About installing any apps (on devices)

You must agree to the terms and conditions before using the app.

Terms and Conditions – Worldwide Helpdesk in 24 hours (all apps in the market)

Once you install any apps on any device, you must have permission to install on that.

• In some countries/regions, the parents may have a right to install the app on their children's phones, but they must let the target users (children) know about the installation.
• In some companies or organizations, the owner/manager can install apps on employees' phones, but they must inform their employees about the installations. That means the employees accept having those apps installed on their phones. This installation may be for testing, surveying mobile phones' behavior (like screentime app), or tracking GPS locations (for work).

Phones mean smartphones and devices.
