Le Space Belege

Collect receipts, match payments, hand over a DATEV package — pre-accounting for your small business, entirely without the cloud: everything happens on your own computer, and the books stay encrypted on your device.

Open the app Source code

No cloud

  • The books live only in your browser, encrypted with a key your passkey creates anew each time you unlock. There is no account, no password, and no copy with us — we run no server.
    Hosted on IPFS — the proof, and how to verify it

    Only the app itself is served from IPFS — your receipts and data never live there; they stay local with you. There is no server of ours behind the PWA, and that is checkable: the latest deploy publishes the IPFS hash (CID), and the same app over the public inbrowser.link gateway is the same, byte for byte — there your browser verifies the delivery against the hash itself.

    If that matters to you: with your own IPFS node (Kubo) or the IPFS Companion extension, your browser fetches the app straight from the network — then not even the visit to belege.le-space.de can be logged anywhere. Entirely optional.

  • Account transactions come straight from your bank: German banks over FinTS/HBCI, with Hibiscus on the Jameica platform — no middlemen in between. For European banks under PSD2, Enable Banking is implemented but not yet field-tested. A small bridge on your own computer makes this possible; it also talks to the accounting mailbox, customer portals, exchanges and wallets, and nothing of it leaves your machine.

Crypto transactions

Every crypto movement becomes a booking in euros at the day’s rate, with its source named — ECB, Kraken, CoinGecko, Uniswap pools, the trade itself, or by hand. Swaps and migrations are followed across chains, and everything exports in an open, MIT-licensed ledger format.

Supported today

Blockchains
Bitcoin, Ethereum, Base, Arbitrum One, OP Mainnet, Polygon, Monero, Filecoin (USDFC), Akash, Nym (Nyx)
Exchanges
Kraken (read-only)
Decentralised archives
Aleph Cloud — optional and encrypted, sealed with a key from your passkey: only you can open the archive, and an empty browser gets everything back. Via the OrbitDB Storage Bridge (in progress: Filecoin, On-Chain Cloud, Lighthouse)

More on request — gladly.

AI, only on a click

  • Your model, not ours: Le Space runs no AI and sees none of your data. The bridge asks the language model you configure.
  • Our recommendation: a local model (Ollama, LM Studio) — or a TEE-hosted LLM whose attestation can be verified.
  • Every button that asks the model carries the ✦ mark, the text goes out redacted, and usage and cost stay in view.

Who it is for

Small businesses and the self-employed — especially when crypto is involved: income in coins as well as spending in utility tokens, say for Filecoin, Akash or Aleph services. The monthly DATEV package goes to your bookkeeping software or your tax advisor; the actual posting happens there.

Get going in two minutes

  1. Open belege.le-space.de and create a passkey — that is the whole set-up.
  2. Even without the bridge: load the built-in sample data and try everything — one click removes it again — or upload a bank statement (CAMT.053) right away and start matching.
  3. For bank, mailbox, portals and AI, the bridge comes onto your computer — and we set it up with you.

Open source, on purpose

  • Built in a few weeks — with substantial AI assistance. What can come into being this fast, we have no need to fence in: a fence protects nothing there any more. The value is not in the code but in the trust that it does what it promises — and that can only be checked when it lies open.
  • That is why Belege is open source, under the AGPL-3.0: anyone can use the app for free, inspect it, develop it further independently — and those developments benefit everyone.
  • And if building is not your thing: we gladly take on adaptations, customisation and automation — as a service.

More features

  • Several devices, and collaboration: the receipts replicate peer-to-peer between phones and computers, over libp2p and OrbitDB, optionally — in the same room by QR code, on your own network through the bridge, or elsewhere over relays. A new device only joins after proving the passkey, and coworkers get a time-limited read grant
  • Installable as a PWA — the shell works offline
  • E-invoices (XRechnung: UBL and CII) read and kept as the original
  • Eigenbelege — for crypto with hash, both addresses and gas
  • Customer portals as a receipt source, recorded once
  • Vendor accounts for credit and collective statements
  • Private payments from the business account: marked and settled
  • DKIM, SPF and scam checks on receipt mail
  • One fiscal year at a time, with a year switch
  • SKR 03 and BU keys; your own chart of accounts can be read in
  • German and English, switched at once
  • VAT overview (planned)
  • Travel expenses (planned)
  • Paperless-ngx as a receipt source (planned)

Set-up and adaptations

We set Belege up with you — bridge, bank access, accounting mailbox, customer portals, your own language model — and we build adaptations: further blockchains and exchanges, special cases, and automation of business processes, like invoicing straight into the books over UCEP. This is a paid service; write to us.

Belege is tailored to the German market today — SKR 03, VAT, DATEV. The pattern carries further, though: receipts, payments and a monthly package for the bookkeeping exist everywhere. For adapting Belege to other countries and tax systems, we are looking for partners.

belege@le-space.de

Still early — keep storing your statements and receipts somewhere else as well. Which is exactly why we accompany the start.
