Last updated 1 September 2026 — what changed: 20 August, PostHog added as our analytics processor; 1 September, RevenueCat named, the "Write to us" channel and retention periods added, and the wording on what travels with your photo made exact.
Your bedroom photo is sent to be analysed only if you tap to allow it, and only after you subscribe. Your answers, your name, your email and your location never leave your phone — we do not have them, and there is no account to create. What does leave your phone: anonymous usage events, the anonymous subscription receipt that Apple issues (handled for us by RevenueCat), and any message you choose to write to us. We do not sell anything to anyone, and we do not track you across other apps or websites.
When you photograph your bedroom, or pick a photo from your library, that image is stored on your device, inside the app's own storage. Deleting the app removes it.
To score your room, that one image is sent to Google's Gemini API. This happens only after two things are true: you have subscribed, and you have tapped to allow it on a screen that explains exactly this. If you decline, you still get your Sleep Score — it is simply calculated from your twelve answers alone.
If we ever change what is sent or who receives it, this page changes first.
The twelve questions you answer are stored on your device, alongside your Sleep Score, your nightly checklist and the nights you logged. They stay on your phone. They are not sent to us and they are not linked to your identity, because we never learn your identity.
The app records anonymous events about how it is used — for example that a screen was opened, that the quiz was completed, or that a subscription screen was dismissed. We use them to find the places where the app confuses people.
Each event carries: the event name, a timestamp, the app version, the platform, and a random identifier generated on your device the first time you open the app. That identifier is not your Apple ID, not your advertising identifier, and not tied to anything else about you. Deleting the app deletes it from your phone; the events already sent stay on our side under that identifier until they are deleted (see How long we keep things below). Our analytics provider also attaches to each event the standard fields of its SDK — the device model, the iOS version, the language, the time zone and the screen size. None of them identifies you.
Some events also carry your Sleep Score — the number out of 100 — because we need to know whether people with a low score behave differently from people with a high one. That number describes a bedroom, not a person. Purchase events additionally carry which plan was bought and what Apple charged for it, so we can tell a weekly subscriber from a yearly one. A few events carry small counters — how many checklist items were ticked, how long a reading took — never the content of anything you typed, answered or logged.
These events never contain your photo, your twelve answers, your name, your email address or your location.
Three companies, and nobody else:
None of them is allowed to use your data for their own purposes. PostHog and RevenueCat never receive your photo. Supabase hosts the small server function that relays it to Google: the image passes through that function in memory and is never stored or logged there. Google receives the photo, as described above, and nothing else.
The app has a Write to us screen. If you use it, we store the message you type (up to 2,000 characters) together with your Sleep Score, your protocol night, whether you are subscribed, your installation identifier, the app version and the platform, in our Supabase database. Only the founder reads it. Do not include anything you would not want stored — and if you did, ask and it is deleted.
If you join the early-access list on this site, we store the email address you type, the date, and a short label saying which link brought you here. We use it once — to tell you when the app is out. Reply to that email asking to be removed and we will delete the address.
The site uses Vercel Web Analytics, which counts visits without cookies and without building a profile of you.
SleepAudit AI is not directed at children under 13, and we do not knowingly collect information from them.
Because we hold almost nothing about you, most requests are simple: deleting the app deletes everything stored on your device. For the anonymous usage events, write to us and we will delete the records tied to your installation identifier, which you can find in the app under Me. For your email address on the early-access list, ask and it is removed.
If you are in the EU or the UK, you have the right to access, correct, delete and port your data, and to complain to your local data protection authority.
If this policy changes in a way that affects what we collect, we will update the date at the top and say what changed. We will not start collecting something new and quietly backdate it.
