To host your images and videos, {% data variables.product.product_name %} uses the [open-source project Camo](https://github.com/atmos/camo). Camo generates an anonymous URL proxy for each file which hides your browser details and related information from other users. The URL starts `https://<subdomain>.githubusercontent.com/`, with different subdomains depending on how you uploaded the image or video.

The URL starts `https://<subdomain>.githubusercontent.com/`, with different subdomains depending on how you uploaded the image.
Videos also get anonymized URLs with the same format as image URLs, but are not processed through Camo. This is because {% data variables.product.prodname_dotcom %} only supports uploaded videos, and not externally hosted videos.
Anyone who receives your anonymized URL, directly or indirectly, may view your image or video. To keep sensitive media files private, restrict them to a private network or a server that requires authentication instead of using Camo.
