Privacy Policy

Last updated: 20 August 2026

Hotel Sentry is built so that the developer never receives your data. There is no Hotel Sentry server, no account to create, and no analytics or advertising code in the app.

What we collect

Nothing. We operate no servers and have no ability to see your devices, events, photos, audio, or location.

What the app stores, and where

Everything below stays on your own device and in your own private iCloud database (Apple's CloudKit private database, tied to your Apple Account). It is readable only by you — and, if you choose, by someone you invite.

Data	Why	Where it goes
Sensor readings — pressure, sound level, motion	Detecting a door opening or the phone being moved	Processed live on the device; never stored or transmitted
Event log	Showing what happened while you were away	Device + your private iCloud
Alert photos	Showing who entered the room	Device + your private iCloud
Alert audio clips (10 s, optional)	Hearing what happened at the trigger	Device + your private iCloud; can be turned off
Device status — battery, armed state, heartbeat	Showing whether the sentry is alive	Your private iCloud
Hotel geofence (optional)	Arm reminders and automatic disarming	Your settings; never transmitted to anyone
Bluetooth proximity	Direct link when your devices are near each other	Encrypted, directly between your devices

Permissions

Microphone — sound detection while armed, and the optional 10-second alert clip.
Camera — a front-camera photo when an alert fires or you ask for one.
Motion & Fitness — barometer and accelerometer for detection.
Location (companion, optional) — the hotel geofence only.
Bluetooth — the direct link between your own devices.
Notifications — alerts, offline warnings and reminders.

Each permission is requested only when its feature is first used, and the app keeps working if you decline the optional ones.

Sharing with other people

You can share access to a sentry by showing someone a QR code. Scanning it lets their Apple Account read that sentry's events and send it commands. Anyone who obtains that code gains that access — treat it like a key.

Recording other people

Alert photos and audio clips may capture other people. Laws about recording people — especially audio — differ by country and region, and some places require notice or consent. You are responsible for using Hotel Sentry lawfully where you are. Audio clips can be switched off entirely on the Arm screen.

Retention and deletion

Data stays until you delete it. Deleting the app removes the local copy; deleting the app's iCloud data in Settings → your name → iCloud → Manage Account Storage removes the cloud copy. There is nowhere else for us to delete it from, because we never had it.

Children

Hotel Sentry is not directed at children and collects no data from anyone.
