Freedom of speech needs infrastructure that protects it by design - protocols, governance and funding.
v6.5 release brings SimpleX Channels: a new model for online publishing built for participation privacy:
- channel owners hold their own channel keys,
- each channel uses multiple relays for reliability,
- publishers can run their own chat relays,
- channels can be added to our SimpleX Directory (https://simplex.chat/directory).

We updated SimpleX Chat Privacy Policy and Conditions.
What changed:
Stronger privacy commitments:
- explicitly states that preset servers do not log IP addresses.
- you can verify clients and servers via reproducible builds. quantum-resistant end-to-end encryption.
- messages are irreversibly removed from preset servers on delivery or after 21 days.
- transparency commitment by client apps.
New private one-time connection links and public addresses:
- your profile data is encrypted on the server - only people with the link can access it, not the servers.
- one-time link profile data is removed once the connection is established.
Public channels (beta):
- chat relays are used to deliver messages to channel subscribers.
- chat relays cannot identify subscribers.
Commit with the change: https://github.com/simplex-chat/simplex-chat/commit/05f99634c470f8bddac20046947a0606938b22ad (we maintain it in GitHub so you can track changes).

A big news for SimpleX Chat privacy and security:
Android apps released via GitHub and F-Droid are now 100% reproducible!
It means that you can easily verify that the app is secure, even if the download site was hacked.
From v6.5 our release process is:
- build Android apps on two independent machines and confirm they are 100% identical;
- cryptographically "sign" them;
- add signature files to the release page so you can verify.
v6.5 beta.3 release: https://github.com/simplex-chat/simplex-chat/releases/tag/v6.5.0-beta.3
Server and Linux desktop builds were already reproducible, and Android APKs are now as secure.
Anyone can check it themselves - no coding needed, just follow our simple guide to verify the app is genuine or run the build yourself: https://simplex.chat/reproduce/

Our users asked many questions about Chat Control, as discussions were restarted in the EU this week.
SimpleX Chat is an open-source app where users control the code and the servers they use.
Therefore it is impossible to implement any client-side scanning, and it will not happen.
If the law is passed, two options are possible:
- we might need to stop offering preset servers to the EU users.
- we will not need to change anything - this is the most likely outcome.
Our operations are always consistent with our Privacy Policy (https://simplex.chat/privacy), and we would rather shut down than do anything that contradicts this agreement with our users.

"Code alone doesn't cut it. Not code alone, not code widely distributed, not even code widely used. Some measure of toleration in society for activities conducted in private is necessary for long term success. Not convenient, not easier, but necessary."

Huge thank you to all for feedback and suggestions on Community Vouchers plan!
FAQ:
- Can we still use our servers?
Yes, and it will be improved (read full FAQ). Community Vouchers are completely opt-in, and intended only for server payments by the large groups.
- How is it possible to provide privacy on public blockchain?
In the same way as we provide private communications on the public Internet - by using per-purchase addresses, not per user as in wallet apps, and by using zero-knowledge proofs to verify ownership.
- How many Community vouchers will be pre-sold and available during public sale?
None! No Community Vouchers will be made available to any insiders or to the public sale – it would have made them investment contracts. Community Vouchers are restricted utility tokens.
- What problems do vouchers solve?
- unlinkability of purchase to usage, thanks to zero-knowledge proofs.
- trust to server operators - funds will be only unlocked to them after infrastracture is provided.
- revenue sharing with network - it will be codified in blockchain contract.
- Are you considering other blockchains?
Yes, as long as they are sufficiently mature, and natively support smart contracts and zero-knowledge proofs. Send your suggestions!

An essay explaining why we don't plan to use MLS: https://www.poberezkin.com/posts/2025-08-12-mls-the-naked-king-of-end-to-end-encryption.html
A sidenote, is that Nostr's Whitenoise avoids its main problem.
TL;DR: MLS security model is "Trust me bro".

We updated SimpleX Chat Privacy Policy & Conditions of Use.
It's more Power to the People!
-
Added content license in groups, and stated that NO LICENSE is granted to the server operators or ourselves. We do not ask for ANY license to YOUR content!
-
Added the conditions of access to preconfigured servers via modified 3rd party applications.
The previous policy version prohibited it, unintentionally.
Thanks to the users developing apps for suggesting it!
- Clarified some definitions:
- "aggregate statistics" explicitly excludes any stats that can be related to particular users.
- the content that can be removed changed from "identified illegal content" to "illegal content identified in publicly accessible resources".
These changes do not change how we work: we never had user-related statistics, and we technically and legally cannot access private chats.
Our privacy policy also:
- includes a commitment to run the published code,
- re-confirms the absence of any compulsory requests.
Thanks to all users for suggesting these changes.
