How to Know If Your Financial App Protects Your Data Properly
By Monthly Dash Editorial Team ·
Before you link your bank account to any app, you should know whether your data is actually protected. Here is how to check, in plain language.
Linking a financial app to your bank account feels convenient right up until you wonder whether your account numbers, balances, and transaction history are actually safe. That concern is reasonable, and the good news is that you do not need a computer science degree to find the answers. You just need to know where to look and what to look for.
## Why Encryption Matters for Financial Apps
Financial apps often hold a remarkable amount of sensitive information: bank account numbers, credit card details, bill payment history, net worth estimates, and sometimes even Social Security numbers. If that data is stored or transmitted without proper encryption, a breach could expose everything to someone who has no business seeing it.
Encryption scrambles your data into unreadable code. Without the correct decryption key, the information is useless to an attacker. Two types of encryption matter most for any app that handles your money.
### Encryption at Rest
This protects data while it sits on a server. Imagine your checking account balance, say $4,200, is stored in a database. Encryption at rest means that even if a bad actor gained access to that database, they would see garbled nonsense instead of your real numbers.
The standard to look for is AES-256 (Advanced Encryption Standard with a 256-bit key). It is widely used by banks, government agencies, and reputable technology companies. If a financial app's security documentation mentions AES-256, that is a strong signal they are taking storage security seriously.
### Encryption in Transit
This protects data while it is moving between your phone or browser and the app's servers. Every time you open the app and your transactions load, data travels across the internet. Without encryption in transit, someone on the same network could potentially intercept that transfer.
The protocol to look for here is TLS, or Transport Layer Security. Specifically, TLS 1.2 or TLS 1.3 are the current acceptable standards. An older protocol called SSL is largely outdated and considered insecure, so any app still referencing SSL only (without TLS) is worth scrutinizing.
A quick way to check this yourself: open the app's web version in a browser and look for a padlock icon in the address bar. That padlock indicates an active TLS connection. It is a basic check, not a guarantee of full security, but it is a useful first step.
## Where to Find Security Information
Most reputable financial apps publish their security practices, but you sometimes have to dig for them. Here are the most useful places to look.
- The security or privacy page on the company's website, often linked in the footer
- The app's privacy policy, which by law must describe how your data is handled (requirements vary by country and region)
- A dedicated trust or compliance page, sometimes called a "Trust Center"
- Third-party security certifications, such as SOC 2 Type II reports
### What Is SOC 2 Type II?
SOC 2 (System and Organization Controls 2) is an audit framework developed by the American Institute of Certified Public Accountants. A Type II report means an independent auditor has reviewed the company's security controls over a period of time, typically six to twelve months, and verified they actually work as claimed. It is not a guarantee of perfect security, but it is a meaningful signal that a company takes security seriously enough to be externally reviewed.
If an app has completed a SOC 2 Type II audit, that information is usually displayed prominently. If you cannot find it, you can email the company's support team and ask directly.
## A Comparison of What to Look For
The table below summarizes the key signals to evaluate when assessing a financial app's security posture.
| Security Feature | What to Look For | Red Flag |
|---|---|---|
| Data at rest | AES-256 encryption mentioned | No encryption standard named |
| Data in transit | TLS 1.2 or TLS 1.3 | SSL only, or no mention at all |
| Third-party audit | SOC 2 Type II report | No external audits disclosed |
| Authentication | Two-factor or multi-factor auth | Password-only login |
| Data sharing | Clear opt-out for third-party sharing | Vague or missing data sharing policy |
| Breach notification | Committed policy for notifying users | No breach policy mentioned |
## Two-Factor Authentication Is Non-Negotiable
Even with strong encryption in place, a leaked password can undo everything. Two-factor authentication (2FA) adds a second layer: typically a code sent to your phone or generated by an authenticator app. If a financial app does not offer 2FA, that is a significant gap in their security design.
If you connect a financial app to accounts holding real money, for instance a brokerage account with $18,000 in it, enabling 2FA should be one of the first things you do. Check the app's settings under Security or Account.
## How to Ask the Right Questions
If you cannot find clear security documentation, contact the company before connecting any accounts. Here are specific questions worth asking.
- Do you encrypt data at rest with AES-256?
- Do you use TLS 1.2 or 1.3 for all data in transit?
- Have you completed a SOC 2 Type II audit, and can I see the report or a summary?
- How do you handle a data breach, and how will you notify users?
- Do you sell or share my financial data with third parties?
A company that cannot or will not answer these questions clearly is telling you something important.
## Reading the Privacy Policy Without Falling Asleep
Privacy policies are long for a reason, but a few targeted searches can save time. Open the policy and use your browser's find function to search for the words "encrypt," "TLS," "AES," "third party," and "sell." What you find, or do not find, will tell you a lot in under five minutes.
Pay special attention to how the company describes data sharing with partners and advertisers. Some free financial apps offset their costs by sharing anonymized, or sometimes not-so-anonymized, transaction data. If your $3,800 monthly grocery and restaurant spending is being analyzed and sold, you deserve to know that upfront.
## Putting It Together Before You Connect
Apps like [Monthly Dash](https://monthlydash.com/), which turn your transactions, recurring bills, and assets into a searchable personal finance narrative, handle genuinely sensitive data. Knowing that your net worth history, bill payment records, and AI-assisted financial analysis are protected by modern encryption standards is not optional knowledge. It is basic due diligence.
Before linking any account, spend fifteen minutes with the steps above. Check the security page, look for AES-256 and TLS 1.3, search for SOC 2 Type II, and enable two-factor authentication the moment you sign up. These small steps cost very little time and can save an enormous amount of trouble.
Your financial data is a detailed map of your life. It deserves the same care you would give to any other valuable thing you own.
Questions That Matter
How can I tell if a financial app encrypts my data?
Look for mentions of AES-256 encryption for data at rest and TLS 1.2 or higher for data in transit in the app's security or privacy documentation. Reputable apps also publish SOC 2 compliance reports and offer two-factor authentication. If none of this information is easy to find, treat that as a warning sign.
What is the difference between encryption at rest and encryption in transit?
Encryption at rest protects your data while it is stored on a server, so that even if someone breaks in, they cannot read your files. Encryption in transit protects your data as it travels between your device and the app's servers, preventing interception along the way. You need both for meaningful protection.
