wish to request deletion of data held by third‑party services, please contact the relevant provider and/or the app maintainer (contact details below).

User rights

Depending on your jurisdiction, you may have the right to access, correct, or request deletion of data about you held by third‑party services. Because Calculator itself does not collect personal information, requests relating to personal data should be directed to the third‑party provider (for example, Firebase) or to the app maintainer listed below.

Security

The app follows common best practices for Android app security, but no method of transmission or storage is 100% secure. The maintainers are committed to promptly addressing security issues and will release updates as needed.

Changes to this policy

We may update this Privacy Policy from time to time. When changes are significant, a clear notice will be included in the app or on the project page. The "Last updated" date at the top reflects the most recent revision.
