A personal note from Mark
Hi, I am glad that you are trying this tool. I have been a Type 1 diabetic for 40 years. I have always struggled with my diabetes management and glucose control. I have tended to have slightly high glucose. I couldn't find a tool to help me that actually would help. So I decided to make my own tool.
I have been using this tool for about 8 months now as I have been developing it. It still isn't a perfect solution but this has been a game-changer for my diabetes management. I want you to experience that practical support and help with your diabetes management too. You are not alone on your journey. I hope this tool can help you!

Your LibreView credentials stay safe
Asking for your LibreView login is a fair thing to be cautious about. Here is exactly what happens to it — and what doesn't.
Used only to sync your data
Your LibreView username and password are used solely to fetch your glucose readings on your behalf — for nothing else, ever.
Encrypted in transit and at rest
Credentials are encrypted the moment they leave your phone and stored encrypted in our secured backend. They are never written to logs in plain text.
Never shared or sold
We do not share, sell, rent, or trade your credentials or glucose data with any third party — no advertisers, no brokers, no exceptions.
Delete it anytime
Disconnect LibreView with one tap and your stored credentials are permanently removed. Export or delete all your data whenever you choose.
