• to implement the freemium model,
• to gather cumulative geostatistics on a country level (using an anonymized IP address).

• generated unique ID of installation,
• anonymized IP to obtain geo-location on a country level.

• At first app launch after new installation, the unique installation ID is generated and stored on a handset (something like a cookie in a browser). The anonymized IP is also collected at backend during the first app launch.
• Each time app starts the installation ID is used in communication with the backend.

This is the minimal set of information we need to collect to implement a freemium model. As such these information are mandatory, and the Colouro app needs to collect them. The only way to prevent this collection is to not use the Colouro app.

Note that the installation ID is generated for each installation. It is not really meant to track a specific user. If you reinstall the application, you will get completely new installation ID.

Anonymous analytics help us:

• find and resolve problems quickly,
• provide best user experience as possible.

We use Google Analytics for Firebase as third-party service for analytics (data processor). We intentionally disable demographics data collection in this service to grant higher privacy standard.

At the moment of writing Google describes the collected personal data by Google analytics for Firebase in the following terms:

Online identifiers, including cookie identifiers, internet protocol addresses and device identifiers; client identifiers (source)

Let us explain the collection in a more human way. In short, the analytics collect the following:

• Device model info,
• Operating system version,
• Analytics events—these are just short records about events in the app like:
  • App start,
  • A screen appears (e.g. preview dialog).
  • Successful connection to preview module.

These data collected are essential for us to make sure the application is working correctly and to help us improve the user experience.
