Privacy and security

What Fluxer can and can't see, how your messages and data are protected, where they're stored and how to keep your account secure.

Who can read your messages, and what Fluxer checksNobody at Fluxer reads your messages except in four specific cases. What our automated checks look for, how reports work and where Chat Control stands.
End-to-end encryption on Fluxer: what's encrypted today and what's comingFluxer encrypts your data in transit and at rest. End-to-end encrypted calls are planned for 2026, and encrypted notes, DMs and group DMs for 2026 and 2027.
Is Fluxer safe? How we keep Fluxer and your data secureHow we protect Fluxer and your data, from security testing since 2023 and audit-logged staff access to encryption, two-factor sign-in and signed downloads.
Does Fluxer track me or sell my data?No. Fluxer has no third-party analytics, no fingerprinting and no cross-site tracking, runs no ads, doesn't sell your data and never trains AI on your content.
Where your data is stored and who can get itFluxer is run by a Swedish company and the GDPR covers all your data. Most of fluxer.com's data is in the US today, and we're moving it to our own hardware in Sweden.
Is a self-hosted Fluxer instance more private?On a self-hosted instance, Fluxer has none of its messages, files or accounts. The people who run it decide where its data is stored and who can access it.
What other people and bots on Fluxer can see about youOther people and bots don't get your IP address from Fluxer, except in opt-in peer-to-peer calls, and an app only gets your email address if you allow it.
What happens when I block someone on Fluxer?Fluxer doesn't tell the person you block. Neither of you can send the other a DM, and their messages in communities you share collapse into one row.
Does Fluxer have read receipts?No. Other people on Fluxer can't see whether you've read their message, and read receipts aren't on our roadmap.
Does "Invisible" hide me completely on Fluxer?No. "Invisible" makes you appear offline, and people still see the messages you send and see you when you join a voice channel.
Can other people see my IP address on Fluxer?Other users can't see your IP address in text chat or regular calls. Peer-to-peer calls and links to outside sites are the cases to know about.
Two-factor, passkeys and signed-in devicesFluxer supports authenticator apps, passkeys, security keys and backup codes. If you lose your second factor, a backup code gets you back in.
Lost your 2FA app or passkey? How to get back into FluxerUse a backup code if you saved one. Otherwise write to support from your account's email address, and a person on our team will help.
How do I sign out my other devices on Fluxer?You can sign out one device or every other device from "Linked devices", and changing or resetting your password also signs out your other devices.
Why does claiming a gift on Fluxer need a captcha?Claiming a gift asks your device to work out a small calculation that makes it harder for bots, with no puzzle and no third-party captcha service.
Why did my antivirus flag Fluxer?A Windows build that hooked into games for better screen capture was flagged by some antivirus software. We removed that feature, and Fluxer isn't malware.
Is Fluxer Canary safe? What the early-release app isFluxer Canary is our own early-release desktop app, where new changes show up first. It's signed like the regular app, and some antivirus apps flagged an older build.
How do I check that my Fluxer download is genuine?Download Fluxer only from our download page or GitHub, check the signature on Windows and compare the .sha256 checksum from pkgs.fluxer.com.
