Privacy Policy

Data we collect in the app

Data you create in the app

• Hydration logs, including amount, drink type, and timestamp
• Hydration goal and schedule settings
• Unit preference and app preferences

This data supports core app functionality such as progress tracking, reminders, history, and widget or watch sync.

Health data

If you grant HealthKit permission, SipSync may read activity, workout, heart-rate, sleep, body-mass, wrist-temperature, and water-intake data, including step count, active and basal energy, workouts, heart rate, resting heart rate, HRV, sleep analysis, body mass, Apple Sleeping Wrist Temperature, and dietary water. SipSync may also write water-intake entries to Apple Health when you log drinks. Health data is used to power hydration targets, reminders, history, widgets, watch views, and optional Apple Health sync.

Location and weather data

If you grant location permission, SipSync uses your approximate current location to fetch local temperature and humidity through Apple's WeatherKit service. Weather context is used only to improve hydration guidance and is not sold.

iCloud sync

If iCloud is available, SipSync may sync hydration logs, goals, activity snapshots, and app preferences through Apple's private CloudKit database and iCloud key-value storage so your data can stay consistent across your devices.

Subscriptions

SipSync uses RevenueCat to manage in-app purchases, subscriptions, entitlement status, and restore-purchase flows. RevenueCat may process purchase identifiers, subscription status, product identifiers, app user identifiers, and related transaction metadata needed to operate subscriptions.

Analytics and diagnostics

SipSync uses PostHog for product analytics and Sentry for crash or runtime diagnostics. These tools may process events such as screen views, drink actions, onboarding progress, subscription interactions, coarse feature state, stack traces, app version, operating system version, and limited technical context related to failures. SipSync avoids sending raw HealthKit measurements to analytics; some events may include non-sensitive derived flags such as whether activity context was available.

Data we collect on the website

Product update emails

If you submit the marketing site email form, we collect your email address, the submission source, and the time of submission so we can send release notes, support announcements, or product updates related to SipSync.

Email submissions are stored in Cloudflare D1 and are only used for SipSync communications. We do not sell this information.

Third-party services

SipSync relies on service providers such as PostHog, Sentry, RevenueCat, Cloudflare, and Apple platform services including HealthKit, WidgetKit, and WatchConnectivity. Each provider processes data under its own terms and privacy commitments.

How we use data

• Operate hydration tracking, reminders, and sync
• Provide activity-aware hydration targets for users who enable HealthKit
• Use local weather context for more realistic hydration guidance when location permission is granted
• Sync hydration data and preferences through iCloud when available
• Operate subscriptions and restore purchases
• Improve reliability, performance, and feature quality
• Send requested product update communications

Data sharing

We do not sell personal data. We only share data with service providers needed to run SipSync and the SipSync website, subject to contractual and platform controls.

Retention

We retain data for as long as needed to operate the service, troubleshoot issues, send requested product update communications, and satisfy legal obligations.

Your choices

• You can decline or revoke HealthKit permissions in the Health app at any time.
• You can decline or revoke location permission in iOS Settings.
• You can disable notifications in iOS Settings.
• You can stop using the app and delete app data from your device.
• You can unsubscribe from product update emails at any time.

Children

SipSync is not directed to children under 13.

Changes to this policy

We may update this policy when the product, legal requirements, or data processors change. Material changes will be reflected here with an updated effective date.
