 # Data Policy
-Tldr; we currently collect data on which shortcuts are used to inform our product decisions. We don't collect any personal info.
+
+## How we collect data
+We’re use Google Analytics - out of the box without any major customization. To learn more about Google Analytics read this: https://developers.google.com/analytics/resources/concepts/gaConceptsTrackingOverview#howAnalyticsGetsData
+
+We use Google Analytics to track data when users install the Macro Chrome Extension, when users visit our website (https://usemacro.github.io/) or when users visit our page on the Chrome store (https://chrome.google.com/webstore/detail/macro/pgffhcglkcdpalkgpkkghpofcoibodak)
+
+Our code is open source, you can see how we collect data here: https://github.com/UseMacro/macro-chrome-extension/blob/master/chrome-extension/js/analytics.js
+
+## What data we collect
+We collect metadata that’s collected by default in Google Analytics, such as device and geolocation information. In addition, we track events including when shortcut data is loaded, which shortcuts are used and when the legend is rendered.
+
+Our code is open source, you can see which events we track by searching for “logEvent” in these files:

+
+## What we don’t collect
+Google Analytics strictly prohibits sending Personally Identifiable Information (PII). We don’t read any of your cookies. We don’t know your usage or installs of other Chrome extensions or other competing products.
+
+## How we use your data
+The data will only be analyzed post-aggregation. We will use the data to better understand user behavior and improve the product. We will use the data to fix issues that occur in our product. The data will be used to help prioritize future product decisions. We will use data to find which channels drive the most traffic.
+
+## How we will not use your data
+We respect all our user’s privacy. We don’t intend to sell the data for any purposes including marketing or advertising purposes. We will not use data for any marketing or advertising purposes. It is not a concerted effort by us to examine the data of any particular customer.
+
