PRIVACY POLICY — All Unit Converter Calculator
Effective date: 29 June 2026
Last updated: 29 June 2026
App name: All Unit Converter Calculator
Developer: tph software bd
This Privacy Policy explains how the "All Unit Converter Calculator" mobile application (the "App", "we", "us" or "our") handles information when you use it. By downloading, installing or using the App, you agree to the practices described in this policy. If you do not agree, please do not use the App.
1. SUMMARY (THE SHORT VERSION)
• The App works fully offline for all conversions and the calculator.
• We do not ask you to sign in and we do not collect your name, email, phone number, contacts, photos or precise location.
• Your conversion and calculation history and your settings are stored only on your device.
• We show ads through Google AdMob. Google and its advertising partners may collect certain device and usage data (including an advertising identifier) to provide and measure ads. This is the only category of data shared with a third party.
• You can manage your ad-personalisation consent at any time from Settings → Manage ads consent.
2. INFORMATION WE COLLECT
(a) Information you provide: The App does not require an account and does not contain forms that ask for personal details, so we do not collect information you type for the purpose of identifying you. Values you enter to convert or calculate are processed on your device to produce a result and may be saved to your local on-device history.
(b) Information collected automatically by us: None. We (tph software bd) do not operate analytics servers and do not receive your personal data.
(c) Information collected by third-party advertising (Google AdMob): To serve and measure ads, Google and its partners may automatically collect and process:
• Device and connection information (device model, operating-system version, language, network/IP address);
• Advertising identifiers (such as the Android Advertising ID / AD_ID);
• Ad-interaction data (ad views, taps and approximate, coarse location derived from IP);
• Cookies or similar identifiers used for ad delivery, frequency capping and fraud prevention.
This processing is governed by Google's own privacy policy.
3. HOW INFORMATION IS USED
Information is used only to:
• Perform the unit conversions and calculations you request (on-device);
• Save your preferences (theme, decimal precision, digit grouping) and recent history on your device;
• Display and measure advertisements and limit how often you see them (by Google AdMob);
• Fetch live currency exchange rates if, and only if, you open the optional Currency Converter;
• Keep the App secure and prevent abuse/ad fraud.
We do not use your data for any other purpose and we do not sell your personal information.
4. DATA SHARING
We do not share your personal information with anyone, except that the advertising data described in Section 2(c) is collected and processed directly by Google AdMob and its partners to provide advertising services. We do not transmit your conversion values, calculation history or settings to us or to any third party.
5. ADVERTISING AND YOUR CHOICES
The App uses Google AdMob to display banner, interstitial and app-open ads.
• In the European Economic Area (EEA), the United Kingdom and Switzerland, the App uses Google's User Messaging Platform (UMP) consent management to request your consent before serving personalised ads.
• You can review or withdraw your consent at any time from Settings → Manage ads consent.
• You can also limit ad personalisation in your device settings: Settings → Google → Ads (you may reset or delete your Advertising ID).
Google AdMob / Google Privacy Policy: https://policies.google.com/privacy
How Google uses information from apps that use its services: https://policies.google.com/technologies/partner-sites
You can opt out of personalised advertising at: https://adssettings.google.com
6. PERMISSIONS WE REQUEST
• INTERNET and ACCESS_NETWORK_STATE — used only to (a) load ads and (b) fetch live currency exchange rates when you choose to use the Currency Converter.
• Advertising ID (AD_ID) and related Ad Services permissions — used by Google AdMob to deliver and measure ads.
The App does not request access to your contacts, camera, microphone, SMS, call logs, precise GPS location, files or storage.
7. CURRENCY CONVERTER (OPTIONAL, ONLINE)
If you open the Currency Converter, the App makes a network request to a public exchange-rate service to download current rates. Only the request needed to retrieve rates is made; no personal data about you is sent. The latest rates are cached on your device so the feature can work offline afterwards. Every other feature of the App works without internet.
8. DATA RETENTION AND DELETION
Your settings and history are stored in the App's private storage on your device. You can delete this data at any time by:
• Tapping Settings → Clear all history; or
• Clearing the App's storage from Android Settings → Apps → All Unit Converter Calculator → Storage; or
• Uninstalling the App, which removes all locally stored data.
Data collected by Google for advertising is retained and deleted in accordance with Google's policies; you can reset or delete your Advertising ID from your device settings.
9. DATA SECURITY
Information stored by the App stays in Android's sandboxed, private per-app storage and is not exposed to other apps. While no method of electronic storage is 100% secure, we rely on the security protections provided by the Android operating system.
10. CHILDREN'S PRIVACY
The App is intended for a general audience and is not directed to children under the age of 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided personal information, please contact the developer so we can take appropriate action.
11. INTERNATIONAL USERS AND YOUR RIGHTS
Depending on where you live (for example under the EU/UK GDPR or the California CCPA/CPRA), you may have rights to access, correct, delete or restrict the processing of your personal data, and to object to or withdraw consent for personalised advertising. Because we do not collect or store personal data about you ourselves, most requests relating to advertising data should be directed to Google. You can exercise advertising choices using the controls described in Section 5.
12. THIRD-PARTY SERVICES
The App includes the following third-party services, each governed by its own privacy policy:
• Google AdMob (advertising) — https://policies.google.com/privacy
• Google User Messaging Platform (consent) — https://policies.google.com/privacy
• Public exchange-rate API (optional currency feature) — used only to fetch rates.
13. CHANGES TO THIS POLICY
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above and, where appropriate, provide additional notice. Your continued use of the App after changes become effective constitutes acceptance of the updated policy.
14. CONTACT US
This App is developed and published by tph software bd. If you have any questions, concerns or requests regarding this Privacy Policy or your data, you can contact the developer through the "Contact developer" / developer details section on the App's Google Play Store listing.
