Frequently asked questions
Does a clean scan mean my store has no accessibility problems?
No, and we will not tell you otherwise. Automated testing reliably detects roughly 30 to 40 percent of WCAG 2.1 AA criteria. A clean scan means we found no machine-detectable issues on the templates we tested. The rest needs a person, and the app tells you exactly which parts those are.
Is Mendvale an accessibility overlay or widget?
No. Overlays inject JavaScript that rewrites your storefront at runtime, and regulators and disabled users have both been clear about how well that works. Mendvale writes fixes to your product data at the source, after you approve them, and its optional theme embed adds only pure CSS and one additive element.
What can Mendvale actually fix?
Two things, honestly: missing image alt text, written into your product data after you approve each description, and a skip-to-content link if your theme lacks one. Everything else it finds, it explains with the exact location and a suggestion, because automatic fixes for contrast, labels, or ARIA require guessing what you meant, and a confident wrong guess is worse than an honest gap.
How is the alt text written?
A vision model drafts a description for each image with no alt text. Every draft sits in a review queue until you approve, edit, or reject it, one image at a time. There is no approve-everything button. Nothing reaches your store without a human decision.
Why can Mendvale find alt text problems other scanners miss?
Shopify themes render a blank alt field as a valid decorative image, which DOM scanners correctly pass. The most common accessibility failure on the web is invisible to the tools that inspect rendered HTML. We ask your product catalog directly through the Admin API, which is where the answer lives and where the fix has to be written back.
What does the free plan include?
The full storefront scan, the full catalog audit, every finding with its exact location, and five image descriptions a month. Finding problems is free, forever. Paid plans buy the labour: more descriptions written for you, the accessibility statement with its dated record, and weekly re-scans with alerts.
What happens to my data if I uninstall?
Shopify sends us a deletion request and everything we hold for your shop is erased in a single transaction: scans, findings, drafts, statements, preferences, and tokens. The details are in the privacy policy.
Does Mendvale see my customers or orders?
No. The app never requests customer or order permissions. Its access covers products, files, and reading themes, and nothing else.
