What the tools do with your data

Nothing leaves your browser. Every tool on this site is JavaScript running locally on your device. There is no server-side computation, no API call and no database. What you type is not transmitted, not logged and not stored, not even in your browser between visits.

One exception, only when you ask for it: the CSV cleaner's "Open in that tool" button and the homepage's quick-start buttons pass your table to another tool on this site through your browser's session storage. It stays in this browser tab, is read and deleted by the next page as soon as it opens, and would be discarded by the browser when you close the tab anyway. It never leaves your device.

You can verify this: open your browser's developer tools, go to the network tab, and use any tool. No request is made.

Server logs

The site is served from a web server that keeps standard access logs: the page requested, the time, your IP address, and your browser's user agent string. That is the ordinary minimum any web server records in order to function and to be debugged. These logs are not linked to anything you enter into a tool, because that data never reaches the server in the first place.

Analytics

This site uses Google Analytics 4 to count visits and see which pages are useful. It is configured with IP anonymisation on and Google advertising signals off, so it is not used to build an advertising profile of you. Google Analytics sets cookies in your browser; you can block them with any standard content blocker or your browser's own settings without affecting any tool on this site.

Advertising

This site carries advertising through Google AdSense, which is how it stays free. Google and its partners may use cookies and similar technologies to serve ads, including ads based on your prior visits to this or other sites.

You can control this directly with Google at Google Ads Settings, or opt out of third-party vendor cookies for personalised advertising at aboutads.info/choices. Ad blockers do not break anything on this site.

Advertising is confined to clearly marked slots and never runs inside or between the fields of a tool.

Affiliate links

Where a link to a retailer is an affiliate link, it is labelled as one at the point of the link. An affiliate link may earn a commission if you buy something, at no extra cost to you. No recommendation on this site is influenced by whether a link pays.

Cookies this site sets

None. The site itself sets no cookies and uses no local storage; the only browser storage it uses is the short-lived session storage hand-over described above. Any cookies present in your browser on these pages come from the third parties named above.

Children

This site is a set of general-purpose tools and is not directed at children under 13, and no personal information is knowingly collected from them.

Changes

This page describes the site as currently built and is regenerated with every deploy, so it reflects what is actually running rather than what was intended at some point in the past.
