You can use a USB Connection to your computer to access the files on the Sigma without using the Sigma App. The files are stored as .fit files.

I have tested this with the Rox 11.1 Evo. I can’t verify this for other Sigma Computers but it’s probably the same for all of them I guess.

Sigma is a german Brand, they make modern cycling computers and you don’t need an account to use these devices as far as I know.

… just to save a webpage which they tell themselves they’ll read later (but probably won’t) …

I include myself in this

thanks for the info. i am planning to use my own domain with an mail provider instead of self-hosting an email server. Reason beeing that in case i want to change my mail provider, i just move my domain to a new service provider instead of having to change my mail adress everywhere.
