Kryptis vs the other photo vault apps.
Kryptis encrypts media and metadata with AES-256-GCM, which also detects tampering. Compare that design, backups and recovery with the published details from ten photo vault developers. AES-256 alone names the cipher and key size; it does not identify the encryption mode.

Published by Tuvo Labs, the maker of Kryptis. This comparison describes public documentation, not an independent security audit. Listings were checked September 6, 2026; later checks are noted below. A check means the feature is documented, a phrase gives the documented details, and an X means it was not found in the reviewed sources. An X does not prove that a feature is absent. Kryptis is coming soon. App names, icons and marks belong to their owners.
