Frequently Asked Questions

How does the freemium model work?

You get 10 free scans per month. The counter resets monthly. Upgrade to Pro ($12/month) for unlimited scans and exports to share with your team or stakeholders.

How do I get a Pro license?

Email hello@a11ylens.com with "A11y Lens Pro License" in the subject. We'll send you a license key and payment instructions ($12/month). Enter the key in Settings to activate Pro. Your license works on all your devices.

What's included in the exported reports?

Reports include all violation details, WCAG success criteria references, severity classifications, code snippets, and remediation instructions—formatted in clean HTML or PDF ready to share.

Does A11y Lens catch all accessibility issues?

No automated tool catches everything. A11y Lens finds common WCAG violations, but manual testing is still needed for complete accessibility coverage—especially for keyboard navigation, screen reader compatibility, and contextual issues.

Is my data collected or sent to a server?

No. A11y Lens runs entirely in your browser. Scans happen locally, and no data is sent to external servers. All reports are generated on your machine. Your privacy is protected.
