+      <p>
+        Privacy risks can arise when this specification is used in
+        combination with other functionality or when used over time,
+        specifically with the risk of correlation of data and user
+        identification through fingerprinting. Web application developers
+        using these JavaScript APIs should consider how this information might
+        be correlated with other information and the privacy risks that might
+        be created. The potential risks of collection  of such data over a
+        longer period of time should also be considered.
+      </p>
+      <p>
+        Variations in implementation light level values as well as event firing
+        rates offer the possibility of fingerprinting to identify users.
+        Browser implementations may reduce the risk by limiting event rates
+        available to web application developers.
+      </p>
+      <p>
+        If the same JavaScript code using the API can be used simultaneously in
+        different window contexts on the same device it may be possible for
+        that code to correlate the user across those two contexts, creating
+        unanticipated tracking mechanisms.
+      </p>
+      <p>
+        Browser implementations should consider providing the user an
+        indication of when the sensor is used and allowing the user to disable
+        sensing.
+      </p>
+      <p>
+        Web application developers that use this specification should perform a
+        privacy assessment of their application taking all aspects of their
+        application into consideration.
+      </p>
+      <p>
+        The event defined in this specification is only fired in the
+        <a href="#dfn-top-level-browsing-context" class="internalDFN">top-level browsing context</a> to avoid the privacy risk of
+        sharing the information defined in this specification with contexts
+        unfamiliar to the user. For example, a mobile device will only fire
+        the event on the active tab, and not on the background tabs or
+        within iframes.

+      <h2>Security and privacy considerations</h2>
+      <p>
+        Privacy risks can arise when this specification is used in
+        combination with other functionality or when used over time,
+        specifically with the risk of correlation of data and user
+        identification through fingerprinting. Web application developers
+        using these JavaScript APIs should consider how this information might
+        be correlated with other information and the privacy risks that might
+        be created. The potential risks of collection  of such data over a
+        longer period of time should also be considered.
+      </p>
+      <p>
+        Variations in implementation light level values as well as event firing
+        rates offer the possibility of fingerprinting to identify users.
+        Browser implementations may reduce the risk by limiting event rates
+        available to web application developers.
+      </p>
+      <p>
+        If the same JavaScript code using the API can be used simultaneously in
+        different window contexts on the same device it may be possible for
+        that code to correlate the user across those two contexts, creating
+        unanticipated tracking mechanisms.
+      </p>
+      <p>
+        Browser implementations should consider providing the user an
+        indication of when the sensor is used and allowing the user to disable
+        sensing.
+      </p>
+      <p>
+        Web application developers that use this specification should perform a
+        privacy assessment of their application taking all aspects of their
+        application into consideration.
+      </p>
+      <p>
+        The event defined in this specification is only fired in the
+        <a>top-level browsing context</a> to avoid the privacy risk of
+        sharing the information defined in this specification with contexts
+        unfamiliar to the user. For example, a mobile device will only fire
+        the event on the active tab, and not on the background tabs or
+        within iframes.
