If you use the "My Flow" function, a random ID is generated by the Flow server and assigned to each client device. These IDs are used solely to enable pairing functionality between Opera desktop and mobile applications and persist only while your devices are connected to My Flow. Your data is protected with end-to-end encryption and we retain it only as long as you continue to use the feature. You can disconnect your devices from My Flow, and delete your data through the application's [Settings](https://help.opera.com/touch/my-flow/) menu.

### Crypto Wallet

Depending on your location, some Opera browsers may allow you to access a non-custodial crypto "wallet" offered by our affiliate, Blueboard Limited (an Opera Group company). Blueboard is the data controller for this feature, and [you can read their privacy statement here](https://legal.blueboard.pro/privacy). Opera does not act as a data controller for this feature, but may process some data in order to help the wallet to function in our apps.

### Usage Statistics

126
When you install an Opera application, a random installation ID is generated. We collect this identifier, as well as Machine ID, hardware specifications (model, release date, etc.), operating system, environment configuration, and feature usage data to improve our products and services. For example, we may use it to analyze how our users interact with our applications, or to determine the effectiveness of promotional campaigns, or to detect and debug problems. We have no practical way of using this information to identify you personally. We retain this usage data for up to three years. You can opt out of reporting extended statistics through the settings menu and choosing not to "Help Opera".
