-by various image compressors.
 
 # API & CLI
 
-Squoosh now has [an API](https://github.com/GoogleChromeLabs/squoosh/tree/dev/libsquoosh) and [a CLI](https://github.com/GoogleChromeLabs/squoosh/tree/dev/cli) that allows you to compress many images at once.
+Squoosh has [an API](https://github.com/GoogleChromeLabs/squoosh/tree/dev/libsquoosh) and [a CLI](https://github.com/GoogleChromeLabs/squoosh/tree/dev/cli) to compress many images at once.
 
 # Privacy
 
-Google Analytics is used to record the following:
+Squoosh does not send your image to a server. All image compression processes locally.
 
-- [Basic visit data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
+However, Squoosh utilizes Google Analytics to collect the following:
-- Before and after image size once an image is downloaded. These values are rounded to the nearest
-  kilobyte.
-- If install is available, when Squoosh is installed, and what method was used to install Squoosh.
 
-Image compression is handled locally; no additional data is sent to the server.
+- [Basic visitor data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
+- The before and after image size value.
+- If Squoosh PWA, the type of Squoosh installation.
+- If Squoosh PWA, the installation time and date.
 
-# Building locally
