Contracker Privacy Policy

Effective October 30, 2026

Contracker doesn't collect, sell or share your data.

The short version

Contracker works entirely on your iPhone: no account, no sign-in and no network connections of its own.

  • Data collected: none.
  • No tracking, no analytics and no crash reporting, in the app or on this website.
  • Your contractions stay on your iPhone, and deleting the app deletes them.

What Contracker stores

The times, intensity and notes of the contractions you log, plus the app's settings. They are kept in a database on your iPhone that is shared only with the app's own widgets. Contracker doesn't use HealthKit.

What Contracker sends

Nothing. Contracker makes no network connections of its own. The source links in the Guide open in Safari, which is a separate app with its own privacy policy.

Analytics and tracking

The app has no analytics or tracking tools, and no crash-reporting service.

This website

contracker.niomartinez.com uses no analytics and no crash reporting.

Deleting your data

In History you can delete any contraction. Deleting the app deletes everything it stored on your iPhone.

Children

Contracker isn't directed at children and collects no personal information from anyone.

Changes

If this policy changes, the new version will appear on this page with a new effective date.
