Effective date: 20 April 2026
Supermarkit ("we", "our", "the app") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
1. What we collect
Account information
When you create an account, we collect your email address and display name. If you sign in with Apple, we receive the information you choose to share (which may include a private relay email).
Receipt data
When you scan a receipt, the app extracts item names, prices, store names, and totals. This data is stored in your personal account to power your spending insights, price tracking, and budgets.
Household data
If you join or create a household, your receipt data and shopping lists are shared with other members of that household. You can leave a household at any time from Settings.
Usage data
We collect basic analytics about how you use the app (screens viewed, features used) to improve the product. This data is anonymised and cannot be used to identify you personally.
2. How we process your data
On-device scanning
Receipt text is first extracted on your device using Apple's Vision framework. No images of your receipts are sent to our servers.
AI-enhanced parsing
To improve accuracy, the extracted text (not the image) may be sent to our secure cloud service for processing by an AI model. This text is used solely to parse your receipt and is not stored after processing is complete.
Data storage
Your account and receipt data is stored securely using Google Firebase, hosted in the EU. Data is encrypted in transit and at rest.
3. What we do NOT do
- We do not sell your personal data to third parties
- We do not share your receipt data with advertisers
- We do not use your data for targeted advertising
- We do not store images of your receipts on our servers
- We do not share your data outside your household without consent
4. Third-party services
We use the following third-party services to operate the app:
- Firebase (Google) — authentication, database, and cloud functions
- RevenueCat — subscription management (if you subscribe to a paid plan)
- Anthropic (Claude) — AI-powered receipt parsing
Each of these services has their own privacy policy and processes data in accordance with their terms.
5. Your rights
Under UK GDPR, you have the right to:
- Access your data — see what we hold about you
- Correct inaccurate data
- Delete your account and all associated data (available in Settings → Delete Account)
- Export your data in a portable format
- Object to processing of your data
To exercise any of these rights, email us at privacy@supermarkit.com.
6. Children's privacy
Supermarkit is designed for families and is rated 4+. We do not knowingly collect personal information from children under 13 without parental consent. The app is intended to be used by parents and guardians to track household spending.
7. Data retention
We retain your account and receipt data for as long as your account is active. If you delete your account, all associated data is permanently removed within 30 days.
8. Changes to this policy
We may update this privacy policy from time to time. If we make significant changes, we will notify you through the app. The "effective date" at the top of this page indicates when the policy was last updated.
