Questions & Answers

As answered by people managing FullStackToolkit and Privsen.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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 doesn’t require identity. No server-stored keys, no hidden backups, no data monetization—just pay-per-use credits.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

Privsen's answer:

We built Privsen after seeing “encrypted” 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 can’t read, track, or sell data.

Which are the primary technologies used for building your product?

Privsen's answer:

Next.js, React, TypeScript, Hono, R2, KV, D1 Web Crypto API (AES-256-GCM, HKDF).

Who are some of the biggest customers of your product?

Privsen's answer:

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