Another assistant

Any other assistant that takes a Model Context Protocol server by its address takes the same one.

One thing, which a visitor to this site can do too.

A check of your header rows

Give the header row of each file a month-end close is made from: the first line only, no client data. That means no names, no balances and no transactions. The answer says, field by field, what is present, what is missing and what to ask whoever produces the export. It goes by the words in the column names alone. A file given with any line after its header row is refused. A header row cannot show whether a column is filled, how dates and decimals are written, or whether an identifier repeats. There is no charge. The header rows are not kept. Nothing in the reply is accounting or tax advice.

What your assistant sends to a tool reaches us. The rest of the conversation does not, and we do not ask for it. The company that makes the assistant handles the conversation under its own terms, which are not ours.

Header rows are read to make the answer and are not kept.

We count how many times each tool is used in a day, and keep the count for 90 days. The count holds no address and nothing that was sent.

Everything else Web3 Close keeps is in the privacy notice, linked at the foot of this page.
