PRIVACY POLICY
Simple Calculator
================================================================================
App Name : Simple Calculator
Package : com.simplecalculator.scientific.calculator
Developer : RAMADHANI ENTERPRISE
Effective Date : 21 April 2024
Last Updated : 25 April 2026
--------------------------------------------------------------------------------
SHORT VERSION
--------------------------------------------------------------------------------
Your calculations and history stay on your device only. We do not collect the
numbers or expressions you enter. We use Google AdMob to show ads and Firebase
(Analytics & Crashlytics) to measure usage and diagnose crashes. These services
may collect device identifiers and basic usage data as described in full below.
================================================================================
1. WHAT INFORMATION THE APP ACCESSES ON YOUR DEVICE
================================================================================
1.1 Calculations and History
------------------------------
Calculations, calculation history, theme choices, and settings are saved locally
on your device using Android standard storage (SharedPreferences and app-private
storage). This data is never transmitted to us or to any third party.
Uninstalling the App removes all of it permanently.
1.2 Internet Connection
------------------------
The App requests the INTERNET permission solely so that the advertising,
analytics, and crash-reporting services listed in Section 3 can function. We do
not transmit your calculation content over the network under any circumstances.
================================================================================
2. INFORMATION WE DO NOT COLLECT
================================================================================
We want to be clear about what we never collect:
- Your name, email address, or phone number.
- Your contacts, SMS messages, camera, microphone, or files.
- Precise or approximate location data (beyond coarse IP-derived region
inferred by ad partners for ad delivery, as described in Section 3).
- Your calculation expressions or results — these never leave your device.
- We do not sell or rent personal information to any third party.
================================================================================
3. THIRD-PARTY SERVICES
================================================================================
The App integrates the following third-party services provided by Google LLC.
Each service may collect information as described in their own privacy policies.
We have no control over data collected directly by these services.
3.1 Google AdMob (Advertising)
--------------------------------
We use Google AdMob to display ads inside the App so that we can offer it free
of charge. AdMob may collect:
- Advertising ID — a resettable identifier that Android provides to apps.
- IP address and general (coarse) location inferred from IP address.
- Device information such as model, OS version, and language.
- Ad interaction data including ad impressions and clicks.
AdMob may serve personalized ads where you have consented, or non-personalized
ads otherwise. In regions that require consent (EEA, UK, Switzerland), the App
will display a Google User Messaging Platform (UMP) consent dialog on first
launch. You may change your choice at any time by resetting your Advertising ID
in Android Settings.

3.2 Firebase Analytics
------------------------
We use Firebase Analytics to understand how the App is used in aggregate, which
helps us improve features and fix problems. Firebase Analytics may collect:
- App instance ID.
- Advertising ID (where permitted by the user).
- Device information including model, OS version, language, and country.
- App interaction events such as screen views, sessions, and app open/close.
We do not receive or log the specific numbers or expressions you calculate.

3.3 Firebase Crashlytics
--------------------------
We use Firebase Crashlytics to detect and diagnose app crashes so we can fix
them quickly. Crashlytics may collect:
- Crash stack traces and device state at the time of a crash.
- Device model, OS version, screen orientation, available RAM and disk space.
- A randomly generated Crashlytics Installation UUID that is not linked to
your personal identity.
We do not log your calculation inputs in crash reports.

================================================================================
5. LEGAL BASIS FOR PROCESSING (GDPR / UK GDPR)
================================================================================
If you are located in the EEA, the UK, or Switzerland, we rely on the following
legal bases for processing personal data:
- Consent — for personalized advertising and any non-essential analytics
identifiers. Managed through the UMP consent dialog and Android Advertising
ID settings.
- Legitimate interests — for crash diagnostics, fraud prevention, and app
security and stability.
- Contract performance — to deliver the App functionality you have requested.
================================================================================
6. YOUR RIGHTS
================================================================================
Depending on where you live (EEA, UK under UK GDPR, California under CCPA/CPRA,
Brazil under LGPD, India under DPDP Act, or other applicable jurisdictions),
you may have the right to:
- Access, correct, or delete personal information we hold about you.
- Object to or restrict processing of your personal data.
- Withdraw consent at any time without affecting the lawfulness of prior
processing.
- Request data portability in a structured, machine-readable format.
- Lodge a complaint with your local data protection authority.
- Opt out of the sale or sharing of personal information (California
residents). Reset or delete your Advertising ID in Android Settings to
opt out of personalized advertising.
To exercise any of these rights, contact us using the details in Section 11.
We may need to verify your identity before processing your request.
================================================================================
7. CHILDREN'S PRIVACY
================================================================================
The App is intended for a general audience aged 13 and older. The App is not
directed to children under 13 (or under 16 in some jurisdictions), and we do
not knowingly collect personal information from children under these ages.
If you believe a child under the age of 13 has provided personal information in
connection with this App, please contact us immediately using the details in
Section 11 and we will take prompt steps to delete such information.
================================================================================
8. DATA RETENTION
================================================================================
- On-device data — calculation history, settings, and theme preferences are
kept on your device until you manually clear app data or uninstall the App.
- AdMob data — retained by Google for periods described in Google's privacy
documentation.
- Firebase Analytics data — typically retained for up to 14 months, subject
to Google's policies.
- Firebase Crashlytics data — typically retained for up to 90 days, subject
to Google's policies.
We do not control the retention periods applied by Google to data collected by
their services. Please refer to Google's own documentation for the most current
retention information.
================================================================================
9. DATA SECURITY
================================================================================
All network communications between the App and Google's services occur over
encrypted connections using HTTPS and TLS protocols. On-device data is protected
by Android's per-application sandboxing model, which prevents other apps from
accessing your data.
No method of electronic transmission or storage is 100% secure. While we apply
reasonable measures to protect your information, we cannot guarantee absolute
security.
================================================================================
10. CHANGES TO THIS POLICY
================================================================================
We may update this Privacy Policy from time to time to reflect changes in our
practices, legal requirements, or the services we use. When we make changes, we
will update the "Last Updated" date at the top of this document.
Material changes — such as adding new third-party services that collect
additional data — will be communicated on the Google Play Store listing page or
through a notice within the App before the changes take effect. Your continued
use of the App after an update constitutes acceptance of the revised policy.
