How to Sync Your Medtronic Pump with SweetLife via CareLink
If you use a Medtronic insulin pump with a Guardian CGM sensor, you probably already upload your data to CareLink -- Medtronic's cloud platform for viewing pump and sensor readings. But what if you could see that data alongside your meal logs, insulin doses, and AI-powered insights all in one place? That is exactly what SweetLife's CareLink integration does.
What Is CareLink?
Medtronic CareLink is the official cloud platform where your Medtronic pump and Guardian CGM sensor upload data. Clinicians use it to review your glucose trends, and you can access it through the CareLink Connect app or web portal. It stores your CGM readings, insulin delivery history, active insulin levels, and more.
The problem? CareLink shows you the raw data, but it does not connect it to the rest of your diabetes life -- what you ate, how much insulin you took manually, or patterns your doctor should know about. That is where SweetLife comes in.
Why Sync CareLink to SweetLife?
When you connect CareLink to SweetLife, your pump and sensor data flows directly into the app. This means you can:
- See CGM readings alongside your meal and insulin logs in one unified timeline
- Get smarter insights from Chug, your AI buddy, who can factor in your pump data when analyzing trends
- Generate doctor-ready PDF reports that combine all your data -- not just what the pump recorded
- View better charts with time-in-range breakdowns that account for everything
What You Will Need
Before you start, make sure you have:
- An active Medtronic CareLink account (the same one you use on carelink.minimed.com or the CareLink Connect app)
- A Medtronic pump paired with a Guardian sensor that uploads to CareLink
- SweetLife installed on your iPhone (free on the App Store)
Step-by-Step: Connect CareLink to SweetLife
The whole process takes about two minutes. Here is how to do it:
-
Open SweetLife and go to CareLink settings.
Launch SweetLife on your iPhone. Tap your profile icon in the top corner, then tap CareLink. This opens the CareLink connection screen. -
Select your region.
You will see two options: US or EU. Pick the one that matches where your CareLink account was created. This makes sure SweetLife connects to the correct Medtronic server. If you are unsure, go with the region where you signed up for CareLink. -
Log in with your CareLink credentials.
A secure WebView will appear showing the official Medtronic CareLink login page. Enter your CareLink username and password just like you normally would. SweetLife never stores your password -- it only captures a secure session token to fetch your data. -
SweetLife captures your session and starts importing.
Once you log in successfully, SweetLife securely saves your session and immediately begins pulling in your latest pump and CGM data. You will see your readings appear in the app within seconds. -
Data syncs automatically from now on.
Every time you open SweetLife, it checks for new data from CareLink and imports it in the background. There is nothing else you need to do -- no repeated logins, no manual refreshes. It just works.
What Data Gets Imported?
SweetLife pulls in the most important readings from your Medtronic system:
These readings get woven into your SweetLife timeline and charts, right alongside your manually logged meals, finger-stick checks, and notes. Chug, your AI companion, uses all of this combined data to give you more accurate and personalized insights.
Troubleshooting
CareLink sessions expire from time to time -- that is normal and happens on Medtronic's end. If you notice your data has stopped updating, here is what to do:
If you are still having trouble, make sure your CareLink account is active by logging in directly at carelink.minimed.com. If that works, reconnecting through SweetLife should too. You can also reach us at support@sweetlifeapp.com and we will help you sort it out.
Your Data Stays on Your Device
SweetLife is built with a privacy-first approach. Your CareLink data is stored locally on your iPhone -- we do not upload it to our servers. Your session token is saved securely in the device keychain, and all communication with Medtronic's servers happens directly from your phone. You stay in control of your health data at all times.
