Merges, signs, protects, and flattens sensitive client contracts and deliverables entirely in-browser without server upload.
💼 Curated No-Login Stack Productivity & Privacy Freelancers, Contractors & Independent Consultants
Confidential Client Workflow Stack
Professional contracts, encrypted file delivery, and private communication without account footprints
"Deliver world-class client work while keeping non-disclosure agreements and confidential drafts strictly secure."
Independent consultants and freelancers handle highly sensitive client documents—trade secrets, financial statements, and early product roadmaps—under strict non-disclosure obligations. Routing these client assets through invasive third-party SaaS creates legal vulnerability and tracking exposure. This stack equips you with an air-tight, zero-account operational foundation: compile and sign PDF agreements locally, transmit multi-gigabyte deliverables over peer-to-peer encrypted channels, and share sensitive credentials via auto-destructing secret links.

Stack Architecture & Privacy FAQs
How does client-side PDF signing comply with confidentiality agreements?
Because tools like PDF24 execute signature rendering in the local browser canvas without dispatching the document bytes to remote servers, the file never leaves your physical perimeter—satisfying strict enterprise NDAs.
What happens to files sent via Wormhole once downloaded?
Wormhole keys are held only in the link URL fragment (#). Once the link reaches its configured expiration or download threshold, the ciphertext is permanently purged from relays.
