Your files
Statement, payments and orders CSVs are read by your browser. They are not uploaded, stored on a server, or sent to anyone. The PDF and XLSX are made in your browser too.
What is stored on your device
The amounts you type from the form, and whether the full reconciliation is open, are kept in your browser's local storage so they are still there if you reload. Clear your browser's site data to remove them. No cookies are set.
What the site records
An anonymous event is sent when a page is opened, when the tool is used, when an export is made, when the paid button is pressed, when a payment could not be confirmed, and when you send feedback. Each event holds four things: the event name, the page path, the time, and a short note (for example "pdf", or the feedback you typed). When a page is opened, the note holds the name of the site that linked you here (the host name only, not the page) and the source word in the link, if it had one. No IP address, no browser details and no file contents are stored. Events are deleted after 120 days.
The calculators, the checkers and the embeddable checker work the same way: what you type stays in your browser, and one "tool was used" event is recorded.
If you press "Report a column", the column names of the file that was not recognised are sent. Names only, no rows.
Payments
If checkout is switched on, payment is handled by the payment provider on its own pages. This site never sees card details. After you pay, the provider sends you back here with a payment reference. The site asks the provider whether that reference is paid before it opens the full reconciliation, keeps the reference in your browser's local storage so the result stays open on this device for a year, and asks again when you open a page with the tool. The reference is not stored on our side.
