This Data Processing Agreement and Data Access Appendix governs personal data processing and commercial/operational data access when a Restaurant, Supplier or other business user connects to Qastio, enables POS/API integration, uses analytics, participates in procurement, uses the voluntary payment module or gives Platform users dashboard access.
2. Roles
Processing activity | Typical role of Operator | Typical role of Restaurant / Supplier |
|---|---|---|
Guest order routing | Processor or independent controller depending on implementation | Restaurant is usually controller for fulfilment and customer relationship. |
Restaurant dashboard accounts | Controller for Platform account/security; processor for Restaurant staff data where instructed | Restaurant controls staff authorisations and account users. |
POS/API integration | Processor or joint/independent controller depending on purpose | Restaurant confirms lawful right to provide POS/API data. |
Aggregated procurement analytics | Independent controller for aggregated/anonymised commercial analytics | Restaurant provides business data under contractual access rights. |
Supplier procurement offers | Independent controller for supplier account and procurement coordination | Supplier controls product documents and supply data. |
Voluntary payment module | Controller for Platform logs/status; PSP is separate controller/processor under its terms | Restaurant remains seller/merchant where applicable; PSP processes payment data. |

- Use subprocessors only with required notice or authorisation where applicable.

4. Data Access Matrix
Data category | Sensitivity | Permitted purpose | Disclosure |
|---|---|---|---|
Public Restaurant data | Low | Restaurant profile, QR menu, opening hours, menu display and promotion. | Displayed publicly. |

5. Security Measures
- Role-based access controls and account permissions.
