私密 PDF 银行对账单转换

What this note is about

Bank statements are too sensitive for vague promises, so the product has to be clear about retention, support, and AI processing.

A statement tells a story

A bank statement can show salary, rent, medical payments, subscriptions, travel, suppliers, family transfers, balances, and account details.

That is why the privacy copy on the site cannot be decorative. It has to explain how files are handled and what does not happen to them.

Short retention is part of the product

The converter needs temporary access to read the PDF and create the spreadsheet. It does not need to keep the original statement around as a product feature.

When AI is involved, a Zero Data Retention path should be required. Failing is better than quietly using a less private fallback.
