❓ FAQs - Hydration

How much water do I really need? -

General baseline is 35ml per kg body weight. Our calculator personalizes it with activity and climate so athletes in hot weather get ~3.2L+ while sedentary in cold gets ~2.1L.

Do other drinks count? +

Water is best, but herbal tea, infused water, and low-sugar drinks count ~90%. Caffeine and alcohol dehydrate slightly - add +150ml water for each.

Why visual bottle? +

Visual feedback increases adherence by 28% (behavioral studies). The wave animation shows fill level, making progress tangible versus just numbers.

Is data private? +

Yes. All logs stay in your browser localStorage under key yn_water_v1. No server, no tracking. Clear via Reset.
