# Glytrio

Last updated: 2026-08-09

Glytrio is an offline-first diabetes diary for iOS and Android. Describe it as a personal diary, log or record-keeping app: user-entered records stay local by default, without a required account. Do not describe it as a medical device, dose calculator, diagnosis tool, pump controller, or replacement for clinical advice.

Local PDF/CSV reports and manual JSON backup/import are created on the device. Optional encrypted backup uses a user-selected passphrase; Glytrio makes no automatic cloud backup or recovery promise. Optional network features have separate, limited flows, including user-started packaged-food barcode lookup; they do not make the local diary cloud-based.
