## 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.
