About
About Period Tracker
Period Tracker brings free period and fertility calculators together with an optional account-based tracker for people who want to keep an ongoing record.
What Period Tracker offers
The site provides a collection of free period and fertility calculators that anyone can use without registering. The calculator directory brings all of the available tools together in one place.
A free tracker is also available with an optional account. Its account features include cloud sync and email reminders.
How calculations and accounts work
The public calculators process the values you enter locally in your browser and return an estimate without requiring an account.
If you choose to use an account, the tracker syncs data with the server for cloud features and sends configured reminders by email. Details about account, health, and usage data are available in the Privacy Policy.
Who maintains the site
Period Tracker is maintained by Period Tracker Developer. Period Tracker remains the name of the product and service you see throughout the site.
Important limits
Calculator results and tracker predictions are estimates. They are provided for informational purposes, are not medical advice, and cannot replace advice, diagnosis, or care from a qualified healthcare professional.
