Privacy Policy – Price & Margin Calculator
Effective date: April 28, 2026
This page explains how the Price & Margin Calculator app handles data. The app is designed as a practical tool for working with price calculations, margin, VAT, markup, and related business values, while keeping data collection to a minimum.
Information processed by the app
The app does not require account creation, registration, or sign-in. It does not ask users to provide personal details such as name, email address, phone number, postal address, or contact lists in order to use its core calculation features.
Values entered into calculations, such as prices, costs, VAT rates, or profit-related inputs, are processed locally on the user’s device for the purpose of providing the requested calculation results. Under normal use, this calculation data is not sent to the developer and is not stored on external servers just because the app is being used.
Advertising and third-party services
The app may display advertising provided by third-party services, especially Google AdMob. When advertising is enabled, those services may process certain technical information needed to deliver, measure, secure, and improve advertising content.
This may include information such as IP address, device identifiers, basic device and operating system data, diagnostic information, approximate location derived from IP address, and information about interactions with ads. Such information is processed by the relevant third-party provider under its own privacy rules rather than by the developer under a separate advertising database.
More information about Google’s privacy practices is available at Google Privacy Policy.
Permissions and sensitive access
The app does not use sensitive device permissions such as access to contacts, camera, microphone, precise GPS location, SMS, or device storage unless such access is explicitly required for a clearly described app feature. If a future version of the app changes how permissions are used, this policy may be updated accordingly.
Children, updates, and contact
The app is not specifically directed at children under the age of 13. This Privacy Policy may be updated in the future to reflect changes in the app, changes in third-party services, or legal requirements. The latest version will remain available with the app and on this website.
