This plugin adds a checkbox to the profile page for users which allows them to opt into receiving a notification email whenever a comment is made to the site.
If a comment goes into moderation, only users who have the ability to manage comments on the site will receive the moderation notification email.
By default, all users of the site have the ability to subscribe to notifications about comments. A filter is provided to facilitate use of code to customize the feature’s availability to users.
Note: a “user” is a person with an actual login account for the site. The plugin does not facilitate permitting visitors who do not have an account on the site to be able to subscribe to all comments.

Why CommentBy?
Unlike Disqus and other comment systems, CommentBy doesn’t:

<li>Show advertisements in your comment section</li>
<li>Slow down your site with dozens of HTTP requests</li>
<li>Require complex API integrations or OAuth</li>

<h3>Privacy & Data Collection</h3>
CommentBy is designed with privacy as a priority. Here’s exactly what data we collect:
Data We Collect: 
– IP addresses (for rate limiting and spam prevention only) 
– Comment content (what users post) 
– Author name and email (if provided by the commenter)
What We DON’T Do: 
– Track users across websites 
– Build user profiles 
– Use tracking cookies 
– Sell data to third parties 
– Show advertisements 
– Collect browsing history
Why We Collect IP Addresses: 
IP addresses are used solely for rate limiting to prevent spam and abuse. They are not used for tracking, analytics, or any form of user profiling.
GDPR Compliance: 
CommentBy collects only the minimum data necessary for the service to function and complies with GDPR requirements. Users have the right to access, modify, or delete their data at any time.
Unlike Disqus (fined €2.5M for GDPR violations in Norway in 2022), CommentBy is built to be compliant by design.

<h3>About</h3>
CommentBy is built by developers who got tired of comment systems that track users everywhere and slow down websites. We wanted something simple, fast, and respectful of user privacy.
Why we built this: 
– Disqus was fined €2.5M for GDPR privacy violations 
– Existing alternatives are either too complex (self-hosted) or abandoned (Commento) 
– Bloggers and developers deserve better than surveillance-based commenting
Our principles: 
– Privacy by design, not as an afterthought 
– Fast and lightweight (your site’s performance matters) 
– Transparent pricing (no hidden fees or surprise costs) 
– You own your data (export anytime, no lock-in)
