About Fallegro

Fallegro is a musical physics game: you place the notes of a classical melody so that a ball bounces from one to the next and plays it, in time. It is free, it runs in a browser, and it is made by one person.

Who makes it

Fallegro is designed and developed by Germain Lecourtois, a developer in France, as a personal project published on a non-professional basis: no company, no advertising, nothing to buy. The legal details are on the legal notice.

The rules it holds itself to

• Nothing is sold, and nothing is shown that isn’t the game. No ads, no purchases, no “premium”.
• No tracker, no third-party request. Fonts, sounds and code are all served by fallegro.com itself. The privacy policy lists every piece of data the game keeps.
• A score is a fact, not a claim. The physics are deterministic and run identically in every browser and on the server. The game sends your construction, never your score; the server replays it and only ranks it if the result matches, bit for bit.
• The music belongs to everyone. Every work in the game is in the public domain, and every file used is credited below with its licence.
• Playing needs no account. An email address is only asked for if you want your progress on several devices, and is used for nothing else.
