Is AI Grammar Checker & Paraphraser – LanguageTool safe?
LanguageTool sends detailed usage telemetry to its analytics servers, including a persistent unique user ID and subscription and trial status.
On each session, the extension transmits analytics events to analytics.languagetoolplus.com containing a persistent unique identifier alongside information such as extension version, paid subscription status, login status, preferred languages, A/B test group assignments, and trial status. The tracker fires on every significant user action — including page views and feature interactions — building a longitudinal record of how each user engages with the extension. The extension does respect the browser's Do Not Track signal.

Shared hosts - 6 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.

Where it sends data
Destinations our analysis observed LanguageTool contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
