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.
Does Private Captcha share your data?
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.
Do you offer a signed DPA?
Our DPA is part of our Terms and is binding upon acceptance of those terms - when you create your account you have to accept it. If you require a formally signed separate copy for your records, please contact support and we will provide you a digital version for your countersignature.
Do you keep or replicate data copies on non-EU servers?
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.
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.
