Privacy Policy

Effective date: October 16, 2026

MultiStreamWall is a web application for arranging and viewing multiple YouTube streams. This policy explains how information is handled when you use the service.

Information you provide

You can use MultiStreamWall without creating an account. Saved wall configurations, including profile names, stream names, YouTube URLs, layouts, and volume settings, are stored in your browser's local storage. You can clear them using your browser's controls.

If you choose to create an account, authentication is provided by Supabase. Signing in with Google may share basic account information such as your email address, name, and profile image with the authentication provider and MultiStreamWall. Email-link sign-in requires your email address. We do not ask for or receive your Google password.

Cloud profile storage

If you opt to use account syncing, your wall configurations are stored in a Supabase database associated with your account. This may include the YouTube video URLs and names you save. Account access controls are intended to limit access to your own stored profiles. Guest profiles remain on the device unless you choose to upload them.

Third-party services

MultiStreamWall embeds YouTube players. Google and YouTube may collect information, set cookies, or process data under their own policies when you interact with those services. Google authentication and Supabase also process information needed to sign you in and store your account data. Cloudflare provides website hosting and may process technical connection information to deliver and protect the site.

See Google's Privacy Policy, Supabase's Privacy Policy, and Cloudflare's Privacy Policy for details.

Use of information

We use information described above to operate the website, authenticate optional accounts, store and sync saved walls, troubleshoot problems, and protect the service. We do not sell your saved wall configurations or account information to advertisers.

Retention and your choices

You can use the site without signing in, delete local data through your browser, and stop cloud syncing by signing out. To request deletion of account-associated cloud data or ask a privacy question, contact multistreamwall@gmail.com. Browser data may remain on devices until cleared separately. Third-party providers may retain information according to their policies and applicable law.

Children's privacy

MultiStreamWall is not intended for children under 13. Please contact us if you believe a child under 13 has provided account information.

Changes

We may update this policy as the service changes. The effective date above indicates the current version.
