Effective date: October 22, 2026
This policy explains how CalcMaster (“we,” “our,” or “the app”) handles information when you use CalcMaster – All-in-One Calculator.
1. Information We Collect
CalcMaster is designed to provide calculator and mathematical tools. The information processed depends on the features you use and the version of the app.
- Calculations and entries: Numbers, expressions, and other values you enter may be processed to perform calculations. If the app includes calculation history, favorites, or saved items, these may be stored locally on your device.
- Information you choose to provide: If a feature allows you to send feedback or contact us, we may receive the information you include in your message.
- Advertising data: If ads are enabled, advertising partners may process device identifiers, IP address, approximate location inferred from IP, ad interactions, diagnostics, and other information as described in their own privacy policies and consent prompts.
- Diagnostics: The app or its service providers may receive crash reports, performance information, and technical information needed to maintain reliability, if these services are enabled.
Do not enter passwords, payment card details, or other sensitive personal information into calculator fields.
2. How We Use Information
Information may be used to operate calculator features, save your preferences and history, display and measure advertisements, diagnose errors, improve performance, respond to support requests, and protect the app from abuse.
3. Local Storage
Some features may save calculation history, preferences, or other app data on your device. You may be able to clear this data from within the app or by clearing the app's storage in your device settings. Uninstalling the app may remove locally stored data.
4. Advertising and Third-Party Services
CalcMaster may use Google AdMob or other advertising providers to show ads. These providers may collect or receive information from your device to deliver, limit, personalize, and measure ads, subject to your region, consent choices, and the provider's settings.
Third-party services operate under their own policies. Review their policies for details about their data practices.
5. Sharing of Information
We do not sell your personal information. Information may be shared with service providers that help operate the app (such as advertising, analytics, or crash-reporting providers), when required by law, to protect rights and safety, or as part of a business transfer. The app's actual integrations determine which of these situations apply.
6. Data Retention and Security
Locally stored data generally remains on your device until you delete it or remove the app. Information handled by third-party providers is retained according to their policies. We take reasonable steps appropriate to the app to protect information, but no method of storage or transmission is completely secure.
7. Children's Privacy
CalcMaster is not intended to knowingly collect personal information from children. If you believe a child has provided personal information to us through a support channel, contact us so we can review the request. If the app is directed to children or is made available under a family/children category, this section and the app's advertising and data practices must be updated to meet applicable requirements before release.
8. Your Choices and Privacy Rights
Depending on your location, you may have rights to request access to, correction of, or deletion of personal information, or to object to or restrict certain processing. You can manage device permissions and, where available, advertising or consent preferences through your device settings or the app. Contact us to submit a privacy request.
9. International Data Transfers
Third-party service providers may process information in countries other than your own. Where applicable, providers are responsible for using legally required safeguards for international transfers.
10. Changes to This Policy
We may update this Privacy Policy when the app, its services, or legal requirements change. The revised policy will be published at this page with an updated effective date.
11. Contact Us
For privacy questions or requests, contact the app developer:
- Developer: CalcMaster Developer (replace with your legal name or business name)
- Email: wasims831@gmail.com (replace with your active support email)
Important before publishing: Review this policy against the exact app build. Remove statements about features or services you do not use, add any services you do use, replace the placeholder contact details, and ensure your Google Play Data safety disclosures match your actual data collection and sharing.
