Which Snoring Apps Collect Your Data? 14 Privacy Labels (2026)

What an App Store privacy label is

Every app on the App Store carries an App Privacy section on its listing. Apple calls it privacy information. Most people call it the privacy nutrition label. The developer fills it in by answering Apple’s questionnaire in App Store Connect, and the App Store turns the answers into up to three boxes [1].

The three tiers

• Data Used to Track You. Data the app links with data from other companies’ apps, websites or offline properties for ads, or shares with a data broker [2].
• Data Linked to You. Data tied to your identity “via their account, device, or other details” [1].
• Data Not Linked to You. Data the developer collects after stripping identifiers. Apple’s support page says a developer must use protections “such as stripping any direct identifiers, for example user ID, before collection” [2].

When a developer declares nothing in any tier, the listing shows a single box instead: Data Not Collected, with the line “The developer does not collect any data from this app.”

What “track” means to Apple

Apple’s definition is narrow. Tracking “refers to linking data collected from your app about a particular end-user or device, such as a user ID, device ID, or profile, with Third-Party Data for targeted advertising or advertising measurement purposes, or sharing data collected from your app about a particular end-user or device with a data broker” [1]. Analytics a developer keeps in-house does not count as tracking. An app can declare a long list of data linked to you and still show no tracking box.

The detail behind each box

Each box lists categories, such as Identifiers or Health & Fitness. Tap See Details and the label breaks every category into data types, such as User ID or Audio Data, grouped by purpose, such as Analytics or App Functionality. We quote that detail for every app below. Apple also lets a developer leave out a data type when it meets every item on a short list, such as collection that is optional, infrequent and started by you [1].

All 14 apps at a glance

The table shows each tier as declared on the App Store on 27 September 2026, with the rating, rating count and the price range of anything the listing sells. We checked the US store for all 14 on the same day.

Two apps list no purchases at all: Snore Timeline and Snore Recorder - Sleep Monitor. Of those two, Snore Timeline declares Data Not Collected, and Snore Recorder - Sleep Monitor declares data not linked to you.

Apps that declare Data Not Collected

Four of the 14 labels show the Data Not Collected box. The four differ in how they charge you, and that difference is where Snore Timeline stands apart.

Snore Timeline

Snore Timeline’s listing shows a free download with no in-app purchases. It holds a 4.9 rating from 214 ratings [4]. It is the only one of the 14 apps with both an empty label and no purchases of any kind.

AutoSnore

AutoSnore costs $4.99 up front and lists no in-app purchases [5]. Its listing says it comes from the team behind AutoSleep and promises “No subscriptions. No hidden extra In App Purchases.”

SnoreClock

SnoreClock is a $9.99 one-time purchase with no in-app purchases [6]. Its listing says it records up to 11 hours and marks talking, whispering and coughing next to snores.

Somnio+

Somnio+ is a free download that sells weekly subscriptions at $4.99 and $9.99 and annual ones at $14.99 and $29.99 [7]. Its listing says it marks long silent periods as possible breathing pauses and states that it is not a medical device.

Apps that declare data linked to your identity

Eight apps list at least one category under Data Linked to You. The data types below come from the See Details view of each label. They describe what the developer declared. They say nothing about where the data sits or which servers handle it, and we make no guess about that.

SnoreLab

SnoreLab is the snore app with the Snore Score and remedy tracking [8]. Its label lists Health & Fitness, Contact Info, User Content and Identifiers as linked to you. In the detail, the developer declares Health for Analytics and Product Personalization, and Email Address, Audio Data, Customer Support and User ID for App Functionality. Device ID, Product Interaction and Crash Data sit under Data Not Linked to You, and Usage Data appears under Data Used to Track You.

Sleep Cycle

Sleep Cycle built its name on the smart alarm. Its label lists seven categories as linked to you: Health & Fitness, Purchases, Location, Contact Info, Identifiers, Usage Data and Diagnostics. The detail names Health, Purchase History, Coarse Location, Email Address, Name, User ID, Device ID, Product Interaction and Crash Data. Coarse Location, Email Address, Name, User ID and Device ID also appear under Developer’s Advertising or Marketing. The label declares no Audio Data.

Pillow

Pillow goes deep on Apple Watch sleep tracking and carries an Editors’ Choice badge. Its linked data is short: Device ID, Product Interaction and Crash Data, declared for Analytics and App Functionality. Purchase History, Coarse Location, Customer Support and User ID sit under Data Not Linked to You. The label shows no tracking box and declares no Audio Data.

ShutEye

ShutEye pairs a large sound library with snore and sleep-talk recording [9]. Its linked data is User ID and Device ID, both declared for Analytics. Health and Audio Data appear under Data Not Linked to You for App Functionality, next to Product Interaction, Other Usage Data, Crash Data and Performance Data. Identifiers also appear under Data Used to Track You.

BetterSleep

BetterSleep is a sound and relaxation app [10]. Its label lists seven categories as linked to you. The detail names Purchase History, Email Address, Name, User ID, Device ID, Product Interaction, Other Usage Data, Customer Support, Other User Content, Crash Data and Other Data Types. Precise Location and Performance Data sit under Data Not Linked to You. Four categories appear under Data Used to Track You, the longest tracking list of the 14.

SleepScore

SleepScore’s listing describes a sonar sleep tracker that measures your sleep from the nightstand without contact. Its label lists seven categories as linked to you. The detail names Health, Fitness, Purchase History, Precise Location, Email Address, Name, User ID, Device ID, Product Interaction and Other Data Types. The developer declares Precise Location for Analytics and Product Personalization. Crash Data and Performance Data sit under Data Not Linked to You, and the label shows no tracking box.

Snollo

Snollo classifies sounds on the device with Core ML and adds sleep stages from Apple Watch. Its label lists six categories as linked to you. Under App Functionality the detail names Precise Location, Name, Audio Data and User ID, plus Health, Fitness and Purchase History. Product Interaction, Crash Data and Performance Data sit under Data Not Linked to You. The label shows no tracking box.

Snore Control

Snore Control’s listing says it detects snoring with a machine learning model and offers a function that tries to stop your snoring. Its linked data is a single item: Customer Support, declared for App Functionality. Product Interaction and Crash Data sit under Data Not Linked to You. Of the eight apps in this group, it declares the fewest linked data types.

Apps that declare Data Used to Track You

Four apps show the tracking box, as declared on the App Store on 27 September 2026:

• SnoreLab: Usage Data.
• Sleep Cycle: Identifiers.
• ShutEye: Identifiers.
• BetterSleep: Purchases, Identifiers, Usage Data and Other Data.

Apple’s user-facing page explains the box this way: data “linked with your data collected from other companies’ apps, websites, or offline properties, and used for ads or shared with a data broker” [2]. Its examples include an app showing targeted ads based on data from other companies’ apps and websites, and an app sharing advertising IDs with an ad network that retargets you in other apps.

The tracking box lists categories only. It does not name a purpose or a partner, so the label alone will not tell you which ad network receives the data. The developer’s privacy policy, linked from the listing, is the place to look. The other ten apps declare no tracking.

Apps that declare only data not linked to you

Two apps collect data by their own declaration but keep all of it out of the linked and tracking tiers.

Koala Nap

Koala Nap’s listing says it nudges you when you snore through Apple Watch vibrations, iPhone alerts or Bluetooth earphones. Its label declares Audio Data and Crash Data, both for App Functionality and both not linked to you. It sells monthly and yearly subscriptions from $6.99 to $39.99.

Snore Recorder - Sleep Monitor

Snore Recorder - Sleep Monitor’s listing describes AI detection of snoring, talking and shouting, plus AI-generated soundscapes. Its label declares Audio Data for App Functionality and Product Interaction for Analytics, both not linked to you. The listing shows no in-app purchases, which makes it the other app of the 14 with no purchases. Its label is what separates it from Snore Timeline.

What each privacy policy says about selling and sharing

A label is one line per data type, written by the developer. The privacy policy is the longer document the label links to. We read each app’s policy on 27 September 2026 and pulled out three things: what it says about selling, which companies it names as receiving data, and what it says about recordings and health data. Every quote below comes from the live page on that date.

A policy describes what a company intends. It cannot show what an app transmits. A network capture of the running app can. One term needs a note. California law gives “sell” and “share” a legal meaning. The California Attorney General’s CCPA page says “sharing refers specifically to sharing for cross-context behavioral advertising” [26]. That covers passing data to an ad network, with or without payment.

Snore Timeline’s own privacy policy, last updated 17 May 2026, says the app has “no account, no sign-in” and that recordings are “created, processed, and stored exclusively on your device.” It does not mention selling.

SnoreLab

The SnoreLab policy page [11] carries two notices, marked “Last updated: Jul 2, 2025” and “Last updated: September 18, 2026”. We quote the 2026 notice. Section 4, “Who we disclose your data to”: “Except as described in this section, we will not disclose or sell any of your personal data to third parties, unless you have given us explicit consent to do so.” The AppsFlyer row says: “This allows us and third parties to track your activity across apps and websites.” Section 2 lists audio recordings as “Only collected by us if you have subscribed to Cloud Backup or opted in to research.” The AWS row lists Apple Health data for “Research and development, including improving detection algorithms”.

Sleep Cycle

The Sleep Cycle privacy policy [12] shows no date. It does not mention selling. The section “How we share your personal data and who we share it with” names Google Cloud, Amplitude, Amazon Web Services, Mailgun, Leanplum, Zendesk and Fivetran. Under “The Sleep Cycle app privacy notice”: “As a default setting, personal data related to your health will only be stored locally on your device.” Under “Store your sleep data on our servers”: “We will store all the data available in the app on our secure servers, hosted by Google Cloud.” The policy mentions marketing email and no ad networks. Sleep Cycle’s App Store label declares Identifiers under Data Used to Track You.

Pillow

The Pillow policy page [13] combines its Terms of Use and Privacy Policy. The date under the Terms of Use heading reads “Effective Date: 2026-09-08” in the desktop layout and “Effective Date: 2025-09-06” in the two smaller-screen layouts. The privacy section shows no date of its own. Under “Summary of Key Points”: “We do not sell your data.” Its Do Not Sell page [14] says: “Neybox Digital Ltd. does not sell Personal Information.” “Third-Party Processors and Transfers” names the companies listed in the table above. The policy says: “We use Adjust to share pseudonymous device IDs with Meta and Google.” Under “Your Health Data Stays Private”: “All sleep tracking, health metrics, and audio analysis occur exclusively on your device.”

ShutEye

Enerjoy, the developer, publishes two documents.

The 2026 policy names Facebook, Firebase, Google, AppsFlyer and OpenAI, and IKEA for users who join a collaboration. It describes “‘interest-based’ or ‘personalized advertising,’ including through cross-device tracking.” Under “How We Disclose Your Information”: “We will not share Health Data with Advertising Partners (defined below) under any circumstances.” The policy does not mention audio or recordings.

BetterSleep

The BetterSleep privacy policy [17], “Last updated : May 11, 2026”, names BetterSleep Health, LLC. Section 14C, “‘Sale,’ ‘Sharing’ and Personalized Ads”: “We do not sell personal information to Third Parties in exchange for money.” It adds that “Our use of ad networks” “falls within these broader definitions”, and lists Identifiers, Commercial Information, Internet Activity, Geolocation and Inferences as the categories. Section 10 says these networks “track individuals’ online activities over time”. The policy names OpenLoop for clinical services. The opt-out page [18] names Facebook Custom Audience, Conversion Tracking Pixels and Google Analytics. Section 3: “We store that data derived from the recordings (but not the recordings themselves)”.

SleepScore

The SleepScore app privacy policy [19] shows “Version: 1.5.0” and “Updated: 9th March 2026”. The policy link on the App Store listing redirects to the website policy at sleep.ai/privacy-policy. The app policy opens: “We do not and will not sell your data to third parties.” Under “How and Why We Collect and Use Personal Data”: “SleepScore does not sell your data to advertisers”. It names no companies. On audio: “Audio events are classified as events above a certain threshold and stored as timestamps, no recognisable audio is collected or stored”. On models: “we use sleep data and demographics to improve the relevancy” of its advice “by training sleep models and algorithms”. Data is “stored and processed in the United States”.

Snollo

The Snollo privacy policy [20] is marked “Effective: May 27, 2026”. Under “Your rights”: “Snollo does not sell or share your personal data for cross-context behavioral advertising.” Under “Third-party services we use”: “We have no data-selling relationships with anyone.” That section names Apple services, Mixpanel, PostHog, TelemetryDeck, Sentry, RevenueCat and Ahrefs. Mixpanel receives “event names and your User ID; never sleep data, audio, or name”. Under “Microphone”: “Only the resulting classifications and brief clips are saved … to your private iCloud”.

Koala Nap

The policy link on the App Store listing opens koalanap.com/privacy-policy [22]. On 27 September 2026 that page showed the heading “Privacy Policy” and no body text. A second document at flycricket.io/koala-nap [23] shows no date and says it was “modified/generated by App Privacy Policy Generator”. It may not be the current policy. It does not mention selling. It names Firebase Analytics, Fabric, Crashlytics and Flurry Analytics. Under “Audio recording”: “The recordings may be sent to our servers for further analysis and ML model training.” It says uploading “can be disabled in the apps settings.”

Snore Control

The Snore Control privacy policy [24] is marked “Last updated: October 1, 2020”. It describes the app as “a Freemium app and as an Ad Supported app”. It names AdMob, Firebase Analytics and Firebase Crashlytics. The policy does not mention selling personal data in general. Its Apple Health paragraph says: “We will not sell your Health Data to advertising platforms, affiliate networks, data brokers or information resellers.” The same paragraph says: “Your health data will not be sent to any external server”. The policy does not mention audio or recordings.

Snore Recorder - Sleep Monitor

The policy link on the App Store listing opens a Google Doc [25] titled “Privacy Policy - Sleep Monitor: Snoring Tracker”. The document shows no date. It does not mention selling. It names Firebase as an analytics provider. Under “Transfer Of Data”, it says “we transfer the data, including Personal Data, to Republic of Azerbaijan and process it there.” The document does not mention audio, recordings or health data.

Read your own copy

Policies change, so read the one that applies on the day you install. Open the app’s App Store listing and tap the developer’s privacy policy link. Search the page for “sell”, “share”, “third” and “advertis”, then for “audio” or “recording”. Note the date at the top. If the page shows more than one date, or the link opens an empty page, write to the developer and ask which version applies.

What a label cannot tell you

A privacy label is a declaration, and Apple says so. Its support page calls it a system “where the information is self-reported by the developer” [2]. The developer page puts the duty on the developer: “You’re responsible for keeping your responses accurate and up to date. If your practices change, update your responses in App Store Connect. You may update your answers at any time, and you do not need to submit an app update in order to change your answers” [1].

Every label on the App Store also carries this line: “Privacy practices may vary, for example, based on the features you use or your age.” Apple’s support page adds that data collection can differ between free and paid versions, between regions, and with how you use the app [2].

Researchers have tested labels against app code. A 2023 USENIX Security paper analyzed the privacy labels and app binaries of 5,102 iOS apps and reported cases where a label did not match the data flows the tools found [3]. That study did not examine the apps on this page. It shows why a label is a starting point, and why the developer’s privacy policy is worth a read before you trust an app with a night of audio.

Check a label yourself in 20 seconds

1. Open the app’s page in the App Store app.
2. Scroll down to App Privacy. The boxes show the tiers and categories.
3. Tap See Details for each data type and the purpose the developer gave for it.
4. Tap the privacy policy link on the same screen if a data type needs explaining.

Do this on the day you decide. A developer can change the answers without shipping an update, so the labels on this page describe 27 September 2026 and nothing later. We re-check labels on the date shown at the top.

Why Snore Timeline’s label is empty

Snore Timeline declares Data Not Collected because the app has nothing to send the developer. It has no account and no sign-up. It has no server of its own. It ships no analytics SDK or third-party tracker. It sells nothing, so there are no in-app purchases and no purchase history to record.

The audio analysis runs on the phone. Recordings, episode data and sleep stage estimates stay in the app’s storage, where you set a cap between 1 and 8 GB (see storage and quality). Nothing leaves the phone unless you export it yourself: CSV reports, episode clips or full-night audio go to the Files app, and from there to your doctor or anyone you choose (see export and sharing). The full policy is at snoretimeline.com/privacy.

An empty label comes with a trade-off. No account means no cloud backup and no sync between devices. If you delete the app, the recordings go with it unless you exported them first.

Frequently asked questions

Do snoring apps upload my recordings?

The privacy label cannot answer that on its own. A label lists the data types a developer declares it collects. It does not say where the data travels or where it is stored.

As declared on the App Store on 27 September 2026, five of the 14 apps list Audio Data. SnoreLab and Snollo list it as linked to you. ShutEye, Koala Nap and Snore Recorder - Sleep Monitor list it as not linked to you. The other nine declare no Audio Data. For the full picture, read each developer's privacy policy, which the listing links to.

Which snoring apps have a Data Not Collected label?

Of the 14 apps we checked on the US App Store on 27 September 2026, four show Data Not Collected: Snore Timeline, AutoSnore, SnoreClock and Somnio+.

Snore Timeline is the only one of the four with no purchases of any kind. AutoSnore costs $4.99 once, SnoreClock costs $9.99 once, and Somnio+ sells weekly and annual subscriptions.

Is the App Store privacy label verified by Apple?

Apple describes the program as one “where the information is self-reported by the developer.” Its developer page adds: “You’re responsible for keeping your responses accurate and up to date.”

Apple sets the definitions and the questions. The developer supplies the answers and can change them at any time without an app update.

Does a subscription change what an app collects?

A subscription can add a category to the label. Apple lists Purchases, with Purchase History as its data type, as a category a developer declares when it collects your purchase records.

On 27 September 2026, Sleep Cycle, BetterSleep, SleepScore and Snollo declared Purchases as linked to you, and BetterSleep also listed Purchases under Data Used to Track You. Pillow listed Purchase History as not linked to you. Somnio+ sells subscriptions and still declares Data Not Collected.

How do I check an app's privacy label myself?

Open the app's page in the App Store and scroll to App Privacy. The boxes show the categories. Tap See Details to see each data type and the purpose the developer gave for it, such as Analytics or App Functionality.

Do it on the day you decide to install. A developer can change the answers in App Store Connect without shipping an update, so a label from last month may not match today's.

Do snoring apps sell your data?

None of the ten app privacy policies we read on 27 September 2026 says the company sells data for money. BetterSleep says its use of ad networks counts as a sale or share under California law. Sleep Cycle, Koala Nap, Snore Control and Snore Recorder - Sleep Monitor do not mention selling personal data in general.

SnoreLab, Pillow, SleepScore and Snollo say they do not sell. ShutEye's app policy says Enerjoy does not sell, and a 2024 Enerjoy policy for its website says it may have sold or shared some categories. A policy describes intent. Only a network capture shows what an app sends.
