LGPD at the veterinary clinic: how to handle owner data and medical records securely
When people talk about the LGPD (Law No. 13.709/2018, Brazil's General Data Protection Law), they usually picture banks, e-commerce sites and big tech companies. But the law applies to any organization that processes the personal data of individuals in Brazil — and that includes your veterinary clinic. Every time you register an owner, store a phone number to confirm an appointment, or keep a clinical history, you are processing personal data.
The good news: compliance does not require a legal department. It requires organization, common sense, and a few consistent practices. Let's get to the essentials.
What data your clinic collects
It helps to separate two types of information:
- Owner data (an individual): name, tax ID, phone, email, address, sometimes payment details. All of this is personal data and is protected by the LGPD.
- Medical records and animal information: the animal itself is not a "data subject" under the law, but the record is linked to an identifiable owner. Clinical history, exams, observed clinical signs, prescriptions — in practice, this set is part of processing the owner's personal data.
In other words: the patient's record is not "neutral" data. It connects to a person, and so it deserves the same care.
Legal bases: why you may process this data
The LGPD requires a legal basis for each processing activity. You don't need consent for everything — the law sets out other grounds that usually fit clinical routine:
- Performance of a contract: treating the animal, issuing prescriptions and keeping the history are part of the service the owner hired.
- Compliance with a legal/regulatory obligation: records that veterinary practice requires you to keep.
- Legitimate interest: for example, contacting an owner about a follow-up or a vaccine reminder — always proportionate and transparent.
- Consent: required for uses that fall outside the original purpose, such as marketing communications. Here consent must be free, informed, specific — and revocable.
The practical point: identify why you keep each piece of information. Marketing requires consent; clinical care usually does not.
Principles that guide everything
Three principles capture the spirit of the law and are easy to apply day to day:
- Purpose: collect data for a clear, legitimate reason. Don't keep it "because it might be useful someday."
- Minimization: ask only for what you need. A tax ID to issue a prescription makes sense; detailed financial data from someone who only booked a consultation does not.
- Security: protect what you keep against unauthorized access, loss or leaks.
The owner's rights (the data subject)
The owner has rights you must be able to honor, including:
- Confirmation and access: knowing what data you hold about them.
- Correction of incomplete or outdated data.
- Deletion of data, where appropriate and respecting legal retention obligations.
- Portability and information about who you share the data with.
In practice, this means having a simple way to locate, correct and, where applicable, delete an owner's records.
Best practices that fit your routine
Compliance becomes a habit when you adopt simple, constant measures:
- Clear communication: explain, in plain language, what data you collect and why. A short privacy notice already helps a lot.
- Consent for marketing: only send campaigns to those who opted in, and offer an easy way to opt out.
- Access control: each team member accesses only what they need. Avoid shared passwords and generic logins.
- Backup and continuity: loose paper records or a spreadsheet with no copy are a risk. Keep a reliable backup.
- Choice of vendors and software: when using systems that store owner data and medical records, prefer tools that handle this information securely — protected storage, access control, and clarity about how data is kept.
Extra care with digital and AI tools
Consultation transcription, structured records and digital prescriptions save time — but they process sensitive data. When adopting these tools, watch for:
- Where the data is stored and whether there is adequate protection.
- Who has access and how that is controlled.
- Vendor transparency about how information is used.
- Purpose: data should serve the care you provide, not parallel uses without authorization.
Using AI is not incompatible with the LGPD — as long as the tool is chosen carefully and keeps data protected.
Conclusion
The LGPD is not an obstacle to good veterinary medicine — it formalizes what responsible clinics already do: caring for information with the same diligence they care for patients. Start with the basics: know what data you collect, why you keep it, who accesses it, and how you protect it. Add tools that store data securely, and compliance stops being a burden and becomes a natural part of the routine — and a sign of respect for every owner who trusts you with their animal.
