Morse Code One

Terms of Use

Effective 12 Nov 2026.

These terms cover your use of the Morse Code One trainer at morsecodeone.com and its optional accounts, provided by Morse Code One LLC ("we", "us"). By using the trainer, you agree to them. Contact is by email only, at [email protected]. There is no postal address.

The trainer is free, and provided as is

Morse Code One is a free practice tool. It is provided "as is" and "as available," without warranties of any kind, express or implied, including warranties of accuracy, fitness for a particular purpose, and non-infringement. There is no promise that it will always be available, error-free, or that saved practice history will never be lost. Use Download my data (Settings, then Account) if you want your own copy of what the server stores.

Your account

Fair use

Please don't:

Accounts that do these things may be suspended or deleted. Sign-in and new Jeopardy rooms are rate-limited. The short-lived counter behind that limit is described in the Privacy Policy.

Your data

Your practice history belongs to you. It is used only as described in the Privacy Policy. Browser-only progress stays in that browser. Signing in is what copies practice, My Course, and settings to the server so another device can load them.

Online play

Jeopardy rooms are temporary. A room is deleted 2 hours after it was last used. Don't put anything in a room name or a chat message that you need kept.

Changes and ending the service

The trainer or accounts may change, be suspended, or stop at any time. If accounts are going to be shut down, the aim is to say so in the app in time for you to download your data first. These terms may be updated. The date at the top shows when they last changed, and continuing to use the trainer means you accept the updated terms.

Limitation of liability

To the fullest extent permitted by law, Morse Code One LLC won't be liable for any indirect, incidental, special, or consequential damages, or for any loss of data, arising from your use of the trainer. Because the trainer is free, total liability for any claim relating to it is limited to US $10.

Governing law

These terms are governed by the laws of the State of California, without regard to its conflict-of-laws rules.
