Effective: April 23, 2026 · Last updated: April 23, 2026

These Terms govern your access to and use of Culprit, operated by an individual developer based in the Republic of Korea. By using the app, you agree to these Terms. If you do not agree, do not use the app.

1. Eligibility

You must be at least 16 years old to use the app.

2. Description of Service

Culprit helps users run a structured food-elimination and reintroduction program and track the patterns between meals and symptoms. Features include a 14-day elimination phase with allowed/avoiding food reference, meal and symptom logging, a reintroduction scheduler with washout enforcement, and AI-generated pattern summaries that describe how often particular foods were logged before symptoms rose. Certain features ("Culprit Pro") require a paid subscription.

3. Medical Disclaimer

Culprit is not a medical device and does not provide medical advice, diagnosis, or treatment. The pattern analysis summarizes your own logs in qualitative language only and is not a clinical assessment. Information in the app is for informational purposes only and is not a substitute for professional medical advice. Always consult a qualified healthcare provider before making dietary, medical, or lifestyle decisions, and especially before starting an elimination diet if you are pregnant, breastfeeding, have a diagnosed eating disorder, or have any chronic medical condition.
