Polar's steps#
Polar's support article "How to download all your data from the Polar ecosystem" covers users of the Polar Flow and Polar Beat apps:
- Go to account.polar.com and sign in using your Polar account email address and password.
- In the left-hand menu, click Download your data, or scroll down to find the section.
- Click the Download button to initiate the request and begin the data collection process.
"You will get an email when your data is ready to be downloaded." Polar says collection takes some time, depending on the amount of data and other data collection traffic, and "You will have two weeks to download the data, once you get the email."
What is in it, and what is not#
In Polar's words, the export "contains all of the Polar Flow data that was originally provided by you (for example, data given by you during the account registration process), and most of the data coming from the Polar devices or Polar apps you use." It "does not include any data that is derived from the data provided by you using Polar algorithms so, for instance, activity and sleep information are not included in the exported file."
So a Polar export is raw recordings and your own inputs, not the daily activity and sleep summaries you see in the app. If those summaries are what you want, the API is the route.
Team products differ: for Polar Team Pro, Polar says your team is responsible for the data and that it can be downloaded or transferred to a third party via the Team Pro API; the Polar Team app has a download under Settings.
AccessLink for your own account#
Polar's AccessLink API v3 documentation calls AccessLink "the access channel to the training and daily activity data recorded by Polar devices", and says "Any registered Polar Flow user can create API client to AccessLink" at admin.polaraccesslink.com, authenticating with OAuth2. You then register your own user through the API before reading data. The Polar API integration guide covers the flow and its limits.
Analyze what you get#
The activity-list notebook shows weekly training volume by sport in pandas on a synthetic per-workout CSV; this site has not verified the layout of Polar's export files, so the notebook uses its own columns.
Frequently asked questions
How long do I have to download my Polar data export?
Two weeks from the email. Polar's support article says you will get an email when your data is ready to be downloaded, and that you will have two weeks to download the data once you get it. Collection itself takes a variable time, depending on the amount of data and other collection traffic.
Why are activity and sleep missing from my Polar export?
Because Polar leaves out anything its algorithms derive. Polar says the export does not include any data derived from the data you provided using Polar algorithms, so activity and sleep information are not included in the exported file. It does contain the data you provided and most of the data from your Polar devices and apps.
Can any Polar Flow user create an AccessLink API client?
Yes, by Polar's own documentation: any registered Polar Flow user can create an API client to AccessLink by filling in application details at admin.polaraccesslink.com. AccessLink uses OAuth2, and a user must be registered through the API before their data can be read.
