Partus collects no data. The app has no account, no sign-in, no analytics, no advertising and no third-party code. It never connects to the internet: every calculation happens on your device, and the only stored value (the last entered date) stays in your device's local storage. Nothing is ever transmitted to us or to anyone else.
Because no data is collected, there is nothing for us to share, sell, or delete. If you have any questions about this policy, contact ep@tommano.com.
Effective date: July 29, 2026.
Partus is a reference calculator for healthcare professionals. It does not provide medical advice or diagnosis.
