1. Acceptance of Terms

By downloading or using the Tanrr app, these terms will automatically apply to you. Please read them carefully before using the app.

2. Medical Disclaimer & Health Claims

Tanrr is a wellness planning app, not a medical or diagnostic device. It does not diagnose, treat, or prevent disease, and it does not tell users to ignore public health sun protection guidance. The application provides estimates for sun exposure, Vitamin D synthesis, and circadian rhythm support based on algorithms utilizing local UV, weather, skin type, and body-area inputs. Any claims matching "Boost mood" or "Reset your body clock" reflect physiological light response in humans and are intended for wellness support only.

You agree that you remain exclusively responsible for wearing sunscreen, utilizing protective clothing, avoiding sunburn, and consulting with a physician regarding any medical conditions, photosensitive medications, skin cancer risks, pregnancy, or nutrient deficiencies.

3. App Usage

You agree not to use the app in any way that could damage, disable, overburden, or impair the service. You use the estimations and timers provided by the app entirely at your own risk. The developers of Tanrr are not liable for sunburns, skin damage, or any health-related conditions resulting from the use of the app.

4. Intellectual Property

All content, features, and functionalities are owned by Tanrr or its licensors, and are protected by international copyright laws.
