Privacy Policy

WaveSleep · Alpha Original LLC

Last updated 24 September 2026

WaveSleep is built to need as little of your data as possible. There is no account, no sign-in, and nothing to log in to. Almost everything the app knows about you stays on your device.

What stays on your device

All of this is stored locally, in the app's own storage, and is never sent to us:

• Your mixes — which sounds you combine, their levels, tone and swell, and the names you give them.
• Your settings — theme, haptics, night sky, wake time, wake sound and wake volume.
• Your sleep journal — for each night: the date, how you rated it, how you said you were arriving at the evening check-in, which sounds were playing and at what levels, when playback started and stopped, whether a timer completed, how many times playback was interrupted, and how long you kept adjusting things before settling.
• An approximate location, only if you turn the night sky on and grant permission. See below.
• Sleep Apple Health has measured, only if you connect Health from the Insights screen. See below.

Deleting the app deletes all of it. We have no copy and no way to recover it.

Location

If you enable the night sky, WaveSleep asks for location so it can draw the sky and the sunrise for roughly where you are.

• It requests reduced accuracy and then rounds the result to one decimal place — about 11 kilometres. It never has, and never asks for, your precise position.
• The rounded coordinate is stored on your device and is never transmitted anywhere.
• You can decline. The night sky still works; it just won't match your location.

Apple Health

WaveSleep can show you how long you actually slept beside the nights you used a sound. It only ever does this if you ask it to.

• It is opt-in, from a button on the Insights screen. The app never asks at launch, and if you never tap it the app never touches Health at all.
• It reads sleep analysis only — nothing else in Health, and only from roughly the last month. Each night also keeps the name of whichever device recorded it, usually "Apple Watch", so Insights can say where the figure came from.
• It never writes anything to Health. WaveSleep has no permission to, and asks for none.
• What it reads is stored on your device, in the same sleep journal as everything else, and is never transmitted anywhere. In particular it is never sent to PostHog: none of the analytics events below carry anything derived from Health.
• You can revoke it at any time in the Health app → Sharing → Apps → WaveSleep. The rest of Insights carries on working.

Anonymous usage analytics

WaveSleep sends a small number of anonymous events to PostHog (servers in the United States) so we can see which features are used and whether things are breaking.

• There is no account, no advertising identifier, no IDFA, and no App Tracking Transparency prompt, because we do not track you across apps or websites.
• Events are identified only by a random identifier PostHog generates on the device.
• We do not send your mix names, your journal, your location, your contacts, or anything you type.

The events are: opening the app; starting or pausing playback; setting a timer; saving or reverting a mix; downloading a sound; showing the paywall; completing a purchase; changing theme; toggling the night sky; the alarm ringing, being snoozed or stopped; audio errors and route changes.

Every event also carries basic technical context: the app version, your iPhone model, the iOS version, your language and time zone, whether you are on Wi-Fi or cellular, and the screen size. None of it names you or your device — the model is "iPhone", not whatever you called it.

Crash and error reports

If WaveSleep crashes, it writes a crash report on your iPhone and sends it to PostHog the next time you open the app. Separately, when something fails that you might not notice (the sound stopping after your headphones connect, say, or the alarm failing to arm), the app sends a short error report. Each report contains the kind of failure, where in WaveSleep's code it happened, the technical context above, the audio output type (for example "Bluetooth" or "AirPlay", never your device's name), and a short list of the app's own recent steps, such as "audio route changed". Reports go to the same anonymous identifier and contain nothing from your journal, your mixes, Health, or anything you typed. We use them only to find and fix bugs.

One of these deserves to be called out plainly. When you complete a check-in, we send the event `checkin_logged` together with the number you chose — your sleep rating in the morning, or how you said you were arriving in the evening. That is self-reported sleep information leaving your device. It is a bare number attached to an anonymous identifier, with no name, no date-stamped history and nothing else from your journal, but we would rather say so than let you discover it.

Purchases

WaveSleep Plus is sold through Apple. Apple handles the payment; we never see your card, your Apple Account, or your billing details. We record only that a purchase completed, and which of the two plans it was.

Sounds downloaded after install

The recorded nature sounds are hosted by Apple and downloaded when you first use them, so the app installs small. Those requests go to Apple, not to us.

Notifications and alarms

The morning check-in reminder and the wake alarm are scheduled on your device, by iOS. Nothing about them is sent to a server, and no push notifications are used.

What we never do

We do not sell your data. We do not share it with advertisers. There are no third-party advertising or tracking SDKs in the app. We do not build a profile of you, and we could not identify you from what we receive.

Children

WaveSleep is not directed at children under 13 and we do not knowingly collect information from them.

Your choices

• Delete everything: uninstall the app.
• Turn off location: iOS Settings → WaveSleep → Location.
• Turn off Apple Health: the Health app → Sharing → Apps → WaveSleep.
• Ask about analytics: because events are anonymous, we usually cannot find "your" data — there is nothing tying it to you. If you can give us the identifier, we will delete what we can.

Changes

If this policy changes we will update the date above and the copy inside the app.
