These pages are for reading when you want to understand the app rather than get a task done. They explain the design choices, what the app checks and what it leaves to you, so you know which figures to trust and which to look at twice.
If you have a task in front of you, the how-to guides are quicker. For exact names, columns and limits, see the reference.
How it works
One Worker, one bucket, one database, no queues or scheduled jobs, and how search, the PDF viewer, the installable app and Undo fit in.
How reading works
How Clairic reads a receipt, what the code checks afterwards, and why rows get flagged.
How costs are sorted
Vendor rules first, Clef as the fallback, and what happens when rules disagree.
How matching works
Bank rows and receipts: automatic matches, suggestions, exemptions and transfers.
Currencies and reference rates
Where each euro amount comes from, and why a bank match beats an ECB rate.
Email and sender trust
The allowlist, SPF, and why unproven mail is kept but not read.
Privacy and your data
What runs where, what Nuits sees (nothing), and what leaves your Worker.
Running costs
What you pay Cloudflare for, and when you need Workers Paid.
What it does not do
Not bookkeeping, not advice, not a records system. The no-warranty notice in plain words.
For accountants
How the figures in the month you received were produced, and what to check.
