Every picture, sound and tune in Melodyslide is made in code: the art is drawn live on a canvas, the instruments are synthesised in your browser, and all melodies are original. No stock art, samples or licensed music.
Built with TypeScript, Vite and Capacitor. QR codes by qrcode-generator (MIT).
Works offline. No accounts, no tracking.
Melodyslide by Three Thread Games keeps your progress on this device. If Android backup is on, your phone may also include it in your own Google backup; we never see it.
We do not collect personal data, run accounts, or use analytics in this build. The phone app makes no network requests (the web version only asks its own server whether a newer build exists). Save codes, Daily results and Sandbox codes are created on your device and only go where you copy or share them.
If we add rewarded ads or in-app purchases later, we will update this page and ask for any required consent before those features run.
