Is DeepL: AI translator and writing assistant safe?
DeepL transmits account identifiers and an installation UUID to a third-party A/B testing service on startup.
When the extension initializes, it builds a user profile containing the DeepL account ID, organization ID, and a stable installation UUID, then sends that profile to Statsig's servers for feature-flag evaluation. Subsequent events are logged to a second Statsig endpoint. This data sharing occurs regardless of whether the user actively uses the translator.
Part of this rating comes from analysis signals we haven't published as detailed findings yet.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 3 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.
