How do I log a movement? On the Today tab, tap any Bristol type tile to log it now, or long-press a tile to add details (size, urgency, blood/mucus, notes, time).
Do I need an account? No. There is no account or login. Your data is stored only on your device.
How do I export or delete my data? In Settings, use "Export CSV" to save your data, or "Delete all data" to remove everything permanently.
What is GutLog Plus? An optional subscription that unlocks 90-day trends, unlimited PDF reports, trigger correlation, and custom tags. Manage or cancel anytime in your iPhone's Settings → Apple ID → Subscriptions.
See our Privacy Policy. Short version: no data collection, no tracking, no accounts — everything stays on your device.
