The fact this is VC funded is a red flag. There’s no reason why such a simple tool needs VC-level funding, and as a consequence the VCs also won’t be happy with the (relatively) low revenue from a paid product compared to a scummy product that stalks users.
“We won’t sell your data” is just wishful thinking and we both know that. It’s only a matter of time before this turns malicious and starts spying on users or wasting their time for the sake of “engagement” (the very thing it’s designed to fight against).
