Cookie Policy for Service 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.

We are a privacy-first service. We use only the smallest necessary number of cookies to help improve your experience of This cookie policy is part of Friendly Captcha GmbH’s privacy policy, and covers the use of cookies between your device and our site.

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.

This Privacy Policy is only valid for Service Users. Our end user solution does not use HTTP cookies and does not store any data in the browser’s persistent storage.

What is a cookie?

A cookie is a small piece of data that a website stores on your device when you visit, typically containing information about the website itself, a unique identifier that allows the site to recognize your web browser when you return, additional data that serves the purpose of the cookie, and the lifespan of the cookie itself.

Cookies are used to enable certain features (eg. logging in), to track site usage (eg. analytics), to store your user settings (eg. timezone, notification preferences), and to personalize your content (eg. advertising, language).

Cookies set by the website you are visiting are normally referred to as “first-party cookies”, and typically only track your activity on that particular site. Cookies set by other sites and companies (ie. third parties) are called “third-party cookies”, and can be used to track you on other websites that use the same third-party service.

Types of cookies and how we use them

Functional cookies

Functional cookies are crucial to your experience of a website, enabling core features like user logins, account management, security, language setting and payment processing.

We use only essential functional cookies to enable these functions on our website.

The following data is only stored in the browser’s session storage for the duration of the browser session and is essential for ensuring the security of the website: 

A session ID for user logins and account management (__Host-x-frc-session), a random session ID (frc_sid), the number of loads of the protection software modules (frc_sc), the number of requests and repeated connection attempts (frc_rc), and the solutions to the puzzles and their solution context (frc_sol). 

We do not place HTTP cookies and we do not store any data in the browser’s persistent storage.
