What is double opt-in and why use it:
Double opt-in is the safe way of receiving site visitor’s submitted input. Used with contact forms or online questionnaires or with user registration, it helps to reduce spam submissions. With GDPR laws, double opt-in is a strongly recommended way of getting user data. Because submitters have to confirm their identity from their email address, you can reduce risk of processing personal data without permission. Double – means here that user submitting the data has to give consent by checking checkbox option and additionally confirm their email-address. 
Do not forget to set acceptance field in your CF7 form if GDPR is in concern!
How Double opt-in form works:
When someone fills and submits a form with double opt-in functionality, the first CF7 email goes back to THEM. There is a confirmation link in that email, which the submitter has to click on or paste in their web browser. The link has two encrypted parameters: submission serial number and submitter email address. The page with “opt-in” slug validates the parameters with submission stored in WordPress database and initiates sending of final emails to recipient set in “All Opt-In Forms” settings. If validation fails or when submission has expired, no emails are sent. If there are no specified parameters in the URL, visitors of the “opt-in” page are redirected to “404” page.
Plugin translation
Double Opt-In can be easily translated. It is released with the translation to Polish language.

Short Description: Hands-free voice navigation and accessibility plugin for websites.
<h3>Source Code</h3>
The unminified, human-readable source code for all JavaScript and CSS used in this plugin is included in the <code>/source</code> directory. 
These source files were manually minified and/or obfuscated to create the optimized versions located in the <code>/assets/</code> directory. No automated build tools (e.g., Webpack, Gulp) were used in this process.
<h3>What Is voNavPilot?</h3>
voNavPilot©2025 lets users navigate your site using voice commands. With just one key press, visitors can control everything hands-free — no mouse or keyboard needed. Designed for accessibility and ease of use, the plugin supports voice-activated actions like scrolling, clicking, reading content, and switching languages, making your site more inclusive and user-friendly. The initial version focuses on essential features for seamless website navigation.
<h3>How It Works</h3>
voNavPilot© introduces seamless, voice-driven navigation. When your site loads, it welcomes users with a voice prompt: “Welcome to voNavPilot©, your voice navigation assistant. Press any key to start voice control.” A single key press starts hands-free browsing. The plugin uses a dynamic command engine to respond to voice input for scrolling, opening links, filling forms, and triggering accessibility features like zooming, grayscale mode, or reading content aloud. Commands are customizable in five major languages—English, German, French, Spanish, and Italian.
Under the hood, voNavPilot© uses: 
– fuzzysort v3.1.0 – Fast fuzzy string sorting
