Do we have any assurance that you won't sell it again?

To be clear: I never owned workout.lol, I was just the main contributor.

For the sell process, like with any open-source project whether it's an NPM package or anything else, there are no absolute guarantees... that's just the nature of open ecosystems...

But I've built Workout.cool with transparency in mind, no hidden business model, and self-hostable.

Just what I can tell you is this :

I've been passionate about fitness my whole life let's say. I started sports at 3 years old, and I've been into strength training for over 15 years.

I didn't build this to make money. I built it because I genuinely care and because I see more and more people missing out on the benefits of training, often overwhelmed by complexity, closed ecosystems, or paywalled apps, including people close to me, like my sister.

Hope that my reply counts for something...
