I’ve been using both extensions almost every day for more than a year without getting banned, but there is always a risk.
Since the code is running inside a real browser, it might be more stealth than command line tools, not really sure about that.
Original tidal-dl-ng had a delay option to wait between tracks downloads, maybe i’ll implement the same feature.

I’m afraid too but there are more and more people looking for these tools so let’s release them :)

Yes one Qobuz & one Tidal account shared between all users. Works fine with 30 days trials forever.
