What RunTimeIndex collects, what it does not collect, and how advertising works on this site. Last updated November 12, 2026.
The short version: RunTimeIndex does not collect personal information. There are no accounts, no sign-ups, no email list, and no analytics. The tools run in your browser, and your files stay on your device. A few settings are saved in your own browser only, and they never leave it. Advertising may use cookies, and you can opt out of personalized ads.
RunTimeIndex does not collect your name, email address, mailing address, phone number, or payment details, because the site never asks for them. There is no account to create, no profile, and no way to sign in. The site does not use analytics or tracking scripts, so it does not record which pages you visit, how long you stay, or what you click. It does not build a profile of you, and it does not sell or share personal information, because it does not have any to sell or share.
The tools, calculators, and converters on this site run entirely in your web browser. When a tool processes a file, such as a PDF, an image, or a spreadsheet, that file is processed locally on your device and is not uploaded to a server. Your work stays on your computer.
Some tools need an outside service to do their job, for example looking up DNS records, checking an IP address, or fetching public registry data. Each tool names the service it uses in the privacy box on its own page. Only the information that tool needs is sent, such as a domain name or an address you entered. RunTimeIndex does not send your name, email, or other identifying details to these services, because it does not collect them.
Two small settings are saved in your browser using local storage, and only in your browser:
These settings never leave your device. They are not sent to RunTimeIndex or to anyone else, and there is no central record of them. Clearing your browser data removes them.
RunTimeIndex may display ads served by Google AdSense. When ads are shown, third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site or other websites. Google's use of advertising cookies, including the DoubleClick cookie, enables it and its partners to serve ads to you based on your visit to this site and other sites on the Internet.
You may opt out of personalized advertising by visiting Google Ads Settings. You may also opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info/choices. If you opt out, you will still see ads, but they will not be personalized to you.
