Cipherly
Encrypt, disguise and hide messages — 100% offline
Cipherly locks messages and files with AES-256, disguises them as innocent emojis, or hides them inside a normal sentence with invisible ink. Paste anything and it auto-detects what it is. Notes live in a fingerprint-locked vault. Everything runs on your phone — no account, no cloud, no tracking. Works fully offline. Free.
Hey Product Hunt 👋
I build free tools at XniperBuilds, and the most-used one was a
little text encryptor. People kept asking for the same three things:
"can I use it offline", "can it not look encrypted", and "where do I
keep all these passwords?" — so I turned it into a proper Android app.
Cipherly does three jobs:
🔒 Lock — AES-256 encrypt any message or file with a password.
🙂 Disguise — the locked message can look like a harmless emoji
string, or hide inside a normal sentence (invisible ink).
🗄️ Keep — an encrypted vault for notes and passwords, opened with
your fingerprint.
The part I'm most proud of: paste ANYTHING into decode and it just
figures out what it is — cipher text, emojis, invisible ink, Morse,
binary. No menus.
Everything is on-device. No account, no server, no analytics. It
even works in airplane mode.
It's free — I'd genuinely love to hear what's missing or confusing.
Ask me anything, I'll be here all day.
@Muhammad Nazim good to know, plain base emoji is the right call then - way more durable. and the no-account thing is honestly the main reason I'd pick this over a normal notes app for anything sensitive, one less place for the data to leak from. nice work on this.
@muhammadnazim thanks for the detailed breakdown, that makes sense. one more thing on the emoji cipher specifically - since some platforms normalize or strip variation selectors and skin tone modifiers on emoji, does the cipher only rely on base emoji characters to stay safe, or does it lean on those modifier codepoints too and just accept that a handful of platforms might mangle it
how well does the invisible ink method hold up if someone just selects all and copies the text?
fully offline + fingerprint-locked vault is the right tradeoff for this category, most "secure notes" apps quietly want an account and a cloud sync which defeats half the point. the emoji/invisible-ink disguise is a fun touch too, curious if that's just steganography on the display layer or if the disguised output is actually safe to paste into places that strip unicode/formatting
