TrustCaptcha Samples — GDPR-compliant, privacy-first CAPTCHA

Protect websites and apps against bots and spam with a privacy-first, EU-hosted CAPTCHA solution.

What is TrustCaptcha?

TrustCaptcha combines proof-of-work, an AI bot-score and custom security rules to stop automated bot abuse — without image marking or puzzles

Key perks:

• Privacy-friendly & GDPR-compliant – data processed exclusively in Europe
• No visual challenges – users never label images or solve quizzes
• Fully themable widget – matches any brand and design and improves your user flow
• Conversion-safe – near-zero user drop-off compared to legacy CAPTCHAs
