Frequently Asked Questions
Are Infinity Tools free?
Yes. Every tool on Infinity Tools is free to use, including the YouTube Thumbnail Downloader, the YouTube Storyboard Downloader and the Sleep Calculator.
Do I need an account?
No. Every tool that's live today works straight away in your web browser, without an account or sign-up.
Is anything I type uploaded?
It depends on the tool, and our Privacy Policy has the details. The Sleep Calculator works entirely in your browser and never sends your times anywhere. The YouTube Thumbnail Downloader and YouTube Storyboard Downloader use the link you paste only to fetch that video's public images and data, and we don't keep a record of it.
