Privacy Policy
Last Updated: July 2026
1. The Client-Side Guarantee
PaperTrail is designed around a thick-client, browser-first architecture. When you upload or drag spreadsheets (.xlsx, .xls, .csv, .tsv) into this application, all data parsing, format type checks, alignment logic, and print previews are performed entirely on your own computer using client-side JavaScript.
2. What We Collect
Because this is a business formatting tool, we only collect minimal, non-identifiable usage statistics to evaluate utility and performance. The parameters captured are:
- Usage Telemetry: An anonymous counter logs when a file is dropped (upload event), parsed (process event), or downloaded/saved (print event) along with row and column limits (e.g. "processed a sheet with 150 rows and 8 columns").
- Network & Diagnostic Metadata: We track visitor IP addresses and User Agent details for system health auditing, server performance tuning, and security purposes.
3. Local Storage Usage
We do not store cookies on your machine. Instead, we use the browser's native localStorage API to save layout presets, visual theme preferences, table grid styles, and company letterhead input fields. This information remains local to your device and is never sent to our database.
4. Contact Information
If you have questions about our client-side architecture or privacy implementations, contact us directly.
