What to include in your message
Clear technical details make an issue easier to understand and reduce unnecessary follow-up.
- Page or feature
- Include the page URL and identify the upload workflow, manual calculator, result section, guide, or other feature involved.
- What happened
- Describe the expected behavior and the actual result. Include the exact error message when one is shown.
- Technical context
- For interface problems, include the operating system, browser name, browser version, and whether the issue occurs repeatedly.
- Safe supporting material

Email and privacy
Share only the information needed
Email is not an appropriate channel for passwords, access credentials, financial information, identity documents, or unrelated personal data.
A Windows battery report may contain device and usage information. Do not attach a report to an email unless it is genuinely necessary and you have reviewed the file first.
For an analyzer error, begin with the exact message, browser, operating system, and steps that produced the problem. A report file may not be required.
