We never receive what you type into a tool

DevToolBench is a set of static files. Every formatter, generator and counter here runs as JavaScript inside your own tab: the text goes from the input box to a function and back to the screen, and no request leaves the page while that happens. No API and no database stands behind a tool, so your input has nowhere to go even in principle. Paste a production payload if you need to. It stays on your machine, and it is gone the moment you close the tab.

The site does run one piece of server code, and the next section describes it completely. It sits behind the two forms linked in the footer, it executes only when you press their send button, and it never sees anything beyond what you typed into them.

The two forms

Report a bug and Suggest a tool are the only part of DevToolBench that transmits anything at all. Nothing is sent while you are typing, and nothing is sent if you open one of them and walk away. The transmission happens once, when you press send.

A submission carries exactly this and nothing else:

• the fields you filled in — for a bug, the tool you selected, what you did, what you expected and what happened instead; for a suggestion, the tool you are missing, the problem it would solve and an optional link to something similar;
• your email address, but only if you chose to type one. The field is optional and a submission without it is read in exactly the same way — it simply cannot be answered.
• the address of the page you came from, and the user agent string your browser already announces to every site you visit. Both are printed on the form before you send it. A bug report without a browser version is usually unactionable, and asking for it in the open is better than collecting it quietly.

The submission reaches a small endpoint on this domain, which turns it into an email addressed to the person who maintains the site. Delivery goes through a message queue hosted on Amazon Web Services and then a mail service; no database is written along the way, and the queue holds the message only until it is sent. What survives is the email itself, in the maintainer’s mailbox, kept as any other piece of correspondence would be. An address you leave is used to answer you and for nothing else: no mailing list, no newsletter, no passing it on.

What your browser keeps locally

Two small values may be written to your browser’s localStorage. They live on your device only. They are readable by this site alone, never transmitted, and clearing your site data removes them.

• theme — light or dark, so the choice you make with the toggle survives a page load instead of flashing back on every navigation.

The promo slots on this site pick their creative at random on each page load, so no counter is stored for them.

No cookies are set by this site.

The promos you see

The only adverts here are our own. They point at Revin, the consultancy that builds this site, and they are marked up with rel="sponsored" because an advert is an advert even when the advertiser is us. Nothing is loaded from an ad network: the image or card comes from this domain, no third-party script runs, no cookie is set and no profile of you is built.

The links carry UTM parameters (utm_source, utm_medium and utm_campaign) so that Revin can tell how many visits arrived from this site rather than another. Those tags describe the source of the click, not the person clicking. You can strip them from the address bar and the destination behaves the same.

Hosting

The site is hosted on Vercel. Like any web host, Vercel handles the request your browser makes and may record standard operational data about it, such as the requesting IP address and user agent, for delivery, security and aggregate traffic figures. That is inherent to being served over the internet, applies to every site you visit, and it is not something we can see per-visitor or use to identify you. Vercel’s own privacy documentation is the authority on how long that data is retained.

Your rights

Under the UK GDPR you may ask to see the personal data an organisation holds about you, to have it corrected, or to have it erased. For everything except the two forms the honest answer is that there is nothing to hand over: browsing this site creates no account, no profile and no record in your name. If you did send a report or a suggestion with your address attached, that email is the one thing that exists, it sits in an ordinary mailbox, and asking for it to be deleted is enough — send the request through the bug form and quote the address you used, so the message can be found. Correspondence you have had with Revin separately is covered by their policy rather than this page.

Contact

No email address is published on this site, on purpose: an address in the page source is an address that gets harvested within days. Questions about this policy can go through the bug form, which reaches the same person, or to Revin, who will answer them.
