Terms of use
Last updated October 2026
The app
The Day Sail is a personal logbook for recording days aboard: notes, weather, maintenance, expenses, photos and engine hours. It is provided as a convenience for the captain's own records.
Not for navigation or safety
Weather forecasts, wind bands, water levels and alerts shown in the app come from public services and may be delayed, incomplete or wrong.
Never rely on this app for navigation, weather decisions or the safety of a vessel, its crew or its passengers. Always use official marine forecasts, charts and your own judgment.
Your account
Keep your sign-in details private. You are responsible for what is recorded under your account.
Do not record other people's personal details in the logbook beyond what you genuinely need for your own records.
Your content
You own everything you record. You can export it at any time and ask for your account and data to be deleted.
We may use anonymised, aggregated information (never your entries) to keep the service running and improve it.
Fair use
The app is provided as is, without warranties. We may update, pause or withdraw features, and we are not liable for losses arising from use of the app.
