We Anonymized 12 Million Links. Here's What the Data Reveals About Online Privacy
Since launching Anonymiz, we've processed over 12 million link anonymizations through our Dereferer tool. That's 12 million moments where someone decided they didn't want a website knowing where they came from.
We've never published what that data shows. Until now.
What Your Referrer Header Actually Reveals
Every time you click a link, your browser automatically sends a Referer header to the destination website. This header contains the full URL of the page you came from — including search terms, the specific article you were reading, even internal page parameters.
Example: You're reading a Reddit thread about medication side effects and click a link to a pharmaceutical site. That site receives:
Referer: https://www.reddit.com/r/AskDocs/comments/abc123/side_effects_of_[medication_name]/The destination now knows: you came from Reddit, you were reading about that specific medication, and they have your IP address. Without an anonymizer, this happens silently on every single click.
What 12 Million Anonymizations Tell Us
Here's what our data shows about who uses referrer privacy tools and why:
Where People Are Anonymizing Links From
| Source Platform | Share of Anonymized Links | Year-over-Year Change |
|---|---|---|
| 31% | +12% | |
| Twitter / X | 24% | -8% |
| 12% | -15% | |
| Discord | 11% | +340% |
| Telegram | 8% | +180% |
| Corporate/Work environments | 7% | +340% |
| Other | 7% | +22% |
The two fastest-growing categories — Discord (+340%) and corporate environments (+340%) — tell an important story about why people use anonymization tools.
When People Anonymize Links
Privacy tool usage isn't uniformly distributed across the day. Our data shows a clear peak:
- Peak hours: 9pm–11pm local time — people browsing privately at home after work
- Secondary peak: 12pm–1pm — lunch hour browsing on work devices
- Lowest usage: 6am–9am — morning routines, less privacy-sensitive browsing
The lunch hour peak is particularly revealing. It aligns directly with the corporate segment growth — people are browsing during work hours and don't want their employer's network monitoring to see where they're going.
Why People Anonymize Links
Based on user surveys and support conversations:
- 78% — Avoiding tracking pixels and analytics on the destination site
- 67% — Don't want the destination to know they came from a specific community (Reddit, Discord, etc.)
- 43% — Corporate/work browsing privacy
- 31% — Sharing links in private messaging without exposing the source
- 18% — Research and journalism
3 Use Cases We Never Anticipated
When we built Anonymiz, we expected privacy-conscious individuals. What we didn't expect were these three major use cases:
1. Corporate Employees Hiding Browsing From IT Departments
This is now our fastest-growing user segment, up 340% year-over-year. Corporate networks log all outbound HTTP traffic, including referrer headers. When an employee clicks a link from an internal Slack message, their company can see both the source (your internal Slack channel) and destination.
Employees use anonymizers to break this chain — not to hide illicit activity, but to maintain basic browsing privacy from overzealous monitoring.
2. Privacy Researchers Investigating Sites Without Detection
Security researchers regularly told us they use Anonymiz to probe suspicious websites without alerting the site operators that they're being investigated. A researcher coming from securityresearch.org sends a clear signal. A researcher coming from a dereferer sends nothing.
3. Journalists Researching Sensitive Topics
Journalists working on sensitive stories — corruption investigations, health topics, legal matters — use referrer anonymization to research without leaving a trail. If you're investigating a company and you visit their website from your newsroom's IP and referrer, they know you're looking. Anonymized, they don't.
The One Stat That Surprised Us Most
89% of our users anonymize links before sharing them in private messaging apps — Signal, Telegram, Discord, WhatsApp.
The logic: you're sending a "private" message, but the link destination can still see where the click came from. If you share a Reddit link in a Signal conversation, the site you're linking to sees the Reddit source. True private link sharing requires anonymizing the link first.
