Neryn's store scanner

Neryn checks whether Shopify stores are ready for AI shopping assistants. If you saw NerynSignals or NerynApp in your logs, this page explains what it is and how to stop it.

What it reads

Public pages only: /robots.txt, /meta.json, /products.json, /sitemap.xml, /llms.txt, /.well-known/ucp, the home page and up to three product pages. It does not log in, fill in forms, add to cart or check out.

How it behaves

• It reads robots.txt first and skips anything that disallows it.
• It makes at most one request per second to a store.
• It names itself as NerynSignals/0.1 with a link to this page. NerynApp/0.1 reads only stores whose owners installed the Neryn app.
• It never sends emails or messages to stores.

What we keep

The store's public name, country and product count, the score, the issues we found, and the link to the store's contact page if its footer has one. We do not collect personal data.

How to opt out

Add this to your store's robots.txt:

User-agent: NerynSignals
Disallow: /

We check it before every scan. Until 12 Oct 2026 the scanner was called ZiraynSignals; a rule for that name still works. To ask a question or have your store's data removed, email hello@neryn.pro.
