    What It Means For You

Smartlook can record user screen sessions, capturing how users interact with the app. User data is sent to five or more third-party companies.

    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.

    Positive Security Features

    • None identified in this version of the app.

    Areas for Improvement

    • User behavioral data and usage patterns are shared with a large number of third-party companies, with limited visibility into where that information ends up.
    • Smartlook's session recording means user on-screen interactions may be captured and sent to an external service while the app is in use.
    • Data collection controls are limited, making it difficult to restrict behavioral profiling or reduce what is shared with advertising and analytics partners.
