Water Buddy — Privacy Policy

Last updated: October 28, 2026

Water Buddy ("the app", "we") is a water tracker. This policy explains what data the app handles and why. In short: your water log stays on your device, and we do not run any servers that receive it.

Data stored only on your device

The following never leaves your phone unless you back up your device with Apple or Google:

• Water and other drinks you log (amounts, times and the type of drink), daily totals and streaks
• Your daily goal, and the weight and activity level you enter to calculate it (only the resulting goal is stored)
• Reminder schedule, cup sizes and Buddy's outfit
• Whether you finished onboarding, and whether the app has already asked you for a rating

We cannot see, access or recover this data. Deleting the app deletes it.

Purchases and subscriptions

Subscriptions are processed by Apple (App Store) or Google (Google Play). We never receive your payment details.

To check whether you have an active subscription, the app uses RevenueCat (RevenueCat, Inc.), a subscription service provider. RevenueCat receives:

• an anonymous, randomly generated app user ID (not linked to your name, email or phone number);
• your purchase and subscription history from the App Store or Google Play;
• basic device and app information needed to validate purchases (for example, app version, platform, country/store).

This data is used only to provide and restore your subscription. See RevenueCat's privacy policy: https://www.revenuecat.com/privacy

Exporting your history

With Pro, you can export your daily totals as a CSV file. The app creates the file on your device and opens your phone's share sheet; the file goes only where you choose to send it (for example email, Files or a cloud drive). We never receive it. Whoever you share it with handles it under their own terms.

Rating the app

Once, after you have met your goal on three days, the app may show the App Store or Google Play rating window. That window is run by Apple or Google: a rating or review you leave there is handled by them under their policies, and we see it only as a public review on the store. "Rate Water Buddy" in Settings opens the same window or the store page.

Notifications

If you allow notifications, reminders are scheduled locally on your device. No notification data is sent to us.

What we do not do

• No account or sign-in
• No ads and no advertising identifiers
• No selling or sharing of personal data
• No tracking across other apps or websites

Children

Water Buddy is not directed at children under 13 and we do not knowingly collect personal information from them.

Your choices

• You can turn reminders off in Settings at any time.
• You can manage or cancel your subscription in your App Store or Google Play account settings.
• To ask about the purchase data held by RevenueCat, or to request its deletion, contact us at the address below.

Health information

Water Buddy offers general hydration guidance. It is not a medical device and does not provide medical advice.
