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 in your browser.

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.
  • 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.
  • Receipts are kept locally and archived decentralised and encrypted — sealed with a key from your passkey, stored on Aleph Cloud. Only you can open the archive, and an empty browser gets everything back with the same passkey.

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.

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.

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.

Still early. Keep storing your statements and receipts somewhere else as well.
