Macarius Retail POS privacy notice
Updated 3 November 2026
Macarius supplies Macarius Retail POS. Contact sales@macarius.co.uk or +44 1615661760, or write to 34 Blandford Street, Ashton-under-Lyne, OL6 7DW, United Kingdom, with questions about this notice or your information.
Shop registration and licensing
When you register a shop, the app sends the shop details you enter and its installation/device identifier to the Macarius licensing service at pos.macarius.co.uk. Registration may include your name, shop name, address, telephone number, email address, website and logo. The service uses registration and device information to associate the installation with your shop, manage a trial or paid licence, and let Macarius approve or renew access remotely. Licensing checks require an internet connection. Registration is not an instruction to subscribe you to marketing email.
Mobile administrator access and shared shop records
The Macarius iOS and Android companion apps use the same administrator account and business access as the enrolled Windows till. To provide mobile access, the Windows till sends business records to the Macarius service at pos.macarius.co.uk over HTTPS. These records include products, stock, sales and sold product lines, staff, customers, suppliers, purchases and saved quotes. Records may contain staff and customer information entered by the shop. Mobile access is limited to the administrator's authorised business.
Product creation, stock adjustments and quotes submitted from mobile are stored as requests for the enrolled Windows till. The till applies requests when it is available and safe to do so, then returns their status and updated records. The service retains request and completion information to prevent duplicate changes and support auditing. A queued request is not confirmation that the Windows records have changed.
The service stores password verification hashes, account and business membership details, and sign-in session information. If you register a passkey, it stores the public credential needed to verify sign-in; the private passkey remains with your device or passkey provider. Device sign-in codes are short-lived and require approval. The mobile app uses platform-protected credential storage for its sign-in token.
Camera access is used for on-device product-barcode and device-sign-in scanning. The mobile scanner does not send camera images to Macarius. Product barcodes you enter when creating records are included in those business records. Contact Macarius using the details in this notice to request information about access, correction, retention or deletion of the account and shared records. The shop remains responsible for the customer and staff information it records.
Local shop records
Sales, stock, categories, quotes, shop settings, staff accounts and configured business integrations are processed on the shop's Windows computer. Records can contain information entered by the shop about staff or customers. The shop decides what to enter and how long to keep its business records. The app uses Windows credential encryption for supported stored credentials and licensing files; this does not mean every local business record is encrypted.
The Microsoft Store edition keeps its working profile and business files under the signed-in Windows user's Macarius POS Data\Retail folder. Migration from a previous installation copies available shop data and leaves the original files in place. Uninstalling the Store app retains this folder so the shop can recover its records. Keep backups and control access to the Windows account and computer. Contact support before removing data needed for your records.
Optional services
Connecting Shopify, a payment terminal, the owner dashboard or another optional integration sends the information needed for that chosen operation to the configured service. Payment processing is handled by the chosen payment provider. Product-photo lookups send a product barcode to Open Food Facts and retrieve available photos from its image service. Printing sends selected receipt or document content to the chosen printer. Windows and Microsoft Store handle app distribution and updates under Microsoft's own notices.
Email delivery is not required to use the local till. If Macarius enables the optional shop notification service, explicitly sending a report or quote can send the selected document and registered recipient address to Macarius for delivery. Ask support about service availability before relying on automatic notifications.
Your requests and retention
Contact Macarius to request access to, correction of, or deletion of shop registration and licensing information held by Macarius, or to ask about its retention. Requests may require confirmation that you control the shop account. For staff or customer information recorded by a shop, contact that shop first. Some information may need to be retained to provide an active licence, resolve a support request or meet applicable obligations; support can explain the information relevant to your request. Do not send passwords or full payment-card details to support.
This notice will be updated when the app's data practices change. The published version and date should be reviewed before using a newly enabled optional service.
