Privacy Policy

Overview

Tax Inclusive Price Calculator performs tax calculations locally on your device. The developer does not operate a server that receives the amounts you enter or your calculation results. The app uses Google Mobile Ads (AdMob) and may use platform purchase services, which process limited information as described below.

Last updated: August 5, 2026

Calculation Data and Local Storage

Amounts entered for calculations and the resulting tax values are processed on your device and are not sent to a server operated by the developer.

Recent calculation state may be held temporarily for features such as copying a result. App preferences, such as appearance settings, may be stored locally using the standard storage provided by iOS or Android.

Advertising

The app uses Google Mobile Ads (AdMob) to display advertising. The Google Mobile Ads SDK and its advertising partners may process device or advertising identifiers, IP and network information, ad requests, impressions, clicks, and diagnostic information.

This information may be used for ad delivery and measurement, security, and fraud prevention and, where the user has permitted it, personalized advertising or tracking. Consent and platform privacy controls are presented where required.

The advertising service does not receive the amounts you enter into the calculator from the developer.

Purchases

Supported versions may offer an optional purchase to remove advertisements. Purchases are processed by Apple or Google. The developer may receive purchase status and transaction identifiers needed to provide the purchased feature but does not receive your full payment card details.

Third-Party Services

Information processed by Apple, Google Play, Google AdMob, or their advertising partners is handled under the applicable provider policies:

• Apple Privacy Policy
• Google Privacy Policy
• How Google uses information from partner apps

Retention, Deletion, and Your Choices

• Deleting the app removes its locally stored calculation state and preferences from your device.
• You can manage tracking, ad personalization, and consent through the options provided by the app, operating system, and advertising provider where available.
• Advertising and store providers retain and delete information according to their own policies and privacy controls linked above.

The developer does not retain a server-side copy of your calculation inputs or results.

Age Ratings

At the time of this update, the iOS App Store rating is 18+ and the Google Play content rating is 3+. Ratings may vary by country or region and may change when platform rating systems are updated.

Policy Updates
