The Loyalty Program That Might Be Illegally Selling Your Purchase History
Many loyalty programs collect 100% of your purchase history tied to your account and may share or sell it to data brokers or advertisers. Depending on your state, this can trigger disclosure, opt-out, and deletion rights under laws like CCPA/CPRA or other privacy statutes. This article explains how the data flows, what may be illegal, and what consumers can do.
What Loyalty Programs Are Really Doing With Your Data
You scan your loyalty card at the checkout, collect your points, and walk away thinking you got a good deal. But behind the scenes, something else might be happening. That simple scan could be feeding your purchase history into a system that sells that information to third parties — and in some cases, this practice may be crossing legal lines.
Loyalty programs have become one of the most powerful tools companies use to collect consumer data. Millions of people sign up for them every year, attracted by discounts and rewards. What many people don’t realize is that their shopping habits, personal preferences, and even health-related purchases can become valuable commodities traded between businesses without their full knowledge or consent.
How Your Purchase History Becomes a Product
When you join a loyalty program, you usually agree to a terms and conditions document that most people never read. Hidden in that legal language is often permission for the company to share or sell your data. Here is how the process typically works:
- Data collection: Every purchase you make is recorded and linked to your profile, including what you bought, when you bought it, how much you spent, and how often you shop.
- Data aggregation: This information is combined with other details you provided when signing up, such as your name, address, age, and email address.
- Data selling: The compiled profile is then sold or licensed to data brokers, advertisers, insurance companies, financial institutions, and other businesses looking for detailed consumer insights.
- Targeted use: Buyers use this data to target you with ads, assess your creditworthiness, adjust pricing, or even evaluate insurance risk.
The companies profiting from this process are not small operations. Data selling has become a multi-billion dollar industry, and loyalty programs are one of its primary feeding grounds.
When Data Selling Crosses Into Illegal Territory
Not all data sharing is illegal. But consumer rights advocates and legal experts are raising serious concerns about practices that may violate existing privacy laws. Here are some of the key issues:
Lack of Informed Consent
Privacy law in many regions requires that consumers give meaningful, informed consent before their personal data is sold to third parties. Burying this permission in dense legal text that the average person cannot easily understand may not meet the standard of “informed” consent. Several lawsuits have been filed in recent years challenging whether loyalty program agreements truly satisfy consent requirements.
Sensitive Purchase Categories
Some purchases carry more risk than others when exposed. Items bought at pharmacies, health food stores, or clinics can reveal medical conditions. Purchases at certain retailers can indicate religious beliefs, political leanings, or family situations. In many jurisdictions, the sale of data tied to sensitive categories like health information is subject to stricter rules — and companies that ignore these rules may be acting illegally.
State and National Privacy Laws
Consumer privacy protections vary widely, but they are growing stronger. Laws like the California Consumer Privacy Act (CCPA), the General Data Protection Regulation (GDPR) in Europe, and other emerging state-level laws in the United States are placing new limits on how companies can use and sell consumer data. Companies that have not updated their loyalty program practices to match these newer laws could be in violation right now.
Real-World Examples of Concern
Several high-profile cases have brought this issue into the public spotlight. Pharmacy chains in the United States have faced scrutiny for sharing prescription and purchase data with parent companies and third-party partners. Grocery chains have been investigated for selling purchase data to health and insurance companies. In some cases, regulators found that consumers were not properly informed and that the data sold included information that qualified for special legal protections.
These are not isolated incidents. As data selling has grown into a standard business practice, the number of companies operating in legally questionable territory has grown along with it.
What the Law Says About Your Rights
Depending on where you live, you may have stronger consumer rights than you think. Here is a general overview of what many privacy laws allow you to do:
- Right to know: You can request information about what data a company has collected about you and who they have shared it with.
- Right to delete: In many regions, you can ask a company to delete your personal data from their systems.
- Right to opt out: Many privacy laws give you the right to opt out of having your data sold to third parties.
- Right to correct: If data held about you is inaccurate, you may have the legal right to have it corrected.
- Right to sue: In some jurisdictions, if a company violates your privacy rights, you can take legal action and potentially receive compensation.
The challenge is that exercising these rights often requires knowing they exist in the first place — and that is exactly what many companies are counting on you not to know.
How to Protect Yourself
You do not have to give up loyalty programs entirely, but there are smart steps you can take to protect your personal information while still enjoying the benefits.
Read the Privacy Policy Before You Sign Up
It sounds tedious, but even skimming a loyalty program’s privacy policy can reveal whether the company sells your data and to whom. Look specifically for phrases like “share with partners,” “third-party marketing,” or “data licensing.” These are signals that your information may be going further than you realize.
Use a Separate Email Address
Create a dedicated email address for loyalty programs. This limits the amount of personal information tied to your main identity and makes it easier to manage marketing messages.
Opt Out Wherever Possible
Many programs now offer opt-out options for data sharing, sometimes buried in account settings. Take the time to find and use these settings. If a company operates in a jurisdiction covered by strong privacy laws, they are required to honor your opt-out request.
Limit What You Share
When signing up, only provide the information that is absolutely required. Avoid filling in optional fields like your birth date, phone number, or household income if the program doesn’t require them.
Review Your Rights Regularly
Privacy laws are changing quickly. What was not possible two years ago may now be your legal right. Check official consumer protection websites for your region to stay informed about your current rights.
What Needs to Change at the Industry Level
Individual action is important, but systemic change is also needed. Consumer rights advocates are calling for several reforms in how loyalty programs operate:
- Clear, plain-language disclosure that data will be sold and to what types of buyers
- Mandatory opt-in consent rather than opt-out defaults for data selling
- Stronger penalties for companies that sell sensitive data without proper authorization
- Independent audits of loyalty program data practices
- A universal national privacy law in the United States that sets a consistent standard across all states
Without these changes, the burden continues to fall on individual consumers to protect themselves against practices that are sometimes deliberately designed to be confusing.
The Bottom Line
Loyalty programs offer real value, and most people will continue to use them. But there is a growing body of evidence suggesting that some of these programs are using your purchase history in ways that go beyond what most people would consider fair — and in some cases, beyond what the law allows.
Understanding how data selling works, knowing your rights under privacy law, and taking simple steps to limit your exposure can make a real difference. The more consumers push back, ask questions, and demand accountability, the more pressure companies will face to operate transparently and within the boundaries of the law.
Your shopping history is about you. You deserve to have a real say in where it goes.
