Scientific Calculator Classic (package com.ehappsbd.scientificcalculator) · Last updated: 10 October 2026
This policy explains what information the Scientific Calculator Classic app ("the app", "we") handles. The app is published by EH Apps BD.
Everything you type into the calculator — expressions, results, the replay history, stored variables (A–F, X, Y, M) and your mode settings — is saved only on your phone so it is still there next time you open the app. We do not upload, see or sell any of it. Uninstalling the app or clearing its data deletes it.
The app has no account, no sign-in and asks for no personal details.
The app is free and shows a banner advertisement provided by Google AdMob. To show and measure ads and to prevent fraud, the Google Mobile Ads SDK may collect and process:
Device identifiers such as the Android advertising ID
Approximate location derived from your IP address
App interaction, diagnostics and performance information (for example ad impressions, taps and crash logs)
Basic device information (model, operating system version, language)
This data is collected by Google, not by us, and is handled under Google's Privacy Policy. You can learn how Google uses information from apps at policies.google.com/technologies/partner-sites.
Consent: Where the law requires it (for example in the EEA, the UK, Switzerland and some US states), the app asks for your consent before personalised ads are shown, using Google's consent tool. You can change your choice at any time from the app menu (⋮ → Ad privacy settings).
Advertising ID: You can reset or delete your advertising ID, or opt out of ad personalisation, in your phone's Settings → Google → Ads (or Settings → Privacy → Ads).
The app uses the Internet and network-state permissions only to load ads. It does not access your contacts, photos, files, camera, microphone or precise location.
The app is not directed at children under 13 and we do not knowingly collect personal information from them.
Data sent by the Google Mobile Ads SDK is encrypted in transit. Data stored by the app stays in the app's private storage on your device.
If this policy changes, the updated version will be posted on this page with a new "Last updated" date.
