-## Privacy Inbox
-
-The Inbox helps you keep track of new restricted data types as they are captured, quickly classify them, and build a data Inventory.
-
-Segment detects these fields by scanning data from your Web, Mobile, Server, and Cloud Event Sources to detect PII based on the [default PII matchers](#default-pii-matchers). New properties sent into Segment appear in the Inbox in realtime.
-
-When you view the Inbox, it displays every property that was sent into Segment from Web, Mobile, Server, and Cloud Event Sources for the past 7 days. ([Object Cloud Sources](/docs/connections/sources/#object-cloud-sources) and [Reverse ETL Sources](/docs/connections/sources/#reverse-etl-sources) do not appear in the Inbox at this time.)
-
-You can click a row in the Inbox to learn more about a field and where it was collected. The expanded view shows:
-
-- which events contain the field
-- which sources are sending the field
-- which matcher (and what type of matcher) detected the field
-- an example code snippet containing a payload that the field appears in

-To streamline the classification process, Segment pre-classifies the data in the
-Privacy Portal Inbox as **Red** (likely highly restricted data), **Yellow**
-(likely moderately restricted data), and **Green** (likely least restricted
-data). These colors indicate how restricted the data is for your business. You
-can also send and block data from flowing based on its color classification and
-how restricted it is.
-
-Segment makes recommendations about how a field should be classified using
-built-in PII matcher [detection](#privacy-detection), however, you can always
-update the classification in the Inbox based on your company's requirements.
-
-### Change a recommended classification
-
-You can update the classifications to suit your needs by clicking on the color
-dropdown menu to change. For example, you might manually change a field that
-does not contain personal information in your implementation from a "Yellow"
-classification to "Green."

-which is a central repository of all of the properties _you_ classified as Red,
-Yellow, and Green. Any time you send this field from a Web, Mobile, Server, or
-Cloud Event Source — whether from another Source or event type — the Privacy
-Portal automatically classifies it and adds it to the Inventory.
-
-Keep in mind that if you have any Privacy Controls configured to control how you route Red data into Segment,
-the classifications you create in the Inbox are forwarded on to those Controls.
-
-For example, if you have a Privacy Control set up to block **Red** data from your Android source, any new fields you classify in the Inbox as **Red** will be blocked from entering Segment from your Android source.

-## Privacy Inventory
-
-The Inventory is a central repository of all of the properties _you_ classified as Red, Yellow, and Green. Where the [Inbox](#privacy-inbox) shows new, unclassified data with Segment's _recommended_ classifications, the Inventory only contains data that you explicitly applied Classifications to.
-
-**The Inventory is intended to be a Single Source of Truth so you can answer common regulatory questions about the data you're sending through Segment, for example:**
-
-- What data am I sending into Segment, and how frequently?
-- How restricted is the data I'm sending through Segment?
-- Where is the data coming from, on a property-by-property level?
-- Where am I sending this data?
-- Who within my organization has access to each property within Segment?
-
-Once you've classified the fields as Red, Yellow, and Green in the Inbox, the classified fields appear in the Inventory. You can use the filter at the top left to filter down to specific categories of data (for example, Red data, data from a production environment, data from specific sources).

-sent from each Source it comes from. You can click the Events tab to see which

-data in the side sheet updates in realtime, and includes a limited historical

+### Understanding Classification types:
+
+**Red Classification**:
+Fields that are classified as 'Red' are masked for users that do not have PII Access enabled. These fields are also blocked if you have set Standard Controls under Privacy > Settings section.
+
+Keep in mind that if you have set Standard Controls to block fields from any of your sources, any new classifications you create in the Inbox will start to take affect immediately. For example, if you have a Privacy Control set up to block **Red** data from your Android source, any new fields you classify in the Inbox as **Red** will be blocked from entering Segment from your Android source.
+
+**Yellow Classification**:
+Fields that are classified as 'Yellow' are masked for users that do not have PII Access enabled. 
+
+**Green Classification**:
+Classifying a field as 'Green' does not have any impact on the behavior of masking of fields within the Segment App, it is only available for the housekeeping purposes.
+
+Once a field has been classified as "Yellow" or "Red", marking it "Green" will not make it visible for users that don't have PII access.
