Privacy Policy for End Users

Friendly Captcha protects websites and online services from spam and abuse. Using proof-of-work, our solution employs a fundamentally new approach to spam prevention and therefore does not depend on tracking users and exploiting personal data.

Your privacy is critically important to us. At Friendly Captcha, we have a few fundamental principles:

  • We are thoughtful about the information that we collect through the operation of our services.
  • We store information for only as long as we have a reason to keep it.
  • We aim to make it as simple as possible for you to keep control over your data.
  • We help protect you from overreaching government demands for your information.
  • We aim for full transparency on how we gather, use, and share information.

Below you will find privacy information for end users, which incorporates these principles.

Service Users are those who incorporate our service into their website.
End Users are individuals who interact with our service through the websites of our Service Users.

Friendly Captcha acts as a data processor when providing protection features. The Service User, as the data controller, is responsible for complying with the privacy obligations for its website.

The Service User provides the applicable privacy policy for end users for its specific use of Friendly Captcha on its website.

Privacy Information for End Users

Friendly Captcha is an innovative, privacy-friendly protection solution designed to make it more difficult for automated programs and scripts (“bots”) to use websites. Friendly Captcha thus protects websites from abuse. 

The Service User integrates program code from Friendly Captcha into certain areas of its website (e.g. in a contact form). This means that the visitor’s device connects to Friendly Captcha’s servers in the context of the protected area (e.g. when sending a contact form).

The visitor’s browser is sent a puzzle from Friendly Captcha. The complexity of the puzzle depends on various risk factors. The visitor’s device solves the puzzle using certain system resources and sends the solution to the Service User’s web server. The Service User’s server contacts the Friendly Captcha server via an interface and receives a response stating whether the puzzle has been solved correctly by the end device.

The visitor’s browser transfers connection data, environment data, interaction data and functional data to Friendly Captcha. Friendly Captcha analyzes this data and determines how probable it is that the visitor is a human user or a bot; it then transmits the result to the Service User.

Depending on this outcome, the Service User can deal with the access to its website or individual functions as human or potentially non-human.

For more information on data protection when using Friendly Captcha and on information processed in the end device, please visit the privacy policy of the Service User that implemented Friendly Captcha in their website.

All data will only be used to identify and deal with potential bots and risks as described above. The purpose of the processing is therefore to ensure the security and functionality of websites.

Friendly Captcha does not use the data to identify a natural person or for marketing purposes.

Friendly Captcha does not store personal data from the visitor. Data that may identify the visitor, such as IP addresses, are anonymized via one-way hashing.

Friendly Captcha does not use HTTP cookies and does not store any data in the browser’s persistent storage.
