Ta vie n'est pas une jauge d'énergie infinie. HYDRA la transforme en barre de vie, comme dans un jeu — et chaque verre d'eau, chaque café, chaque verre d'alcool la fait monter ou descendre en direct. Abonnement requis (7 jours d'essai gratuit, puis 3,99 €/mois). COMMENT ÇA MARCHE • Une barre de vie sur ton écran d'accueil et ton écran verrouillé (widget natif iOS), qui se vide toute seule selon ta physiologie réelle. • Bois de l'eau ou un café : la barre remonte instantanément. • L'alcool — le "poison" — la fait chuter plus vite qu'elle ne remonte. • Le calcul prend en compte ton poids, ton sommeil et ton environnement (température, humidité, altitude) pour un besoin d'hydratation qui te correspond vraiment, pas une règle générique "2 litres par jour". POURQUOI C'EST DIFFÉRENT La plupart des apps d'hydratation te demandent de cocher des cases. HYDRA transforme l'hydratation en un jeu simple à lire d'un coup d'œil : ta barre de vie. Pas de graphiques à interpréter, pas de calculs à faire — juste une couleur (vert, ambre, rouge) qui te dit où tu en es, là, maintenant. RAPPELS INTELLIGENTS Reçois une alerte avant que ta barre passe en zone ambre ou rouge, et des rappels étalés dans la journée pour le nombre de verres qu'il te reste à boire avant ton coucher — jamais après, jamais du bruit inutile. CONFIDENTIALITÉ Tes données (poids, journal de boissons) ne servent qu'à faire fonctionner l'app. Aucune publicité, aucune revente de données, aucun tracker tiers. Suppression de compte en un geste, directement dans l'app. HYDRA fait référence à la consommation d'alcool à des fins de suivi personnel et n'encourage pas sa consommation. ABONNEMENT REQUIS HYDRA est une application par abonnement. L'accès aux fonctionnalités (barre d'hydratation en temps réel, widgets écran verrouillé et écran d'accueil, historique et statistiques) nécessite l'abonnement HYDRA Pro. • HYDRA Pro — abonnement mensuel à 3,99 €, après 7 jours d'essai gratuit • L'abonnement se renouvelle automatiquement sauf annulation au moins 24 h avant la fin de la période en cours • Gestion et annulation à tout moment dans les réglages de ton compte Apple • Conditions d'utilisation (EULA) : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ • Politique de confidentialité : https://hydra-landing-sooty.vercel.app/privacy.html HYDRA n'est pas un dispositif médical et ne fournit aucun diagnostic. Les calculs reposent sur des coefficients physiologiques publiés, dont les sources sont citées dans l'app (WIDGETS → SCIENCE → SOURCES SCIENTIFIQUES). Consulte un professionnel de santé pour tout besoin d'hydratation spécifique.
