About Private Period Tracker
A Note from the Developer "When I looked for a way to track my cycle, I was shocked. Most apps required an account and 'anonymized' data sharing. As an engineer and a mom of two, I know that once your data is on someone else's server, you lose control. I didn't want my health history to be a product for sale. I wanted a digital version of a paper notebook—something only I could see. That’s why I built this tracker to be 'Local-Only.' Your phone is the vault, and your data lives and dies on your device."
