Technical Architecture & Threat Model
Scrolling down through hundreds of transaction records causes confusion once column labels disappear off the top edge of your screen. Foxcolab Sheets lets you freeze up to five top header rows and five left columns. As you scroll deep into your data grid, headers stay permanently pinned in place so you always know what each column represents.
Spreadsheets contain a business's most confidential trade secrets: customer lists, financial valuation models, profit margins, and payroll projections. Mainstream cloud spreadsheet providers routinely process this raw tabular data on remote servers where it remains exposed to automated indexing and administrative inspection. Foxcolab Sheets was engineered to deliver the calculating power and real-time collaboration of modern web spreadsheets while keeping your financial models cryptographically protected on your own devices.
Zero Content Leakage Boundary
Under Foxcolab security architecture, administrative visibility never equals content visibility. No messages, documents, spreadsheets, recordings, or intake answers are ever logged, analyzed for advertising, or accessible to infrastructure operators. Keys remain strictly isolated on authorized endpoints.
