Terms of Use

Agreement

By using Meridian, you agree to these terms. If you do not agree, please discontinue use of the app.

Not medical advice

Meridian is an informational and tracking tool. It does not provide medical advice, diagnosis, or treatment plans. The metabolic phase timings, research summaries, and protocol descriptions are for educational purposes only.

You should consult a qualified healthcare provider before starting any fasting protocol, especially if you have pre-existing health conditions, take medications, or are in a population for whom fasting may not be appropriate.

Your responsibility

You assume full responsibility for your decision to fast and for how you use the information presented in Meridian. The app provides tools to track your fasting schedule and general scientific context — it does not prescribe, recommend, or endorse any specific fasting regimen for your individual circumstances.

Accuracy and limitations

While Meridian strives for accuracy in its research content and metabolic phase calculations, we make no warranty that this information is complete, current, or applicable to your individual physiology. Metabolic responses to fasting vary significantly between individuals.

Your data

All fasting data, journal entries, and settings you create in Meridian belong to you. You may export or delete your data at any time through the Settings screen. See our Privacy Policy for details on data storage and handling.

Changes to these terms

We may update these terms from time to time. Continued use of Meridian after changes are published constitutes acceptance of the updated terms.
