Effective October 28, 2026
Hydrostep is built so that your data stays with you. There is no account, no server and no analytics.
Apple Health. With your permission, Hydrostep reads your steps, walking and running distance, flights climbed, and water. It writes only the water you log in Hydrostep. It never changes your steps or any other Health data.
On your devices. Hydrostep keeps a copy of your daily totals, goals and settings on your iPhone so the app opens quickly. It shares today's totals, goals and streaks with your Apple Watch and with Hydrostep's widgets. These copies are excluded from iCloud backups, and you can delete them any time in Settings → Privacy & data.
Reminders. If you turn reminders on, they're worked out on your iPhone from your Health data and scheduled there as local notifications. Nothing is sent anywhere to make them.
It doesn't collect, upload, sell or share your data with anyone, including us.
It has no ads, tracking, analytics or third-party SDKs.
It doesn't use Health data for advertising or anything other than showing you your own progress.
You can change Health permissions any time in the iOS Settings app (Privacy & Security → Health → Hydrostep), turn reminders off in Hydrostep's settings, or delete the app to remove all of its data from your devices. Your Apple Health data remains in Apple Health.
Hydrostep isn't directed at children under 13 and collects no data from anyone.
If this policy changes, the new version will be posted here with a new effective date.
