A Nostr client that keeps your data on your own node.

No. It works — notes, media, threads, tips, Tor mode and history backup are all built and used daily — but it is pre-release software without packaged installers, and anonymous mode in particular is experimental. Treat it as something to try, not somewhere to put your only copy of anything.

No more than on any other Nostr client. Your notes are public and signed — anyone can read them and verify they came from your key. That is the point of the format.

What Nosdag protects is different: anonymous mode hides your IP and location from relays and peers, Monero keeps payment amounts and addresses off a public ledger, and direct messages are encrypted. If you need the content of a note to be private, do not post it.

Someone has to be holding a copy. Your node serves your data, so when it is off, your media can stop resolving for other people.

Three answers ship in the app: link a pinning service so a copy stays online, let the people who follow you host your account on their nodes, or accept that you are only reachable while you are running. Nosdag shows you which of these is true rather than implying your data is magically everywhere.

Yes. Paste your nsec at sign-in and your profile, follow list, and relays come with you — they live on relays, not in any one client. Post from Nosdag and people reading you in Damus, Amethyst, or anything else see your notes normally.

Sign in with an Amber bunker if you would rather not paste a key. Browser-extension signing is not available, because a desktop app has no browser extension to talk to.

A place for the data. Alongside the usual relay event, each note is stored on the IPFS node inside the app as a signed object that links to your previous one, and a small pointer on relays says where the newest one is. Anyone can follow that pointer and pull your whole history, verified against your key.

That is what makes the rest possible: media served from your node instead of an image host, long-form and history that survive relays dropping your events, and a portable archive you can back up as one file. It uses standard Nostr event kinds to do it, so nothing here breaks other clients.

Then the account is gone. There is no reset, no support address, no recovery — your private key is the account, and nobody else has it, which is the whole arrangement. Export it from Settings the first time you open the app and keep it somewhere offline.

Yes. On the Anonymous Mode page, point Nosdag at any running SOCKS proxy — a tor router, a Whonix-style gateway, or system tor — and it uses that instead of starting its own.

One trade-off: without control over that Tor instance the app cannot publish an onion service, so it can read the network but nobody can fetch your notes and media directly from your node while that setting is on. The app tells you this on the same page.

Because a tip on a public timeline is a public payment. Monero keeps the amount, the sender, and the receiving address off a readable ledger by default, which fits a social app better than a transparent chain does. Nosdag is Monero-only by design.

It is an Electron app, so Linux, macOS, and Windows all work in principle from source with Node 22+. Day-to-day development and testing happen on Linux, so that is the best trodden path today. Packaged, signed builds for all three are the next milestone.

No. The bundled node uses its own ports — API 5201, gateway 8201, swarm 4201 — specifically so it cannot collide with a standard IPFS Desktop or Kubo installation.

Everything you run is in the nosdag-pub repository, MIT licensed. Read it before you trust it with a key — that is a reasonable thing to expect of software like this.
