CAPTCHA Solving Data Privacy: What Gets Sent to CaptchaAI

Before integrating any third-party service, you should know exactly what data leaves your infrastructure. This guide catalogs every piece of data transmitted to CaptchaAI per CAPTCHA type, what the API does with it, and how to minimize data exposure.

Data Sent Per CAPTCHA Type

reCAPTCHA v2/v3

Not sent: Page content, user credentials, form data, browser screenshots, DOM content.

Cloudflare Turnstile

Image/OCR CAPTCHA

Important: The image body only contains the CAPTCHA challenge itself. It does not contain screenshots of your page, user data, or form fields — unless you accidentally include them.

What CaptchaAI Does Not Receive

CaptchaAI solvers never receive:

• Your login credentials for target sites
• Form field values (names, emails, passwords)
• Page content or DOM structure
• Browser history or local storage
• Files from your system
• Other API keys or tokens

The API is stateless — each request contains only the parameters you explicitly include.

Minimizing Data Exposure

1. Don't Send Unnecessary Parameters

Only include required parameters. Optional fields like cookies, userAgent, and proxy should only be sent when they improve solve rates for your specific target.

2. Use the Minimum Required pageurl

The pageurl tells CaptchaAI which domain the CAPTCHA is on. You can use the base domain instead of the full path:

• Full: https://example.com/account/login?ref=campaign123
• Minimal: https://example.com/account/login

Avoid including query parameters with tracking data or user identifiers.

3. Strip Sensitive Cookies

If you send cookies for better solve rates, filter out session tokens and authentication cookies. Only send cookies required by the CAPTCHA provider:

# Only send CAPTCHA-relevant cookies
captcha_cookies = {k: v for k, v in cookies.items()
                   if k.startswith("_g") or k.startswith("cf_")}

4. Use HTTPS (Default)

CaptchaAI's API endpoint (https://ocr.captchaai.com) uses TLS encryption. All data in transit is encrypted. Never downgrade to HTTP.

5. Rotate API Keys

If a key is compromised, it only grants access to your CaptchaAI balance — not to your target sites or data. Rotate keys periodically and revoke old ones.

Common Privacy Concerns

Compliance Considerations

For most CAPTCHA solving scenarios, the data transmitted is technical metadata (sitekeys, URLs, challenge images) — not personal data. However, audit logging helps demonstrate compliance.

Troubleshooting

FAQ

Does CaptchaAI use my data to train AI models?

CaptchaAI processes CAPTCHA challenges to return solutions. Specific data retention and usage policies are available in their terms of service.

Can I use CaptchaAI without sending a proxy?

Yes. Many CAPTCHA types support proxyless solving. Only send a proxy when required for specific targets.

Is the API key the only authentication?

Yes. The API key authenticates your requests. Protect it like any other credential — use environment variables, Vault, or secrets management.
