In this digital age, private browsing using Chrome's Incognito Mode, Safari's Private Browsing, Firefox's Private Window and others is quite common. And most people assume that this type of browsing creates a digital shield that keeps their online activity secret.
That perception is understandable because tech companies market these features as ways to protect your privacy. However, the legal reality is very different. When you're involved in a criminal investigation or case in Michigan, you quickly realize the privacy you thought you had doesn't really exist.
Many people ask, “Can Incognito Mode be tracked?” The answer is yes. Private browsing settings do not prevent law enforcement, prosecutors, or courts from accessing your data. And when these parties use a proper legal process, they can obtain a full history of your online activity. This includes your browsing history, contents, and metadata.
Mark Linton, a highly respected Michigan appellate attorney, has represented clients in numerous cases involving digital evidence. And in this article, he explains why private browsing won't protect you in court and what the law regarding online activity says in Michigan. He also shares what you should know and do when your digital footprint is at issue in a criminal case.
What “Incognito" or “Private" Mode Really Means
Private browsing does various things. It prevents your web browser from storing your history locally on your device. It may also delete cookies and caches when your browsing session ends. And it gives a cleaner experience on that device.
Some people believe it hides your activity from your Internet Service Provider (ISP) and blocks the records kept by websites or apps you visit. Others believe that it prevents law enforcement from obtaining your digital data with a warrant.
Some even believe that it can actually stop Network Administrators at a workplace or school from seeing what you're doing on their network. The truth, however, is that a browser may not show a history of the sites you visited. But servers, service providers, and communications networks still have records.
And relevant authorities can still access those records.
Digital Evidence is Discoverable
Michigan law, specifically Michigan Court Rules (MCR) 6.201(K), treats electronic evidence as any other documentary evidence. And courts recognize that digital records, including internet history, emails, and timestamps, are central to many investigations.
MCR 6.201 governs discovery in criminal cases. It allows the defense to request and the prosecution to disclose documents and tangible things that are material to preparing a defense. And these include digital records such as browser logs, server logs, IP records, and stored communications.
MCR 6.201(A)(6) specifically requires the prosecution to disclose any tangible item that it intends to offer at trial. And MCR 6.201(K) covers electronically stored information (ESI) when relevant. This means that even if you used Incognito Mode, digital service providers may still have preserved records.
And the providers must disclose the records if they're material. In Michigan, discovery under MCR 6.201 is mandatory upon request. This means that once a party asks for it, the other party must provide it. They don't necessarily need a specific court order for every single log once the process begins.
Can Incognito Mode Be Tracked Through Warrants and Subpoenas?
Law enforcement must usually use a warrant or subpoena to obtain digital records. The United States Constitution and the Michigan Constitution protect against unreasonable searches and seizures. Law enforcement must show probable cause to a judge before obtaining a search warrant for digital information.
Michigan Compiled Laws (MCL) 780.651 states that a warrant may be issued when there's probable cause. And this probable cause should lead the law enforcement to believe that the property or things to be seized will constitute evidence of a crime. This includes internet browsing records, stored communications, and cloud-based backups.
Even if you use private browsing, the data may be stored on remote servers beyond your device. And a warrant can require service providers to turn over that data. For certain records, like subscriber information or less content-specific data, law enforcement may use a subpoena.
Federal law, like the Stored Communications Act and Michigan practice, makes it clear. Subpoenas can compel an ISP or tech company to produce non-content records like IP logs without a full warrant. This depends on the type of data in question. However, private content generally requires a Probable Cause Warrant.

How Internet Activity Still Leaves a Trail
Even when users believe their activity disappears after closing a browser window, Incognito Mode can still be tracked through server logs, IP records, metadata, and provider records obtained through legal process.
Most internet activity leaves some forms of persistent digital records, whether or not you used private browsing. And these records include:
Service-level connection records - Major internet carriers such as Comcast and AT&T keep detailed histories. This includes which IP addresses were signed to which customer accounts, DNS requests, and connection timestamps. And these can link you to online activity without browser history.
Website and app servers - Websites and apps record login timestamps, IP addresses used, and specific actions like posts, messages, and uploads. And once the court issues a warrant or subpoena, these servers must comply.
Network logs - Corporate networks, school networks, and public WI-FI often record traffic that can be extracted with the right legal process.
Case Law Showing Incognito Mode Won't Save You
Can Incognito Mode Be Tracked by Police and Prosecutors?
People v. Woodard 321 Mich App 377 (2017)
Michigan courts and federal courts have clarified the standards for accessing digital records. And they emphasize that a user's attempt at privacy does not override legal discovery. In cases like the People v. Woodard (2017), Michigan courts have addressed the scope of digital searches.
And they've reinforced that users have a privacy interest in their devices. But that interest is subject to the state's power to seize evidence under a valid warrant. The court recognized that data is a tangible thing. And investigators may extract records even if they are not immediately visible on the device's interface.
MCR 6.201(K) also explicitly treats electronically stored information as discoverable evidence. The law focuses on the existence of the data rather than the mode used to browse. This, therefore, means that Incognito settings do not create a legal privilege that prevents the prosecution or defense from obtaining logs held by third-party service providers.
Digital evidence, including metadata, IP logs, and server-side records, remains discoverable under Michigan law. And this is despite the user having cleared their local browser history or utilizing private browsing modes to hide activity from other people using their device.
United States v. Warshak 631 F.3d 266 (6th Cir. 2010)
Warshak is a federal case but is highly influential in Michigan practice. The Sixth Circuit (which includes Michigan) held that a person has a legitimate expectation of privacy in the contents of their emails. But crucially, law enforcement must still obtain a valid warrant before accessing those records.
This case shows that digital privacy exists in theory. But in practice, warrants allow access when properly authorized.
People v. Carpenter, 138 S. Ct. 2206 (2018)
In this case, the U. S. Supreme Court ruled that accessing historical cell-site location information requires a warrant. This case does not directly address browsing history, but it reflects the fact that privacy protections exist.
However, they cannot be used as blanket shields in criminal cases. Law enforcement must follow constitutional procedure. And once they do, your digital footprints are fair game.
Incognito Mode is Not Encryption
One common misconception is that Incognito browsing encrypts or hides your activity. It doesn't. Your data still flows through your ISP, and it's still visible to servers. It's also stored in transient caches and logs.
Private browsing only affects your device's local history. That's why incognito is visible to law enforcement. Encryption, such as HTTPS, protects data in transit. But it does not hide the sites you visited in a way that makes them unreachable by legal process.
Meta Data and Attribution
A browser may not save your history, but certain forms of metadata can still identify you. These forms include timestamp of activity, IP addresses, login tokens and sessions, device identifiers, and geolocation.
And law enforcement can use this metadata to link you to a specific device. They can also use it to correlate activity across devices and build timelines of behavior. In Michigan practice, this kind of evidence is increasingly common in drug cases that involve digital communications about deals.
It's also prevalent in sex cases that involve online contacts, fraud that involves transaction histories, and threat cases where messages and posts are involved.
So What Should You Do When Your Case Involves Digital Evidence?
If you're wondering whether Incognito Mode can be tracked in a criminal case involving your online activity, it's important to understand how Michigan courts treat digital evidence and electronic records. Digital privacy is an evolving field, but current law treats digital records similarly to physical evidence. And proper legal standards must be met.
Another strategic move you should make is to seek experienced legal counsel early. A good Michigan criminal appeals attorney will meticulously analyze the legality of warrants and subpoenas. And they'll file suppression motions when appropriate.
They can also evaluate prosecutorial compliance with discovery as per MCR 6.201 and prepare appellate issues if the evidence was improperly admitted.
How Mark Linton Excels in Digital Evidence Cases
Mark Linton is a seasoned Michigan appeals lawyer who has mastered how to interpret and challenge digital records. He understands that while digital evidence can be obtained, there are limits. And he knows how to spot appealable issues such as lack of a valid warrant, overbroad warrants, and improperly authenticated data.
There are times when law enforcement obtains your digital data without a warrant when one was required. In such cases, Mark files a motion to suppress under MCR 6.110(D)(2) and the Exclusionary Rule as per the Mapp v. Ohio (1961) case.
Sometimes, warrants are too broad with vague descriptions of data or with the intent of fishing expeditions. And this is wrong because warrants must be sufficiently specific. In such cases, Mark challenges the broadness using Michigan precedent like the People v. Hughes (2020) case.
Michigan evidence law also requires digital data to be authenticated before it's admitted at trial. The Mitchell v. Kalamazoo Anesthesiology (2017) case clarifies that the judge decides authentication (is it what you say it is?). And the jury decides reliability (is it true?). And this requires showing a reliable connection between the evidence and the defendant's conduct.
Mark Linton analyzes whether the forensic methods used in your case were sound. He also evaluates whether the chain of custody was maintained. And he assesses whether the data presented actually reflects what the prosecution claims.
