No account is required. Reading progress and bookmarks stay on your device; this version does not send your reading activity or health information to a server or AI service. T1 Guide shares education and personal experience. It does not diagnose, monitor glucose, prescribe treatment, or replace your diabetes care team. Work with your care team to choose glucose targets, insulin doses, and a food and activity plan. If you may be having a medical emergency, seek immediate help through your local emergency service.
