Privacy Policy
Last updated: February 13, 2026The Short Version
Lugs is local-first. Your watch collection data lives on your device. There is no account, no signup, no email, and no login screen. We don't know who you are, we don't have your contact details, and we couldn't reach you even if we wanted to. Cloud sync is an optional Premium feature -- when enabled, your data is hosted in the EU.
Lugs ("we", "our", "the app") is a watch collection management app. We take your privacy seriously. This policy explains what data we collect, how we use it, and your rights.
1. Data We Collect
Data you provide:
- Watch collection information (brands, models, serial numbers, photos, purchase details, service records)
- Wear tracking data and accuracy measurements
- Wishlist items and market valuations
What we do NOT collect:
- Email addresses -- there is no signup or account creation
- Phone numbers
- Names or any personal identity information
- Location data
Data collected automatically:
- App usage analytics (screens viewed, features used) via PostHog -- only if you opt in
- Crash reports and error logs via Sentry -- to improve app stability
- Device type and OS version -- for compatibility
2. Data Storage
- Local storage: All watch data is stored locally on your device using SQLite. The app works fully offline. This is the default and only mode for free users.
- Cloud sync (optional, Premium only): If you enable cloud sync, data is synced to Supabase (hosted in the EU). Authentication is handled entirely through your existing Google account via the Play Store -- no separate login, no new credentials.
- Photos: Watch photos are stored on your device. If cloud sync is enabled, photos may be uploaded to secure cloud storage in the EU.
3. How We Use Your Data
- To provide and maintain the app's functionality
- To sync your collection across devices (if you opt in to Premium cloud sync)
- To generate insurance documents and export data at your request
- To improve app performance and fix bugs (via opt-in analytics and crash reports)
4. Data Sharing
We do not sell, rent, or share your personal data with third parties. Your watch collection is yours.
We use the following service providers:
- Supabase (EU) -- cloud sync (Premium, optional)
- PostHog (EU) -- anonymous analytics (opt-in only)
- Sentry -- crash reporting
5. Your Rights
Under GDPR and applicable data protection laws, you have the right to:
- Access your data -- export your full collection anytime (JSON/CSV)
- Delete your data -- delete all cloud-synced data from within the app
- Portability -- export and take your data with you
- Opt out of analytics at any time in Settings
Since there is no account, local data is entirely under your control. Uninstalling the app removes all local data. Cloud-synced data (if enabled) can be deleted from the app settings.
6. Data Retention
Local data remains on your device until you delete it or uninstall the app. Cloud-synced data (Premium only) is retained while sync is active. If you disable sync and request deletion, all cloud data is permanently removed within 30 days.
7. Children's Privacy
Lugs is not directed at children under 13. We do not knowingly collect data from children.
8. Changes to This Policy
We may update this policy from time to time. We will notify you of significant changes through the app.
