Is MerchFlow for Merch by Amazon safe?

Low risk

MerchFlow for Merch by Amazon sends stored license keys and account identifiers to its analytics servers.

When its embedded app runs on Amazon Merch pages, the extension reads the stored license key, email or account ID, and Merch tier from local storage. It sends those values as PostHog identity and pageview data to e.merchflow.app, and also sends license and account status data to merchflow.app/api/ping.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
