Single-use file links that disappear after opening
Burn After is a highly secure file-sharing tool designed for those who need to send sensitive documents without leaving a digital footprint. It enables users to generate single-use, self-destructing links for files such as tax documents, IDs, contracts, and PDFs, ensuring that once the recipient opens the link, the file is automatically deleted and the link expires. This approach minimizes the risk of data leaks and enhances privacy, making it ideal for confidential exchanges. No recipient registration is required, simplifying the sharing process while maintaining security. Burn After's focus on ephemeral file sharing addresses the growing need for privacy-conscious communication in professional and personal contexts, offering peace of mind that sensitive information won't linger indefinitely in inboxes or cloud storage.

Cons
- Limited to one-time access, which may not suit all sharing needs
