Tracking & Data

What does Burrow track?

Burrow uses your phone's microphone and motion sensors to monitor sound events and movement throughout the night. Sounds are classified automatically using on-device machine learning (powered by Google's YAMNet model). Burrow also detects when you get into and out of bed, and compares each night against your historical sleep patterns so you can see whether last night was typical or unusual for you. On iOS, a paired Apple Watch adds live heart rate and additional motion data.

How does Burrow handle my sleep data?

Burrow keeps your sleep data on your device. Audio recordings, motion data, classified sound events, imported biometrics, and your full session history are stored locally — Burrow doesn't have a cloud copy of your nights and doesn't upload them. The only sleep data that leaves your phone is when you tap the AI summary or chat button: that sends aggregated trends from the night (counts, durations, totals — never raw audio, never individual event timestamps) to Anthropic's API to generate a response. Your name, if you've entered one, is included so the summary can address you. Separately, Burrow sends anonymized usage events and crash reports to our server so we can find bugs and prioritize improvements. None of that is your sleep data — it's feature counts and crash logs tied to a per-install identifier — and you can switch it off any time using the Help improve Burrow toggle in Profile. No third-party advertising SDKs, no cross-site tracking, no selling or sharing your data. See our Privacy Policy for the full breakdown.

How do I delete my data?

You can delete individual sessions from within the app. Deleting the app removes all locally stored data. On iOS, any data written to Apple Health must be deleted separately through the Health app. See the Account & Data Deletion page if you'd like written confirmation of removal.

Using Burrow

How do I start a sleep session?

Open Burrow on your phone before bed and start a session. Place your phone nearby while you sleep. Burrow will record and analyze your night, then present a summary when you wake up.

What do I see after a session?

Each session presents a full timeline combining audio events, motion, heart rate, and posture data in a single scrollable view. From there you can optionally request an AI-generated summary — tap the button to generate one. The summary covers how you woke up, whether that was earlier or later than usual, what was happening in your environment around wake time, and whether the circumstances suggest you're feeling more or less rested than usual.

What is the AI chat?

The AI chat lets you ask questions about your session grounded in your actual data — things like "what woke me up at 3am?" or "how does this compare to my usual sleep?" Like the AI summary, it only runs when you choose to use it. This feature is still early and largely untested, so treat the answers as a starting point rather than a definitive read.

Does Burrow work in the background while I'm asleep?

Yes. Burrow keeps recording audio and motion (and, on iOS, heart rate from a paired Apple Watch) through the night with your phone locked and the app in the background. Sound classification continues running while you sleep — only the live activity view in the app stops updating when the app isn't in the foreground, which is an OS-level limitation. Open Burrow in the morning to see the full classified timeline.

Does Burrow require an Apple Watch?

No. Burrow works as a standalone app using your phone's built-in microphone and motion sensors. An Apple Watch is optional — on iOS, if paired, the Watch runs a workout session overnight to keep heart rate streaming to your iPhone and can also start or stop a session independently.

Does Burrow work with Apple Health? (iOS)

Yes. On iOS, Burrow can read sleep-related biometrics from Apple Health after a session ends — HRV, blood oxygen (SpO2), respiratory rate, and resting heart rate when available. Burrow can also import the sleep stage data and night summaries written to Apple Health by other trackers (Apple Watch native sleep tracking, Oura, Whoop, etc.), so if you're already using a different device that writes to HealthKit, that data shows up alongside Burrow's own timeline. You control which data types Burrow may access through your iPhone's Health app permissions.

Is Burrow available on Android?

Burrow is available for both iOS and Android. Apple Watch integration and Apple Health sync are iOS-only features.

Subscription & Account

Is Burrow free? How does the subscription work?

There's a free tier that gives you the full sleep timeline, motion and posture tracking, on-device sound classification, and weekly insights — enough to use Burrow indefinitely without paying. Burrow Premium adds saved audio clips with playback and the AI summary and chat features. New subscribers get a 5-day free trial, then it's $5/month, $12 for 3 months, or $40/year. Your sleep data stays on your device either way; the subscription just unlocks features, not access to your own history. Free tier access can also be granted through a redeemable access code.

How do I manage or cancel my subscription?

Subscriptions are billed through the App Store (iOS) or Google Play (Android), and you manage them from the same place. On iOS, open Settings ▸ [your name] ▸ Subscriptions and pick Burrow. On Android, open the Play Store ▸ menu ▸ Payments & subscriptions ▸ Subscriptions. Cancelling takes effect at the end of the current billing period, and any local sleep data you've already recorded stays on your device.

Do I need an account or password?

No — Burrow works locally on your device without an account. Creating one is optional and mainly useful if you ever switch phones (so your settings and entitlements carry over), if you reinstall the app, or if you want a recovery path tied to your email. There's no cloud sync of your sleep data either way — your night history always lives on the device.

How do I reset my password?

Self-serve password reset isn't live yet. In the meantime, email hello@burrowsleep.com from the address tied to your account and we'll reset it manually within a business day.

Troubleshooting

I'm not seeing data after a session — what should I check?

A few common causes, in roughly the order to check them: (1) The background process is still our biggest rough edge. iOS and Android can kill long-running background apps under memory pressure, and Burrow's overnight tracking can end unexpectedly when that happens — usually the session will look paused or partial in the morning. We're actively hardening this but it's the most likely culprit if a night went missing. (2) Your phone's battery hit 0% before morning. (3) The Burrow app was force-closed (swiped out of the multitasking view) during the night, which ends the session. (4) Microphone or motion permissions were revoked — re-check Settings ▸ Privacy. (5) Apple Health permissions weren't granted, so biometrics show up empty on iOS. If you've checked all of the above and a session still looks wrong, email us — we read every report and missing-data complaints are how we find new edge cases.

I'm having issues with Apple Watch sync — is that expected?

Watch sync is functional but still early. You may run into issues if the Watch app goes to sleep or the phone and Watch lose their connection mid-session. If something looks wrong in the morning, the timeline will usually still have the phone-side data intact.
