3. How We Use Your Data
We use your data exclusively to:
- Provide the service: Process receipt images, extract data via OCR, categorise expenses, and store records.
- Authenticate you: Verify your identity via Auth0 to protect your account.
- Isolate your data: Ensure you only see your own receipts, projects, and budgets.
- Generate reports: Produce CSV exports and summaries for tax returns or household tracking.
- Improve the service: Analyse anonymised usage patterns to improve features (no personal data shared).
We do not:
- Sell your personal data to third parties.
- Use your data for advertising.
- Share your receipt images or financial data with anyone.
4. Data Processing and Sub-Processors
We use the following sub-processors to deliver our service:
| Sub-Processor | Purpose | Data Processed | Location |
|---|---|---|---|
| Microsoft Azure | Cloud hosting, storage, database | All service data | UK South (London) |
| Azure Document Intelligence | OCR receipt scanning | Receipt images (processed in-memory, not retained) | UK South |
| Azure OpenAI | AI categorisation fallback | Receipt text (processed in-memory, not retained) | UK South |
| Auth0 (Okta) | Authentication | Email, name, login credentials | EU (UK region) |
All sub-processors are bound by data processing agreements. Azure services are configured in the UK South region to maintain UK data residency.
5. Data Storage and Security
5.1 Storage
- Receipt images: Azure Blob Storage (UK South), encrypted at rest (AES-256), access controlled by user ID prefix.
- Receipt data: Azure Cosmos DB (UK South), encrypted at rest, partitioned by user for data isolation.
- Authentication tokens: Stored in browser memory only (not persisted to disk).
5.2 Security Measures
- All data transmitted over TLS 1.2+.
- Authentication via Auth0 with JWT tokens (RS256 signed).
- Managed Identity for service-to-service authentication (no API keys in code).
- All database queries filtered by authenticated user ID.
- Passkey support (FIDO2) for phishing-resistant authentication.
6. Data Retention
| Data Type | Retention Period | Justification |
|---|---|---|
| Receipt data and images | Until you delete them, or account closure + 30 days | HMRC requires 5-year record keeping; we leave retention to you |

| Application logs | 30 days | Debugging and operational support |
| Authentication logs | 90 days (Auth0) | Security monitoring |
You can delete individual receipts at any time via the app. Deleted data is permanently removed from our database and blob storage.
