How to do research without being tracked — a practical guide for journalists, researchers, lawyers, and privacy-conscious individuals who need to gather information on sensitive topics without creating a digital trail that links them to their research subjects.
When a person conducts research using standard tools — a personal web browser, a home or office internet connection, logged-in accounts — they create a persistent digital record of their research activity. This record exists in multiple systems and is accessible to multiple parties:
The browser: Browsing history, bookmarks, saved passwords, and autofill data. Accessible to anyone with physical access to the device or remote access to the account.
The internet service provider (ISP): The ISP sees all DNS queries (the domain names the user looks up) and the IP addresses of sites visited, even when HTTPS is used. ISPs in many jurisdictions can sell browsing history or are required to retain it and produce it on legal request.
Search engines: Search queries are logged against the user's account (if logged in) or against their IP address (if not). Search engines build behavioral profiles from query history. In the US, search history has been subpoenaed in criminal investigations.
Websites visited: Every site a user visits can log their IP address, user agent, referrer, and other metadata. Third-party trackers (analytics services, ad networks) on most websites build cross-site profiles of the user's browsing.
Account-linked activity: Any research done while logged into a Google, Apple, Microsoft, or similar account is associated with that account. Google's "My Activity" log records search queries, videos watched, map searches, and site visits when Chrome sync is enabled.
For most research, this tracking is an inconvenience with no practical consequences. For research involving sensitive subjects — an investigative journalist researching a powerful institution, a lawyer researching an opposing party, a researcher investigating a topic that could attract attention from the subjects of the investigation — the digital trail creates risks: it can be obtained through legal process, it can be obtained through data breaches, and in some jurisdictions it can be obtained by the subjects of the investigation through surveillance capabilities.
Untracked research eliminates or reduces this trail by choosing tools and practices that create minimal linkable records.
Untracked research is achieved by addressing tracking at multiple layers simultaneously. Addressing only one layer while ignoring others produces incomplete protection.
Layer 1: Network-level tracking (who can see your IP address)
Your IP address identifies your approximate location and (when combined with ISP records) your identity. Sites you visit see your IP address; your ISP sees the domains you visit.
Reduction strategies:
Layer 2: Browser-level tracking (cookies, fingerprinting, logged-in accounts)
Browsers accumulate tracking data through cookies, browser fingerprinting (the combination of screen size, fonts, browser configuration, and other attributes that uniquely identifies a browser), and logged-in account associations.
Reduction strategies:
privacy.resistFingerprinting option, substantially reduces browser-level tracking. Not as comprehensive as Tor Browser but more convenient.Layer 3: Search engine tracking (queries logged against identity)
Search queries are often the most sensitive part of research — they reveal what the researcher is looking for before any sites are visited.
Reduction strategies:
Layer 4: Account-linked activity (Google, Apple, Microsoft logged-in services)
Research done while logged into major platform accounts is associated with those accounts, regardless of other measures.
Reduction strategies:
Layer 5: The research notes and captures (where captured content goes)
Where research findings are saved creates a separate tracking exposure. Notes saved to iCloud Notes, Google Keep, or Notion are on third-party servers.
Reduction strategies:
Minimum baseline (significantly reduces common tracking):
Strong (addresses most realistic threat models for sensitive research):
Maximum (for high-sensitivity research: investigative journalism, legal defense, whistleblower assistance):
Before starting a research session:
During the session:
After the session:
Device-level malware: If the research device is compromised by surveillance software (spyware, stalkerware), all activity is visible to the attacker regardless of browser-level or network-level privacy measures. Device security (software updates, no untrusted software installed, strong passwords/biometrics) is foundational.
Social engineering: The most effective surveillance doesn't require network access — it obtains information from people. Source protection includes operational security about who knows what the researcher is working on.
Content-level analysis: A researcher who publishes an article that draws on specific non-public sources has, in some cases, revealed their research trail through the content itself, regardless of how private the research process was.
Legal compulsion of the researcher: Lawyers, journalists, and researchers in some jurisdictions have protections against being compelled to reveal their sources and research processes. These legal protections operate independently of technical privacy measures and are worth understanding before relying on technical measures alone.
Setup: An attorney researching an opposing party in a civil case. She doesn't want her research queries showing up in search engine logs that could be obtained by opposing counsel in discovery, and she doesn't want her research visible to her ISP or employer's network.
What she does:
She sets up a Firefox profile on her personal laptop (not her work computer, which logs traffic). The profile has no personal logins. She uses her personal home internet (not the firm's network). She installs uBlock Origin in the profile and enables Strict tracking protection in Firefox settings.
For search, she uses Startpage — it queries Google but returns results without tracking her queries.
She saves research findings to a Joplin notebook with E2EE enabled. Notes are encrypted before sync to her personal Dropbox.
She doesn't use Tor Browser because the research, while professionally sensitive, doesn't require protection against sophisticated surveillance. The dedicated browser profile plus privacy search engine substantially reduces the risk she's managing.
The result: Her ISP can see DNS queries to Startpage and to the sites she visits. Startpage doesn't retain her queries. The sites she visits see her home IP address (she's accepted this as a residual risk). Her research findings are encrypted in Joplin.
Doing research without being tracked is primarily a practice of tool selection and session discipline: the right tools (privacy-oriented search, browser configured for minimal fingerprinting, E2EE note capture) combined with consistent practices (no personal logins, dedicated research sessions) reduce the digital trail created by research activity. For most sensitive professional research, a dedicated browser profile plus a privacy search engine addresses the most significant risks without the operational complexity of Tor or dedicated devices. For high-stakes investigative work — journalism, legal defense, whistleblower assistance — the additional investment in Tor Browser, dedicated devices, and comprehensive operational security is appropriate and justified. The baseline practices are low-cost and should be standard for any professional whose research could be sensitive.
