Talk to us.

For fee corrections, calculator requests, bug reports or anything else, email:

privacy@kindus.cn

We read every message. Fee-rate corrections are especially welcome — if a platform has changed its pricing, please include a link to the official announcement or documentation so we can verify and update the affected pages quickly.

If there is a marketplace, fee type or pricing decision you would like covered, tell us the platform and the decision you are trying to make (for example, "eBay final value fees for clothing sellers in the UK"). Requests that help many sellers at once get built first.
