What to provide after external reporting opens
Use only a contact channel explicitly shown on the site at that time. If no contact entry is displayed, the current version is not yet accepting external reports. Do not send passwords, API keys, complete identity documents, or other sensitive information to an unverified address.
- The full page URL and language where the issue appears.
- Calculator inputs, the displayed result, and the time observed.
- A publicly accessible official source URL and the statement or value you believe conflicts.
- Browser and device details only when the issue may be interface-related.
How reports are assessed
The order is: reproduce the issue, then check the formula, the stored record and the applicable conditions. A reproducible calculation error is added to the pre-release checks so the same class of error cannot ship again. If the difference comes from account tier, region, time or a live venue change, the page clarifies its limitation or data state instead of claiming access to account information it does not have.
How corrections are recorded
A material error affecting cost, risk, regional eligibility, or venue selection should leave a dated entry on this page after correction, naming the affected page, the error, and the change. Typography or wording fixes that do not change meaning may be corrected without an individual log entry.
- A correction date is not backdated to the original publication date.
- When a conclusion changes, the record explains the difference between the former and corrected content.
- When immediate verification is not possible, the affected claim is limited or paused first.
Public correction record
There are currently no material corrections to list. Future corrections meeting the standard above will appear here in reverse chronological order; ordinary content updates are not mislabeled as errors.
Frequently asked questions
Will every report result in the requested change?
Not necessarily. The team verifies the formula, source, and conditions. If an issue cannot be reproduced, it may request more non-sensitive information or retain the content with a clearer limitation.
Is a normal fee change a correction?
Not necessarily. If the page clearly shows an observation time, a later market change is usually a data update. If an old value is incorrectly presented as current, its data state or content needs correction.
