Privacy Policy

Smart Calculator Pro · Last updated 19 September 2026

1. Who this covers

This policy explains how the Android application Smart Calculator Pro (package com.holymanzion.calculator, "the app") handles information. The app is published by an independent developer, contactable at the address at the end of this page.

2. Information the app collects

None. The app does not collect, transmit, sell or share any personal information. Specifically, it does not gather:

• your name, email address, phone number or any account details;
• your location, contacts, photos, files or calendar;
• device identifiers, advertising IDs or usage analytics;
• crash reports or diagnostic telemetry.

3. Why it cannot send data anywhere

The app does not request the Android INTERNET permission. Without it the operating system blocks all network access, so the app is technically incapable of transmitting your data — this is enforced by Android, not merely promised here. You can verify this yourself in the app's permission list, which is empty.

4. What is stored on your device

The app saves a small amount of data locally so it behaves sensibly between sessions:

• Calculation history — the most recent 100 calculations;
• Preferences — your theme, angle mode, keypad and formatting choices.

This is held in the app's private storage area, which other apps cannot read. It never leaves your device through any action of this app. Clearing history in Settings, clearing the app's storage, or uninstalling the app removes it permanently.

5. Android backup

If you have Android's system backup switched on, Android may copy the app's settings and history to your own Google account as part of routine device backup. That transfer is performed by Android, not by this app, and is governed by Google's Privacy Policy. You can turn it off in your device's backup settings.

6. Third parties

There are none. The app contains no advertising, no analytics SDK, no crash reporting service, no social media integration and no third-party trackers of any kind.

7. Children

The app is suitable for all ages. Because it collects no information whatsoever, it collects none from children either, and complies with COPPA and similar rules by simply not gathering data.

8. Your rights

Data-protection laws such as the GDPR and CCPA give you rights to access, correct, export or delete personal data a company holds about you. No personal data about you is held, so there is nothing to disclose or erase on request. The locally stored history and settings described in section 4 are already entirely under your control.

9. Changes to this policy

If the app ever gains a feature that changes how data is handled, this policy will be updated and the date at the top revised before that version is released. Material changes will also be noted in the app's release notes.
