# Troubleshooting Crypto
# URL expiration
Your secure links and images will automatically be removed after a 30 day period of inactivity (30 days after the link was last accessed and viewed) to ensure they are not accidentally laying around after they've served their purpose.
# Google Cloud
Your static design images are securely stored as images in Google Cloud, with the same encryption used by many of Google’s production services, including Gmail and Google’s own corporate data. Please note, this doesn't apply to the "Figma Prototype" option, which is an embed hosted by Figma.
# VPN may be required in China
Please note, if you're in China, the license server may be blocked by "The Great Firewall of China". If you're seeing a license error, despite using a valid key, you will likely need to use a VPN to resolve the issue.
