Check out xkcd’s xkpasswd. It allows you to generate very secure passphrases with various configurations.

The reason we use the word passphrase and not password throughout the Cacti Vault app is because we want to push you to use as long a passphrase as possible.

  • The US National Institute of Standards and Technology (NIST) recommends creating long passphrases that are easy to remember and difficult to crack. According to Special Publication 800–63, Digital Identity Guidelines, a best practice is to generate passphrases of about 64 characters, including spaces. …

That’s a great question!

tl;dr: Your data would be safe and sound. You would still be able to access it with no difference for at least a year or two (This is only limited by when the iOS version stops supporting the last app update we would have released.)

The Cacti Vault is built to work right on your device. It does not require any backend or cloud system to work. The vault, the AI algorithm, your encrypted data — all stay right on your device. Once we release a version of the app on the App Store, our ability…

tl;dr — Lock your vault and unlock it to view these images.

In some situations, images will not load in the Vault. This is done intentionally, don’t fret. All you have to do is lock your vault and unlock it to view them.

The scenario

If your vault is unlocked and you add images to it through the Share Extension, these new images will not load in the Vault grid view. This is because the images were added from outside the main app. Since Cacti doesn’t store the passphrase, the newly added images cannot be decrypted in that unlocked session.

Just locking…

The Smart Manager on Cacti is your window into exploring and accessing your photos from various sources. Smart Manager would be the primary place from which you choose photos to add to your Vault. The Cacti App supports the following sources, and many more are in the works.


If Cacti has your permission to access your Photos Library, Cacti starts analyzing the library by running each photo through our proprietary on-device intelligence (Machine Learning Model) to identify only the images that may be considered intimate/personal.

The Suggestions section shows you these hand-picked intimate/personal images that you can quickly add to…

Cacti will remember your selections between app launches. You can always continue your adding-to-vault workflow later. Photos chosen from Suggestions, any of your albums or media albums would all show under Selected Photos View. Once you’ve chosen enough photos, you can quickly add them all to the vault.

Here are some points to keep in mind

  • Cacti would add all selected photos to the vault and finally show you an iOS alert that would ask your permission to delete these photos. …

Cacti Vault is quite secure. Of course, nothing is a 100% secure; smart people are constantly trying to break into secure systems. Given that, we believe Cacti is secure enough due of the following reasons.

Your data stays on your device: No Cloud

We do not have a cloud component or a remote server for Cacti that stores any of your information or data. This decision was deliberate, and this means that your photos or any other personally identifiable data never leaves your devices because of Cacti.

Encryption: 256-bit AES for your Photos

Even the photos stored inside the Cacti Vault are encrypted using the industry-standard 256-bit AES. The key used for this is…

Cacti’s Vault is primarily encrypted using your passphrase. Cacti offers an alternate way to unlock your vault using Face ID or Touch ID (Biometric Unlock) on iPhones.

This article aims to inform you on the risks and exposure of using Biometric Unlock to help you make an informed decision.

What happens under the hood?

If you enable Biometric Unlock for your vault, Cacti stores your passphrase in Keychain. Keychain is an encrypted storage offered by iOS, and anything stored inside the Keychain by the Cacti app is accessible only to the Cacti app.

Every time you want to unlock your vault, we would first authenticate…

Verizy as a service is extremely simple to integrate into your product but, how it works behind-the-scenes is quite elaborate. Every document that Verizy processes undergo multiple layers of processing with various Machine Learning models and Computer Vision techniques.

Our engineers and researchers are constantly working on improving our algorithms to push our accuracies and overall performance further up.

Since we run a humongous amount of operations on each incoming document and our customers use Verizy during on-boarding of their customers, our infrastructure has to be resilient to down-times and spikes in traffic. Let me explain how we have achieved…

And How To Overcome It

Iz: The state of being at Inbox Zero.

It all started when Mailbox was released for iOS. The app motivated me to keep my inbox empty, it had fluid swipes which let me rip through emails, pushing them off the inbox and ultimately reaching my inbox’s state of zen — The Iz, which eventually became my state of zen.

It worked very well, it made me happy. It brought about this sense of satisfaction in seeing an empty inbox, a sense of completeness, an accomplishment of being done with your tasks. …

I started using Apple Music from the first day of its release. It has been a constant companion.

Apple has revamped the Music app on iOS and iTunes a few times since launch. There was one major visual overhaul and many feature additions and bug fixes till date.

But, what I can’t get over is why the Apple Music filter option in search is on different sides on the iOS Music app and iTunes.
