    What It Means For You

    Usage data and activity are collected and shared with multiple third parties. Users have limited options to opt out of this data collection. Information about network activity may be passed to external services beyond user control.

    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.

    Privacy Concerns

    What Data is Collected

    The app collects data about network usage, connection behavior, and activity patterns during operation. This information is retained as part of the service's standard data practices.

    Third-Party Data Sharing

    The data the service collects about user activity is shared externally as part of its operation. Information about how users use the network may reach parties beyond the app itself, without clear opt-out options available.

    Understanding the Scores

    • Security: 87/100
    • Privacy: 22/100
    • Data Security: 92/100
    • Network Security: 90/100
    • Code Safety: 83/100
    • Data Collection: 18/100
    • Data Sharing: 20/100
    • User Control: 30/100

    Positive Security Features

    • Strong protections are in place for how user data is stored and handled within the app.
    • Network communications follow established security standards, reducing the risk of user data being intercepted in transit.
    • The app's code structure reflects consistent attention to safety in software design.

    Areas for Improvement

    • The app gathers a broad range of data about user network activity, going beyond what is needed for basic operation, and provides limited ways for users to reduce this collection.
    • Information about user activity is shared with parties outside user control, which limits the privacy protections users would expect from a private networking tool.
    • Users' ability to manage, limit, or delete data collected about them is restricted, leaving users with little practical control over their own information.
