What to write about

• A file that does not open, or opens with a warning.
• A number that looks wrong, such as a distance or an ascent.
• A file format or a tool you need.
• A question about privacy or a request about your data.

If a file does not open

The message the tool shows helps most, so copy it into your email, together with the app or the device that made the file. Only attach the file if you are happy to share it, because an attachment leaves your device. The privacy policy explains what happens to emails.
