Datadog's Session Replay provides granular control over what data is viewable during a session replay, allowing users to configure different privacy settings based on the context of a session replay and use case. The tool includes three obfuscation options: `mask`, `mask-user-input`, and `allow`, which can be configured on a per-page basis to determine how much detail to obfuscate in a replay. By default, Session Replay automatically masks all user inputs using the `mask-user-input` setting, but users can modify this setting through JavaScript RUM configuration or HTML attributes and classes. The `mask` option fully obscures text and input fields, while the `allow` option keeps all text and input fields visible, making it suitable for public-facing websites with minimal sensitive data. With Session Replay's privacy settings, users can review and analyze user behavior while keeping their data protected and meet security and compliance regulations.
