The short version
The content you paste into a tool is processed on your own device and is never transmitted to us. We do not have accounts, so we hold no profile about you. What we do collect is limited to standard web server logs and — where enabled — aggregate analytics.
The rest of this page is the detail behind those sentences.
What you paste into a tool
Almost every tool on this site runs entirely in your browser. Your input is read by JavaScript on the page, processed there, and displayed back to you. It is not sent over the network, not written to a server, and not logged.
That includes the inputs most worth protecting: tokens in the JWT decoder, passwords from the generator, connection strings, API responses. We could not disclose that data to anyone if we were asked, because we never receive it.
You can confirm this yourself. Open your browser's developer tools, switch to the Network tab, and use any tool — no request is made. The tools also keep working with the network disconnected.
The exception: a small number of tools have to contact the network to do their job, such as looking up a DNS record. Those tools are labelled, and the value you submit is sent to our server (and, where relevant, on to the service being queried) purely to answer that request. We do not retain those values.
What is stored on your device
The site uses your browser's localStorage for preferences only:
| Key | Purpose |
|---|---|
tp-theme |
Your light / dark / system theme choice |
tp-favorites |
Tools you have starred |
tp-recent |
The last few tools you opened, to show on the home page |
tp-split |
Where you dragged the divider between input and output |
tp-sidebar |
Whether you collapsed the left sidebar |
tp-consent |
Your analytics choice, so we stop asking |
This data stays on your device. It is not sent to us and not readable by anyone else. Clearing your browser storage for this site removes all of it.
Tool inputs are not persisted. Some tools keep your last input in sessionStorage so a page refresh does not lose your work; that is cleared automatically when you close the tab.
Server logs
Like any website, our host records basic technical information for each request: the IP address, the time, the page requested, the user agent string, and the referring page. This is ordinary web server logging, used to keep the site running and to investigate faults and abuse. We do not use it to build a profile of you.
The site is hosted on Railway. Hosting a website necessarily means the host processes these requests on our behalf.
Analytics
We use Google Analytics 4 to understand which tools people use and which pages are slow or broken — aggregate patterns, not individual behaviour. Google Analytics sets cookies and processes data on Google's infrastructure, which may include transfers outside your country.
Nothing analytics-related loads until you say yes. On your first visit you are asked, and until you accept, no Google script is downloaded and no analytics cookie is set. This is not limited to any particular country — everyone is asked, because guessing where you are would be both unreliable and beside the point.
If you decline, we clear any analytics cookie already set and stop asking. You can change your mind in either direction at any time through Cookie settings at the bottom of every page.
Declining does not affect any tool on this site; everything continues to work. A content blocker or the Google Analytics opt-out browser add-on also works.
Advertising
There are no ads on this site today. The intention is to fund it with advertising later, and this section describes what will apply when that happens — it is written in advance rather than added quietly on the day.
Where ads are shown, the ad provider may set cookies or use similar technologies to select and measure ads, and may process data such as your IP address and the pages you view.
You will be asked for consent before any non-essential cookie is set, and you can change or withdraw that choice at any time. Declining consent does not restrict access to any tool.
Ad providers publish their own privacy terms; where Google services are used, Google's advertising privacy notice applies to the data they process.
Your rights
Depending on where you live, you may have the right to ask what personal data we hold about you, to have it corrected or deleted, or to object to its processing.
In practice we hold very little: no account data, no tool inputs, and analytics that are aggregated rather than tied to an identity. If you want to make a request, use the contact page and we will respond.
Children
This site is aimed at software developers and is not directed at children. We do not knowingly collect personal data from anyone under 16.
Changes
If this policy changes in a way that affects what we collect, the change will be described here rather than quietly folded in.
