This Privacy Policy explains how the Calculator app
(package com.ezapp.calculator; "we", "our", or "us") collects, uses, and shares
information about you.
1. Information Collection
We do not require you to create an account or provide personal identification information (such
as name, email address, or phone number) to use the app.
On-device data: Your calculation history, tape, and all display and behaviour
settings (theme, accent colour, decimal places, angle unit, and similar preferences) are
stored only locally on your device. They are not transmitted to us. Clearing the app's data,
using the in-app "Clear history" option, or uninstalling the app permanently removes them.
Device information: Our third-party providers below may collect basic device
information (such as device model and OS version) and advertising identifiers.
2. Third-Party Services
The app uses the following third-party services, which may collect information used to identify
your device:
Google AdMob — displays the
advertising banner shown at the bottom of the app, mediating ads from several ad networks —
currently including Meta Audience Network — on our behalf. Google may collect advertising
identifiers (Android Advertising ID) and general usage data to serve, personalise, measure,
and limit fraud in ads. See also
How Google
uses information from sites or apps that use our services.
Meta Audience Network —
an AdMob mediation partner that may independently collect advertising identifiers and
app-usage data to serve and measure ads on our behalf.
Firebase Analytics —
collects anonymous, aggregated feature-usage data (such as which calculator mode is used) tied
to an anonymous app-install identifier, not your identity.
Firebase Crashlytics
— records crash and stability data (crash stack traces, device model, OS version, app state at
the time of a crash) so we can diagnose and fix defects.
3. Use of Information
Information is used to keep the app working and stable, to diagnose crashes, to understand which
features are used, and to show and measure advertisements in compliance with Google's policies. We
do not sell your personal information.
4. GDPR (European Users) & CCPA (US Users)
GDPR: Users in the EEA, UK, and Switzerland have the right to access,
correct, or delete their data. You can manage your consent for personalised ads through the
consent dialog shown by Google's advertising SDK, and you can reset or delete your advertising
ID in your device settings.
CCPA: We do not sell your personal information. You have the right to
opt out of data collection for advertising purposes via your device's ad settings.
5. Children's Privacy
The app is a general-audience utility and is not directed to children under 13. We do not
knowingly collect personal information from children.
6. Data Retention
Calculation history and settings are stored only on your device, so you control retention — use
"Clear history" in Settings, clear the app's data, or uninstall the app to remove everything it
stores locally. Data processed by Google (advertising, analytics, crash reporting) is retained and
managed according to Google's own policies linked above.
7. Changes to This Policy
This policy may be updated from time to time as the app changes. Material changes will be
reflected here with a new effective date.
