Privacy Policy
Moonsoon is designed to be private by default.
Last updated: October 9, 2026
Moonsoon ("we", "the app") helps you track your sleep and understand the sounds you make at night. We designed Moonsoon to be private by default.
The short version
- Moonsoon never uploads your audio recordings or your sleep data. Night-sound clips are recorded and classified on your device, and Moonsoon never uploads a clip. They stay in the app's local storage for your 7 most recent nights and are then deleted automatically — except a clip you choose to keep, which stays until you stop keeping it or delete your data; if clips take up a lot of space, older nights' clips may be removed sooner, but never last night's or a kept one. The clips you choose to keep are part of your device's own backup (iCloud or a computer, if you use one), so a device restored from it still plays them; every other audio clip is kept out of it. You can delete them yourself at any time: one recording, one night, or everything.
- "Show what you said" is optional and on-device. Only if you ask for it, sleep-talk clips are turned into text on your device with Apple's on-device speech recognition — never an online service. The text is stored with its night on your device — and, like the rest of your sleep data, in your device's own backup if you use one — stays after that night's audio is deleted automatically, and is removed with its recording or its night when you delete either, with all your data, or when you turn the feature off.
- We do not sell your personal data.
- We use a small number of third parties (below) for purchases, optional rewarded ads and optional Apple Health / Health Connect sync (writing the nights you track and, on iPhone, reading the sleep stages your Apple Watch or another wearable recorded and your Apple Watch's overnight vitals for them).
- A backup you make in Settings → Your nights is a file only you hold: your nights' numbers, notes and tags, and which clips you kept — no audio (not even a kept clip's), nothing read from Apple Health, and the words from your sleep talk only if you choose to include them. Moonsoon never sees or stores it anywhere else. Your device's own backup (iCloud Backup or a computer, if you use one) includes Moonsoon's local database, as it does any app's data — your nights, which clips you kept, any words from "Show what you said" and what Moonsoon read from Apple Health for them — and the clips you choose to keep, compressed, so a device restored from it still plays them. Every other audio clip is kept out of it. Moonsoon never uploads a clip: audio leaves your device only if you share a clip yourself or, for a clip you keep, in your device's own backup.
- A spreadsheet you export there (CSV) is the same kind of file: one row per night with its times, scores, snoring, breathing pauses, tags and how rested you felt — your notes only if you switch them on for that file. It never carries audio, the words from your sleep talk, or anything read from Apple Health. Moonsoon never sees it or keeps a copy.
- Ads are optional. No ad software starts until you say yes in the app, and Premium has no ads.
What we process
| Data | Why | Where it lives |
|---|---|---|
| Microphone audio during a sleep session | Detect & record snoring, sleep talking and other night sounds | On your device; the clips you keep also in your device's own backup — every other clip is kept out of it |
| Sleep sessions, scores, sound events | Your reports, trends and on-device insights | On your device (local database) |
| Text of your sleep talk (only if you turn on Show what you said) | Show what you said in the night's report | On your device (local database, with the night — so also in your device's own backup) |
| Purchase status (free / premium / lifetime) | Unlock features you bought | Apple App Store / Google Play |
| Advertising identifier and other device identifiers, coarse location, ad interaction, usage and performance data (only if you allow ads — see Third-party services) | Show an optional rewarded ad you chose to watch | Unity LevelPlay (ironSource) and Unity Ads |
| Sleep duration (optional) | Write to Apple Health / Health Connect if you allow it | Apple/Google Health, on your device |
| Your notes and your own tags (only what you write) | Remember what was different about a night; compare your tags with your snoring | On your device (local database and app settings — so also in your device's own backup) |
| Sleep stages from your Apple Watch — or from an Oura, WHOOP, Garmin, Withings or Ultrahuman device whose app writes them to Apple Health (optional) | Read from Apple Health, if you allow it, to show a night's stages on its report | On your device (local database, with the night — so also in your device's own backup); never in a Moonsoon backup file |
| Apple Watch overnight vitals: blood oxygen, respiratory rate, heart rate and Apple's breathing disturbances (optional) | Read from Apple Health, if you allow it, to show them on a night's report — and in the doctor PDF only if you leave them in and share it yourself | On your device (local database, with the night — so also in your device's own backup); never in a Moonsoon backup file or a shared picture |
We do not collect your name, email or account — Moonsoon has no login.
If you contact support from Help → Contact support, your email app sends us your message and your email address. Only if you switch on Include diagnostics does it also carry the app and iOS version, iPhone model, your plan, the number of tracked nights, notification status, recent error messages and, on iPhone and iPad, the battery and performance figures iOS measured for Moonsoon over the last week, one line a day: CPU time, time running in the background with audio (which shows roughly how long Moonsoon listened, or played a sleep sound, that day), disk writes, launch time, hangs and how often iOS closed it in the background. Never audio, recordings or what a night held — its sounds, words, scores, stages or notes. You see all of it before you send. We use it only to answer you. Those figures are kept on your device for two weeks and Moonsoon sends them nowhere else.
Reminders and summaries (bedtime nudges, the weekly recap) are scheduled on your phone. Nothing about them is sent to a server, and you can turn each one off in Settings → Notifications.
Microphone
Moonsoon only listens while a sleep session is active (you start it manually). Audio is analyzed on-device, and Moonsoon never uploads a clip: audio leaves your device only if you share a clip yourself or, for a clip you keep, in your device's own backup. You can delete one recording (••• next to it on its report → Delete this recording), one night (••• at the top of its report → Delete this night), or all recordings and sessions any time from Settings → Privacy → Delete all sleep data.
Deleting one night removes its numbers, every clip from it (kept ones too) and any words from it; deleting one recording removes its audio and keeps only the night's numbers. A night Moonsoon already wrote to Apple Health stays there until you delete it in the Health app.
What you said (speech recognition)
If you tap Show what you said on a report, Moonsoon turns that night's sleep-talk clips into text — only clips you can play, and only after iOS has asked you for permission to use speech recognition. The text is made on your device: Moonsoon uses Apple's on-device speech recognition only, so the audio is not sent to Apple or anyone else. (iOS's own permission prompt describes speech recognition in general, including its online kind, which Moonsoon never uses.) If your device can't recognise your language on the device, Moonsoon says so and makes no text.
The text is stored with its night in the app's local database. It is kept after the clip's audio is deleted automatically — a short line of text is the part of an old night worth keeping — and it is deleted with its recording (Delete this recording), with its night (Delete this night), with Delete all sleep data, or all at once when you turn off Settings → Privacy → Show what you said. Moonsoon never sends it anywhere: it leaves your device only in your device's own backup, like the rest of your nights, in a picture of a night you share if you add it, after a confirmation that says so, or in a backup file you make if you switch the words on for it.
Ads
Moonsoon's free version can offer a short rewarded ad that you choose to watch — for example to hear one more night-sound clip, use a Premium sleep sound for one night, or open detailed trends until tomorrow. There are no banners and no ads you didn't ask for. The first time you tap one of these offers, Moonsoon asks whether you allow ads; no ad software starts before you answer yes. Only after that, on iPhone, Apple may show its own "Allow tracking" prompt — you can say no and still watch the ad. Premium and Lifetime have no ads. Your recordings and sleep data are never shared with ad partners, and Moonsoon never sends them anywhere: they leave your device only if you share them yourself, or — your sleep data and the clips you keep — in your device's own backup. The same goes for the text of what you said.
Third-party services
- Apple App Store / Google Play — process purchases and manage your subscription / lifetime entitlement (in-app purchase via StoreKit / Play Billing).
- Unity LevelPlay (ironSource) and Unity Ads — show the optional rewarded ads, and only after you allow ads. They use what they collect to pick, deliver, measure and protect ads and to improve their software; Unity links some of it to your device. According to their answers to Apple's privacy questions:
- ironSource (LevelPlay): your device's advertising identifier, product interaction, advertising data and performance data.
- Unity Ads: coarse location (your country), a user ID, your device's advertising identifier, purchase history, product interaction, advertising data, other usage data, performance data (such as how fast the ad software starts) and other data such as your device's language, make, model, screen size and connection type.
- Apple HealthKit / Android Health Connect — only if you grant permission; we write the sleep we track and, on iPhone, read the sleep stages your Apple Watch — or an Oura, WHOOP, Garmin, Withings or Ultrahuman device, through its app — recorded for the nights you tracked, and the overnight vitals (blood oxygen, respiratory rate, heart rate and Apple's breathing disturbances) your Apple Watch recorded for them. We read no other health data, and Moonsoon never sends what it reads anywhere — not to our servers, not to anyone. It is kept with your nights in the app's local database (so, like them, in your device's own backup), never in a Moonsoon backup file or a shared picture; the vitals go into a doctor PDF only if you leave them in and share it yourself.
Your choices
- Decline microphone, speech recognition, Health or tracking permissions at any time in system settings.
- Turn Show what you said off in Settings → Privacy; that deletes every transcript Moonsoon made (your clips stay). If it is already off and some nights still keep words, Delete what you said there does the same. Neither needs speech recognition, or a device that can still do it.
- Turn ads off, or back on, at any time in Settings → Privacy → Ads & privacy. Turning them off withdraws your consent from the ad partners and stops ad requests.
- Delete one recording or one night from its report, or everything in Settings → Privacy → Delete all sleep data; uninstalling removes all local data. A night already written to Apple Health / Health Connect stays there until you delete it in that app.
Children
Moonsoon is not directed at children under 13.
