Privacy Policy

Last updated: September 2026

1. Data Controller

WarrantyWallet is operated by Gulbrandsen Apps, a sole proprietorship (enkeltpersonforetak) registered in Norway (org. no. 938 324 484). For privacy inquiries, contact privacy@warrantywallet.dev.

2. Information We Collect

Account data: Email address, display name, and encrypted password when you register.

Warranty data: Product names, purchase dates, expiration dates, store names, prices, descriptions, and categories that you enter.

Documents: Receipt images and documents you upload, along with OCR-extracted text.

Usage data: Basic analytics such as app opens and feature usage to improve the service.

3. Lawful Basis for Processing (GDPR)

We process your personal data on the following legal bases:

• Contract performance — processing necessary to provide the WarrantyWallet service you signed up for (account management, warranty storage, OCR, notifications).
• Legitimate interest — basic analytics to maintain and improve service reliability and security.
• Consent — optional features such as household sharing and push notifications, which you can enable or disable at any time.

4. How We Use Your Data

We use your data to provide and improve the WarrantyWallet service, including: storing your warranties, processing documents with OCR, sending expiration reminders, and enabling household sharing.

5. Data Storage & Transfers

Your account data, warranties and receipt images are stored on Microsoft Azure servers in Europe (West Europe region), with documents held in Azure Blob Storage behind encrypted access tokens. When you scan a receipt, the image is sent to our AI OCR provider (Anthropic) for processing in the United States; aside from that OCR step, your data is kept within the EU/EEA.

6. Third-Party Services

We use the following third-party services to operate:

• Anthropic (Claude) — AI-based OCR that reads your scanned receipts to extract their details (processed in the United States; not used to train AI models)
• Azure AI Document Intelligence — fallback OCR provider, used only when the AI service is unavailable
• Azure Blob Storage — for secure document storage

These providers process your data only on our behalf to deliver the service. We do not sell your data to third parties.

7. Household Sharing

When you share warranties with household members, those members can see the shared warranty details and any associated documents. Only warranties you explicitly mark as shared are visible to household members.

8. Data Retention

Your data is retained as long as your account is active. When you delete your account, all your data (warranties, receipts, documents, and account information) is permanently deleted within 30 days.

9. Your Rights

Under the GDPR, you have the right to:

• Access — request a copy of all personal data we hold about you
• Rectification — correct your personal information at any time
• Erasure — delete your account and all associated data
• Data portability — receive your data in a structured, machine-readable format
• Restriction — request we limit how we process your data
• Objection — object to processing based on legitimate interest
• Withdraw consent — where processing is based on consent, withdraw it at any time

To exercise any of these rights, contact privacy@warrantywallet.dev. We will respond within 30 days.

You also have the right to lodge a complaint with the Norwegian Data Protection Authority (Datatilsynet) at datatilsynet.no.

10. Security

We use industry-standard security measures including encrypted connections (HTTPS), hashed passwords (BCrypt), and time-limited access tokens for document storage.

11. Children

WarrantyWallet is not intended for users under the age of 13. We do not knowingly collect data from children.

12. Changes

We may update this privacy policy. We will notify you of significant changes through the app.
