+FTW app store distribution permission
+
+Additional permission under GNU AGPL version 3 section 7.
+
+App distribution services, such as the Apple App Store, TestFlight and
+Google Play, attach their own terms to every copy they deliver. Those terms
+may limit how a recipient can use, copy or install that copy, and the service
+may add technical measures such as encryption or signing. The GNU AGPL
+forbids further restrictions on recipients (section 10), so such terms can
+conflict with it.
+
+For the FTW code covered by this grant, the copyright holders permit you to
+convey this program, or a work based on it, in object code form through such
+a service, and to accept that service's terms, even where those terms would
+otherwise conflict with the GNU AGPL. This permission covers only the
+restrictions that come from the service's own terms and technical measures.
+
+All other conditions of the GNU AGPL remain in force. In particular:
+
+- Offer the Corresponding Source of the exact version you convey, under the
+  GNU AGPL and at no charge, outside the service and free of its terms.
+- Make the license text and that source offer reachable from within the
+  program.
+- Add no restrictions of your own beyond those the service imposes.
+- Provide the Installation Information that section 6 requires. You need not
+  provide your own signing keys, provisioning profiles or service account
+  credentials, as long as recipients can build the Corresponding Source and
+  install it on their own device with the platform's standard developer
+  tools.
+
+This permission grants no exception for proprietary modules, plugins or
+derivatives of FTW. Third-party code retains its own terms; this grant does
+not override them.
+
+If you modify this program, you may extend this permission to your version.
+As section 7 permits, you may also remove it from your copy. If you do so,
+the GNU AGPL applies without this permission.
