A period tracker that keeps your data where it belongs: with you.
Private. Local. Secure. Period tracking without the extraction.
Why CycleVault?
Because most period apps know too much.
Data Over-Collection
Most apps track interactions, location, and identifiable data far beyond what's needed for a calendar.
You Are The Product
Many "free" apps monetize by building a profile of you to sell to advertisers and data brokers.
