Welcome to Lamin Property Manager (“we”, “our”, or “us”). We are committed to protecting your privacy. This Privacy Policy outlines how your data is handled when you use our mobile application.
1. Local-First Architecture
Lamin operates on a local-first model. All property records, expense numbers, bills, tenant agreements, ownership splits, and notes are stored locally on your device in an encrypted SQLite database. We do not operate central servers that track, collect, or sell your personal or financial data.
2. Cloud Backup & Sync (Optional)
Lamin offers an optional Cloud Backup & Sync feature to allow users to back up their data and access it across multiple devices:
Direct to Your Private Cloud: When enabled, backup snapshots are uploaded directly to your own private Google Drive or Apple iCloud account.
No Developer Access: We have no access to your cloud storage credentials, account files, or database backups.
Limited Scope: When signing in with Google, the app requests strictly scoped access (drive.file / drive.appdata) to create and update only Lamin’s own backup files. It cannot read, access, or modify any other files in your Google Drive.
3. In-App Purchases & Subscriptions
Purchases and auto-renewing subscriptions (Lamin Pro) are processed securely by Apple via StoreKit.
We use RevenueCat as a subscription management service to validate receipts and manage active entitlements. RevenueCat receives an anonymous app user identifier and receipt tokens. No payment or credit card details are ever shared with or stored by us.
4. Diagnostics & Crash Reporting
We use Sentry to collect anonymized crash reports and app performance metrics. This data helps us diagnose bugs and improve application stability, and contains no personally identifiable financial information.
5. Camera & File Storage Permissions
Camera / Photo Library: Used solely when you choose to photograph paper receipts or attach bill images.
Documents: Used solely when you attach PDF invoices or import/export backup files.
6. Data Deletion
Because your data is stored on your device and in your personal cloud storage:
You can delete all local data at any time via Settings > Clear All Data.
You can delete your cloud backups directly within the app or from your Google Drive / iCloud storage.
Uninstalling the app permanently removes all local records and cached receipts from your device.
