At Lifecraft, we believe that privacy is a fundamental human right. Lifecraft is designed from the ground up to safeguard your information. That's achieved through encryption at the device level in combination with iCloud encryption. The result is a true zero knowledge encryption system.
- Lifecraft is built on an industrial strength Realm database.
- When you first run Lifecraft, it asks you to choose a password. This password is saved to the system Keychain, which is encrypted. If you don't lock Lifecraft, it will retrieve the password from the Keychain. If you do lock Lifecraft, you have to manually enter your password (or use TouchID or FaceID) before you can view your Lifecraft data.
- Lifecraft generates an encryption key that is used to encrypt your data while it's sitting on your device.
- When Lifecraft syncs, it sends encrypted data to iCloud. It's impossible to intercept and view your data while it's being transmitted to iCloud.
- iCloud then encrypts the data a second time (so it's actually double-encrypted while it's in iCloud).
- The Lifecraft encryption key is also synced to iCloud. This allows Lifecraft to automatically sync data between your different devices.
To be truly secure, all links in the communication chain must be strong. That's why Lifecraft uses iCloud for syncing. iCloud supports End-to-End Encryption which is the highest level of data security. Your data is protected with a key derived from information unique to your device, combined with your device passcode, which only you know.
To use end-to-end encryption in iCloud, you must turn on two-factor authentication for your Apple ID.
Zero Knowledge Encryption
Some companies use their own servers to sync your information. They promise not to access your information unless it's needed for "technical support" or they're "legally required" to do so.
With Lifecraft and iCloud, it's impossible for anyone else to access your data. That's why it's so important that you not forget your Lifecraft password. If you lose your password, no-one will be able to access your data (including Lifecraft and Apple employees).
