These choices carry into every lesson too, so you only make them once.

Privacy & disclaimer
A practice tool, not a certification. Oh Sail is a game for learning
sailing concepts. It is a supplement, not a substitute, for qualified on-water
instruction and a certified course. Real boats, real weather and real
right-of-way carry real risk. Always sail under proper supervision.
Privacy. Anonymous and local by default. Your name and progress live in
this browser, and the game is fully playable without an account. To improve the
lessons we collect anonymous gameplay analytics (which lessons start and
finish, where hints fire); these never include your name or email, and we honor
your browser's Do Not Track setting. Beyond that, data leaves your device only
when you choose: an email if you opt in or sign in (your progress then syncs to
your account), messages you send us, or playtest data you share yourself.
