Frequently Asked Questions

How does Private Captcha technology work?
Instead of asking users to solve complex puzzles or track their behavior, Private Captcha solves an invisible cryptographic task in the background. The system automatically adjusts the task difficulty, ensuring smooth access for real users while making it too costly for bots to attempt. Cryptographic task provides equal security regardless of bot's intelligence level, making it effective even as AI technology improves. Which is hard to say about image/sound recognition tasks of other captchas.
How does Private Captcha tell bots and users apart?
On scale, bots exhibit different usage patterns and fingerprints statistics than real users. Detection of those patterns is part of the Private Captcha solution.
How does Private Captcha comply with data protection regulations like GDPR?
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.
Can we use Private Captcha if our compliance requires strict EU-only data sovereignty?
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.
How does Private Captcha improve user experience upon Google reCAPTCHA?
The Private Captcha widget offers better accessibility for website visitors, regardless of their cognitive abilities. Also, it is a more lightweight (17 vs 220 kB) solution that does not require cookie banners and therefore reduces friction of using the website.
