Encrypt financial spreadsheets — bookkeeping without a portal
Small-business finances live in a few spreadsheets and a mess of PDFs. Elba lets you keep the lot in a sealed folder on your own machine — no accountant portal, no cloud spreadsheet, no monthly seat fee.
A vault per fiscal year
Ledgers, invoices, receipts, payroll, and VAT paperwork sealed together. Cloud backup of the sealed folder is safe.
Working with an accountant
Unlock, export the specific reports needed, re-lock. The accountant sees the numbers; the rest of the archive stays in the box.
Questions people actually ask
- Does Elba open .xlsx files?
- Elba encrypts and decrypts files; you open them in your normal spreadsheet app once the vault is unlocked.
- What about live-shared sheets?
- For live collaboration you still want Google Sheets or similar. Elba is for the archived, private copy.
Take the island
Elba is one HTML file. It runs locally in a Chromium browser, seals a folder with AES-256-GCM, never phones home, and becomes open source on 1 January 2030.
