Emma Vault

for Emma Vault

The website and subscription flow for an encrypted, on-device vault for photos and documents.

The problem

Emma Vault's app keeps files encrypted on the phone, never on a server. That is hard to explain in a sentence, and the old site did not try. Visitors needed to understand the promise and pick a plan before going to the app stores.

What we built

A React site that walks through the app one action at a time: lock down, add, search, transfer, share, wipe. Light and dark themes, three subscription plans with Stripe checkout, a privacy policy written for the zero-knowledge model, and links straight to the App Store and Google Play.

What happened

Live at emmavault.net, delivered after a round of client changes.
