Your email address, phone number and old accounts leave traces across the internet. Run a free digital footprint scan to see which known data breaches your email appears in — and what to do next.
TL;DR: Your digital footprint is everything about you that's visible or discoverable online — both what you posted yourself and what leaked, was listed, or was sold on without you noticing. You can check some of it yourself for free with Google and a breach database; an automated scan like Scan My Shadow covers far more ground in a few minutes.
Most people have never deliberately searched their own name, phone number, or email address the way a stranger might. When you do, the results can be surprising — old social profiles, forum posts, marketplace listings, or directories you forgot you were ever part of. Collectively, this is your digital footprint: the trail of information about you that's visible or discoverable online.
This page explains what that footprint is made of, what you can check yourself right now for free, and where an automated digital footprint checker like Scan My Shadow fits in — including what it does and does not claim to do.
Your digital footprint is the combination of information about you that exists online, whether you put it there yourself or someone else did. It's usually split into two kinds:
Information you knowingly shared — a LinkedIn profile, an Instagram account, a product review under your real name, a comment on a news article, a listing on OLX or Quikr.
Information collected or exposed without a deliberate post from you — your email or phone number appearing in a company's data breach, your details listed in a data broker's directory, or your number showing up because you once filled out a form that got shared or sold on.
Passive footprint is the part most people underestimate. You can control what you post, but you can't fully control what a service you signed up for years ago did with your information afterward.
These aren't abstract categories — here's what shows up when you run a digital footprint check in practice:
A digital footprint checker's job is finding these specific, individually forgettable things — not one big dramatic exposure, but the accumulation. That's what makes checking worthwhile even if nothing feels obviously "leaked."
The exact answer depends entirely on your own history online, but common categories include:
A phone number used once to sign up for a food delivery app in 2019 can end up associated with that number in a later breach of that company's database — long after the person stopped using the app.
Your phone number and email address are two pieces of contact information that many accounts, forms, and online services ask for. Because they can appear across different online sources, they can be useful starting points for checking your own digital exposure — in fact, a phone number alone can reveal more about you than most people expect.
Unlike your name, which many people share, a phone number or email is usually unique to you — so if either one turns up somewhere unexpected, it's a strong signal worth investigating. Much of how it gets there in the first place comes down to how data brokers collect and resell contact details.
This manual approach is genuinely useful and costs nothing — but it's also slow, and it only covers what you think to search for. It won't catch listings you don't know exist, breaches that weren't widely reported, or directory sites that don't rank on the first page of Google.
If you want a broader automated check, Scan My Shadow checks your phone number and email across 1,500+ sources and returns the findings in one plain-language report.
A digital footprint checker automates the search-and-compare process: instead of you manually Googling variations of your name, number, and email, the tool checks your details against a defined set of sources — breach databases, public directories, and indexed pages — and returns what it finds in one place. This is broadly the same idea behind OSINT (open-source intelligence) techniques used to piece together information about a person from what's already publicly available.
The value isn't magic; it's coverage and speed. A good checker can look through far more sources than a person reasonably would by hand, and it does so in minutes.
No tool, including ours, can search "the entire internet" or guarantee 100% accuracy. Coverage is always limited to the sources a tool actually checks, and results reflect what was publicly indexed at the time of the scan.
Scan My Shadow is a one-time, $9.99 scan focused specifically on your phone number and email — we don't scan photos, and we don't ask for any other personal identifiers. The scan is consent-first: you check your own details, not someone else's.
If your main concern is one specific identifier, you can also explore the dedicated phone number exposure check or email exposure check.
Not everything in a digital footprint check comes from a breach or a data broker — a meaningful part of it is simply what Google has already indexed and cached about you. Three specific mechanics explain why:
A quick manual check worth doing alongside any automated scan: search your own name in quotes on Google and watch what autocomplete offers as you type it — both surface index-level exposure that breach databases and data brokers don't touch.
Your report shows an overall exposure summary, followed by each specific finding — where it was found, and what kind of information it is (a breach record, a public listing, and so on). Where relevant, we include practical next steps, like requesting removal from a specific directory or changing a password tied to an old breached account.
If the scan finds nothing across the sources we check, you'll still get a report confirming that — it's a genuinely useful result, not an empty one.
We only ask for what the scan needs: your phone number and email. There's no account creation and no password required. The phone number and email you submit are used to run the scan and generate your report, then deleted from our systems immediately after — we don't keep a copy.
A one-time scan of your phone number and email across 1,500+ sources, with a plain-language report in about 5 minutes.
