       <description>
         <p>Backups have arrived. Pick any installed app, choose whether to include its data and runtime, and Klia Store packs everything into a single portable archive you can restore later — on this machine or a new one. No terminal commands, no guesswork.</p>
         <p>You can now support Klia Store directly from the app: after a successful install, an optional "watch an ad to support" button opens a short ad in your browser. It's entirely optional and takes a few seconds — a small way to help keep the project going if you feel like it.</p>
