Privacy Policy
Last updated : 2026-08-28
Hoot is an iPhone app that records the sounds of your night. This policy explains plainly what data exists, where it lives and who can access it. In one sentence: your recordings and your history stay on your iPhone.
No account, no sign-up
Hoot asks for no email address, no password and no phone number. You have no account with us, so we hold no profile about you.
What stays on your device
The following is stored in the app's private space on your iPhone and is never transmitted:
- the audio clips captured during your nights;
- your label corrections, with a copy of the corrected clip (up to 100, deletable at any time, shared only by your own gesture);
- your night history, scores and statistics;
- the sleep stages estimated by the app;
- your settings (reminder times, language, appearance);
- your answers to the questions asked on first launch.
The microphone
The app requests microphone access to listen to your night. All analysis (snoring and speech detection, sleep-stage estimation) runs entirely on your iPhone, with no internet connection. No audio clip is sent to any server, to us, to a third-party provider, or to any artificial intelligence service.
You can withdraw this permission at any time in Settings > Privacy & Security > Microphone. The app will then stop recording.
People sleeping near you
The microphone captures everything audible, including another person in the room. You are responsible for informing that person before recording. In several countries, recording someone without their consent is illegal. The app reminds you of this before your first night.
Health app data (HealthKit)
If you allow it, Hoot reads your sleep stages from Apple's Health app in order to compare them with your night sounds. This access is read-only: Hoot writes nothing into your Health record.
In line with Apple's rules, this data never leaves your device, is never used for advertising or marketing, and is never sold. You can revoke access in Health > Sharing > Apps.
Third parties actually used
Hoot only works with the following providers: Apple, RevenueCat, Vercel, TelemetryDeck, Expo. No others.
- Apple: app distribution and payment processing. We never see your payment details; Apple only shares aggregated sales data with us.
- RevenueCat: subscription state management. This service receives an anonymous identifier generated by the app and the purchase receipt provided by Apple. It receives no audio recording, no sleep data, no health data and nothing that identifies you.
- Vercel: hosting of this website. Like any host, it technically logs visits (IP address, page viewed) to operate and secure the service. Those logs concern the website, not the app.
- TelemetryDeck (TelemetryDeck GmbH, Augsburg, Germany — data hosted in the European Union): anonymous, aggregated usage statistics for the app. The app sends it events without any identifier (for example "app opened", "clip shared as video", "clip duration"), together with the app version, OS version and device model, with a timestamp rounded to the hour. No IP address is stored, no cookies, no audio recording, no sleep or health data. This data is used solely to understand which features are used, overall — never to follow a person.

- Expo (650 Industries, Inc., United States): delivery of app fixes. Each time you open the app, it asks this service whether a fix is available to download — a wording to correct, a display bug to repair — so you get it without waiting for a new version on the App Store. The request states the app version and the platform (iOS), nothing else: no identifier, no audio recording, no sleep or health data. As with any request over the internet, the service sees the connection's IP address. This mechanism only repairs what already exists — it never adds a feature Apple has not reviewed.

What we do not do
Stated explicitly, because these are the industry's most common practices:
- no advertising trackers, no ad network, no ads in the app;
- no audience measurement that could identify you: the usage statistics described above are anonymous and aggregated, with no identifier and no IP address;
- no selling, renting or trading of data;
- no profiling, no automated decisions about you;
- no sending of your recordings to any artificial intelligence service.
Notifications
If you enable the bedtime reminder, the app schedules a local notification on your iPhone. It is generated by the device: no notification server is involved, and we do not know whether you received it.
Retention and deletion
Your recordings stay on your iPhone until you delete them. The app automatically erases nights too short to be meaningful. You can erase everything at once in Settings > Your data > Erase all my nights — this also erases your kept corrections, which additionally have their own delete button in Settings. Deleting the app also erases all of this data.
Your rights
European regulation (GDPR) grants you rights of access, rectification, erasure and portability over your personal data. Because we hold no personal data about you, these rights are exercised directly from your iPhone: the data is with you, and only you can access or delete it.
For any question, write to support@hootnights.com.
Children
Hoot is not intended for children under 13 and knowingly collects no data about them.
Changes
If this policy changes, the date at the top of the page is updated. A change that would broaden the use of your data would be announced in the app before taking effect.
