Terms of Service

Last updated: 3 October 2026

These Terms of Service apply to the GutDiaries and GutCalm apps (together, the Apps), operated by GutDiaries s.r.o., a company based in Prague and registered in Czechia (IČO: 22456864). By accessing or using either App, you agree to be bound by these Terms. If you do not agree, please stop using the Apps.

1. App Overview

GutDiaries s.r.o. operates two mobile apps:

GutDiaries:: food and symptom tracking for GERD, LPR and IBS.
GutCalm:: CBT-based lessons and exercises, and gut-directed hypnotherapy audio, for IBS self-management.

Medical disclaimer

GutDiaries does not diagnose symptoms or replace medical care. The disclaimer below is written for GutCalm and applies to GutDiaries in the same way.

GutCalm supports IBS self-management. It does not diagnose symptoms or replace medical care.

GutCalm is a wellness app for educational and supportive purposes. It offers content based on cognitive behavioural therapy (CBT) and gut-directed hypnotherapy to help you build skills for managing life with irritable bowel syndrome (IBS). It is not designed to diagnose, treat or cure any medical condition.

The app cannot confirm whether you have IBS or rule out other causes of your symptoms. It does not replace an IBS diagnosis by a qualified healthcare professional. Check-ins, scores and progress summaries are tools for reflection, not medical assessments.

Talk to your healthcare provider about your symptoms and before changing any treatment, including medicines or a prescribed diet. Do not delay seeking medical advice because of something you read or do in GutCalm.

Seek medical advice promptly if you notice blood in your stool, unexplained weight loss, symptoms waking you at night, or new gut symptoms when you are over 50. These symptoms need medical assessment, even if you already have an IBS diagnosis.

GutCalm is not an emergency service. In a medical emergency, call your local emergency services.
