Privacy

Chargle does not collect anything.

There is no analytics, no crash reporting service, no account and no update check. The app has no networking code in it at all, which is the only version of this promise that can actually be verified. The source is public, so you can go and look.

What it keeps, and where

Two files, both in %LOCALAPPDATA%\Chargle, both plain text you can open in Notepad.

• settings.json holds the choices you make in the app. The sound pack, the volume, the on-screen panel style and position, the theme, whether it runs at login, and the file paths if you have pointed it at your own audio. Nothing else goes in it.
• crash.log is only written if something goes wrong. It contains the time, the part of the app that failed and the .NET exception, so that a bug you hit can be described in an issue instead of guessed at. It is capped at 256 KB and it never leaves your machine. Delete it whenever you like.

If you add your own sound packs they live in %LOCALAPPDATA%\Chargle\Sounds and stay exactly where you put them.

The Store build is packaged, so Windows quietly redirects that folder into the app's own storage rather than the plain one. Same two files, same contents, and they are removed when you uninstall.

What it reads while it runs

All of this is asked of Windows in the moment, held in memory and then forgotten. None of it is written to disk and none of it is sent anywhere.

• Whether the charger is connected, and the battery percentage.
• Whether Windows currently says you should not be interrupted. That single answer covers a focus session, presentation mode and a full-screen app, and it is how Chargle knows to stay quiet.
• Your Windows accent colour and whether you use the light or dark theme, so the app and the panel match the rest of your desktop.
• The audio devices Windows offers, so it can play through the one you have selected as default.

The one thing it writes outside its own folder

When you switch on Run at login, the portable build adds a single value under HKCU\Software\Microsoft\Windows\CurrentVersion\Run pointing at the exe. Switching it off removes the value again. That is the whole of its footprint on the registry.

The Store build does not touch the registry at all. It registers a startup task with Windows instead, which is why that version also shows up under Startup apps in Settings and can be turned off from there.

Removing it

If you installed it from the Store, uninstall it the way you would any other app, from Installed apps in Settings. Everything it saved goes with it.

If you are running the portable build, quit from the tray menu, delete the folder you extracted, then delete %LOCALAPPDATA%\Chargle if you want the settings gone as well. There is no uninstaller because there was no installer, and nothing is left in the registry once Run at login is off.

This website

These are static pages hosted on GitHub Pages. There are no analytics, no cookies and no third party anything. The typefaces, the sound files and the scripts are all served from this same site, so loading the page does not tell any other company that you were here.

Your browser stores one thing, and only if you use the light and dark switch in the corner. It is the word light or dark in local storage, so the page opens the way you left it. Clearing your browser data removes it.

Two things sit outside that. GitHub serves these pages and keeps ordinary server logs of requests, in the way every web host does, which is covered by the GitHub Privacy Statement. And the buttons that get you the app lead off this site, either to the Microsoft Store or to GitHub Releases. What those two do with the visit is theirs to describe, under the Microsoft Privacy Statement and the GitHub one above.

Changes

If any of this stops being true the page will say so and the date below will change. Given that the whole point is an app which does not phone home, the likeliest change is this page getting shorter.

Asking about it

Open an issue on the repository. Questions about what the app does with your data are welcome, and can be answered by pointing at the line of code that does it.
