The safest category: content you created
Exporting your own original Posts and media for backup or reuse is the clearest starting point. Confirm that you also own or licensed every included photograph, clip, song, graphic, and quotation. Creating the Post does not necessarily give you rights to material incorporated from someone else.
Permission is better than assumption
If another person created the work, ask for permission that covers what you plan to do: download, edit, republish, monetize, or distribute. Preserve the permission record. A credit is respectful, but attribution alone is not a substitute for permission.
Fair use is contextual
In the United States, criticism, commentary, reporting, teaching, and research can sometimes qualify as fair use. There is no automatic safe percentage or number of seconds. Commercial purpose, transformation, the nature of the work, the amount used, and market effect are among the factors considered.

Follow Checker’s planned export boundary
Any future exporter will prioritize the signed-in user’s own content, use official interfaces where available, exclude protected or deleted material, preserve attribution, and avoid permanent server storage. This boundary is also recorded in the site’s copyright policy.
Before republishing
- Identify who created every part of the work.
- Confirm ownership, a license, permission, or a well-supported legal exception.
- Preserve attribution and rights information.
- Check whether people shown in the media have privacy or publicity rights.
- Consider legal advice before commercial or high-visibility reuse.
