Privacy Policy
Last updated: January 2025
Gridfinity Layout Tool is a free, open-source web application maintained by Andy Aragon. This policy explains what data we collect and how we use it.
Summary
- We collect anonymous analytics to improve the app (you can opt out)
- Layouts you create are stored locally in your browser unless you choose to share them
- When you share a layout, it's stored on our servers with a shareable link
- We don't sell your data or use it for advertising
Data We Collect
Analytics (Optional)
We use PostHog to understand how people use the app. This helps us prioritize features and fix bugs. Analytics data includes:
- Pages visited and features used
- Device type (mobile/tablet/desktop)
- Anonymous usage patterns (drawer sizes, bin counts)
- Errors and performance metrics
Analytics is optional. You can disable it in Settings > Privacy > "Help improve this tool."
When analytics is disabled, no data is sent to PostHog.
Layout Data
Local storage: Your layouts are stored in your browser's localStorage. This data never leaves your device unless you explicitly share a layout.
Shared layouts: When you create a shareable link, your layout data is uploaded to Vercel Blob Storage. Shared layouts include:
- Your drawer configuration (dimensions, grid settings)
- Bin positions, sizes, labels, and notes
- Categories and colors you've created
Shared layouts are accessible to anyone with the link. You can delete a shared layout at any time.
Real-time Collaboration
When you use the collaboration feature, your presence data (cursor position, anonymous display name) is shared with other participants via Liveblocks. This data is only transmitted while you're actively collaborating and is not stored permanently.
Data We Don't Collect
- Personal information (name, email, address)
- Payment information
- Precise location
- Cookies for advertising or tracking across sites
