Your Digital Footprint: What Information Exists About You Online

Every time you register to vote, buy a house, donate to a political campaign, or sign up for yet another website, you're leaving traces behind. All those traces add up to your digital footprint -- the total picture of data that exists about you online and in public record databases. And for most Americans, that picture is way more detailed than they think.

I run searches on myself periodically just to see what's out there, and every time I do, something new has shown up. An old address I forgot about. A donation from 2019. A property record update. It piles up fast.

What Exactly Is a Digital Footprint?

Your digital footprint breaks down into two categories, and the distinction matters:

Active digital footprint: This is the stuff you intentionally put out there. Social media posts, blog comments, online reviews, photos you upload, profiles you create. You have direct control over this category -- at least in theory.

Passive digital footprint: This is the stuff collected about you without your direct involvement. Browsing history tracked by cookies. Location data from your phone. Purchase records from retailers. Public records generated when you interact with government agencies. You have much less control here because this data gets created as a byproduct of just... living your life.

Here's the part that catches people off guard. Most people carefully curate their Instagram while being completely unaware that their voter registration, property tax records, campaign donations, and court filings are all freely searchable by anyone with an internet connection. The passive footprint is almost always bigger than the active one.

Types of Data in Your Digital Footprint

Public Government Records

Government agencies at every level maintain records that are, by law, available to the public. This includes:

• Voter registration records -- your name, address, date of birth, party affiliation, and voting history (whether you voted, not who you voted for) are public in most states
• Property records -- deed transfers, assessed values, tax amounts, and mortgage info maintained by county assessors and recorders. Our property records guide goes deeper on this
• Campaign finance records -- federal donations over $200 are disclosed with your name, address, occupation, and employer. See our campaign finance guide
• Court records -- civil and criminal case filings, including divorces, lawsuits, and traffic violations
• Business filings -- registered a business? Your name and address may be in Secretary of State databases
• Professional licenses -- doctors, lawyers, contractors, real estate agents, and many other professions have publicly searchable licenses

Frankly, the amount of government data that's publicly available surprises most people when they first see it all in one place.

Commercial Data

This is the murkier side. Private companies collect and trade massive amounts of personal data. Data brokers buy information from retailers, credit card companies, loyalty programs, app developers, and website operators, then compile it into consumer profiles with your purchasing habits, estimated income, interests, and lifestyle indicators. Unlike government records, commercial data isn't subject to the same transparency requirements. You often have no idea what's being sold about you or to whom.

Social Media and User-Generated Content

Your profiles, posts, photos, comments, and connections. A big chunk of your active footprint. Even content you've deleted may persist in cached versions, screenshots someone else took, or third-party archives. And here's a detail people miss: privacy settings change. Content you thought was locked down may have been publicly visible during a period when a platform quietly changed its defaults. (Facebook has done this multiple times.)

Website Tracking and Behavioral Data

Cookies, tracking pixels, browser fingerprinting -- websites use all of it to monitor what you do online. Which sites you visit, how long you stay, what you click, what you search for, what device you're on. Advertising networks aggregate this across thousands of sites to build behavioral profiles used for targeted ads. It's not exactly a secret, but the scale of it tends to unsettle people when they actually look into it.

How People Search Sites Put It All Together

People search services, including OpenDataUSA, work by compiling publicly available records and matching them to create unified profiles. Here's how the process works in broad strokes:

1. Data acquisition: Public records get collected from government databases at the federal, state, and county level -- voter files, property records, FEC donation records, business filings, court records where available.
2. Identity resolution: Records from different sources get matched to the same individual using combinations of name, address, date of birth, and other identifiers. This is harder than it sounds because people move, change names, and share common names with thousands of other people.
3. Profile creation: Matched records get combined into a single profile -- current and past addresses, approximate age, known relatives and associates, property ownership history, voter registration details, political donation history.
4. Search indexing: Profiles get indexed so users can search by name, city, state, or other criteria.

One thing worth clarifying: people search sites don't create new information about you. They aggregate and organize information that already exists in public records. The convenience factor is real, though -- instead of searching dozens of county assessor websites, state voter file databases, and federal campaign finance records individually, you find it all in one place. Our data sources page has specifics on the records we use.

How to Reduce Your Digital Footprint

Going completely invisible isn't realistic if you want to participate in modern society. But you can take meaningful steps to limit your exposure.

Audit Your Current Exposure

Start by searching for yourself. Use OpenDataUSA, Google your own name in quotes, and see what comes up on social media. This gives you a baseline. I recommend doing this at least once a year -- you might be surprised what's accumulated since you last checked.

Tighten Social Media Privacy Settings

Review privacy settings on every platform you use. Set profiles to friends-only or private where you can. Be aware that some things (like your Facebook profile photo and name) are always public no matter what. And if you have accounts on platforms you haven't touched in years, consider deleting them entirely. Dormant accounts are still data sitting out there.

Opt Out of People Search Sites

Most reputable people search services offer opt-out mechanisms. At OpenDataUSA, we provide a straightforward opt-out process. But keep in mind: opting out of one site doesn't remove your information from the underlying public records or from other aggregators. You may need to submit requests to multiple services. It's tedious, but it works.

Limit Data Sharing with Companies

Be selective about handing out personal information to businesses. Use a secondary email for online shopping and loyalty programs. Skip providing your phone number or date of birth when it's not actually required (most of the time, it isn't). In states with consumer privacy laws like the CCPA, you have the legal right to request that businesses delete your data and stop selling it. Use those rights.

Use Privacy-Enhancing Tools

Ad blockers and tracker blockers can significantly cut down on passive data collection. A VPN masks your IP address and location. Privacy-focused browsers and search engines exist as alternatives to the data-hungry defaults. Clearing your cookies regularly helps too. None of this makes you invisible, but it shrinks the flow of new data being collected about you.

Be Thoughtful About Public Records

Some states let you request that your voter registration address be kept confidential if you're a victim of domestic violence or stalking. If you're buying property and want to limit exposure, holding title through a trust or LLC is an option (though it has legal and tax implications -- talk to a lawyer first). Being aware of which actions generate public records helps you make informed choices.

Finding Your Balance

There's an inherent tension here between transparency and privacy. Public records exist for good reasons -- they prevent real estate fraud, hold politicians accountable, and let citizens participate meaningfully in governance. But the ability to aggregate all those records into searchable profiles creates privacy concerns that didn't exist a generation ago.

The goal isn't to erase your digital footprint entirely. That's neither practical nor, honestly, necessary. The goal is to be an informed participant. Know what information exists about you. Understand who can access it. Take steps to limit exposure where it matters to you. And use the tools available -- including our privacy policy and opt-out options -- to exercise the control you do have.
