Privacy policy

Summary: We use Plausible Analytics to collect basic visitor information (region of origin, type of device) for diagnostic purposes. Plausible is fully GDPR compliant and their servers are based in the EU. We do no share, sell or store any of your data. We also do not use cookies (at all!), because we don't track you or sell you ads, and we really dislike those pop-ups asking you for consent.

At Knowuro, we take privacy very seriously and are fully committed to complying with the GDPR and other privacy regulations.

In this policy we explain what data we collect, why, how we handle it and what your rights are.

As a visitor to the site

The privacy of our website visitors is very important to use, so we do not track anyone individually.

  • No personal information is collected
  • No information such as cookies is stored in the browser
  • No information is sold to third-parties
  • No information is shared with advertising companies
  • No information is mined and harvested for personal and behavioral trends
  • No information is monetized

We use the Plausible Analytics script to collect some anonymous usage data for statistical purposes. The goal is to track overall trends in our website traffic, not track individual visitors. All the data is in aggregate only. No personal data is collected. Examples of data collected include visit duration, device type, operation system used during the visit and others. You can see the full details in Plausible’s data policy.

Our guiding principle is to collect only what we need and that we will solely process this information to provide you with the service you signed up for.

We use a select number of trusted external service providers for certain service offerings. These service providers are carefully selected and meet high data protection, data privacy and security standards.

We only share information with them that is required for the services offered and we contractually bind them to keep any information we share with them as confidential and to process personal data only according to our instructions.
