I’d caution against your “free forever” offer. Most people tend to backtrack on it.

There’s one case where it gets super popular, or attacked by spammers/bots, and the site becomes more effort to operate publicly than you want to do for free.

In another case your girlfriend stops using it, as well as some family, and the continued maintenance over the years feels like it isn’t worth it (because there is always maintenance.)

Either way you might want to shut it down, and promising “forever” to users feels problematic when you’re not being finically incentivised to keep it running. With the financial incentives it’s much easier to pass the burden on to someone else if you can’t run it for whatever reason too.

Thanks for the feedback, I appreciate that you are looking out for me really.

My intention, the meaning of "forever free", is that I will provide the service for anyone and everyone that cannot self-host themselves, but of course, if I don't have money myself to rent a server, for example, and I have to shut the app down I would inform the people using it. This is more or less expected from a free app in my experience and there is a paragraph in the terms related to this, under "NO GUARANTEES"

What I want to say though is that I won't charge users for as long as the app lives, if the app dies for whatever reason I will try to inform users to export their data and find a better place I guess.
