Your privacy is our priority! With PKE (Public Key Encryption) and Anonymous Mode, you can track your cycle worry-free. PKE means only *you* can access your data. Your private key stays on your device, so even we can’t see it—it’s like a private room just for you. Anonymous Mode goes even further: no email, no identifiers. If you delete the app, there’s no way to trace your data back to you. Total privacy, guaranteed. With Period Diary, you’re in control of your health and your privacy. #PeriodD
