GulpGulp is designed to work without an account, analytics, advertising, or personal-data collection.
GulpGulp does not collect personal data.
Your water intake records, daily goal, reminder preferences, and widget unlock state are stored locally on your device. Recording streaks and seven-day history are calculated on the device from those local records.
GulpGulp does not track you across apps or websites and does not include advertising, analytics, or social tracking SDKs.
GulpGulp does not require an account or login.
If you turn on the optional daily reminder, GulpGulp asks iOS for notification permission and schedules the reminder locally on your device. Reminder preferences are not sent to a server.
Core hydration tracking works locally. Apple's StoreKit service is used only for the optional widget purchase and restore flow.
GulpGulp is a habit and lifestyle tool. It does not diagnose, treat, or prevent medical conditions. Follow qualified medical guidance if you have fluid-intake limits.
