Bank aggregator: what's it really for?

You have a current account here, a savings account there, maybe a card in a neobank and a joint account. The result: you never have an overall view of your money. That's exactly the problem a bank aggregator solves.

The simple definition

A bank aggregator is a tool that brings all your accounts — from all your banks — into one place. You connect your banks once, then you see all your money on a single screen, updated automatically.

No more opening five apps to know where you stand.

How it works, concretely

The connection relies on secure standards framed by European regulation (the famous PSD2). In practice:

• You choose your bank from the list
• You authenticate via your bank's secure system
• Your accounts appear, read-only

Read-only is the key point: an aggregator can see your transactions, but can never move your money. It reads, it doesn't touch.

What it changes day to day

• You see your total balance, across all accounts
• Your spending sorts itself automatically by category
• You spot subscriptions and recurring charges
• You track your savings without entering anything by hand

It's the difference between enduring your accounts and steering them.

The security question

That's the first concern, and it's a legitimate one. A good aggregator never stores your banking credentials, encrypts your data, and works read-only.

Trya goes further: your data is never sold, it's encrypted, and you can erase everything whenever you want. The sync covers thousands of banks across 31 countries — you connect, and you see everything, securely.
