Privacy Policy
Last updated: 6 September 2026
1. Who We Are
LetProof is operated by QC Pro Apps Ltd ("we", "us"). Questions: support@qc-pro-apps.com.
2. Data We Collect
- Account data: email, name, password hash via Supabase Auth.
- Property & tenancy data: property addresses, tenant details, lease dates, compliance records you enter.
- Payment data: subscription billing handled by Stripe — we never see your card number.
- Usage data: page views, feature interactions (no advertising tracking). In the iOS app this is optional and off until you turn it on.
- Crash diagnostics (iOS app): if the app crashes or stops responding, we receive an anonymous diagnostic report — the type of fault, where in the app it happened, your iOS version and device model. It contains none of your documents, photos, property addresses or tenant details, and nothing that identifies you or your account. This is how we find and fix faults, so unlike usage analytics it is always sent.
- Cookies: essential session cookie + optional analytics. See our Cookie Policy.
3. How We Use Your Data
- To provide, maintain and improve LetProof.
- To process subscription payments via Stripe.
- To send compliance reminders and service notifications you request.
- To comply with legal obligations (UK GDPR / PECR).
4. Legal Basis
Contract performance (delivering the service), legitimate interests (security, fraud prevention, and diagnosing crashes so the app keeps working), legal obligation, and where required, consent. Optional usage analytics rely on your consent; anonymous crash diagnostics rely on our legitimate interest in a working product, which is why they are described rather than offered as a choice.
5. Data Sharing
- Supabase — authentication & database (EU servers).
- Stripe — payment processing.
- Google Firebase — Crashlytics receives the anonymous crash diagnostics described above; Firebase Analytics receives usage analytics only if you have turned them on in the iOS app.
- No data is sold or shared with advertisers.
6. Retention
Account data is kept while your subscription is active and for 12 months after cancellation, then deleted unless legally required to retain.
7. Your Rights
Access, rectify, erase, restrict, port or object to processing. Contact us at support@qc-pro-apps.com. You can also lodge a complaint with the ICO at ico.org.uk.
8. Security
TLS encryption in transit; data encrypted at rest. Access is role-controlled and logged.
9. Changes
We'll notify you by email of material changes. Continued use constitutes acceptance.
