LGPD and data in marketing: what you need to know

The LGPD (General Data Protection Law) is the Brazilian legislation that regulates the processing of personal data, meaning information that identifies or can identify an individual. It establishes individuals' rights over their data and the duties of those who collect and use this data. The goal is to protect privacy and give people more control over their information. In marketing, which intensely uses data from customers and potential customers, the LGPD has a direct impact on how this data can be processed.

Beyond legal obligation, respecting privacy is a matter of trust and respect for individuals. Customers are increasingly aware of how their data is used, and distrust brands that handle their information carelessly. Handling data responsibly and transparently isn't just about complying with the law; it's about building a relationship of trust. Brands that respect privacy differentiate themselves positively, while those that abuse data risk their reputation and customer relationships, in addition to legal consequences.

The LGPD relies on principles that guide responsible data processing. Among them: having a legal basis to process data (such as the individual's consent, in many marketing cases), using data only for legitimate and informed purposes, collecting only what is necessary, being transparent about what is collected and why, ensuring data security, and respecting individuals' rights over their information. These principles form the basis of good data practices in marketing.

Two central concepts in marketing are consent and transparency. In many cases, using people's data for marketing requires their consent, obtained clearly and informatively. And transparency means making it clear to people what data is collected, for what purpose, and how it is used. This is reflected in practices such as clear privacy policies, explicit consent options, and the ability for individuals to manage their preferences. Consent and transparency are at the heart of responsible data processing.

The LGPD guarantees individuals rights over their data, such as knowing what data a company holds about them, correcting information, and requesting data deletion, among others. For marketing, this means having processes that allow these rights to be respected: for example, making it easy for people to unsubscribe from communications or request the removal of their data. Respecting these rights is not just an obligation; it's part of treating people with the respect they deserve regarding their information.

The best way to approach LGPD and privacy is as an integral part of a good data strategy, not as an obstacle. Marketing that respects privacy builds trust, protects itself legally, and treats customers with respect, which is good for the business in the long run. Incorporating data care from the outset, rather than treating it as a problem to circumvent, is the path to data-driven marketing that is both effective and responsible. Privacy and good results are not opposites. (This guide is informative and does not constitute legal advice; for specific situations, consult a specialized professional.)
