Key features
Quiet Room is built around one idea: your ideal background sound is probably a mix, not a single track.

Email support →Last updated: August 25, 2026. This policy applies to the Quiet Room iOS application published by Mark Utility Labs.
Short version: Quiet Room generates every sound on your device and needs no account, and your mixes, settings and listening habits are never sent anywhere. What does leave the app is anonymous and technical: a crash report when the app crashes, and a count of how the unlock screen is used. No ads, no advertising identifiers, no tracking you across other apps or websites, and no sale of your data, ever.
Quiet Room stores your saved mixes, edits to the Popular section, selected theme, language, and sleep-timer preferences directly on your device using standard iOS local storage. None of it is ever sent anywhere, and neither is anything about which sounds you play.
All app data lives in local, on-device storage. Deleting the app removes all of it permanently — there's no cloud backup and no account to manage.
Quiet Room uses Firebase Crashlytics, a service run by Google, to report crashes automatically so bugs get found and fixed. When the app crashes, a report goes to Google containing the device model, the iOS and app version, the technical details of the crash, and a random identifier Firebase generates for your installation of the app. That identifier is not your name, your email, or your Apple ID; delete and reinstall the app and it changes. A crash report never contains your saved mixes, your settings, or anything about what you listen to.
When Quiet Room shows its unlock screen, it counts a short list of events through Firebase Analytics, also from Google: that the screen was shown, which layout was shown, and that an unlock completed. These events carry no personal content — none of your saved mixes, your settings, or anything about what you listen to, no name, no contact details. Quiet Room never attaches your identity to them; Firebase records them against the same kind of per-install identifier described above. They exist so we can tell whether the unlock screen works, and for nothing else.
Apple handles the transaction itself. Mark Utility Labs never sees or stores your card details, billing address, or Apple ID password.
Your unlock is kept on your device, in the iOS Keychain. If you unlock the whole collection of Mark Utility Labs apps at once, Quiet Room offers to safeguard that unlock so you can get it back on a new device — the only feature in the app that involves signing in anywhere. Only if you choose it, Quiet Room asks you to Sign in with Apple and stores a short record in Google Firestore, keyed to the identifier Apple returns: which unlock you hold and when you got it. Nothing else goes into it. Quiet Room never asks Apple for your name or email address, so we hold no way to connect that record to a real-world identity — but because it is keyed to your Apple sign-in it is a per-person record, and Apple's privacy labels for Quiet Room declare it as linked to you.
It's worth being explicit about the absences:
Google (Firebase) receives crash reports, the anonymous usage counts, and — only if you choose to safeguard an unlock — the unlock record. Apple handles the transaction and Sign in with Apple. There are no other recipients.
Quiet Room does not request access to your microphone, camera, location, contacts, or photos. It uses the standard iOS background-audio capability so your mix can keep playing when your screen is locked, and haptic feedback for taps — neither requires you to grant any permission.
Quiet Room is not directed at children under 13 and does not knowingly collect personal information from children. It never asks anyone, of any age, for a name, an email address, or any other identifying detail.
If this policy changes, we'll update the "Last updated" date above. Continued use of the app after a change means you accept the updated policy.

No company, no investors, no exit plan — just a retired dev, AI, and the growing conviction that this stuff should already cost almost nothing. I'm releasing a new app every week when the waves are bad and I'm not surfing.
Focus Hour
A to-do list, a day planner and a timer, because I kept losing track of all three.
Gym Log
Remembers what you lifted last Tuesday, so you don't have to.
Copy History
Your clipboard, but it remembers more than the last thing you copied.
Paper Scan
Paper goes in, a PDF comes out, and none of it leaves your phone.
SleepTracker
Tracks your sleep from your wrist or your pillow. No account, no nightly score to chase.
ZoneTime
Stops you cheerfully texting people at 4am their time.
Water Sort
Pour colors between bottles until they match. I lost a weekend to this one.
Cubby
A baby tracker built for 3am: dark, one-handed, no cheerful pastels.
Becoming
Affirmations over your own photos, read in your own voice.
