Ding Dong: Soft Encrypt

RED MUTEX LIMITED

About this app

Ding Dong is a free, friendly soft-encryption tool. Type or select any message, tap Encrypt, and Ding Dong rewrites it into a sentence that looks like ordinary language but means nothing to anyone else. Send it through WhatsApp, Telegram, Messenger, SMS, email — anywhere text goes — and the recipient drops it back into Ding Dong to recover the original.

NO ACCOUNTS. NO KEYS TO MANAGE. NO ADS. NO TRACKERS.

★ Inline encrypt and decrypt in any app
Long-press a message in WhatsApp, Telegram, Messenger, Signal, or any other Android app. Tap "Decrypt with Ding Dong" from the floating toolbar — the encoded text is replaced with the original right where it was. The same flow works in reverse to encrypt outgoing messages.

★ Custom keyboard with Encrypt and Decrypt keys
Switch to the optional Ding Dong Keyboard while typing in any chat. Type your message, tap Encrypt, and the field's contents are replaced with the encrypted version, ready to send.

★ Share-sheet integration
Receive a Ding Dong message in any app? Long-press → Share → Ding Dong → tap Decrypt. The result lands on your clipboard, ready to paste back.

★ Reversible by design
Every encoded message decrypts cleanly back to its original form. No data lost, no rounding, no surprises.

★ Friendly output
Encoded messages still read like sentences — playful, harmless, and never raise suspicion at a glance.

★ Generous limits
Up to 2,056 characters per message — comfortably more than a tweet.

PRIVACY
Ding Dong does not store your messages. The text you tap to encrypt or decrypt is sent to our server over HTTPS to perform the conversion, then discarded. We retain a minimal log of the conversion direction and IP address for rate-limiting and abuse prevention only — retained 30 days, then deleted. No analytics SDKs, no advertising IDs, no third-party trackers. Full policy at https://dingdong.tel/privacy.

WHAT IT'S FOR
Ding Dong is "soft" encryption — fun, casual privacy for surprise messages, inside jokes, light obfuscation, and keeping a glance-reader from snooping. It is NOT a substitute for real cryptography (AES, PGP, Signal, etc.) and should not be used for sensitive data, secrets, or anything where strong cryptographic guarantees are needed.

What’s new

First release. Encrypt and decrypt messages from anywhere on Android — long-press any text and pick "Decrypt with Ding Dong" from the floating toolbar, use the share sheet, or switch to the Ding Dong Keyboard while typing. No accounts, no trackers, no ads.
