What it does
Privsen is a privacy-first toolkit where encryption happens in your browser before anything touches our servers. We literally cannot see your uploads. Share encrypted files up to 15GB, send self-destructing secrets, create anonymous polls, or launch encrypted chat rooms - all without creating an account. The decryption key lives in the URL fragment and never hits our servers. Built for people tired of "trusting" cloud services with their data. Free for most use cases. No email required.
Share files securely with zero-knowledge encryption. Up to 15GB encrypted file sharing, anonymous polls, encrypted pastebin, self-destructing messages. Your files, your control – we can't access them even if we wanted to.
We don't just say we're private. We prove it. Our encryption is strictly client-side ( AES-256-GCM ), so your data is locked before it ever leaves your device. Our infrastructure is zero-knowledge by design. Expert guides on staying safe online. Learn about encryption, data breaches, secure communication, and how to protect yourself fromfrom privsen.com
In the maker’s words, at launch
It is brand new, still early, and I’m curious what questions comes to mind after you take a look at it.

Burner NoteJan 2026 · burnernote.com · ▲222In 2021 after getting thoroughly sick of Privnote, i built "Burner Note". Even though i didn't promote it in anyway other than a post here and a post on reddit, it ended up getting about 7000(ish) unique users per month. I kinda let it die about 18 months ago but i've resurrected it with some big upgrades. Most botable the app is now truly end to end encrypted (previously was just server side), and I've added dark mode as well as a few other bells and whistles. Feedback welcomed.
- FSFlashpaper – Self-destructing secret sharing with no databaseJul 2026 · flashpaper.app · ▲25
Hi everyone! This is my first HN and I’m very new to the scene. My name is Min from Bangkok. At first, I just want to create a dead man's switch for personal use and for fun. then, I think about information that self destruct like a spy movie. after that, I try to come up with the better version of Privnote or Bitwarden with self-destruct and some kind of censoring or blocking download ability. Somehow, end up with this product. :O Flashpaper is for sending any information that would be burned after reading (with counting down timer like Mission Impossible movie ! or after 24 hrs max if not…
SecretDropFeb 2026 · secretdrop.dev · ▲8Hey everyone, English is not my native language. This post was polished with AI, but the content is mine. I run a small dev agency in Germany. Every week someone shares database credentials, API keys, or a .env file via Slack or email. Not because they don’t care: because there’s no frictionless alternative. Vault setups are heavy. Enterprise tools are expensive. I just needed: upload → share link → done. But encrypted before leaving the browser. So I built SecretDrop.dev. What it does Files encrypted client-side (AES-256-GCM, PBKDF2 600k iterations) Built entirely on WebCrypto No…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
