Vim Python IDE
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
Early-stage; privacy-focused professionals and small teams using pay-per-use credits.
