Privacy is a hard rule
Not a marketing line
Your cycle should not become someone else's dataset.
Cycle is designed around local storage. There is no account to create, no analytics or third party software in the app, and no need to send your cycle history to a server. If you choose iCloud sync, that choice is yours. You can also use private app protection features such as Face ID, Touch ID, or a PIN with Premium.
