Frequently Asked Questions
Unlike other solutions, that only have client-side code open, Private Captcha's backend code is also publicly available, making it easy to verify how user data is handled. Additionally, you can host Private Captcha on premises inside your own organization.
Private Captcha comes with many pre-built integrations for popular online platforms, such as WordPress, and packages for many popular programming languages (Javascript, Python, etc.). Additionally, our documentation provides detailed setup and migration guides and integration examples.
Private Captcha does not use any client-side tracking technologies like cookies and does not retain Personally Identifiable Information (PII) on its backend systems. As part of service operation, user data is anonymized and aggregated, making it impossible to track to any individual user.
Private Captcha is powered by exclusively European suppliers. If you want to ensure that no data is transferred to other countries due to geographic routing, you can also use our EU-only API endpoints.
The data we collect belongs to you. We do not collect PII and aggregated data we do collect is not shared with any third-parties. Outside of the hosting companies that own servers on which data is stored, no other vendor can access it.
Short answer is no. Our non-EU servers are API servers only without any data persistance (any data copies are temporary in memory only). Any servers that store (and/or replicate) data on disk, are within the EU only.
The Private Captcha widget offers two color themes (light and dark) and also allows to do lower-level customization, using CSS, ensuring seamless integration with your website. Additionally, you can hide the captcha widget altogether and make your custom UI integration, all while keeping security benefits.
