Cloud vs local: what changes for patient privacy

Almost every new practice management product is sold as cloud software. The pitch is appealing: nothing to install, automatic off-site backups, and access from any device. For a lot of clinics that is a reasonable choice. But it is worth understanding precisely what changes when your patients' records move from a computer in your office to a server somewhere else.

This is not an argument that the cloud is bad. It is a look at the tradeoff, so you can decide what is right for your practice.

What 'in the cloud' actually means

When a product is cloud-based, your patient records are stored in the vendor's data centers, usually in a shared database that holds many clinics' data at once. You reach your records through a browser, and the vendor's systems sit between you and your own data at every step.

That arrangement is what makes the convenient parts possible. It is also what creates the tradeoff, because your access and your privacy now depend on decisions made by someone else.

Who can reach the data

With cloud storage, the set of parties who can technically reach your patient data is larger than just your clinic:

• The vendor operates the servers and, in practice, can access the data to run and support the service.
• Their subprocessors, such as the hosting provider, are part of the chain that stores or moves the data.
• Anyone who breaches the vendor reaches a single store holding many clinics at once, which is a bigger target than one office.

What you depend on

Beyond privacy, cloud storage ties your daily work to things outside your control: your internet connection, the vendor's uptime, and the vendor's continued existence and pricing. If any of those fails, your access to your own patients' history can pause with it. A subscription that scales with your patient count adds a cost that grows quietly over time.

None of this is hypothetical or rare; it is simply the nature of renting space for your data on infrastructure you do not own.

How local-first changes the picture

Local-first software inverts the model. The app and the data live on your own computers, and the vendor is kept out of the path of the patient data. With HM Praxis specifically:

• Records are stored on your machines, in a local database, not in a shared multi-tenant cloud.
• The database is encrypted at rest with SQLCipher, so a lost laptop does not mean exposed records.
• Team sync is local-network only on the Pro plan, so patient data never crosses a server we run.
• Our servers only see your account, license, and billing, never a patient chart.

If you want the technical detail of how the encryption and recovery work, the data custody guide walks through it.

Which should you choose?

If unreliable internet, a sensitive patient base, or simply the principle of owning your records weighs on you, local-first is worth a serious look. If you value access from anywhere above keeping the data in-house, cloud may suit you better. The point is to choose deliberately rather than by default.

If local-first sounds right, our comparison of cloud versus a local alternative lays out the differences point by point.
