We're all about using website analytics to understand our audience better, but with that power comes responsibility, especially when it comes to personal information. You might have heard the term "PII" thrown around – that stands for Personally Identifiable Information, and it's any data that could be used to pinpoint a specific person. So, with Google Analytics 4 (GA4) being the new sheriff in town, it's natural to wonder: how does GA4 handle PII, and what can we do to make sure our data stays safe and compliant? In this post, we'll break down the need-to-know about PII in GA4 and guide you through some best practices to keep your data squeaky clean.
What is PII and why is it important?
PII refers to any data that could potentially identify an individual. It is also personal information that could potentially harm users; We're referring to any data that, if misused or mishandled, could lead to negative consequences for individuals. In GA4 and website analytics, this often includes sensitive details such as names, email addresses, phone numbers, or even IP addresses.
Imagine a scenario where a website inadvertently collects users' email addresses through a contact form or newsletter signup without their consent. If this information were to fall into the wrong hands or be exposed in a data breach, it could lead to spam, phishing attempts, or even identity theft, causing significant harm and distress to the affected individuals.
Protecting PII matters for two significant reasons:
- User Privacy: When personal information falls into the wrong hands, it can lead to identity theft, phishing attacks, and other privacy breaches. Safeguarding PII is crucial for maintaining user trust and security online.
- Legal Compliance: Laws and regulations like the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) mandate the protection of PII. Failure to comply with these regulations can result in hefty fines and damage to a company's reputation.
How does GA4 handle PII?
Google Analytics 4 prioritizes user privacy by default. It doesn't collect PII directly. Instead, it focuses on gathering anonymized data and assigning user IDs to track website behavior. This approach helps protect user privacy while still providing valuable insights to website owners.
Here's a breakdown of how GA4 handles user data:
- GA4 primarily collects anonymized data, which means that the information gathered from website visitors is stripped of any personal identifiers. For example, instead of recording a visitor's name or email address, GA4 might track their interactions with the website, such as page views or button clicks. This ensures that individual users remain anonymous within the analytics data.
- In addition to anonymized data, GA4 utilizes user IDs to track individual user sessions across multiple interactions with the website. However, these user IDs are not tied to any personally identifiable information. Instead, they are randomly generated identifiers that allow GA4 to analyze user behavior over time without compromising user privacy.
By focusing on anonymized data and user IDs, GA4 strikes a balance between providing valuable insights to website owners and safeguarding user privacy. Website owners can still gain valuable information about user behavior and engagement without collecting sensitive personal information. This approach aligns with modern privacy standards and regulations, ensuring that user data is handled responsibly and ethically.
Potential sources of PII that might leak into GA4 data
Even though GA4 doesn't gather PII by default, it's essential to be cautious as PII can inadvertently find its way into the data through various sources:
- Website Forms: If website forms collect personal information like names or email addresses, there's a risk of this data being transmitted to GA4.
- User IDs: While user IDs are meant to anonymize data, they can inadvertently reveal PII if they include identifiable information.
- Custom Dimensions: Custom dimensions are additional data points that can be sent to GA4. If not configured correctly, they might contain PII.
- Data Import might also be one of the other ways to expose personal data. That is why Google Analytics recommends reading the Upload data use policy before using Data Import or uploading data to Analytics.
Best practices for keeping PII out of GA4 data
To ensure PII remains protected and doesn't enter GA4 data, consider implementing the following practices:
- Configure data collection settings in GA4: This means setting up how data is gathered in Google Analytics 4 (GA4). One example of this is using a feature called data redaction, which helps to hide or remove sensitive information from the data being collected. However, it's important to note that this feature is only applicable to data collected from websites.
- Regularly review custom dimensions and user IDs to ensure they don't contain PII: Custom dimensions and user IDs are ways to organize and identify data in GA4. PII stands for Personally Identifiable Information, like names or email addresses. It's crucial to check these regularly to make sure they don't accidentally contain any personal information. If they do, it's necessary to change them to protect users' privacy.
- Take advantage of GA4's data filters to exclude any accidental PII: Sometimes, despite best efforts, personal information might be collected accidentally. GA4 provides tools called data filters, which allow you to sift through and remove any personal information that might have been collected mistakenly. This ensures that only relevant and anonymous data is used for analysis, maintaining user privacy.
- Make sure to read and understand policies pertaining to Data import: Data import is a feature in Google Analytics that allows you to bring external data into your analytics reports. It's essential to thoroughly read and understand the rules and guidelines regarding data import to ensure compliance with privacy regulations and to safeguard sensitive information from being mishandled or exposed.
Users Accidentally Collected PII Data
If you find that Personally Identifiable Information (PII) data has been inadvertently collected into your Google Analytics 4 (GA4) account, there are several methods you can use to address and prevent the issue and maintain compliance with privacy regulations. Here are some steps you can take:
- Remove any collected PII from GA4 immediately. This can be done through a request you can submit to the Google Analytics Support team through the so called Data-deletion request (DDR).
- Examine how PII is collected in GA4 by reviewing and auditing your data. Routinely check GA4 data and if there’s a need, adjust your settings to prevent future PII collection.
- Probably not the most common method, but you can also consider training team members on handling sensitive data properly.
- Always ensure compliance with GDPR, CCPA, and other regulations. Some methods, like implementing Consent Mode, are effective ways to prevent collecting PII data.

What if I need to collect some user data beyond anonymized website behavior for specific marketing campaigns?
If absolutely necessary, consider collecting specific user data only with explicit user consent and only for the defined campaign purpose. Ensure clear communication about data usage and provide an opt-out option.
How can I configure GA4 data collection settings to minimize PII risk?
Explore settings like IP anonymization, data retention periods, and disabling features that might capture unnecessary data.
How can I inform users about the data GA4 collects on my website?
Clearly display a privacy policy on your website that explains what data you collect, how it's used, and user options for control (e.g., opting out).
Does GA4 collect IP Addresses
No, Google Analytics 4 (GA4) does not collect or store individual IP addresses by default. This is a privacy-focused change compared to the previous version, Universal Analytics.
Final Words
When we talk about caring for user privacy, it's not just a matter of following legal regulations like GDPR or CCPA. It goes beyond that—it's about embracing a sense of responsibility and doing what's morally right in the digital community.
