Security & Data Privacy Invariants
Your documents, research papers, and text inputs belong exclusively to you. Here is how we enforce strict security invariants.
🔒 Client-Side & Browser-First Execution
Many tools—including our PDF Editor and Word Counter—execute client-side JavaScript inside your browser sandbox. For operations that do not require server compute, your documents never leave your local device.
⏱️ Automatic Ephemeral File Deletion
When files are uploaded for backend conversion or OCR parsing, they are stored in a sandboxed ephemeral directory and purged automatically upon completion or within 1 hour via background cleanup daemons.
🚫 Zero Data Harvesting & No AI Training
We do not sell, log, or use your uploaded papers, essays, or text inputs to train public AI models. Your content remains completely confidential.
🔐 Transport Encryption (TLS 1.3 & HSTS)
All network communications between your browser and Cluster AI are encrypted with TLS 1.3 protocol and protected with HTTP Strict Transport Security headers.
