Is Bitmoji safe?
Bitmoji ships a hardcoded Snapchat OAuth2 client secret in its production bundle, enabling token-refresh impersonation.
The extension's background script contains a hardcoded OAuth2 client ID and client secret for Snapchat's token endpoint. These credentials are used in token-refresh requests to accounts.snapchat.com — any party who obtains the client secret alongside a user's refresh token can maintain indefinite Snapchat API access without the user's involvement. The secret is accompanied by a comment indicating it was approved for storage in the repository.

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

Where it sends data
Destinations our analysis observed Bitmoji 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.
