Privacy Policy
No cookies, no analytics, no tracking, and nothing you type ever leaves your browser. Here is the detail.
The short version
This site does not ask for your name, does not set advertising cookies, and does not send the expressions you type anywhere. Conversion happens entirely inside your own browser.
Expressions you convert
Every converter on this site runs as JavaScript in your browser. The expressions you enter are processed on your own device and are never transmitted to us or to anyone else. They are not logged, not stored and not seen by us.
One consequence worth knowing: when you use the converter, the expression is placed in the page address so the result can be bookmarked and shared. That address is handled by your browser like any other URL, which means it can appear in your browser history. If you would rather it did not, clear the field or use a private window.
Local storage
The site stores a single value in your browser's local storage:
| Name | Purpose | Expires |
|---|---|---|
| ipc-theme | Remembers whether you chose the light or dark theme | Kept until you clear your browser data |
This value stays on your device. It is not a cookie, it is never sent to a server, and it contains nothing that identifies you. Clearing your site data removes it and the site returns to following your operating system's theme setting.
Cookies
This site sets no cookies of its own and uses no third-party cookies.
Server logs
The site is served by a hosting provider which, like virtually all web hosts, keeps standard access logs. These typically record the IP address of the request, the page requested, the time, and the browser's user-agent string. They are generated by the hosting infrastructure for security and reliability purposes, are not used to build any profile of you, and are not combined with any other information.
Analytics and advertising
At the time of the date above, this site runs no analytics, no tracking pixels and no advertising. If that changes, this page will be updated before the change goes live, and it will say which provider is used and what it collects.
If you email us
The contact form does not submit anything to this website. It builds a
mailto: link and hands it to your own email application, so nothing is
sent until you press send in your own client.
If you do write to us, we hold your message and your email address for as long as it takes to deal with it, and use them only to reply. They are not added to a mailing list and are not shared with anyone.
External links
Some pages link to other websites. Once you follow a link, that site's own privacy practices apply and this policy no longer does.
Children
The site is aimed at students and developers and collects no personal information from anyone, of any age.
Your rights
Data protection law gives you rights to access, correct and erase personal data held about you. Because this site collects none, there is in practice nothing to access or erase — except any email correspondence you have sent us, which we will delete on request. Write to us using the contact page.
Changes to this policy
If this policy changes, the date at the top of the page changes with it. Material changes — new analytics, advertising or anything that collects data — will be described explicitly rather than folded in silently.
