Thanks for using Guzzle! This page answers the most common questions. If you don't find what you need, email us at and we'll help.

What is Guzzle?

Guzzle is a playful water-tracking app. Set a friendly daily target, log a drink in one tap, and watch your bottle fill while Dewy — your hydration buddy — cheers you on. It keeps streaks, levels, and badges to help the habit stick. Guzzle works entirely on your device with no account and no tracking.

Frequently asked questions

How is my daily target calculated?

Guzzle estimates your daily water target from your age, weight, and climate, using a widely-used rule of thumb: roughly 30–35 ml of fluid per kilogram of body weight per day. We deliberately aim for the middle of that range — enough to keep you well hydrated, but not so high that it's unrealistic or nudges you to over-drink.

From that baseline, Guzzle makes small adjustments — a little more if you're younger or in a hot climate, a little less if you're older or somewhere cool — and then trims about 20%, because a good portion of your daily fluid comes from the food you eat. The result is rounded to a friendly number and never drops below a sensible minimum.

If you like the details, the exact maths is: weight (kg) × 32, then ±250 ml for age, ±150–500 ml for climate, then × 0.8 for the food you eat, floored at 1200 ml.

How do reminders work?

Reminders are optional. When you turn them on, Guzzle schedules gentle local notifications nudging you to drink. They're pace-aware — they adapt to how your day is going and stay encouraging, never guilt-trippy. You can choose an interval or a smarter adaptive cadence, turn the sound on or off, and set quiet hours so you're never nudged while you sleep. Reminders need notification permission; if it's off, Guzzle will let you know rather than pretending to remind you. You can preview a reminder from Settings.

Which drinks count toward my goal?

Water comes first: water (and sparkling water) drive your goal, streak, and rewards. Other drinks like coffee, tea, and juice are tracked alongside as their own daily numbers, so you can see everything you drink without it changing your water goal.

Where is my data stored?

On your device, and nowhere else. Guzzle has no account and no server. Nothing you log is uploaded or shared. See our Privacy Policy for details.

How do I export my data?

Open Settings and choose an export. Guzzle offers two:

You can save or share either file wherever you like. Your data only leaves the device when you choose to export it.

How do I reset my data or redo setup?

In Settings you can reset your data, and you can replay the setup flow to update your profile and target. Replaying setup keeps your existing drink log intact. (Uninstalling the app deletes all Guzzle data from your device.)

Why am I not getting reminders?

Make sure reminders are turned on in Guzzle's Settings, and that notifications are allowed for Guzzle in your device's Settings. Also check your quiet hours — no reminders are delivered during that window.

Does Guzzle give medical advice?

No. Guzzle's hydration suggestions are a friendly guide to help you build a habit, not medical advice. If you have specific health needs, talk to a qualified professional.
