Instead of tracking visitors or making them click traffic lights, it uses **proof- of-work**: the visitor’s browser solves a small computational challenge in the background, the moment they start filling in a form. Bots pay a CPU cost that makes mass abuse expensive; humans wait a fraction of a second and never see a puzzle. **Why site owners choose it** * **No personal data leaves the EU.** The service is hosted entirely in the EU. No US transfer, no CLOUD Act exposure. * **No cookies, no tracking.** Nothing to declare in your cookie banner for the captcha. * **Nothing to solve.** No image grids, no distorted text, nothing to click. Fully accessible by design. * **Free plan.** 10,000 verifications per month at no cost. **What this plugin protects** * Login form * Registration form * Lost-password form * Comment form (with an option to skip logged-in users) Each can be toggled individually on the settings page. **Setup takes two minutes** 1. Create a free sitekey and secret at [infopeak.io/captcha](https://infopeak.io/captcha) 2. Paste them into Settings InfoPeak Captcha 3. Done – the widget appears on your forms and verification happens automatically You can try the plugin first with the public test credentials `ipk_test_sitekey`/` ipk_test_secret` – they work on any domain and never count against a quota. ### External services This plugin relies on the InfoPeak Captcha service to do its job. The service is operated by InfoPeak and hosted entirely in the EU. It is used for two things: 1. **Loading the captcha widget.** The script `https://captcha.infopeak.io/infopeak- captcha.js` is loaded in the visitor’s browser on the pages where a protected form appears. The browser then requests a challenge and submits the solved proof of work. This sends the site’s public sitekey and the computed solution. No cookies are set and no visitor is tracked. 2. **Verifying submissions.** When a protected form is submitted, your server sends the captcha token together with your sitekey and secret to `https://captcha.infopeak. io/api/v1/pow/siteverify` and receives back whether the token is valid. Nothing about the visitor is included. No personal data about your visitors is stored by the service. See the [privacy policy](https://infopeak.io/privacy) and the [terms of service](https://infopeak.io/terms). ## Screenshots [⌊The settings page - sitekey, secret and per-form toggles.⌉⌊The settings page - sitekey, secret and per-form toggles.⌉[ The settings page – sitekey, secret and per-form toggles.

There is nothing to click and nothing to solve. ### What do my visitors actually see? A small box above the submit button showing the verification status, and a “Protected by InfoPeak” line underneath. It ticks itself off while the visitor is filling in the form. They never have to touch it. ### Is it GDPR-compliant? The service is hosted entirely in the EU, sets no cookies and does not track visitors. There is no data transfer to the US. ### Does it work with caching plugins? Yes. The widget is plain JavaScript loaded from captcha.infopeak.io and works on fully cached pages. ### What happens if the captcha service is unreachable? Verification fails closed: the protected form submission is rejected with an error message asking the visitor to try again. ### Does it support my language? The widget ships in 16 languages (English, German, French, Spanish, Italian, Dutch, Portuguese, Polish, Danish, Swedish, Norwegian, Finnish, Estonian, Czech, Romanian, Ukrainian) and picks the right one automatically from your site’s language. ### Is there a free plan? Yes – 10,000 verifications per month, free forever. Paid plans start at 500,000 per month. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “InfoPeak Captcha” is open source software.
