Backup to secure cloud storage.
Everything is encrypted automatically.
You alone possess the decryption key.
Accidental deletion, hardware failure and theft are facts of life. Backups stored in the cloud prevents losing your photos due to physical disasters.
Photos found on the Internet are often exploited by criminals, by businesses without proper consent and by government surveillance programs. Encryption prevents these harmful infringements on privacy.
Encryption is done on your own computer. The key is never sent on the Internet so we cannot view your images, even if we wanted to.
