Whether it's Hello or Goodbye, only you can read it.
We want to make the internet more human and private. We're modernizing our favorite things from the internet, both early and recent, and adapting them for the privacy needs of the world today.
What's Available Today? Lots!
... and we're just getting started! Check out our live roadmap and timeline, vote on ideas, or even submit your own feature proposals!
DMs and Group Conversations
Direct and group (up to 50 users) messaging, with audio, video, and screensharing. File uploads, disappearing messages, pins, local search, adjustable colors & labels for members, and more! Add any conversation to folders or favorites!
Largest Filesize Limits
Our lowest filesize limits start at over 1.3GB (nearly 3X the size of Discord, Fluxer, and others' largest limits), with our higher tiers offering over 9GB limits (larger than any mainstream chat app).
Everything: Encrypted
All messages and audio/video calls are fully end to end encrypted, resistant to quantum computing and include optional forward secrecy. Only you and your recipients can view the contents.
Audio, Video, Screensharing
Fully encrypted audio and video calls with screensharing (including on Linux), dynamic layouts based on participants, multiple pinning types, and more.
Express Yourself
Dedicated, customizable profile pages; custom, shareable app themes with dozens of controls; custom emojis; even customize the buttons and placement of your message composer!
Privacy Controls, Everywhere
Built from the ground up with privacy in mind: customizable controls for links and embeds (allowlists, stripping tracking from links), profiles, even GIFs/sticker display. Blocking/reporting also included (of course).
Cross-Platform, Mobile
Mobile-friendly browser app, or get additional features on desktop in Windows, macOS, and Linux. We use Linux every day, so we're particularly passionate about first-class support for all *nix systems.
Vote and Propose Features
Vote on community features, or submit your own proposals! We submit all official features for community feedback, too - we use your votes to prioritize what the community wants!
Native Notifications & Sounds
Not all notifications are the same! Adjust volume, or choose individual sounds for default notifications, mentions, ringtones, disappearing messages, etc. Pick from over 50 presets, or use your own!
Radical Transparency
Our source code is publicly auditable today, and our roadmap includes establishing regular, public financial disclosures and other transparency measures. We want our operations to be as open as our code.
In-App Human Support
Submit a ticket in-app and get support from real humans: no yelling into the void or screaming at bots. Alternatively, you can email us (say@adieuu.com) and get the same.
Self-Hosting Options
Self-host our entire platform in your own AWS infrastructure (now) for personal or non-commercial use, compatible with our desktop client (soon)! Licensed under PolyForm Noncommercial License 1.0.0.
No Ads, No Mining, No MTX.
We have an annual subscription (starts as low as we can while covering costs). There's no ads, no data mining, no micro-transactions: just the features you want for the annual cost of a nice dinner.
Referrals & Sponsorships
Want in but can't afford a sub? We get it! Ask for a sponsorhip in-app and others can support you. We also periodically select sponsorships for subscription gifts! Referrals grant referrer a month of Access!
... and much more on the way!
We've spent the last several months building in what we believe are the right foundations for a modern social platform. We have dozens of other features planned and in-progress! In 2026, with mounting concerns over surveillance, ID verification, manipulation by bots, (just to name a few!): there's no better time to start taking back control. We're the first platform that can comply with nearly all age verification laws without affecting your privacy, and our unique architecture balances anonymity with accountability.
A new privacy standard, without compromising
We're the only platform that completely separates who you are (your Account) from what you say and do (your Alias). We can't read what you said: we don't even know that you said it!
Here's what this means for you:
Unlinkable, Not Just Anonymous
Your Alias(es) can't be linked back to your Account. Even a full database breach can't connect your activity to your real info. Other services might offer deep encryption, but they still leak information about activity, relationships, and more. Adieuu's the only platform that foundationally separates your Alias and your real info.
E2EE, Forward Secrecy, and PQC
All the acronyms! In a nutshell: your messages, voice, and video (and most metadata) are fully end-to-end encrypted (optionally with keys that expire), and further wrapped with crypto that is resistant to quantum computers. Many modular layers of protection, even against future attacks!
Zero-Knowledge Server, Auditable Source
Your keys aren't shared with us: they stay on your device and encrypt messages before they reach our servers. Most other platforms (and their friends) can read your messages any time they want; or, even if they offer E2E encryption, they still know who you sent it to (and can maybe guess what you said)!
For the more technical folks
Don't take our word for it: our source code is fully public. See for yourself, or ask your techy friends to verify.
