Here are quick answers to things people often ask about Fluxer, from privacy to apps. Each answer links to a longer article with the details and sources.
Is Fluxer connected to Discord?
Fluxer is made by its own company, Fluxer Platform AB in Sweden, with its own open source code, and its founder has never worked for Discord. Its layout feels familiar on purpose, and people and whole communities can switch without learning a new app. Fluxer is also compatible with large parts of Discord's API for bots and developer tools.
Who is behind Fluxer?
Hampus Kraft started Fluxer as a high school project in 2020 and built it in private for years with a group of testers until fluxer.com opened to everyone in January 2026. It's run by Fluxer Platform AB, the registered Swedish company he founded, and it's paid for by optional purchases and donations, with no ads or data sales.
How is Fluxer built?
The people who build Fluxer understand and stand behind every change they ship. Our AI stance explains how we work, with public code and commit history you can inspect and the LLM usage policy that everyone contributing to Fluxer follows.
Why haven't I heard of Fluxer?
Fluxer started as a high school project in 2020, and fluxer.com opened to everyone as a public beta in January 2026. We haven't bought ads or run a marketing campaign yet, because we wanted fluxer.com to be stable and the mobile apps to be in the App Store and Google Play first. The Android app came out on Google Play on November 8, 2026, and our story says what comes next, including more posts and videos about new features.
Is Fluxer still being worked on?
Hampus works on Fluxer full-time, we post patch notes on our blog and we keep our roadmap up to date. We have no plans to shut down fluxer.com, and if Fluxer ever stopped, anyone could keep running its open source code on their own instance.
Is Fluxer reliable?
fluxer.com has been stable for months, and short disruptions still happen sometimes during denial-of-service (DDoS) attacks on our network or problems with our hosting. fluxer.com struggled in February 2026, when more than 100,000 accounts were created in 16 days while Fluxer still ran on a single server, and that was fixed quickly. Our status page at fluxerstatus.com shows the current status and uptime of fluxer.com.
Who runs r/FluxerApp?
r/FluxerApp and other Reddit communities about Fluxer are run by people in the community, and our team doesn't run or moderate any subreddit. Our company information page lists all of Fluxer's official accounts, and you can check which sources are official before you trust a post, a link or an account that says it speaks for Fluxer or for our team.
Why do old reviews and AI answers say outdated things about Fluxer?
Fluxer changes quickly, and many reviews and AI answers predate threads and forums, the open source mobile apps or the new self-hosting guide. We post patch notes on our blog, keep the roadmap up to date and list every policy change in our changelog.
Some answers online say Fluxer is hosted in Europe or is end-to-end encrypted, but neither is true today. Each answer here links to the policy or article its facts come from.
Does Fluxer read my private messages?
Fluxer doesn't read your private messages. A person on our team opens specific messages only when someone reports them, when we investigate a specific rule break, for a credible safety issue or for a valid legal request under section 14 of our privacy policy, and even then they open only the content involved. Fluxer doesn't record calls.
When you delete a message, it's removed from fluxer.com, usually within a few minutes. Copies of it in our encrypted backups, or a copy kept because someone reported it, are deleted within the periods that sections 7.3 and 7.4 of our privacy policy set out.
Does Fluxer scan my messages and images?
fluxer.com doesn't check your messages against lists of banned words or phrases, and it doesn't check your files against outside databases of known abuse images. To spot spam, automatic checks on fluxer.com look at signals such as how often messages are sent, the links in them, how old the sending account is and the reputation of its IP address.
Rules that our team writes from real abuse flag likely spam and scams for the team to look into. In some cases they limit an account that is very likely spam until a person on our team reviews it, and you can ask us to lift a limit if it was a mistake.
A link or file that a person on our team flagged as harmful can be blocked from being sent or uploaded again. When someone reports child sexual abuse material, a person on our team confirms it and Fluxer files a report with NCMEC's CyberTipline.
Your sensitive media settings decide whether explicit images are blurred or blocked for you, and an automatic check on Fluxer's servers tells the app which images are explicit. That check never punishes accounts or files reports about anyone.
Does Fluxer track me or sell my data?
Fluxer has no third-party analytics, no fingerprinting and no cross-site tracking, and we don't sell your personal data, as our privacy policy says. To keep accounts safe and to spot spam, fraud and abuse, we keep security records, such as the IP addresses you sign in from, only for as long as our privacy policy says we may keep them.
Does Fluxer train AI on my messages?
Fluxer never trains AI on your messages. Our terms say we never use your content to train, fine-tune or evaluate AI models, or sell or license it for anyone else's use.
Can other people see my IP address?
Other people and bots don't get your IP address from Fluxer, and regular calls go through our voice servers. In peer-to-peer calls the people in the call can see each other's IP addresses, and the app asks before you join one unless you chose to always agree.
Does Fluxer record my calls?
Fluxer doesn't record or store voice or video calls. When you share your screen, the app makes a small preview image by default so people who can join the call see what you're sharing, and you can turn it off when you start sharing your screen. The preview is kept for at most 24 hours, as section 7.1 of our privacy policy says.
Does Fluxer have end-to-end encryption?
End-to-end encrypted calls are planned with the new voice and video system in 2026. For notes, DMs and group DMs, it's planned as an experimental draft in 2026 and a stable release in 2027, and neither will have an off switch. Until then, nothing on Fluxer is end-to-end encrypted, and your data is encrypted in transit and at rest.
Is Fluxer hosted in the US, and does it send data to the US government?
We never hand over your data just because a government asks, including the US government, and section 4.3 of our privacy policy lists the limited cases where we disclose any data. A government outside the EU has to go through Swedish authorities, and when we get a legal request, we review it and tell you about it before we disclose anything in response, apart from the exceptions listed in section 14.
Today most of fluxer.com's stored data is hosted with Vultr in New Jersey, in the United States, and we're moving to our own hardware in Sweden. Our article on where your data is stored explains which US laws apply to data while it's hosted in the US.
Where is Fluxer based?
Fluxer is run by Fluxer Platform AB, a company registered in Sweden, and there's no US company behind it. Most of fluxer.com's data is hosted in the United States today, and we're moving fluxer.com to our own hardware in Sweden when it's ready.
Does Fluxer ask for ID or a face scan?
Fluxer never asks for or accepts ID, selfies or face scans to prove your age. The app asks for your date of birth when you sign up. In the UK and Brazil, you can choose to unlock mature content with an accepted 18+ result from Apple or Google. Sharing it is always optional.
If someone reports you as under age, a person on our team looks at the report, and you don't have to send us any ID, a selfie or anything else to prove your age.
Will a new law force Fluxer to check my ID or face?
Fluxer never asks for ID or face scans, and that hasn't changed for any law. Where a law needs age checks for adult content, we lock age-restricted content in that region, and where it needs them for every account, fluxer.com is unavailable there. Here's how today's laws treat apps like Fluxer, including the KIDS Act, which isn't law.
Does Chat Control make Fluxer scan my messages?
Fluxer doesn't scan your messages or files for child abuse material, and as of October 2026 no EU law requires it to. The EU rule in force lets services scan only if they choose to, and the proposed law that people call Chat Control 2.0 is still being negotiated. Our article about scanning and Chat Control explains what fluxer.com checks today.
Can I use Fluxer in Brazil?
People in Brazil can sign up for Fluxer and use it, and only age-restricted content is locked there under Brazil's Digital ECA. You can unlock communities and channels marked 18+ when an age range from Apple or Google and your date of birth both say you're 18 or older, and Fluxer never checks ages with IDs, biometric data or CPF numbers.
Does Fluxer need my phone number?
You don't need a phone number to sign up or to use Fluxer, and texting a code is never the only way to lift a pause on messaging. If our spam rules pause messaging on your account, you can text a code from your phone to our verification number, or you can reply to the email and ask our support team to verify you by hand without a phone number.
Who handles reports, bans and support?
A person on our team reads reports, decides on bans and appeals and answers every support request you send. Our spam filters are rules our team writes by hand from known abuse patterns, and you can appeal anything they do to a person on our team.
The only machine learning that checks what you post is a small image classifier for your sensitive media settings. It tells the app which explicit images to blur or block for you, and it never punishes an account or files a report about anyone.
Can I be banned on Fluxer?
On fluxer.com, we enforce our terms and community guidelines, and you can appeal any decision we make. On a self-hosted instance, its own admins moderate it with their own rules, and Fluxer staff can't ban anyone from an instance we don't run.
Why did antivirus software flag older Fluxer builds?
Some antivirus software flagged older builds of the Windows desktop app because their screen sharing hooked into games to capture them. We removed that feature on August 29, 2026, and builds released since then don't hook into any games at all.
Does Fluxer have mobile apps?
Yes. The iOS and Android apps are open source, and the Android app is out on Google Play. Our TestFlight beta for iOS is on hold for now following a technical issue at Apple, and we expect Fluxer on the App Store in early November 2026. Until then, any Fluxer app you find in the App Store isn't one of ours, even if it uses our name or logo.
Is Fluxer still in beta, and do I need an invite?
You don't need an invite code, because sign-up on fluxer.com is open to everyone. A self-hosted instance can choose to approve each new account itself or to close sign-up. The Android app is out on Google Play, and our TestFlight beta for iOS is on hold for now. We expect the iOS app on the App Store in early November 2026.
Does Fluxer have threads and forums?
Yes. Threads, forum channels and media channels came out in early beta for everyone on October 16, 2026. Public forums are planned as an experimental draft in 2026, and today search engines can't find any of your messages or communities on Fluxer.
Can I share my screen with audio on Fluxer?
Yes. The desktop app can share audio with your screen on Windows, macOS and Linux, and in the web app it depends on your browser. On Windows, the desktop app can't capture some fullscreen games yet. Our new voice and video system, planned for 2026, will improve screen sharing further and fix a known cause of choppy screen shares.
Is Fluxer's desktop app slow because it uses Electron?
Using Electron doesn't make an app slow on its own, and how fast an app feels depends mostly on its own code. Fluxer's desktop app is built with Electron, and we explain why Electron isn't always slow and what we do to keep the app fast. For people who want a desktop app without Electron, we've started work on a desktop version of Fluxer Oxygen. If the app runs slowly on your computer, please report it to us as a bug.
Does Fluxer have bots and slash commands?
Fluxer has bots that can use the API and real-time gateway, join voice channels and respond to messages. Slash commands, components and interactions for bots are planned for 2026, and until then bots on Fluxer can use prefix commands. Fluxer is compatible with large parts of Discord's API, but a Discord bot has to be set up to run as a Fluxer bot.
Do I need Plutonium?
You don't need Plutonium to use Fluxer. Plutonium is an optional subscription that raises your own account's limits on fluxer.com, such as bigger uploads. Communities, voice and video calls, screen sharing and a community's own emoji and stickers are free for everyone, and no purchase upgrades a community or unlocks a feature for it.
Is Fluxer really open source, and could it go closed source?
The server, web app and desktop app are published under the AGPL v3.0 or later, and the iOS and Android apps have been open source since June 2026. Fluxer has had no CLA since February 18, 2026, so Fluxer Platform AB can't relicense work sent since then without its contributors. Every published version stays available under the AGPL, and our open source article also explains why the public repository was quiet in spring 2026.
Does Fluxer care about self-hosting?
Yes. Self-hosting Fluxer is free, and you get the whole open source Fluxer software with no license key, paid tier or reduced edition. There's also an official Helm chart for running Fluxer on Kubernetes, and the official desktop and mobile apps can connect to self-hosted instances alongside fluxer.com, and you can use both in one app. On a self-hosted instance, Fluxer has none of that instance's messages, files or accounts.
Is Fluxer federated, or based on Matrix?
Fluxer has its own API and real-time gateway and isn't based on Matrix, and each instance is separate from the others for now. Optional federation built on polyproto is on our roadmap as an experimental draft in 2026 and a stable release in 2027, and our roadmap post explains why we chose polyproto over Matrix for federation.
Do I need a separate account for every community?
One fluxer.com account can join many communities. You only need a separate account per instance, and the apps can sign in to several instances at once.
Are third-party clients, mods and themes allowed on Fluxer?
Yes. Fluxer welcomes third-party and modified clients, themes, custom CSS and automating your own account, and they stay allowed on fluxer.com as long as you don't use them to harm other people or the service. Our web and desktop apps stay on the web platform, where you can mod and theme them, and we plan more theming options for our Flutter app on phones, tablets and, once its desktop version is out, computers.
