GlynceWhere your glucose and food data live
Updated June 29, 2026
Your glucose and food data are processed on your device, not on our servers. They belong to you, and Glynce is built to keep it that way.
What this means
- Your readings and meals stay on your device.
- Glynce does not keep a copy of your glucose history on a server.
- Missing history is recovered from Apple Health, not from us.
Glynce is operated from the Netherlands and follows the GDPR. The full detail of what we collect and why is in our Privacy Policy.
Because your glucose lives on your device rather than our servers, keeping it in Apple Health as well is the reliable way to carry your history to a new phone.
