Effectve date: 2025-10-09 

Who we are:
Delaquis Prompt Engineering (PTY)Ltd. 

Contact: apps@dpe.li 

What the app does :
The app pairs with a Plegium® Smart Button (via Bluetooth) to trigger an SOS alarm. When the user presses the button or taps the in-app control, the app sends an SMS to the user’s chosen contacts and can optionally initiate a phone call and include the user’s location in the message.

Data we process:     
Contacts selected by the user (phone numbers only): stored locally on the device for sending alerts. We do not upload or share them with our servers.
Location (approx./precise): used only when the user enables location in alerts to include the current location in the SMS. Location is not stored or sent to us.
Bluetooth: used to maintain a connection with the Smart Button and detect button presses.
Diagnostics (crash logs, device data): none by default; we do not include third-party analytics or ads.

Permissions and purpose: 
SEND_SMS – send the user-defined alert SMS to selected contacts.
CALL_PHONE – optionally start a phone call to a selected contact when enabled.
ACCESS_FINE_LOCATION/ACCESS_COARSE_LOCATION – include location in the alert message if enabled by the user.
BLUETOOTH/BLUETOOTH_CONNECT – connect to the Plegium® Smart Button.
FOREGROUND_SERVICE – keep the Bluetooth connection reliable while the app runs.
POST_NOTIFICATIONS (Android 13+) – show service and status notifications.

How we use and share data
We do not operate backend servers for this app. Personal data (contacts, location) is used on-device to send SMS/calls that you initiate. We do not sell or share personal data with third parties.
SMS are sent through the user’s mobile network provider; standard carrier charges apply.

Retention:
 Contact numbers and settings remain on the device until you edit them or uninstall the app. We do not retain copies on our servers.

User choices & controls
All permissions are optional and requested at runtime. You can disable them in system settings.
You can remove contacts or turn off location in alerts at any time in the app settings.
To delete all app data, uninstall the app. We hold no server-side data to delete.

Children 
The app is intended for adults (18+) and is not directed to children. 

Security:
Data in transit (e.g., Bluetooth pairing, optional network requests) is protected using industry-standard encryption where applicable. SMS are transmitted via the mobile network and may not be end-to-end encrypted.

Changes 
We may update this policy from time to time; changes are posted on this page with the effective date.
