Frequently Asked Questions

What counts as a request?
A "request" refers to obtaining a new "puzzle" from our servers by the captcha widget. Note that, by default, captcha widget only obtains a new "puzzle" when the user starts filling out the form, so you don't pay for every page load.
Can I try Private Captcha before buying?
You can try Private Captcha for 14 days for free without a credit card. After the trial period, you would need to choose a plan to continue using Private Captcha.
Is there an additional charge for traffic spikes (tier limit violation)?
After your usage exceeds current tier's limit for two consecutive months in a row, you will be contacted by our support with an offer to upgrade to a higher tier. You will not be automatically charged for sudden spikes of traffic.
How easy it is to migrate from other providers?
Like many other CAPTCHA providers, Private Captcha offers an API specification compatible with Google reCAPTCHA, so migration only involves replacing API endpoints and client widget code.
What about cancellations and refunds?
You can cancel your subscription at any time. If you cancel, you can get a pro-rata refund for the unused part of your subscription.
What payment methods do you support?
Currently we support credit/debit cards, iDEAL, Bancontact and also PayPal, Google Pay, Apple Pay as payment methods for all our paid plans.
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.
