How can we help?

DrinkAI uses Sign in with Apple or Google for authentication. Simply tap your preferred option on the welcome screen. No passwords to remember, and you can use Apple's Hide My Email feature for extra privacy.

Your goal is calculated using your weight (33 ml per kg per day as a baseline, per IOM/EFSA standards), adjusted for your age, gender, and activity level. We also account for the roughly 20% of water intake that comes from food. This gives you a personalized, science-backed target rather than a generic number.

DrinkAI requires iOS 18 or later. We use the latest SwiftUI features to deliver the best possible experience.

Point your camera at any beverage and tap scan. Our AI identifies the drink type, estimates its volume, and calculates nutritional content including caffeine, sugar, calories, and hydration efficiency. You can review and adjust the results before logging.

Photos sent for AI scanning are processed in real time and not retained by the AI provider. Additionally, all AI requests are routed through a proxy, so your IP address is never shared with the AI service. We do not store drink photos.

After scanning, you can edit all fields before logging - drink type, name, volume, and nutritional values. You can also edit any logged drink from the Journal tab at any time. Tips for better scans: ensure good lighting, capture the full drink, and avoid obstructions.

Pro unlocks AI-powered drink scanning, detailed weekly insights with charts and trends, achievements and streak tracking, personalized AI recommendations, and full data sync across devices.

Subscriptions are managed through the Apple App Store. Go to Settings > Apple ID > Subscriptions on your iPhone to manage or cancel. You'll retain Pro access until the end of your billing period.

Refunds are handled by Apple. You can request a refund at reportaproblem.apple.com. If you're having issues with the app that led to your request, please contact us first - we'd love to help resolve it.

Go to Profile > Delete Account in the app. This permanently removes all your data including profile, drink logs, achievements, and photos. You can also email drinkai@teyrex.com to request deletion.

Yes, partially. Your drink history and profile are cached locally (up to 100 MB), so you can view your data and log drinks manually without an internet connection. AI scanning and weekly insights require connectivity. Data syncs automatically when you're back online.

Check that notifications are enabled in both the app (Profile > Notifications) and your device settings (Settings > DrinkAI > Notifications). DrinkAI uses local notifications, which don't require an internet connection but do need system permission.

Streaks require meeting your daily hydration goal each day. If you missed a day, the streak resets. Make sure to enable hydration reminders to get nudges before your streak is at risk. We send a special "streak risk" notification at 8 PM if you haven't met your goal.

Make sure camera permission is granted in Settings > DrinkAI > Camera. If you previously denied access, you'll need to enable it from iOS Settings as the app can't re-prompt. Restart the app after changing permissions.
