Think about everything you've spent money on in the last month. Every meal, every impulse buy, every subscription renewal, every late-night Swiggy order. Your spending data is essentially a diary, except more honest than any diary you'd actually write.
Now ask yourself: who else should have access to that?
Your spending data is more revealing than you think
Most people worry about their passwords getting leaked, their photos being stolen, or their messages being read. But your transaction history? That paints a far more complete picture of your life than any of those.
Your spending shows where you go, what you eat, what medications you buy, which apps you subscribe to, whether you're saving or drowning. It reveals patterns you might not even be aware of yourself.
The problem with most expense trackers
Here's what typically happens when you install an expense tracker:
- It asks you to connect your email account
- It gets access to your entire inbox, not just bank statements
- It scans thousands of emails looking for transaction receipts and bank alerts
- It uploads everything to a server for "processing"
- Your financial profile now lives on someone else's computer
Think about what's in your inbox. Flight confirmations, medical bills, salary slips, insurance renewals, subscription receipts. These apps read through all of it just to parse a few bank statements. Even apps that claim to care about privacy still process your data on their servers. The data has left your device, and once it's out there, you have no control over what happens to it.
What "on-device" actually means
When I say Fence processes everything on-device, I mean it literally. Your bank messages are parsed by your iPhone's processor. The transactions are stored in your iPhone's local database. The charts, categories, and trends are all computed right there on the device.
There is no server to hack because there is no server. Your data doesn't travel anywhere because it doesn't need to.
This isn't a privacy "feature." It's the architecture. I couldn't access your data even if I wanted to, because I never had it in the first place.
Privacy isn't a premium add-on
Some apps treat privacy like a luxury. "Upgrade to Pro to delete your data from our servers." That's backwards. Your financial data is yours by default. You shouldn't have to pay to keep it that way.
Fence is built on a simple principle: the best way to protect data is to never collect it. There are no servers to maintain, no databases to secure, no breach notifications to send. Just an app that runs on your phone and stays out of your way.
What this means for you
When you use Fence, you get an expense tracker that works even on airplane mode. Your data stays on your device even when you delete the app (unless you choose to erase it). Nobody ever sees your spending. Not me, not advertisers, not data brokers.
Your spending tells your whole story. It should stay yours.
