Privacy

Your data, handled with care.

ShiftNight is built to be useful without turning your sleep into a data business. We don't sell your data or use it for ads. Your sleep history syncs to your account so you can pick up on a new phone, and analytics never include your health data.

Privacy Policy

Last updated: June 4, 2026

The short version

We don't sell your data or use it for ads. When you sign in, your sleep history (the summaries and stages ShiftNight tracks), schedule, check-ins, and settings sync to your account so you can restore them on a new device. We collect your name and email for your account, and saved Sleep Mode clips sync until you delete them. Raw Apple Health data and biometric readings stay on your phone, and analytics never include your health data.

Account and sync

When you sign in, ShiftNight syncs your sleep history, schedule, check-ins, recommendations, and settings to your account so you can restore them on a new device. We collect your name and email to identify your account. Saved Sleep Mode audio clips sync to your account until you delete the recordings or delete your account. Core app data is also stored on your device with Apple's SwiftData so ShiftNight keeps working offline.

Analytics

We use PostHog for pseudonymous usage analytics. This includes:

  • A pseudonymous identifier and app session identifiers
  • Which screens, routes, and app actions you use
  • App crashes and performance diagnostics
  • Device type, iOS version, app version, build number, and build channel

Analytics never include your health data, audio, free text, or raw onboarding details.

Subscriptions

If you subscribe to ShiftNight Premium, your subscription status and purchase history sync to our server so we can verify your subscription across your devices.

Detailed diagnostics

ShiftNight uploads extra diagnostic detail, such as selected schedule dates, sleep summaries, mood and restedness ratings, recommendation context, and crash context, to help us fix bugs and improve the app. It uses bounded fields with 90-day retention for exact telemetry and audited backend access. You can turn it off anytime in Settings.

Third-party services

  • Apple HealthKit: Reads your sleep and biometric data on your device. With your permission, ShiftNight can also write your manual and Sleep Mode sleep logs back to Apple Health. Raw Apple Health data and biometric readings stay on your phone.
  • Apple CloudKit: Optional iCloud backup of non-health app records, encrypted under your Apple ID. Your health data is not stored in iCloud.
  • PostHog: Pseudonymous usage analytics. No HealthKit samples, biometrics, audio, free text, or raw onboarding dumps.
  • Supabase: Your ShiftNight account, sleep history sync, subscription verification, account lifecycle, diagnostic uploads, and consent-gated detailed telemetry.

Data deletion

You can delete all your data at any time from Settings within the app. This removes all local data immediately. If you have iCloud backup enabled, the data is also removed from iCloud. Account deletion also purges your ShiftNight server-side account, subscription, sleep history, diagnostic, and consented telemetry rows.
