The Vessel

LiquidNagger

A water tracker with one line: drink to it. No streaks, no trophies — when the surface meets the line, the water goes glassy-still.

Privacy Policy

Effective: August 2026

LiquidNagger collects no data. None.

Everything you enter — your pours, goal, age, sex, weight, and settings — is stored only on your device (and mirrored to your paired Apple Watch over Apple's local device-to-device channel). The app has no servers, no accounts, no analytics, no advertising, and no third-party code. It makes no network connections at all.

• We do not collect, transmit, sell, or share any personal data.
• Notifications and alarms are scheduled locally by iOS on your device.
• Deleting the app deletes all of its data.

Because no data ever leaves your device, LiquidNagger has no lawful-basis, consent, retention, or data-subject-request obligations to administer — there is simply nothing held about you to request. If this ever changes in a future version, this policy will be updated first and the App Store privacy label will say so.

Health Disclaimer

LiquidNagger offers general hydration guidance based on standard adult intake references. It is not medical advice and not a medical device. If you have a kidney, heart, or other medical condition — or are advised to restrict fluids — consult your doctor about how much to drink.
