How to use your Polar product securely
Polar offers a minimum of five years of product support service to its customers from the sales start of the product.
Product support service includes necessary firmware updates to Polar devices and fixes for critical vulnerability as
required. Polar constantly monitors the releases of known vulnerabilities. Please update your Polar product regularly, and
as soon as the Polar Flow mobile application or Polar FlowSync computer software informs you about the availability of a
new firmware version.
Training session data and other data saved on your Polar device include sensitive information about you such as your
name, physical information, overall health and location. Location data can be used to track you when you are out training
and to find out what your usual routes are. For these reasons use extra caution when storing your device when not using it.
If you use phone notifications on your wrist device, be aware that messages from certain applications will be projected on
the wrist device display. Your latest messages can also be viewed from the device menu. To ensure the confidentiality of
your private messages, refrain from using the phone notifications feature.
Protect your data by setting a six-digit PIN on your watch. When a PIN is enabled, your watch automatically locks when
removed from your wrist and requires the PIN to unlock. This helps ensure that even if your watch is lost or stolen,
unauthorized users cannot access your personal information. Additionally, the PIN protects the USB connection to a
computer, allowing you to safely charge your watch on any computer while controlling data transfer between devices. You
can set a PIN during setup or later by going to Settings > Data & security > Set PIN. For more information, see Setting up
and using a PIN on your watch.
Before handing the device over to a third party for testing or before selling it, it is necessary to perform a factory reset on
the device, and to remove the device from your Polar Flow account. For instructions on performing factory reset, see
Restarting and resetting. A factory reset will clear the device memory, and the device cannot be linked to your data
anymore. To remove the device from your Polar Flow account, sign into the Polar Flow web service, choose products and
click the “Remove” button next to the product you wish to remove.
The same training sessions are also stored on your mobile device with the Polar Flow application. For extra security,
various security enhancing options can be enabled on your mobile device such as strong authentication and device
encryption. Consult the user manual of your mobile device for instructions on enabling these options.
When using the Polar Flow web service, we recommend using a password that is no less than 12 characters in length. If
using the Polar Flow web service on a public computer, please remember to clear the cache and browsing history in order
to prevent others from accessing your account. In addition, do not allow a computer’s browser to store or remember your
password for the Polar Flow web service if it is not your private computer.
