    Quick Verdict

    Best for: People who want messaging with no third-party tracking

    What It Means For You

    Messages and contacts are not shared with any advertising, analytics, or marketing companies. No third-party services receive user data. A small number of technical issues were identified, but user information stays entirely within the app.

    Method and Limitations

    Static analysis only. CITT reviewed the code of this build without running the app, so runtime behavior was not observed. The findings below describe the analyzed build and may not reflect server-side controls or later versions. CITT makes no determination about compliance with any law or platform policy; it reports what the artifacts contain and cites the published guidance so a reader can compare.
