A CLEARER HISTORY
See your rhythm at a glance.
Log flow and daily check-ins, then look back across a calm, readable calendar designed around the information you actually need.
YOUR BODY, YOUR RHYTHM
A gentler way to understand your cycle.
Rhyvelle is a private cycle diary for periods, symptoms, moods, and the patterns that make you, you. No ads. No account. No judgement.
In development for iPhone and Android
MADE FOR REAL CYCLES
Your cycle is not a countdown clock.
Bodies change. Cycles vary. Rhyvelle helps you notice your own patterns without presenting estimates as certainties—or turning a deeply personal experience into a stream of ads.
CHECK IN, YOUR WAY
Track more than dates.
Capture mood, symptoms, pain, notes, and optional health context without being forced to fill out a clinical form.
PRIVATE BY DESIGN
Kept close, not collected.
Your diary is encrypted on your device. There is no Rhyvelle account, cloud sync, advertising, or behavioural analytics.
A SIMPLE PRIVACY PROMISE
Your health story belongs to you.
Rhyvelle is built so we cannot browse, sell, or use your diary for marketing. The things you record stay in the encrypted database on your device.
Read the privacy policy- ✓ No account required
- ✓ App lock with device biometrics
- ✓ Discreet, locally scheduled reminders
- ✓ Delete your data whenever you choose
