Frequently Asked Questions

Is SmartTube legal?

SmartTube is legal—it’s an open-source YouTube client. However, it blocks ads which violates YouTube’s Terms of Service. You won’t face legal issues, but theoretically Google could ban your account (this is extremely rare).

Is SmartTube safe?

Yes. SmartTube is open source, meaning anyone can inspect the code. It’s maintained on GitHub with thousands of users. Download only from official sources (smarttubenext.com or GitHub).

Will my YouTube account get banned?

Highly unlikely. Millions of people use ad blockers and alternative YouTube clients without issues. Google has never mass-banned accounts for this.

Does SmartTube work with YouTube Premium?

Yes, but there’s no benefit. SmartTube already provides ad-free viewing and background playback for free. Your Premium subscription features still work, but they’re redundant.

Can I cast to SmartTube from my phone?

No, casting isn’t supported. You need to search for videos within SmartTube. However, your watch history syncs, so you can find recently watched videos easily.

Does SmartTube support YouTube Music?

SmartTube focuses on video content. For music, use the official YouTube Music app or a music-focused alternative.
