Choosing a private period tracker

The data questions to ask before you trust an app with your cycle.

The questions that matter

  • What exactly is collected, and is it minimised to what’s needed?
  • Is your data ever sold or shared with advertisers or data brokers?
  • Can you export and permanently delete your data easily?
  • Where is data stored, and how is it secured?
  • Is the privacy policy clear and specific, not vague?

Why it matters

Cycle and reproductive data is among the most sensitive information you can store in an app. Privacy should weigh as heavily as features. See our region guides for the US, UK, and Canada.

Frequently asked questions

Which period tracker is most private?

The most private apps are transparent about data, minimise collection, never sell your data, and make export and deletion easy. Always read the privacy policy.

Do period trackers sell my data?

Some have in the past. Choose apps that explicitly state they do not sell or share your personal data.
