What this does
TRESSO is local-first. Your videos, your posting work and your Publishing Profiles live on this computer, and the logins that let TRESSO publish are saved here too, encrypted with a key protected by your computer's own security. Everything is in the TRESSO folder in your user data: %APPDATA%\TRESSO on Windows, ~/Library/Application Support/TRESSO on a Mac.
Good to know
When you add a video, TRESSO keeps its own copy in that folder, under videos. To open the folder, go to Settings > Help and Support and choose Open Data Folder. Treat it as TRESSO's working space: do not move, rename or delete files in it by hand. A scheduled post whose video has been removed is marked File missing and is not sent, and the posted folder is what lets you post a video again from Archive Vault. To stop a post, remove it from the Queue instead. If you deleted a video by mistake, restore it from the Recycle Bin (or put it back with the same name) and TRESSO picks it up again.
Videos take space. Go to Settings > Help and Support and find Storage. It shows how much TRESSO is using, how much of that is videos, how much is free on the disk, and the folder it uses. TRESSO checks that there is room before it converts a video, and when free space runs low - under 5 GB, or less than the posts due in the next seven days need - it shows a warning with Open Storage.
Remove unused files clears what no post needs: videos that are not scheduled and not part of any post, videos you removed from the queue, extra copies of published videos and leftover working files. TRESSO lists what it will remove and asks first. Scheduled, retrying and publishing posts are never touched, nothing is removed while a post is publishing, and your own original videos outside TRESSO are never touched. On Windows and Mac the files go to the Recycle Bin or Trash, so you can restore them; the space is freed when you empty it.
Published videos: when you add a video, TRESSO makes its own copy, so your posts still publish if you move or rename the original. With Automatic cleanup on, TRESSO deletes only that copy 30 days after every account in the post has finished publishing. You can change the number of days (at least 7) under Published videos in Settings > Help and Support. Automatic cleanup is on for new installs. If your TRESSO was using an earlier default, it now uses 30 days; a number of days you chose yourself stays as it is; and if you never turned it on, TRESSO asks you once. Remove old published videos does the same cleanup once, on request.
Your original video files are never touched: cleanup never moves, changes or deletes them. Deleting TRESSO's copy is permanent. The post, its links, its results and views, and its preview picture stay in the Archive. To post the same video again, select it again. If a post's preview picture was lost earlier, TRESSO fetches it back from the platform: from YouTube, Bluesky and TikTok's public pages, and from Instagram, Facebook and Pinterest through your connection.
Deleting a post from the Archive removes TRESSO's copies of its video too.
Your media leaves this computer when you publish it, and it goes to the destination you chose - not to TRESSO. There is no TRESSO cloud holding your videos.
Some things do go to TRESSO's server: your licence check, the sign-in step when you connect an account (so app secrets never sit on your computer), update checks, the status Mobile Access shows on your phone and the retry or stop requests your phone sends to this computer, if you turn it on, and diagnostics only if you choose to share them. Your videos, captions and queue are not sent to TRESSO.
Because the work is local, scheduled publishing needs this computer to be on and the Scheduler to be running.
