Introduction

Welcome to the Watch Later button extension for YouTube™. This extension is designed to provide a simple and efficient way to add videos to your “Watch Later” playlist on YouTube. Your privacy is important to us, and this policy is intended to help you understand what information we handle and your rights.

Last Updated: May 14, 2026

Data Collection and Usage

We are committed to protecting your privacy. The Watch Later button extension does not collect, store, share, or transmit any of your personal data.

The extension’s functionality is limited to interacting with the content on the YouTube page you are viewing. It adds a “Save to Watch Later” button and, when clicked, communicates directly with YouTube’s services to add a video to your “Watch Later” playlist. All actions are performed locally in your browser, and no information about your activity is sent to our servers or any third parties.

Permissions

To function correctly, the Watch Later button extension requires permission to access content on https://www.youtube.com/*. This permission is used exclusively for the following purposes:

To identify the video you are watching.
To add the “Save to Watch Later” button to the YouTube page.
To send the “add” action to YouTube’s services when you click the button.

We do not use this permission to track your browsing history or collect any other information.

For the Watch Later Button Extension: The extension does not collect personal data, so GDPR Article 5 and other data protection principles do not apply to the extension itself.

For the Website: This website collects analytics data through Umami. The processing of analytics data is based on our legitimate interest under GDPR Article 6(1)(f) in understanding how users interact with our website and improving the user experience. This constitutes a balance between our business needs and your privacy expectations.

Under GDPR and German data protection laws, you have the following rights regarding data collected on our website:

Right of access: You may request information about what analytics data we have about your visits
Right to deletion: You can opt out of analytics collection (see Opt-Out section above)
Right to data portability: We can provide a summary of the data collected about you
Right to object: You can object to analytics data collection at any time
Right to withdraw consent: You can opt out of analytics tracking using Do Not Track (DNT)

For the Watch Later Button Extension: Since the extension does not collect personal data, no data subject rights are applicable to the extension itself.

To exercise any of these rights or for any data protection inquiries, please contact us at the address provided in our Legal Notice (Impressum).

Website Analytics and Cookies

This website uses Umami Analytics, a privacy-focused analytics tool that is self-hosted on our own infrastructure at https://uptime.alxple.com/.

Umami is designed with privacy in mind and fully complies with GDPR requirements.
