Le Space Belege

No cloud

• The books live only on your device, 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 release run publishes the IPFS hash (CID) in its summary, 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.

  How the pieces connect: the release run publishes the build's hash, the CID. Linking the domain writes exactly this CID into the DNSLink record of belege.le-space.de — and the IPNS address at inbrowser.link reads nothing but that record. You can check it right now: dig TXT _dnslink.belege.le-space.de has to show the CID from the release; with Kubo, ipfs resolve /ipns/belege.le-space.de does the same. And https://<CID>.ipfs.inbrowser.link/ or https://ipfs.aleph.sh/ipfs/<CID>/ serve that very build with no domain in between.

• 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)

E-invoices

XRechnung (UBL and CII) and ZUGFeRD/Factur-X under EN 16931 — read and kept as the original; issuing them follows in the invoicing app

Decentralised archives

Aleph Cloud — optional and encrypted, sealed with a key from your passkey: only you can open the archive, and a new device 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) and ZUGFeRD/Factur-X — uploaded or from the mailbox, read at once without AI: seller, number, dates, VAT per rate, lines, total; credit notes and reverse charge recognised. The XML stays the original and travels as such into the DATEV export, backups and a book move
• Issuing e-invoices — currently in development in the invoicing app
• VAT on the home page: input VAT from the receipts and output VAT from your own invoices per month, quarter and year, the payable or refund — including intra-EU supplies with the lines for the EC Sales List, third country, §13b and the small-business limits. A help for the advance return, not the return itself
• Travel expenses: trips with their receipts and the statutory per-diems by hours and country, one statement per month as a PDF on SKR 03 travel accounts, the payout linked to it
• Matching by a score from amount, invoice and customer number, IBAN, vendor and date — transfers, fees, refunds and your own rules need no receipt
• 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
• Move the books to another passkey — by a one-time key as a QR code, or by a passphrase
• 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
• Paperless-ngx as a receipt source (planned)
