Safe by design.
Encrypted and anonymous.

Everything you save is encrypted on your device with a key made from your 16-digit number. No email, no account, no name attached — just your stash, and only you can open it.

Three things that keep your stash yours

🔒

Encrypted on your device

Your notes, pages, and snippets are scrambled in your browser before they ever sync. What we store is unreadable code — useless without your key.

🔑

Only your key opens it

Your 16-digit number is the key. It's never sent to us and never stored on our servers, so you're the only one who can unlock your stash.

👤

Truly anonymous

No email, no name, no account. There's nothing tying your stash to you — even we don't know whose it is or what's inside.

🛡️

Safe even if we're breached

If our servers were ever stolen, an attacker would get scrambled data with no names attached — nothing readable, nothing to trace back to you.

Keep your number safe

Because only your number can open your stash, nobody can recover it for you if you lose it — not even us. There's no reset email. Save your number somewhere safe, and use Export in the app (⚙️ → Export) to download a backup copy anytime.

FAQ

No. Your stash is locked with a key that only lives on your device. It's not a policy we promise — it's how the app is built. Without your number, your notes are unreadable to us or anyone else.

Your text — notes, pages, snippets, logs — is encrypted with your personal key today. Uploaded files are stored encrypted on our side, with per-file encryption tied to your key rolling out next. Until then, keep your most sensitive material as text.

No — and that's the point. If we could recover your stash without your number, so could an attacker. Save your number somewhere safe, and keep an Export backup as your safety net.

Just type your number. Your key is rebuilt from it on the spot, on any device — nothing to transfer, nothing to set up.

Quickstash is local-first: your stash is decrypted and kept in that browser so it opens instantly and works offline. That copy stays on the machine after you log out, which is what makes the app fast on your own device — and what you need to think about on a shared one.

On a computer you share, use Logout & erase instead of plain Logout. It syncs anything pending, then wipes every note, page, log and cached file from that browser. Nothing is lost — your stash lives on encrypted in the cloud, and signing back in with your number restores it.

If you skip the erase and someone else signs in with their own number on that browser, the leftover local notes are treated as unsynced work and merged into their stash. Same mechanism that lets you merge your own stashes together — so on shared machines, always erase.

Safe, private, and yours.
