Misk is a patent-pending platform for securely preserving personal content and sharing it with the right people, either immediately or when the user can no longer do so. It helps keep important memories, documents, account details, instructions, financial information, and private messages from being lost or buried in everyday apps. Users can store files for ongoing access and instant sharing, or designate recipients for future delivery.

For future delivery, Misk checks for prolonged inactivity, contacts the user, and then asks trusted Key Holders to help confirm their well-being before releasing content. Recipients use a unique Shared Secret to access their delivery. The platform also offers an Emergency Pause, which can temporarily stop monitoring and future delivery.

Misk emphasizes privacy through on-device encryption, protected sharing, account verification measures, and recipient-specific safeguards. Its service is intended for people who want to prepare information and messages for loved ones, including parents, travelers, expats, people in high-risk situations, and seniors.
