Zero-knowledge file/paste/poll/chat sharing for anyone who canโt trust Drive/Slack/WhatsApp with sensitive stuff. Client-side AES-256-GCM; keys live in the URL fragment (server never sees content or metadata); no accounts/PII/phone numbers. Runs on Cloudflare Workers with region pinning. Pricing: pay-per-use credits (per GB uploads, per secure paste/chat/poll), bulk credit packs for frequent users. Target: lawyers/healthcare/M&A contractors/agency folks needing one-off or short-lived private exchanges; supports group chat but no team workspace. Moat: true zero-knowledge (only encrypted blobs to subpoenas), compliance-friendly regions, link-based flows with no signup

Privsen's answer:
Zero-knowledge by default: client-side AES-256-GCM, keys in the URL fragment, no accounts/PII/phone numbers, no metadata logging. We literally cannot decrypt your content or comply with data requests beyond handing over encrypted blobs.
Privsen's answer:
If you need to share up to 15GB files, notes, polls, or chats without trusting a provider, Privsen keeps keys client-side and doesnโt require identity. No server-stored keys, no hidden backups, no data monetizationโjust pay-per-use credits.
Privsen's answer:
People and teams handling sensitive exchanges without wanting Drive/Slack/WhatsApp involved: lawyers, healthcare contractors, M&A/agency folks, security-minded individuals needing short-lived, private links.
Privsen's answer:
We built Privsen after seeing โencryptedโ services still log metadata, store keys, and wipe accounts via bots. We wanted a tool that is blind by design: keys stay with the user; providers canโt read, track, or sell data.
Privsen's answer:
Next.js, React, TypeScript, Hono, R2, KV, D1 Web Crypto API (AES-256-GCM, HKDF).
Privsen's answer:
Early-stage; privacy-focused professionals and small teams using pay-per-use credits.
