Where Does Dexcom Store Glucose Readings?
Dexcom CGM readings on the account with Clarity reports and app cache.
Last updated
Dexcom keeps continuous glucose readings on the account (G6/G7 apps plus Clarity web reports) with the phone app caching recent traces for offline graphs. Sensors pair per phone; transmitters bridge the gap.
Clarity is the archive: AGP reports, patterns and data sharing with clinics live there independent of any phone. Follow invitations let caregivers watch live. Reinstalls restore history on login while the active sensor session usually needs restarting on the new phone.
Where Dexcom stores this, by platform
Account cloud with Clarity (readings) plus app cache per phone
Pair the transmitter per device; one sensor session feeds one phone officially. Clearing app data drops local traces; Clarity keeps the history. Export AGP reports for the clinic.
Account cloud with Clarity (same synced readings on iPhone)
HealthKit sharing optional per category. Deleting the app clears cache only. Start a fresh sensor session on the new phone after moving; old sessions do not transfer.
Frequently asked questions
how do I share Dexcom data with my clinic
Invite the clinic in Clarity for ongoing sharing, or generate AGP PDFs per period. The account holds the full trace; the phone app shows the recent window.
does switching phones lose Dexcom history
No for history: Clarity restores it on login. The live sensor session restarts on the new phone, with a warmup gap. Pair fresh and keep the old phone until overlap ends.
