Behind the Map: Why Local-First Architecture Protects Your Travel Data
Hello again from Where.App! Today, let's discuss the revolutionary privacy-first architecture we've implement, called Local-First (LoFi) and how we're in the bleeding edge of tech and privacy.
Your Travel Data Shouldn’t Be for Sale
Most apps today treat your location data as currency. Every step you take is shared, synced, stored, and resold. That’s not just creepy, it’s dangerous.
We built Where App differently. Behind the maps, Waylines, and guides is a Local-First (LoFi) architecture designed to protect your privacy while keeping everything fast and useful. Here’s why that matters.
The Problem With Cloud-First Everything
Most travel and mapping apps work like this: you move → they track → your data goes straight to the cloud.
That means:
Centralized risk: one breach, and everyone’s personal movement history is exposed.
Hidden monetization: data is sold to advertisers, quietly feeding someone else’s bottom line.
Lag and dependency: no connection? Your data disappears.
We decided that wasn’t acceptable.
What Local-First Actually Means
Local-first flips the model. With Where App:
Your movement is stored on your device first.
Sync happens only when you choose (and only the data you want to share).
Offline? No problem. Everything works, even without the internet.
It’s privacy-first, but it also makes the app faster and more resilient.
The Tech Stack That Makes It Possible
We didn’t just patch this together—it’s built into the DNA of Where App.
ElectricSQL + PGlite: sync and storage handled locally, with smooth coordination across devices.
TanStack DB: lets us query structured data quickly, right on your phone.
MCP + A2A for Wherebot: means the AI works with your data privately, instead of sending everything off to a server farm.
The result? You get modern AI-powered features without giving up control of your data.
Why Privacy Matters for Travelers & Creators
Travel is personal. Where you go says more about you than your Instagram feed ever could.
For travelers: no third party sees your exact routes unless you want them to.
For creators: your Waylines stay yours until you decide to publish or sell them.
For everyone: no ads, no creepy retargeting, no “always-on” tracking you can’t turn off.
The Future of Sharing on Your Terms
We also layered this into our five privacy modes—from Local to Sold—so you decide exactly how your data moves. Whether it’s a private journal of your morning run or a $500 Kathmandu trek Wayline, you’re in charge of who sees it.
Experience the World. Share it.
Local-first isn’t just a technical choice. It’s a philosophy: your movement belongs to you. Always.
Where App ensures you can experience the world, share it at your convenience, and keep it private when you prefer.
