Security & Data

We built Catcher for people who ask "is it safe?"

The number one question we get. Here's the full, honest answer โ€” not marketing speak.

๐Ÿ”

Read-Only Access

Catcher can see transactions but can never move money, make payments, set up direct debits, or modify your account.

๐Ÿ›ก๏ธ

AES-256-GCM Encryption

Your data is encrypted at rest and in transit โ€” the same standard used by banks and governments. Access is restricted to Catcher systems only.

๐Ÿ‡ช๐Ÿ‡บ

EU Data Only

Your data never leaves the European Union. Processed under GDPR. Hosted on EU servers.

๐Ÿ›๏ธ

Regulated Provider

Bank connection via TrueLayer โ€” an FCA-authorised Account Information Service Provider operating under PSD2.

How Your Data Flows

1. You connect your bank. Catcher redirects you to your bank's own login page via our regulated Open Banking provider. We never see your username or password โ€” your bank authenticates you directly.

2. Catcher reads your transactions. Read-only. We receive transaction descriptions, amounts, and dates. We cannot see your full account number or initiate any payments.

3. AI classifies your spending. Transactions are categorised by our AI (large language model technology). Your data is pseudonymised before analysis โ€” no name, address, or account details are sent to the AI.

4. Letters are drafted for you. Negotiation letters are drafted using your transaction data. Sensitive personal information is never included unless you add it yourself before sending.

5. You're always in control. You review every letter before it's sent. You choose what to action. You can disconnect your bank and delete all data at any time โ€” one tap, everything gone.
