Windows · no telemetry · works offline
Luckycharms hangs a charm from the top of your screen on a rope that actually swings — seven point masses, Verlet integration, real gravity. It sits above every window and gets in the way of none of them.
That charm up there is live. Drag it · flick it · tap it to bless
An always-on-top overlay usually means an always-in-the-way overlay. Luckycharms works out where the charm and its rope actually are, every single frame, and stops taking clicks anywhere else — by rebuilding its own window region every frame. Clicks land on whatever is underneath.
Try it below: click the empty space and you hit the window behind. Click the charm and you catch it.
Click anywhere in the mock window
Every charm carries the place it comes from, what it is for, and the gesture that goes with it. Pick one and it swaps on the rope at the top of this page — cord, beads and all.
Nothing matches that.
Hanging a charm re-themes the cord from its own material list: bead colours come from the named materials, thread dashes, and metal thickens the strand.
Most charms pulse and scatter light when blessed. Four of them do something that belongs only to them. These are running the real animations — press one.
There is no main window and no taskbar button. Everything happens either on the charm itself or in the notification area.
Right-click the charm
Right-clicking the hanging charm opens a gallery of all thirteen, each with where it comes from and what it is for. Pick one and it swaps immediately. The last card is where you add a picture of your own.
Press Esc to close it without choosing.
Click the tray icon
The tray icon holds the things that are not about which charm you want. Double-clicking it performs the ritual without opening anything.
This menu is live — try it.
Point it at any picture. The background is cut away, the subject is cropped to fit, and the cord retints itself to the strongest colour it finds in your image.
It reads the colours around the border, floods inward from the edge so a shade that also appears inside the subject survives, feathers the cut by a pixel, then picks the accent from a 4096-bucket histogram. The tolerance is chosen by walking it upward and stopping just before the cut breaks into the subject — and you can overrule it. Your image never leaves this page. That is not a policy; there is nowhere for it to go.

Any image works. A PNG gives the best result — it can already carry a transparent edge, so there is less for the cut-out to guess at. A photo with a plain, even background is the next best thing.
—Chosen automatically by finding the point just before the cut breaks into the subject. Drag it lower if the subject is being eaten, higher if background is left behind.
Whatever you drop in is written back out as a PNG with a real alpha channel — a JPEG cannot carry the cut-out edge. Save it, then in the app right-click the charm, choose Add your own charm, and pick the file.
No. The window rebuilds its own shape every frame from the rope and the charm, so outside those few pixels the window is not there at all — clicks, drags and hovers land on whatever is underneath. It also hides itself when something goes fullscreen, so films and games are untouched.
Every package the Microsoft Store ships is signed by Microsoft and vetted before it is listed, so installing Luckycharms never puts you through the “Unknown Publisher” dialog or a SmartScreen reputation warning. Windows installs it, tracks it, and removes it cleanly — the same way it handles any other Store app.
What the app itself does, and does not do:
Right-click the charm itself. That opens the picker with all thirteen. The tray icon handles the rest — the ritual, launching at sign-in, and quitting.
Open Settings → Apps → Installed apps, find Luckycharms, and choose
Uninstall — or right-click it in the Start menu. Because it installs as
a Store package, Windows takes the whole thing with it: the app, your settings under
%LOCALAPPDATA%, the luckydangle:// handler, and the
launch-at-sign-in entry. There is nothing to clean up by hand and nothing left in the
registry.
The simulation stops when the rope stops. Once the charm settles, there is zero CPU activity until you touch it, scroll past it, or trigger a ritual. It also suspends rendering and hides itself automatically when fullscreen apps or games are active.
The overlay spans the whole virtual desktop rather than one screen, and the charm hangs near the right-hand edge of it.
Yes — the last card in the picker takes any PNG, JPEG or WebP. The background is removed and the subject cropped on your own machine, and the cord retints itself to the strongest colour in the image. You can try that exact process further up this page; it runs the same algorithm.
One payment, once. You are paying for a finished, signed, ready-to-run build — someone still has to build, sign, and support it. There is no subscription and nothing to cancel.
The purchase happens on the Microsoft Store, which shows you the price in your own currency before you commit. This site never sees a card field: it takes no payment, runs no checkout, and has nothing to compromise.
Luckycharms operates completely offline and makes zero network calls. The only IPC channel it opens is a local named pipe to coordinate single-instance status. No in-app account, no background telemetry, and no external tracking.
The Store puts it in place and keeps it current. It carries its own runtime, so there is nothing to fetch alongside it and zero third-party packages inside it.
Pauses when the screen is off, hides in fullscreen apps, and parks itself entirely once the rope stops moving.
A per-user link handler lets anything on your machine bless the charm or change it.
luckydangle://bless

Luckycharms installs from the Microsoft Store, so Windows handles the install, the
luckydangle:// handler, and every later update for you — and takes all
of it away cleanly if you uninstall. No administrator prompt, nothing machine-wide.
One payment, once. The Store shows the price in your own currency before you commit, takes the payment, and keeps the purchase attached to your Microsoft account — so it follows you to any PC you sign in to.
