Common questions
How do I upgrade to Pro?
Sign in, pick monthly or yearly, and checkout takes about a minute (Stripe handles the card; we never see it). You can also upgrade right where the gate lives: the Lived toggle on Rhythm. Every check-in you record free still counts, so Pro reads your rhythm from day one.
Where does my data live?
On your device first, which is why the app is instant and works offline. Sign in and it is also backed up to your account, encrypted in transit and at rest; only your signed-in account can read it. There is nothing for us to sell, and you can export a full copy to a file anytime from the Your data card in Settings.
Do I need an account?
No. Everything works without one. A free account adds the part a browser can’t promise: your history (sleep and check-ins) synced across devices automatically, plus your whole setup backed up, with a Google or email sign-in.
If I upgrade later, do I lose the history I logged for free?
No, the opposite. Every night and phase check-in you log keeps counting, so the day you upgrade, your lived wave is already there, built from everything you have recorded.
What about refunds?
A full refund within the first 14 days, no questions asked. Cancel anytime from the billing portal and Pro runs until the period you paid for ends. A subscription should feel worth keeping every month.
Is this medical advice?
No. BodyClock is educational. It maps well-studied rhythms without false precision, and it never diagnoses. For sleep disorders or health concerns, see a clinician.
Can I use it on two devices?
Yes. A free account keeps everything you log (sleep and check-ins) in sync across every device automatically. Pro also keeps your phases, routines, and settings in sync, so a change on your phone shows up on your laptop too.
