Frequently Asked Questions

Does this mean I can use Tidepool if I don't live in the United States?

Our Privacy Policy and Terms of Use are currently intended for folks registering in the United States. That said, we know that people travel outside the U.S., and we know that there are people in the U.S. using mmol/L. We will never block access to our service or your data, but we can’t yet guarantee that we comply with data privacy laws in other countries.

From our Terms of Use, “You understand that to register as a User of Tidepool Apps you must be in the United States. We make no claims that Tidepool Apps are accessible or appropriate outside of the United States. Access to Tidepool Apps may not be legal by certain persons or in certain countries. If you access Tidepool Apps from outside the United States, you do so on your own initiative and are responsible for compliance with local laws.”

Can I use my meter that only displays in mmol/L?

That’s tricky. Devices upload either in mg/dL or in mmol/L. Very few let you set the units yourself, and this is typically hardcoded by the device manufacturer. We’re working to add support for all mmol/L devices, but unless we actually have a mmol/L version of a particular device in our hands, we can’t test it to make sure our software will behave properly.

If you have a mmol/L device and it's not displaying data correctly in Tidepool or you’re using a device that uploads in mmol/L that we don’t yet support, please send an email to

What about some other device that I use for my diabetes management that you don't yet support?

If you are using a device that is not yet supported by Tidepool, please send an email to so we can prioritize our engineering efforts.
