Privacy policy

Last updated 29 September 2026

Who we are

Smart Sentry makes a home alarm system: a hub, wireless motion sensors, a remote and this app. Smart Sentry is made by Future Technology, the developer named on our app store listing. This policy explains what information the system uses, why it needs it, and the choices you have. It covers the app, the hub and sensors, and our website.

What we collect

• Your account: your email address and a password. Passwords are checked by our sign-in service and are never visible to us.
• Your system: the hub ID, the names you give your hub, home and sensors, your settings (arming countdown, schedule, holiday dates, siren time limit) and the people you share access with (their email address and what they are allowed to do).
• Alerts: what happened (for example movement while armed, a panic alarm or a sensor that stopped responding), which sensor, and when.
• Hub health: whether the hub is online, when it last checked in, its software version and why it last restarted.
• This phone: a notification address so alarms reach this phone. The phone's make is read on the phone only, to show the right setup steps.
• Order requests: when you ask for a kit on our website, your name, email address, phone number if you give it, your town or suburb, how many sensors you want and your note, so we can contact you about it.

What we do not collect

• The sensors detect movement only. They do not record video, pictures or sound.
• The detailed arming and disarming history stays on the hub in your home. Our servers keep only the current state so the app can show it.
• No advertising, no usage tracking, and we do not track where your phone is.
• If you installed the Android app from our website, it checks there for a newer version (at most once a day, or when you ask it to). It downloads a public file and sends no account or phone information. The app from an app store is updated by the store instead.

How we use it

• To send alarms and notices to you and the people you share with.
• To let you arm, disarm and change settings from the app.
• To keep the system secure and working, and to fix problems you report.

We do not sell your information and do not use it for advertising.

Where it is kept and who can see it

Your information is stored with trusted cloud service companies that run our servers and deliver notifications to phones. They may only use it to provide that service to us. Our servers are mainly in South Africa and the European Union; alarms reach your phone through the notification service built into your phone's operating system.

Only you and the people you share access with can see your system and its alerts. We look at your information only when you ask us for help or to keep the service secure, and we share it with authorities only when the law requires us to.

Security

Every hub has its own secret keys, and the hub checks every command from the app before it acts on it. Connections between your hub, our servers and the app are encrypted. If your internet goes down, the hub, sensors and remote keep protecting your home. No system is perfectly secure, so we keep improving and ask you to use a strong, unique password.

How long we keep it

• Alerts are deleted automatically after 90 days, and clearing the alert list hides them from your account straight away.
• Your account and system settings stay until you remove them. Removing a hub in the app deletes its alert history and resets the hub.
• Handing your hub over to a new owner deletes its alert history, so they never see yours. They see your email address with the offer.
• When you delete your account in the app, it is deleted straight away with everything kept with it: hubs you own are removed and reset, and you leave hubs shared with you. If you ask us by email instead, we do the same within 30 days. Security logs that show how the service was used may be kept for up to 30 days, unless the law requires us to keep something for longer.
• Order requests are kept while we handle your order. If you buy, the order is kept for as long as tax law requires. To stop misuse of the order form, a scrambled form of your internet address is kept for up to two days.

Your choices

• Choose which alerts reach your phone in Settings.
• See and remove the people who can use your hub in its settings.
• Delete your account and its information at any time in the app (Settings, then Delete account) or on our website at https://smartsentry.co.za/delete-account. You can also ask us by email.
• Ask us for a copy of your information, or to correct it, by email.

Children

Smart Sentry accounts are for adults. We do not knowingly collect information from children.

Changes to this policy

If we change this policy, we update the date at the top. For important changes we will also tell you in the app before they take effect.
