Yes. It costs nothing, has no adverts, no trial period and doesn't need an account. SakuDesk Premium, a monthly subscription, unlocks more, but the free one keeps working on its own.

Windows 10 or Windows 11, 64-bit. It's built and tested on Windows 10. There's no version for macOS, Linux, phones or tablets.

No. SakuDesk Free is a single file with everything inside it. Download it, double-click it, and it runs. There's no installer and nothing else to set up.

Anywhere you like. A folder such as Documents\Apps is better than Downloads, so it doesn't get cleaned away by accident. If you turn on start with Windows, leave the file where it is afterwards, or turn the setting off and on again after moving it.

Windows shows that blue box for programs that aren't code-signed, which means it can't check who made them. SakuDesk Free isn't signed yet, so you'll see it. To carry on:

1. Click More info.
2. Check the file is named SakuDesk-Free.exe.
3. Click Run anyway.

Signing is a paid certificate renewed every year. Without it, the checksum is how you can be sure the file is ours.

Compare its SHA-256 checksum with the one on the download page. In the folder with the file, open PowerShell and run:

Get-FileHash .\SakuDesk-Free.exe

If the long code it prints matches ours exactly, the file is the one we published, byte for byte.

New programs that aren't signed and that few people have run yet are sometimes treated with suspicion, especially ones packed into a single file. Check the checksum first. If it matches and you got the file from this site, it's ours. If it doesn't match, delete the file and download it again from here.

Not to PetalWorks. It only contacts a service when you use a feature that needs one, such as searching for wallpapers or showing lyrics. The privacy page lists each one and what it receives.

A short three-second opening plays over your desktop, then the main window appears on Home. Your wallpapers live in Pictures\SakuDesk wallpapers. Put pictures there, or find new ones from the Wallpapers page, and turn on the cycle to have them change on a timer.

It's built to stay out of the way. Choose Low, Medium or High under Settings to set how much your PC can spend on its animations, and Home shows how much it's using right now. Its opening stays away from full-screen games, and its hotkeys work while you play.

Print Screen changes the wallpaper, F9 starts or stops the wallpaper cycle, and F7 and F8 move between your sound outputs. They work from the tray and inside games. Choosing your own keys is part of the full version.

In %USERPROFILE%\.sakudesk_free, a folder in your Windows user folder. Paste that into File Explorer's address bar to open it. Settings → Open settings folder takes you there too.

1. If you turned on start with Windows, turn it off in Settings.
2. Close SakuDesk Free from its tray icon.
3. Delete SakuDesk-Free.exe, then the .sakudesk_free folder in your user folder.

Your wallpapers in Pictures\SakuDesk wallpapers stay unless you delete them too.

Live wallpapers that move to your music, desktop widgets, a Discord voice hub, two speakers playing as one, setup profiles, a wallpaper for each screen, your own hotkeys, every theme, and your settings following you to every PC you sign in on. Inside SakuDesk Free you'll see these with a small lock. The Premium page shows them unlocked.

SakuDesk Premium is a monthly subscription you can cancel any time. The Premium page shows its price in your currency, with tax, read straight from Paddle, who sell it for us. Until it opens, that page says it isn't on sale yet.

On your account page, press Manage your subscription. Premium stays until the end of the month you've paid for, and nothing more is charged. SakuDesk then goes back to Free the next time it starts, and keeps your settings in case you come back.

Not for SakuDesk Free. SakuDesk Premium goes with a PetalWorks account: you subscribe with it here, and sign in with it in SakuDesk. You can sign in with Google, Facebook, Discord or Microsoft, and connect more than one of them.

Sign in on your account page, choose Delete my account and confirm. It's removed straight away. More on the privacy page.
