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, progress and playtest
data live only in this browser, and the game is fully playable with nothing sent
anywhere. The only things that ever leave your device are ones you choose to
share: an email, if you opt in to save your progress, or playtest data you send or
copy yourself. No password, no sign-in required to sail.
