+  <p>Notify.gov is comprised of two applications both running on <a href="https://www.cloud.gov">cloud.gov</a>:</p>
+  <ul class="list">
+    <li>Admin, a Flask website running on the python_buildpack which hosts agency user-facing UI</li>
+    <li>API, a Flask application running on the python_buildpack hosting the Notify API</li>
+  </ul>
+
+  <p>Notify.gov utilizes several cloud.gov-provided services through Amazon Web Services (AWS):</p>
+  <ul class="list">
+    <li>AWS S3 buckets for temporary file storage</li>
+    <li>AWS Elasticache (Redis) for caching data and enqueueing background tasks</li>
+    <li>AWS RDS (PostgreSQL) for system data storage</li>
+  </ul>
+
+  <p>Notify.gov also provisions and uses two AWS services via a <a href="https://github.com/GSA/datagov-ssb">supplemental service broker</a>:</p>
+  <ul class="list">
+    <li><a href="https://aws.amazon.com/sns/">AWS SNS</a> for sending SMS messages</li>

+  <p>Currently, Notify.gov operates under a GSA <a href="https://www.gsa.gov/system/files/Lightweight-Security-Authorization-Process-%28LATO%29%20%5BCIO-IT-Security-14-68-Rev-7%5D%2009-17-2021docx%20%281%29.pdf">Lightweight Authority to Operate (LATO)</a>. This federal security authorization
+  process leverages security controls provided by National Institute of Standards and Technology (NIST). The process is

+
+  <h2 id="data">Data</h2>
+  <p>To send a message, agencies upload a spreadsheet of phone numbers and other necessary data from their existing data
+  management system. On Notify.gov, data is encrypted when it passes through the service and when it’s stored on the
+  service.</p>
+  <p>Notify.gov is not a system of record and as a result does not have a SORN. Agencies are responsible for managing their
+  data outside of Notify.gov.</p>
+  <ul class="list">
+    <li>Notify stores data within the cloud.gov-managed PostgreSQL database and <a href="https://cloud.gov/docs/services/s3/#encryption">S3 buckets</a>. The entire database is <a href="https://cloud.gov/docs/services/relational-database/#encryption">encrypted at
+    the disk level</a>.</li>
+    <li>Additionally, data is encrypted at the field level when it is stored in the database, using OpenSSL 3.0.8 via the Python
+    cryptography library. The implementation is available <a href="https://github.com/GSA/notifications-utils/blob/main/notifications_utils/clients/encryption/encryption_client.py">on GitHub</a>.</li>

+  <h2 id="data-retention">Data retention</h2>
+  <p>Any recipient data uploaded is only held for seven days; all personally identifiable information (PII) is deleted for
