One click.New wallpaper.
Search, click, done. A 4.6 MB app that closes when you close it and leaves nothing running behind.
One license. Version 1.0.3, signed and notarised on macOS.

Measured, not estimated.
From the app's own README, taken on Apple silicon. The last one is not a measurement but a promise: closing the window ends the process.

Most wallpaper apps want an account,a subscription and a background process.This one wants a click.
Small on purpose.
It quits when you close it
No tray icon, no helper, no login item. Closing the window ends the process, which is the whole reason it can be trusted to sit on your machine.
Nothing is sent anywhere
No analytics, no telemetry. A license check runs against Spiral's validator on open. Wallhaven is reached only when you search or apply. On open the app may also ask GitHub once for a newer build — named in Settings and switchable off. Every request runs in the Rust core, not the webview.
It stays out of your disk
Thumbnails are cached locally with a 200 MB ceiling you can see in Settings. The wallpaper now on your desktop is kept; earlier full-size copies are removed.
It checks what it downloads
A file is validated as an image before it is written or applied, so a bad response cannot become your desktop.
Three clicks, no setup.
01
Search
Wallhaven, safe-for-work only, no API key and no sign-in. The source sits behind an interface so more can be added without rewriting the app.
02
Click the one you want
It downloads, it is checked, and it becomes your wallpaper. The app says what it is doing while it does it.
03
Close the window
That is the quit. Nothing survives it.
The things people ask.
Do I need an account?
No, and there is nowhere to make one. Wallhaven's safe-for-work search needs no key, so the app ships without one.
Does it run in the background?
No. There is no tray icon and no helper process. Closing the window quits the app, and that is a design decision rather than a missing feature.
Do I need a license?
Yes. Buy Spiral Collection once on Whop ($9.99), then paste the license key when the app asks. The source stays public; the shipped apps stay locked without a key.
Windows?
Yes, and it works. The Windows build is not code-signed, so SmartScreen will warn you the first time; the README walks through what you will see.
Can I add my own wallpaper source?
No. Wallhaven is the only source. Shipping another is a product decision, not a missing interface.
Does it support animated or live wallpapers?
No. Static images only, deliberately: a live wallpaper is a process that never stops, and this app's whole promise is that it stops.
Small,and out of the way.
Signed on macOS, and 4.6 MB. Version 1.0.3 is out now. Needs a Spiral Collection license key.
