AgePony: age Encryption

Here's the full ASO-tuned long description — keyword-front-loaded opening (the part shown above "read more"), file-type expansion, and natural keyword density. Accurate to what the app actually does, and well under Play's 4000-character limit.

AgePony is a private, offline file encryption app built on age — the simple, modern encryption standard trusted by developers and security-minded people everywhere. Encrypt files, text, and notes right on your device. No account, no cloud, no tracking.
Lock down a document before you send it, paste an encrypted block into a chat or email, or keep private notes that only your passphrase can open. AgePony does it all with real age encryption, so anything you encrypt here can be decrypted with the age command-line tool or any compatible app — and anything encrypted elsewhere with age opens right here.
WHAT YOU CAN DO

Encrypt and decrypt files — documents, photos, PDFs, archives, or any file type — and save the result wherever you like.
Encrypt and decrypt text, with clean ASCII-armored output that's safe to paste into email, chat, or a forum post.
Keep encrypted notes, each protected by its own passphrase.
Generate your own age identity (X25519) and share your public key so others can encrypt files to you.
Add recipients by pasting an age or SSH public key, fetching someone's public keys from their GitHub username, or scanning a QR code.
Encrypt to SSH keys too (ed25519 and RSA) — useful if you already manage keys for servers or Git.
Protect with a passphrase instead of a key when that's simpler, using scrypt at the age standard work factor.

A SIMPLE PGP / GPG ALTERNATIVE
If PGP and GPG always felt heavy, age is the answer — a small, auditable, well-documented format with no complicated key-management ceremony. AgePony gives you a friendly front end for encrypting files and messages without hiding what's actually happening underneath. Same standard, fully interoperable, just easier to use on the go.
BUILT FOR PRIVACY

Your master key is wrapped by the Android Keystore and can be gated behind your fingerprint, face, or device credential.
Your vault — identities, saved recipients, and encrypted notes — is stored encrypted on your device.
AgePony works offline. The only time it touches the network is the optional GitHub key lookup, and only when you ask for it.
No sign-up, no analytics, no ads, and no servers holding your data.

WHY AGEPONY
Strong encryption shouldn't require a desktop, a manual, or a degree in cryptography. AgePony brings standard age encryption to your phone in a clean, fast, no-nonsense app — whether you're protecting a single file, sending an encrypted message, or keeping a few private notes locked down.
AgePony is completely free.
