Building a HIPAA-Compliant App? Here's What You Need to Know

If you’re building an application that touches patient data, there’s usually a moment when someone asks the question: “Are we HIPAA compliant?” Maybe it comes from a healthcare partner during procurement. Maybe it’s buried inside a security questionnaire that suddenly showed up in your inbox. Or maybe your legal team just discovered that your app now processes protected health information.

Either way, once that question gets asked, things tend to get serious quickly.

Because HIPAA compliance isn’t something you bolt on at the end of a sprint. It’s the baseline for building healthcare software. And if you get it wrong, the consequences go well beyond an awkward compliance conversation—think regulatory fines, lawsuits, and a level of reputational damage that’s very hard to undo.

The tricky part is that most developers, especially those on low-code or no-code platforms, don’t have a clear mental model of what HIPAA compliance entails. It’s easy to assume that picking the right hosting tier or seeing “HIPAA-ready” on a vendor’s pricing page means you’re covered. It doesn’t.

Compliance is a system-level concern. It touches your infrastructure, your application logic, your internal policies, and every third-party service that processes data in your stack. In this post, we’ll break down what HIPAA compliance actually means and why Xano is designed to support developers building in regulated environments.

HIPAA at a glance: the rules that matter

HIPAA was signed into law in 1996, but it's been updated significantly since then to keep pace with how healthcare data actually moves today. At its core, the law is built on a few key pillars that every healthtech builder should understand.

• The Privacy Rule defines what counts as Protected Health Information (PHI) and sets boundaries on how it can be used, shared, and accessed. If your app stores a patient's name alongside a diagnosis, a medication list, or even an appointment history, you're handling PHI.
• The Security Rule gets more specific. It requires administrative, physical, and technical safeguards for any PHI that's stored or transmitted electronically (known as ePHI). Think encryption, access controls, audit logs, and contingency plans.
• The Breach Notification Rule spells out what happens when things go wrong. If there's an unauthorized disclosure of PHI, the affected individuals, the Department of Health and Human Services, and in some cases the media must be notified.
• And the HITECH Act, passed in 2009, extended HIPAA's reach to business associates—meaning that if you're a software provider handling PHI on behalf of a healthcare organization, you're directly liable for violations too.

The rules are still evolving

HIPAA isn't static. Recent and proposed regulatory changes are raising the bar even further. Substance use disorder records, which were previously governed under separate rules, are now fully protected as PHI under HIPAA. Reproductive health information has been classified as specially protected PHI with additional restrictions on disclosure.

On the security side, a proposed overhaul to the HIPAA Security Rule would make multi-factor authentication mandatory, require organizations to maintain a technology asset inventory and network map, and introduce a 72-hour time limit for restoring systems after a cybersecurity incident. Annual compliance audits and encryption of all ePHI, both at rest and in transit, would also become explicit requirements.

Whether or not every proposal is finalized in its current form, the direction is clear: the compliance bar is going up, not down.

Compliance is a shared responsibility

Here's where most builders get tripped up. They sign up for a HIPAA-compliant tool and assume the job is done. But using a compliant platform does not make your application compliant. Compliance is a shared responsibility between your vendors and you.

Your platform provider is responsible for securing the underlying infrastructure including the data centers, the network layer, encryption of data at rest on physical storage, and the availability of the core services. That's the foundation.

But everything you build on top of that foundation is your responsibility. That includes how you authenticate users, how you design your API endpoints, how you enforce role-based access so that people only see the data they're authorized to see, how you handle session timeouts, and how you manage push notifications so they don't inadvertently display PHI on a locked screen.

Your responsibilities also include the organizational side: conducting your own risk assessments, training your team on PHI handling, writing and enforcing internal policies, managing the full data lifecycle (including secure deletion), and leading the incident response if a breach occurs within your application.

This shared model isn't a loophole or a limitation. It's how compliance actually works in practice, and understanding it early is the difference between building something that's genuinely secure and building something that just looks secure on paper.

What a HIPAA-compliant app actually needs

Before you write a single line of business logic, it helps to understand the categories of safeguards your app will need to address. You don't need to implement all of these on day one, but you need a plan for each.

• Encryption everywhere. Data must be encrypted both at rest and in transit. AES-256 is the standard for stored data, and TLS is the standard for data moving between your client and server. This applies to your database, your file storage, your API calls, and any third-party integrations.
• Role-based access control. Not every user should see every piece of data. HIPAA's Minimum Necessary Standard requires that you limit access to only the PHI that a given user needs to do their job. That means building granular permissions into your authentication and authorization logic.
• Audit logging. You need to be able to answer the question: who accessed what data, when, and why? Detailed audit trails are a core HIPAA requirement, and they're also your best friend during an investigation or compliance audit.
• Data segregation. PHI should be logically or physically separated from non-sensitive data in your database. This limits the blast radius if something goes wrong and makes it easier to apply targeted security controls.
• Session management. Inactive sessions should time out automatically. Users should be required to re-authenticate after a period of inactivity. This is especially important for mobile apps where a device might be shared or left unattended.
• Business Associate Agreements (BAAs). Every vendor in your stack that touches PHI—your backend, your hosting provider, your email service, your analytics tools—needs to have a signed BAA or BASA with you. No agreement, no PHI.
• Backup, recovery, and incident response. You need a tested plan for backing up your data, restoring it within a reasonable timeframe, and responding to security incidents with proper notifications. The proposed 72-hour restoration window in the new Security Rule gives you a sense of how seriously regulators take this.
• Secure development practices. Static and dynamic security testing, penetration testing by qualified third parties, and ongoing patch management are all part of building and maintaining a HIPAA-ready application.

How Xano fits this picture

Xano is a visual backend-as-a-service platform that gives you a database, API builder, and business logic layer, all without managing your own infrastructure. For healthtech builders, that's a significant head start because it means the infrastructure-level security is handled for you.

On the platform side, Xano provides encryption for data in transit and at rest, operates within physically secure data centers with environmental and access controls, and offers a HIPAA-compliant hosting plan with a Business Associate Agreement or Business Associate Subcontractor Agreement. Xano manages the security of the host operating systems, the virtualization layer, and the availability and recovery of the core platform.

On the application side, Xano gives you the tools to build what HIPAA requires of you: role-based authentication, custom API logic with authorization checks, environment separation between development, staging, and production, and request history logs that support your auditing strategy. You're responsible for using these tools correctly, but they're there and designed for this use case.
