Privacy Policy & Terms of Service

🔒 Your Files & Data

• No File Uploads: All file conversion happens locally in your browser using WebAssembly and JavaScript (FFmpeg/document libraries with custom logic)
• Zero File Storage: Your files never leave your device and are not transmitted to any servers
• No Personal Data Collection: We don't collect names, emails, or any personal information
• Browser-Only Processing: Conversion libraries are downloaded and cached locally for offline use

📊 Anonymous Data Collection

To improve the service and monitor for issues, we collect limited anonymous data when privacy mode is disabled:

🛡️ Your Control

You have complete control over data collection. Both consents are on by default and each can be turned off independently at any time:

• Two settings toggles: Open Settings (⚙️) → App for separate "Anonymous usage analytics" and "Automatic error reports" switches
• Anonymous usage analytics: A single cookieless page view so we can gauge aggregate traffic - no account, profile, or cross-site tracking
• Automatic error reports: When a conversion breaks, the error plus the file extension and quality/size settings are sent. Filenames and personal data are never collected (and stripped if present); your files and their contents never leave your device
• Welcome opt-out: On your first visit, the welcome card lets you opt out of both at once
• Report issue button: When a conversion fails you can send that one error on demand, even with automatic reporting off
• Manual reports always work: Bug reports you choose to send still reach us regardless of the toggles above, so we can help
• Persistent: Your choices are saved locally and remembered across visits

🌐 Third-Party Services

• CDN Loading: Conversion libraries (FFmpeg WebAssembly) are loaded from CDNs on first use
• Offline Capability: After initial load, the app works completely offline
• No External Tracking: We don't use Google Analytics, Facebook Pixel, or other third-party trackers

📍 Data Location

• Analytics: Processed on our self-hosted Umami instance
• Error Tracking: Stored on our self-hosted Bugsink instance (Sentry-compatible)
• Geographic Location: Servers hosted in data centers with appropriate security measures
• Retention: Analytics and error data is retained for service improvement and is periodically cleaned
