Cacti is an AI-Powered Photo Vault.

Store your private and intimate photos on Cacti's on-device 256-bit AES encrypted vault.

Cacti is powered by a strong AI to automatically detect private and intimate photos in your Photos Library. Our AI algorithm is years worth effort to help you find intimate photos easily. You don't have to browse through tens of thousands of your photos to find those that belong in a secure vault. Our algorithm will suggest photos that are most likely private and intimate so you can hide them in a few taps. The best part is that this AI algorithm works right on your device; your data never leaves your device; Cacti can work without access to the internet (provided your photos are not in iCloud).

Cacti allows you to store your photos in a highly secure 256-bit AES encrypted vault to ensure the privacy and security you need. Cacti Vault is protected by your passphrase. You may also use Touch ID, or Face ID to unlock your vault. You can also add photos that are not detected by our algorithm directly into the vault. To ensure there is no possible hacking, we do not allow your data to leave your device. All photos remain securely stored in a passphrase protected encrypted vault on your device. They are not uploaded to our or any other servers at any time. This is the ultimate privacy tool.

At Cacti, we value your identity, safety, and privacy. You don't have to sign up to use the service. There is no concept of an account. Just download and use the app. You are anonymous, so is your data. We firmly believe that your data belongs to you and no one else. We do not ever gain access to your private photos.

Simple and easy to navigate

Major standout for me was it eliminates the painful process of going through older pictures to put in the vault by running the algorithm, but at the same time gives an option to upload a recently taken picture using clipboard. Overall, a good application!
