AbsentKey is a mobile encrypted vault designed to securely store sensitive information such as passwords, photos, files, notes, recovery codes, and IDs directly on a user's device. It addresses the need for privacy and secure sharing by encrypting data locally using AES-256-GCM, with encryption keys that never leave the device. The tool operates offline after unlocking and does not require an account for use, making it accessible for individuals seeking to safeguard personal data without relying on cloud storage or external servers.
The platform offers unlimited storage for secrets in its free version, supporting various types of content including text, files, and photos. For those who wish to share stored secrets, AbsentKey provides a paid upgrade that enables users to select up to five recipients per secret and set individualized sharing rules. These rules allow for instant access, approval-based sharing, or delayed release after a waiting period ranging from one day to one year. A dead man's switch feature ensures that, if the user becomes unresponsive, designated recipients receive access according to the pre-set waiting time, providing a safety net for inheritance or emergency scenarios.
Security is a central focus, with a zero-knowledge architecture ensuring that only encrypted data is stored on AbsentKey's servers, and all decryption occurs on the user's device. The tool supports biometric authentication methods such as Face ID and fingerprint recognition, and offers optional encrypted cloud backup for premium users. The source code for the mobile client is open and available on GitHub, allowing for public auditing of its cryptographic implementation.
AbsentKey is available as a free download for mobile devices, with the core vault functionality offered at no cost and no payment required. 99 per year, both with a 7-day free trial. The service is positioned for a range of use cases, including personal privacy, family password sharing, crypto inheritance, and secure collaboration for journalists and couples.
