Is HBO Max SubStyler: Customize subtitles [QVI] safe?
HBO Max SubStyler enables viewing-data sharing by default and sends Max profile and watch data to its servers.
On install the extension turns on a 'share insights' setting without asking. On Max/HBO Max pages it then reads the account's profile details (first name, username, region, profile ID) and continue-watching and viewing history, and posts them to servers outside Max. The options page describes this as anonymous viewing insights, and the store description mentions only subtitle styling.

Shared hosts - 1 hostname
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.
