The honest FAQ.
Why €19.99 and not free?
Free tier covers tracking. The full agent system uses real compute and clinical-grade tuning. €19.99 is the price of one bad meal a month, and you cancel any time.
What if I don't have a wearable?
Apple Watch SE and an Oura ring are the two cheapest paths. We also accept manual RPE input for sessions and a weekly self-check-in. The agents work with what you give them.
Can I bring my own coach?
On Elite, yes. Coaches certified through Celf Labs can pair with you and read the dashboard. Or pick from our roster.
What happens to my data?
It's yours. We never sell it, we never advertise to you, and you can wipe everything in one click. Period.
