Uninstalling Stratos takes two steps: remove the app, then, if you want a clean slate, remove your data. Removing the app leaves your settings, sign-in and flight history behind on purpose, so a reinstall picks up where you left off.
Before you uninstall, make sure you have no active or unsubmitted flight. Your local flight database lives in the data folder, and deleting it permanently discards any flight in progress or report still waiting to send. Finish and submit your flight first.

​
Remove the application

1

Quit Stratos

Right-click the Stratos icon in the system tray (bottom-right of the taskbar) and choose Quit. With Minimise to tray on (the default), closing the window isn’t enough: Stratos keeps running in the tray.
2

Uninstall

Open Settings → Apps → Installed apps, find Stratos, click the ⋯ menu and choose Uninstall. (You can also right-click Stratos in the Start menu and choose Uninstall.)The uninstaller removes the program from C:\Users\<You>\AppData\Local\Programs\Stratos and clears the update cache at C:\Users\<You>\AppData\Local\stratos-updater.
The uninstaller does not delete your personal data in the Roaming folder. To remove that too, follow Remove your data below.

​
Remove your data

These folders hold your settings, airline sign-in, local flight database, logs, the downloaded app core and your installed plugins. The app folder is named Stratos on every platform.
Open File Explorer, paste the path into the address bar, press Enter, and delete the folder.%APPDATA% expands to C:\Users\<You>\AppData\Roaming, so your data folder is C:\Users\<You>\AppData\Roaming\Stratos. The AppData folder is hidden by default, but pasting %APPDATA%\Stratos into the address bar gets you there anyway.

​
What’s in the data folder

For reference, here’s what Stratos keeps in its data folder: The folder also contains caches the app rebuilds on its own. You can safely delete the entire folder: Stratos makes a new one the next time it opens.
Keeping the data folder is the easy way to reinstall later without re-entering anything: your airline sign-in, settings and history come straight back. Only delete it for a completely fresh start, or if you’re removing Stratos for good.
