Is Grammarly: AI Writing and Grammar Checker App safe?
Grammarly sends per-domain typing metrics to its own servers and routes behavioral events to the third-party marketing platform Iterable.
The extension tracks how long a user types on each website and how many characters they type, keyed to the domain name (e.g. mail.google.com). These metrics are sent hourly to extension.femetrics.grammarly.io. Separately, user interaction events — including a Grammarly-assigned user ID and campaign tracking data — are forwarded to api.iterable.com, a third-party marketing automation service.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 27 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.
