Privacy Policy

Last updated: August 31, 2026

Who we are

Murmur is an iOS app published by BUNKER GAMES. You can contact us at freesailinc@gmail.com.

Data we collect

Murmur does not collect app usage data on our servers. The current app version does not include third-party analytics, advertising networks, tracking SDKs, or an account system.

If you contact us by email for support, bug reports, or feature suggestions, we receive the email address, message content, and any device or app details you choose to include in that email. We use this only to respond, investigate bugs, and improve the app.

Data stored on your device

Murmur stores the following information locally in the app's private storage on your iPhone or iPad:

• Drink entries, including amount, drink type, drink volume, time, and optional cocktail details.
• Daily goal history and hydration statistics derived from your entries.
• Optional profile settings used for goal estimates, such as age or birth date, weight, sex, pregnancy or breastfeeding status, medical fluid-limit setting, activity preference, and weather-style preference.
• Custom drink definitions, custom colors, and drink preferences.
• App preferences such as units, language, week start day, notification settings, quiet hours, and motion settings.

This local data is not sent to BUNKER GAMES or to third parties by Murmur.

Health, wellness, and sensitive information

Murmur may ask you to enter health-related or wellness-related information so the app can estimate a hydration goal. This information stays on your device and is used only for app features you use locally.

Murmur does not use health, fitness, or medical information for advertising, marketing, tracking, or data mining.

Apple Health and location

The current app version does not request Apple Health access and does not collect precise location data. Some settings may let you describe activity or weather conditions manually so the app can estimate your hydration goal on-device.

Notifications

If you enable notifications, Murmur asks iOS for notification permission. Reminder settings are stored locally. Notifications are generated by the app and do not require a Murmur server.

You can turn notifications off in the app or in iOS Settings at any time.

Purchases and subscriptions

Murmur may offer optional paid features through auto-renewable subscriptions and one-time in-app purchases. Purchases are processed by Apple through the App Store using StoreKit. We do not collect, receive, or store your payment card number, bank account details, Apple Account password, or other payment credentials.

The app may receive limited purchase-related information from Apple, such as product identifiers, transaction identifiers, purchase status, subscription status, expiration or revocation status, and entitlement information. Murmur uses this information only to display available products, verify purchases, restore purchases, provide access to paid features, prevent misuse, and handle support requests if you contact us about a purchase.

Murmur does not use RevenueCat or another third-party subscription management provider in the current app version.

Third-party services

Murmur does not integrate third-party analytics, advertising, crash reporting, subscription management, or tracking services in the current app version. App Store purchases are processed by Apple. Email support may be handled by the email services used by you and by us.

Data retention and deletion

Local app data remains on your device until you delete it in the app, reset relevant settings, or delete the app from your device. Deleting the app removes the local app data stored by Murmur.

Support emails are retained only as long as reasonably necessary to respond to your request, maintain support records, and protect our legal interests. You can request deletion of support emails by contacting freesailinc@gmail.com.

Your choices

• You can use Murmur without an account.
• You can choose not to enter optional profile information and use a manual goal instead.
• You can disable notifications in the app or in iOS Settings.
• You can manage subscriptions, cancel renewals, request refunds, and view purchase history through your Apple Account and App Store settings.
• You can delete local app data by deleting the app from your device.

Children's privacy

Murmur does not knowingly collect personal information from children. Since the app does not use accounts, analytics, advertising, or server-side collection, hydration data entered in the app remains local to the device.

Changes to this policy

We may update this Privacy Policy if Murmur's features or data practices change. If a future version introduces materially different data collection, we will update this page and, where appropriate, notify users in the app or through App Store metadata.
