Selenium has introduced a Privacy Policy to clarify our data collection practices, why telemetry exists, and how we ensure compliance with GDPR and CCPA.
10+
---
11+
12+
Selenium has always been committed to open-source transparency and user privacy, but we recognize that
13+
we could have done a better job communicating the details of Selenium Manager's telemetry collection.
14+
15+
To address this, we have published a comprehensive [Privacy Policy](/privacy) that
16+
clearly explains:
17+
* What data is collected (and what isn’t)
18+
* How we ensure compliance with GDPR and CCPA
19+
* Why Selenium Manager includes opt-out telemetry
20+
* How users can easily disable telemetry
21+
22+
The bottom line is that Selenium Manager collects only anonymous technical information to help us improve Selenium.
23+
24+
Additionally, starting in Selenium 4.30, Selenium Manager displays a one-time console message the first time
25+
telemetry is sent. This obviously and proactively informs users about telemetry, their right to opt out,
26+
and provides a direct link to the Privacy Policy.
27+
28+
**Quick Recap of what Selenium Manager collects:**
29+
30+
✔ Selenium version (to ensure compatibility across versions)
31+
✔ Programming language (Java, Python, JavaScript, .NET)
32+
✔ Operating system and CPU architecture (to prioritize OS support)
33+
✔ Browser and version (to understand browser usage trends)
34+
✔ Approximate geolocation (city-level), temporarily inferred from the IP (IP is discarded after processing)
35+
36+
❌ No usernames, emails, or personal identifiers
37+
❌ No browser history or test execution data
38+
❌ No full IP addresses (only used temporarily for location inference, then discarded)
39+
❌ No cookies or persistent tracking
40+
41+
See everything for yourself: [Selenium Manager Public Analytics](https://plausible.io/manager.selenium.dev)
42+
43+
44+
## Opting Out of Telemetry
45+
46+
Like many other open-source projects, we use opt-out telemetry to ensure we receive representative, anonymous data that
47+
helps improve Selenium. We understand that some people prefer opt-in telemetry,
48+
and we explain our reasoning in detail in the [Privacy Policy](https://www.selenium.dev/privacy/#opt-out)
49+
50+
Regardless, it is quite easy to disable telemetry by either:
51+
52+
1. Setting an environment variable
53+
54+
```sh
55+
SE_AVOID_STATS=true
56+
```
57+
58+
2. Using a configuration file
59+
60+
```ini
61+
avoid-stats = true
62+
```
63+
64+
Please see the [Selenium Manager documentation](https://www.selenium.dev/documentation/selenium_manager/) for further
65+
details on how to do this.
66+
67+
## Insights
68+
69+
**Interesting tidbits we’ve learned from having opt-out telemetry over the past year:**
70+
71+
* Selenium gets over 1 million unique users a week
72+
* The number of unique users is growing at a rate of 10% per month
73+
* Over 80% of sessions are on Windows
74+
* Almost 90% of sessions use Chrome
75+
* Fewer than 1% of sessions are with Safari or Internet Explorer
76+
* A lot more sessions are with C# and Python than Java, and very few people are using Ruby and JavaScript
77+
78+
<em>Note 1: The data only represents users who have updated to Selenium 4.19 or greater</em><br />
79+
<em>Note 2: A unique user represents a unique session from a given IP address for that day</em><br />

111+
<div class="w-lg-75">
112+
<p>
113+
Selenium Manager’s telemetry is designed to comply with GDPR and CCPA by collecting only anonymized,
114+
non-personal data and providing users full control over their participation.
115+
Below is a detailed breakdown of compliance with key GDPR provisions.
116+
</p>
117+
118+
<h4>Lawfulness & Transparency (Articles 5, 6, 12)</h4>
119+
<ul>
120+
<li>Selenium Manager processes anonymized, non-personal data under legitimate interest
121+
(Article 6(1)(f)), allowing data collection for product improvement while respecting user privacy.
122+
</li>
123+
<li>Users are informed about telemetry collection through:
124+
<ul>
125+
<li>Change logs and documentation updates</li>
126+
<li>Blog posts</li>
127+
<li>A one-time console message when telemetry is first sent</li>
128+
</ul>
129+
</li>
130+
</ul>
131+
132+
<h4>Data Minimization & Purpose Limitation (Articles 5, 25)</h4>
133+
<ul>
134+
<li>Only essential, anonymous usage data is collected to guide project improvements.</li>
135+
<li>IP addresses are not stored; they are used temporarily to derive city-level geolocation before being
136+
discarded.
137+
</li>
138+
<li>Data is not used for advertising, profiling, or tracking individual users.</li>
139+
</ul>
140+
141+
<h4>User Rights (Articles 12-23)</h4>
142+
<ul>
143+
<li>Right to Object (Article 21): Users have the right to object to the processing of
144+
their data under legitimate interest. Selenium Manager respects this right by providing:
145+
<ul>
146+
<li>clear and accessible opt-out mechanisms, allowing users to disable telemetry at any time.
147+
</li>
148+
<li>information regarding the user's right to opt out via the measures detailed in the
149+
Lawfulness & Transparency section above.
150+
</li>
151+
</ul>
152+
</li>
153+
<li>Right to Access, Rectification, and Erasure (Articles 15-17): These rights apply when personal data
154+
is collected and stored. Since Selenium Manager only processes anonymous, non-personal data and does
155+
not retain user information, these rights are not applicable.
156+
</li>
157+
</ul>
158+
159+
<h4>Storage & Security (Articles 5, 32)</h4>
160+
<ul>
161+
<li>Data is aggregated and anonymized, ensuring no link to individual users.</li>
162+
<li>No long-term storage of raw data; all processing is done within GDPR-compliant
163+

Everything Selenium Manager collects is publicly accessible in the

177+
<div class="w-lg-75">
178+
<p>
179+
While some open-source projects use opt-in telemetry, Selenium requires a representative dataset to
180+
accurately assess project usage and prioritize improvements. With multiple language implementations and
181+
distribution methods, opt-in telemetry would not provide meaningful insights, particularly for
182+
cross-language comparisons.
183+
</p>
184+
<p>
185+
Many well-known open-source projects, such as <a
186+
href="https://learn.microsoft.com/en-us/dotnet/core/tools/telemetry">.NET CLI</a>, <a
187+
href="https://docs.brew.sh/Analytics">Homebrew</a>, <a
188+
href="https://nextjs.org/telemetry">Next.js</a>, and <a
189+
href="https://docs.gitlab.com/ee/user/admin_area/usage_statistics.html">GitLab</a>, use opt-out
190+
telemetry for similar reasons. </p>
191+
<p>Additionally, Selenium faces unique challenges in even providing an
192+
opt-in mechanism — there is no universal way to prompt users across all language bindings and package
193+
distribution methods. An unrepresentative dataset would prevent us from accurately assessing project
194+
usage and making informed improvements. For Selenium, the real choice is not
195+
between opt-in and opt-out, but between opt-out and no telemetry at all.

If you prefer not to share anonymous usage data, you can disable telemetry, the detailed instructions

can be found in the <a href="../documentation/selenium_manager">Selenium Manager Documentation</a>,
208+
but broadly consists of
209+
methods:
210+

211+
<h4>Option 1: Use an Environment Variable</h4>

<pre><code>avoid-stats = true</code></pre>

Once disabled, Selenium Manager will not send any telemetry data.
