QAKU — the duck is out of the bag

What's in the bag

A whole Q&A.
None of the server.

Run a talk, an AMA, a classroom, a town hall — anywhere people have questions and you want the best ones to float up. Simple, private, and yours.

Ask & upvote

Anyone with the secret posts a question and upvotes the good ones. The crowd sorts signal from quacks.

Answers, accepted

Hosts answer and mark the accepted one. Every answer shows who wrote it and when.

End-to-end encrypted

The room secret is the key — it derives the topic AND the encryption. Sealed before it leaves your device.

Offline-first

Your Q&A lives on your device. Post with no signal; it syncs the moment you're back. Never leaves the pond.

Verifiable authorship

Every message is signed with your own key. A little ✓ means it's provably that author. No impersonating the host.

Pick a pseudonym

Show up as a friendly name — or stay pseudonymous. Your identity is a keypair, not an email.

Owners & admins

The creator owns the room and appoints admins to answer and moderate. Open or close in a tap.

Share with a QR

Hand someone the room by scanning a code. The secret rides inside — join and sync in seconds.

Phone & desktop

An Android app and a Logos Basecamp desktop module, syncing directly with each other on the wire.

How it works

No server.
No middle-duck.

Most apps route your questions through someone's database. QAKU doesn't have one. Devices talk directly over a public peer-to-peer network, and each folds the messages into the same answer — like everyone doing the same crossword and always getting the same grid.

Host, moderate, project the room

Notice what's missing? ~~a server that reads your data~~ — there isn't one.

🔐 The secret is the key

A room is a 32-byte secret. It derives the network topic AND the AEAD key, so the relay only ever moves opaque sealed bytes. Have the secret, you're in — nobody else reads a thing.

🧩 Event-sourced & conflict-free

Every action is a small signed event. Each device merges what it hears and folds it deterministically (a CRDT with HLC clocks) — everyone converges, whatever the order or offline gaps.

🛰️ Reliable channels over Waku

Messages ride Logos Delivery's SDS Reliable Channels — ordering, gap-detection and retransmit on top of Waku's censorship-resistant relay. Miss one, it's backfilled.

✍️ Signed by you

Each event carries a secp256k1 signature; your address is your public key. Authorship is provable, and privileged actions are locked to owners & admins.

🐤 Yes, it's a rubber duck. Yes, we debugged it by talking to it.

Get it

Waddle over
& install.

QAKU rides the Logos app ecosystem. Add the repo once; updates roll in automatically.

📱 Android

Grab F-Droid, then Settings → Repositories → + and scan this (it carries the signing fingerprint, so the add is verified):

…or paste the repo URL:

https://vpavlin.github.io/logos-apps/fdroid/repo?fingerprint=2373710A76ACB09F287F053E99E533F9D3685529C44E9027CDBC79B1DC0C9105

Then search QAKU and install.

🖥️ Desktop

QAKU runs as a module in Logos Basecamp. Open Settings → Package Repositories and add:

https://raw.githubusercontent.com/vpavlin/logos-apps/refs/heads/main/basecamp/logos-repo.json

Install qaku from the catalog (it pulls in the core + delivery module it needs), open it, create a Q&A, and share the QR to your phone — they sync directly.

Source & releases on GitHub.

Using it

Four flaps and you're flying.

Create a Q&A

QAKU mints a fresh secret — that secret is the room. Add a title (and a name for yourself, if you like).

Share the secret

Show the QR or send the link. Anyone who scans it joins and syncs. Keep it to your audience.

Collect & curate

Questions roll in, the room upvotes the best. Sort by top, hide noise, post answers, mark the accepted one.

Close the bag

Done? Close the room. Everything stays on your devices — nothing to delete from a server, because there never was one.
