The "User Content" section of Samsung's user agreement. The text reads: USER CONTENT Some of our Services allow you to share things like comments, photos, messages, or documents with us or with other users. When you share content you own or have created, you continue to own any intellectual property rights in or to that content. However, to use your content in our Services, you need to grant us a license for any content that you create or upload using our Services. When you upload, transmit, create, post, display, or otherwise provide any information, materials, documents, media files, or other content on or through our Services, including Input and Output, as defined herein (collectively “User Content”), you grant us an irrevocable, unlimited, worldwide, royalty-free, and non-exclusive license to copy, reproduce, adapt, modify, edit, distribute, translate, publish, publicly perform, and publicly display such User Content (“User Content License”) to the full extent allowed by Applicable Law. We do our best to keep User Content safe, but we are not responsible if any of your User Content or other data is lost. You should keep local copies or make backups of User Content and other data.
This is exactly why, despite owning more than one #Samsung device, I *never* use Samsung "services", especially for my writing. And don't even get me started on "permissions". *Always* read the #PrivacyPolicy and #UserAgreement.
