Privacy Policy

1. Information we collect

We only collect what Sippy needs to work.

Sippy does not include Firebase Analytics or Crashlytics, and does not read your contacts, photos (other than one you pick as a profile photo), or precise GPS location.

2. How we use it

• Calculating your daily water goal from your profile and, if allowed, the local temperature.
• Scheduling water and meal reminders between your wake-up time and bedtime.
• Showing your progress in an optional Android status bar notification.
• Running Circle: friend requests, groups, cheers, nudges and shared daily progress.
• Restoring your profile and Premium purchases on a new phone.
• Showing ads to free users, and turning on app settings and design tests through Firebase Remote Config.

We don't sell your personal information, and we don't share it with data brokers.

3. Where it's stored

On your phone

Individual drink entries, cup sizes, reminder plans, streak calculations and goal history are saved in Sippy's private storage on your device. They are removed if you clear the app's data or uninstall it.

In the cloud (only with an account)

When you're signed in, we use Google Firebase to store your profile (display name, username, avatar, gender, daily goal, today's total, current streak), your public profile used to find friends, your daily totals, Circle friendships, friend requests, groups and their activity, and your push notification token. A profile photo you upload is stored in Firebase Storage.

4. Location & weather

If you allow it, Sippy asks for approximate location only (ACCESS_COARSE_LOCATION on Android, "While Using" on iOS). Coordinates are rounded to about 1 km and sent to Open-Meteo to get today's temperature. No name, email or account ID is sent with them.

If you say no, or switch it off later in your phone's settings, Sippy simply uses your regular goal.

5. Circle (friends & family)

• Circle is opt-in. You connect with people by username, friend request, invite code or invite link. Invite codes expire after 24 hours.
• People in your Circle can see your display name, username, avatar or photo, today's total, today's goal and your streak.
• They can't see your weight, sleep times, individual drinks or location.
• You can remove a friend or leave a group at any time, and sharing with them stops.

6. Advertising

The free version shows banner, native, interstitial and optional rewarded ads from Google AdMob. AdMob may collect your device's advertising ID, approximate region from your IP address and how you interact with ads. See how Google uses data from apps.

On iOS, Sippy asks permission through Apple's App Tracking Transparency prompt before ads can be personalized. On Android you can reset or delete your advertising ID in your phone's Google settings. Premium removes all ads.

7. Purchases

Premium is sold through Google Play and the Apple App Store. They handle payment. Sippy never sees your card number, bank details or billing address; we only receive confirmation of what you bought so we can unlock it.

8. Service providers

These companies process data on our behalf, under their own privacy terms:

• Google Firebase (Authentication, Firestore, Storage, Cloud Messaging, Remote Config, Cloud Functions) — privacy
• Google Sign-In — privacy
• Google AdMob — privacy
• Open-Meteo (weather) — terms
• Google Play Billing and Apple App Store — Apple privacy

We may also share information if the law requires it, or to protect the safety of our users.

9. Keeping & deleting data

We keep cloud data while your account exists. Data on your phone stays until you clear it or uninstall Sippy.

• Delete your account in the app: open Settings, scroll to the bottom and tap Delete account. Your sign-in, profile, username, friendships, friend requests and group memberships are deleted right away.
• Can't get into the app? Follow the steps on our account deletion page.

Any remaining copies, including backups, are removed within 30 days. Purchase records kept by Google or Apple are governed by their policies.

10. Your choices & rights

You can view and change your profile in the app, turn off location, notifications or the status bar notification, and delete your account. Depending on where you live (for example under the GDPR in the EU/UK or the CCPA in California), you may also have the right to access, correct, export or delete your data, or object to how it's used. Email us to make a request, and we'll reply within 30 days.

11. Security

• All network traffic uses HTTPS/TLS.
• Database rules only let you read and write your own data and the Circle data you've been given access to.
• Passwords are handled by Firebase Authentication. We never see or store them in plain text.

No system is perfectly secure, but we work to protect your information and will tell you if a breach affects you, as the law requires.

12. Children

Sippy is for a general audience and isn't directed at children under 13 (or under 16 in the EEA/UK). We don't knowingly collect personal information from them. If you think a child has given us their information, contact us and we'll delete it.

13. Changes to this policy

If we change this policy we'll update the date at the top of this page, and tell you in the app if the change is significant.
