● how it works
Pick a @username in 6 seconds. No email, no phone, no photo. Just a passphrase only you hold.
Stick bindu.app/you in your bio, story, or AirDrop it across the lunchroom.
Crushes, confessions, callouts, compliments. Decrypted in your browser. We never see plaintext.
Post the best ones to your story with one tap. Mute the rest forever by hash.
● features
Not another social network. A dot-sized inbox that lives in your bio and stays out of your way.
● privacy by design
Most "anonymous" apps know exactly who you are. We don't, because we can't. Here's the math.
Read the security paper →Messages are encrypted in your browser with ECDH+AES-GCM before they leave. Our servers see ciphertext only. Decryption happens in your browser, with a key only you hold.
Block a sender? We block their hash — we never knew who they were. Not even law enforcement can compel what we don't have.
We strip device IDs and don't log IP addresses with messages. Senders are un-linkable to messages after delivery.
Slur detection, self-harm flags, and doxxing filters run in your browser — no message content is sent to our servers for moderation. Ever.
● questions, honestly
Yes — we use end-to-end encryption (ECDH P-256 + AES-256-GCM via the browser's WebCrypto API), don't log sender IPs with messages, and only store hashed sender IDs. Even we can't tell who sent what. We've published our full security architecture for independent audit.
