← HomeCycle Tracker
Your cycle, understood.
Log your period day by day and this fills in the picture over time — your average cycle, your fertile window, and whether your pattern is worth a closer look. Common doesn't mean normal, and the same goes for your cycle.
How this data is handled
Cycle data is sensitive, so we treat it that way: no ad trackers, nothing sold or shared with anyone, and until you choose to sign in, nothing here ever leaves this device. You decide if and when it's saved to an account.
