Is My Financial Data Safe in This App? Seven Questions to Ask Before You Sign Up

A friend of ours put it better than any security page we had read. Before trying Networo, he asked one question: "Even if you never share my data with anyone, it still lives on your servers. What actually protects it?"

That is exactly the right question, and most finance apps answer it with a sentence that sounds reassuring and says nothing: "We use bank-level security to keep your data safe." Here are seven questions that get past that sentence. They work for any app you are thinking of trusting with your money, including ours.

1. Do I have to give you my bank login?

The safest bank connection is the one you never make. An app that works with numbers you type in yourself cannot leak your bank access, because it never had it.

If an app does connect to banks, the answer you want is that it uses an established connector (such as Plaid), that you log in on your bank's own screen, and that the app never sees or stores your bank username or password. You also want to know what it receives: balances only is very different from full transaction history.

How Networo answers: you never have to. Manual entry is the whole product. Bank sync is optional, off by default, runs through Plaid, and reads balances only, never transactions.

2. What exactly is encrypted, and where?

This is the question that separates real answers from marketing. "Encrypted at rest" often means the database provider encrypts its disks. That protects against someone walking off with a hard drive. It does not protect against someone who gets a copy of the database or its password, because the database happily decrypts for anyone who connects.

The stronger answer is that the app encrypts sensitive fields itself, before they are saved, with a key kept separately from the database. Then a stolen copy of the database is scrambled text.

A good app will also tell you what it does not encrypt, and why. An email address, for example, usually has to stay readable so you can sign in and receive reminders.

How Networo answers: every balance, account name, note, your income, expenses, goal and birth year are encrypted with AES-256 by Networo before they are saved. Your email, account categories and dates are not, and none of those contain an amount of money. The full list is on our security page.

3. Can you read my data?

Be wary of any app that says "no" without explaining how. For features like reminders, projections or an AI assistant to work, the server has to read your numbers, which means it holds a key.

"Zero-knowledge" apps, where only your device holds the key, do exist. They are genuinely private and genuinely limited: lose your password and your data is gone, and server-side features mostly cannot exist. Neither design is wrong. What matters is that the app tells you which one it is.

How Networo answers: our servers hold the key, because reminders, milestone emails, the AI Coach, household sharing and bank sync need it. That makes a stolen database unreadable, and it is not zero-knowledge, and we say so. Nobody at Networo browses your data.

4. Do you sell or share my data?

Look for a flat "no" and then look at how the company makes money. A free app with no paid tier has to be paid for somehow. Also check whether "we don't sell your data" quietly allows "sharing" with partners for marketing.

How Networo answers: we never sell, rent or share your data with advertisers or data brokers. We make money from subscriptions. The service providers that run the product are named in the privacy policy.

5. How is my account protected?

Ask whether the app stores passwords itself, whether it offers two-step verification, and whether you can see and sign out the devices signed in to your account. An app that keeps its own password database is carrying a risk it does not need to carry.

How Networo answers: Networo never stores passwords. Sign-in runs on Clerk, a dedicated identity provider, with protection against automated password guessing, and you can review signed-in devices from Settings.

6. What happens when I leave?

Two things matter here. First, can you take your data with you, for free, in a format you can actually use? Second, when you delete your account, is it deleted or merely hidden?

Specifically, you want: records erased immediately, any subscription cancelled so you are not charged again, bank access revoked at the provider, and a stated time after which backups expire.

How Networo answers: you can export every value you have ever recorded as a CSV at any time, free, in a format Networo can import again. Deleting your account erases your records immediately, cancels any Networo subscription first, revokes bank connections at Plaid, and backups expire within 7 days.

7. What happens if something goes wrong?

No honest company can promise a breach will never happen. What they can promise is what they will do: how fast they will tell you, what they will tell you, and how you can report a problem you find.

How Networo answers: if personal data is accessed without authorisation, we will tell the people affected without undue delay and within 72 hours of confirming it. Security reports go to the address on our security page, and we publish a standard security.txt file.

The phrases to distrust

A few words should make you look harder rather than relax:

1. "Military-grade" or "unhackable." Neither is a technical standard, and nothing is unhackable.
2. "Bank-level security" with no detail. Bank-level encryption is a real claim; bank-level security as a blanket statement is not.
3. "Your data is encrypted" with no mention of where, or of who holds the key.
4. A security page with no date on it. Security changes. A page that never changes is not being maintained.

A trustworthy app can answer all seven questions in plain language, including the uncomfortable parts. If an app will not, that is your answer.
