Itemize: The Privacy-First Way to Split Expenses

We’ve all been there: the dinner bill arrives with 12 items, three shared appetizers, and a mix of people who had one drink versus three. Or worse, you’re back from a week-long road trip with a complex web of “who paid for what.” Typical expense-splitting apps force you to create accounts, hand over your email, and sync with their servers just to figure out who owes who twenty bucks.

Today, we’re changing that. Meet Itemize.

Itemize is a premium, client-side web application designed for one thing: making expense splitting as frictionless and precise as possible—without ever asking for your data.

🛡️ Privacy by Design: 100% Client-Side

#

We believe your financial habits are your business. That’s why Itemize is built with a True Serverless architecture:

• No Accounts Required: You don’t need to sign up, log in, or verify an email. Just open the app and start splitting.
• Static & Local: Itemize is deployed as a static site—meaning there is no backend server, no database, and no API collecting your data.
• Local Computation: Every calculation—from complex proportional tax distribution to group debt settlements—happens entirely on your device. Your data lives exclusively in your browser’s localStorage and never leaves your control.

⚡ Precision Splitting for Every Scenario

#

Whether it’s a simple lunch or a complex group holiday, Itemize handles the math so you don’t have to:

• Even Splits: The classic “divided by X” for quick settlements.
• Percentage Distributions: For when some people contribute more than others.
• Itemized Proportionality: Our most powerful feature. Assign specific items to specific people, and Itemize automatically distributes tax and tip proportionally based on each person’s subtotal. No more manual math for the service charge!

✈️ Travel Smarter with Trip Groups

#

Planning a long-term trip? Trip Groups allow you to bundle multiple expenses into a single workspace. At the end of the journey, our Minimum Transaction Algorithm (a greedy debt simplification engine) calculates the most efficient way to settle everyone’s balance. Instead of five different Venmos, you might only need one.

🔗 Seamless Portability

#

Even without a backend, Itemize makes sharing easy. You can generate a Compact Link that encodes your expense data directly into the URL. Send it to your friends, and they can “import” the entire expense state into their own local storage instantly. It’s the ultimate in data portability.
