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.
Alternative to Google reCAPTCHA
Private Captcha is an independent, GDPR-compliant CAPTCHA made in EU that works without legal overhead and user friction
Why switch
Break out of captcha prison
Captchas like this not only destroy web accessibility, but also punish users for wanting more privacy. Unknowingly users of these captchas help label datasets for AI models to large companies running them. Ironically all these efforts fail to stop bots due to services from 3rd world countries where cheap labor solves them for few cents a piece.

Frequently Asked Questions
On scale, bots exhibit different usage patterns and fingerprints statistics than real users. Detection of those patterns is part of the Private Captcha solution.
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 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.
