Optionally sync your water intake with Apple Health on iOS — Water Reminder can both write your entries to Health and read your existing dietary water samples. You stay in full control of what is shared.

• Write water intake to HealthKit with your permission only
• Optionally read existing dietary water samples from Apple Health
• Water logged elsewhere and read from Apple Health is shown separately from entries you created in Water Reminder
• Deleting a Water Reminder entry can delete the corresponding HealthKit sample it created
• No Health data used for advertising, marketing, or data mining
• Manage permissions in the Health app or iOS Settings at any time
• Water Reminder is not a medical app and does not provide medical advice

Go beyond water — log any beverage using your own custom drinks and containers, each with the sizes you actually use.

• Create custom drinks and recipes beyond the built-in presets
• Define custom containers with your own volumes for one-tap logging
• Custom drinks, recipes, and containers are all included in your JSON data export
• Custom drink recipes and containers sync via optional iCloud sync; quick custom drinks without a saved amount stay local to each device

Water Reminder can adjust your daily hydration goal using the current weather near you, using location only to fetch a temperature — never stored as coordinates.

• Optional: uses Apple WeatherKit with approximate, When-In-Use location only
• Looks up the current weather to suggest a weather-aware hydration goal
• Your precise location is never stored — only the resulting temperature and a timestamp are cached locally
• Works fully without location access; you can always set your goal manually

Turn on iCloud sync to keep your hydration data up to date across your own devices — stored only in your private iCloud account, never accessible to the developer.

• Syncs hydration entries, containers, custom drink recipes, and output/bathroom events
• Your daily goal, reminders, achievements, and weather settings always stay local to each device — even with sync on
• Uses your own private CloudKit database — Apple infrastructure the developer cannot access
• Off by default; nothing syncs to iCloud unless you turn it on
• Turning sync off stops future syncing; use "Delete iCloud Data" in the app, or Settings → iCloud on your device, to remove already-synced records
• The app works fully with sync disabled — everything is local-only by default

Optionally log bathroom events alongside your hydration intake, with room for your own notes and estimated amounts.

• Log output/bathroom events separately from drink entries
• Add an optional note and an estimated amount to each event
• Included in your local data and in your CSV/JSON export
• Entirely optional — nothing is logged unless you add it

Take your data with you at any time in CSV or JSON format — including data most hydration apps leave out.

• Export to CSV or JSON directly from the app
• JSON export includes hydration entries, containers, custom drinks and recipes, your daily goal and settings, and output/bathroom events
• CSV export is a single table of your hydration entries — use JSON for full data including containers, custom drinks, and output events
• No account or cloud step required — export happens on-device

Water Reminder is built with privacy as a core principle — not an afterthought. Your hydration data is yours alone.

• No account required — start tracking immediately
• No developer-controlled hydration-data backend, API, or database
• All hydration data stored locally on your device by default
• Optional private iCloud sync keeps your data within your own iCloud account — never visible to the developer
• No advertising, no third-party tracking, no analytics
• Widget data shared locally through App Group storage
• Apple Watch sync keeps only your own devices in sync
