CalcSuite privacy policy
Calculator Suite (package com.sumclartech.calcsuite) is a set of calculators: scientific, loan and EMI, finance, programmer, statistics and algebra. It has no account, no sign-in and no server of its own. Everything you calculate is processed on your device.
Data on your device
The app stores the following in its private app storage. It is never uploaded by the app and is not included in cloud backups or device-to-device transfers.
- Calculator state: the expression you are typing, the last answer (Ans), the memory value, the DEG/RAD setting and the number of digits shown.
- History: up to the 200 most recent calculations you finished with the = key (expression, result and time). You can delete single entries or clear the whole history at any time.
- Saved items: results you chose to keep with the Save buttons (a name, the result text and the time), up to 300 items. You can rename and delete them.
- Home screen layout and theme: tile order, tile colours and light or dark mode.
The values you type into the loan, finance, programmer, statistics and equation tools are kept in memory only while the app is running so that they survive screen rotation. They are not written to storage unless you tap Save on a result.
If you tap Share, Copy or Save CSV, the app hands the text you chose to the app or file location you pick through Android's standard share sheet, clipboard or file picker. The app does not read any other files.
Summary of data handling
| Data | Where it goes |
|---|---|
| Calculations, history, saved items, memory, settings | Stored on your device only |
| Advertising ID, IP address, ad interactions, diagnostics | Collected by Google AdMob to show and measure ads |
| Anything else | Not collected |
Accuracy of results
Calculations are provided for information only. Loan, savings and investment results are estimates based on the numbers you enter and standard formulas; they are not financial advice and may differ from your lender's or bank's figures.
Advertising and consent
The app shows a banner advertisement on its Home screen only, never inside a calculator. Ads are served by Google AdMob. To serve and measure ads, Google may collect and use your device's advertising ID and other device identifiers, IP address (which can indicate approximate location), app interactions such as ad impressions and clicks, and diagnostic information such as crashes and performance data. Where the law requires it, the app asks for your consent with Google's User Messaging Platform before any ads load, and you can review or change your choice at any time under Customize → Ad privacy choices when it is offered. You can also reset or delete your advertising ID in Android settings (Settings → Privacy → Ads). See Google's advertising policies and Google's privacy policy. Google acts as an independent controller of the data it collects for advertising.
Apart from AdMob, Calculator Suite includes no analytics, crash-reporting or other third-party tracking software, and it does not sell your data.
Retention and deletion
Use Clear all in the History or Saved tabs, or the Clear inputs buttons, to remove stored items. Uninstalling the app removes everything it stored on your device. To remove data held by Google for advertising, use your Google account's ad settings.
Permissions
Calculator Suite asks for no runtime permissions. It does not use your camera, microphone, location, contacts, messages, call log, photos or files. The app's own code declares only INTERNET and ACCESS_NETWORK_STATE, which the advertising software needs to load ads and to check that a connection exists. All calculators work offline. The Google Mobile Ads SDK adds a few ordinary (non-dangerous) permissions of its own: the advertising ID (AD_ID), READ_BASIC_PHONE_STATE, WAKE_LOCK and FOREGROUND_SERVICE. None of these gives the app access to your contacts, messages, files, camera, microphone or precise location.
Children
Calculator Suite is not directed to children under 13 and its ad configuration is for adult audiences. If you believe a child has used the app, contact us at the address above.
Changes to this policy
If this policy changes, the new version will be published at the same address with a new date.
