Description
RudyQ Shield is a privacy-first, self-hosted CAPTCHA designed for real humans.
Instead of classic math problems like “1 + 1 = ?”, it asks natural language number questions in the 0–9 range, for example:
- What is the number just before 5?
- What is the number between 7 and 9?
- Add one to 2. What is the result?
- Minus two from 5. What is the result?

- Protects WordPress login, registration, password recovery and comment forms

FAQ

Does it call any external service?

No. The plugin is fully functional under the GPL. There are no license keys, trial periods, usage quotas, or disabled modules.
