Summary
This website does not require an account, does not ask for personal information, and does not collect the figures you enter into any calculator. Every calculation runs inside your own browser using JavaScript. Nothing you type is transmitted to this website, stored on a server, or shared with anyone.
No account required
There is no sign-up, no login and no user profile. You can use all twenty calculators without identifying yourself in any way.
Information the calculators handle
The numbers you enter — prices, costs, ad spend, order volumes and so on — exist only in your browser's memory for as long as the page is open. They are not sent anywhere, not written to a database, and not retained once you close or reload the page. Refreshing the page resets every calculator to its example values.
Cookies and analytics
At the time of writing, this site sets no cookies of its own and runs no analytics or advertising scripts. If analytics are added in future, this policy will be updated before they go live, the provider will be named here, and any cookie consent required in your jurisdiction will be requested at that time.
Third-party fonts
Typefaces are loaded from Google Fonts. When your browser requests a font file, Google receives your IP address and standard request information such as your browser type, as it would for any resource requested from a third-party server. Google's handling of that data is governed by its own privacy policy. No other third-party resources are loaded by this site — there are no external scripts, no embedded videos, no tracking pixels and no advertising networks.
Hosting and server logs
This site is a set of static files served by a hosting provider. Like almost all web hosts, the provider may keep standard server logs containing IP addresses, requested URLs, timestamps and user agent strings for security and operational purposes. Those logs are held by the host, not by this site, and are not used to build any profile of visitors.
External links
Pages may link to other websites. Once you follow such a link, this policy no longer applies and the destination site's own privacy practices take over. We have no control over, and accept no responsibility for, how other sites handle your data.
Children
This site is a business tool intended for adults. It is not directed at children and does not knowingly collect any information from them.
Your rights
Because no personal data is collected by this site, there is normally nothing to access, correct, export or delete. If you have contacted us by email, that correspondence exists in an ordinary email inbox, and you may ask for it to be deleted at any time by writing to mujtaba.developer@gmail.com.
Changes to this policy
If the way this site works changes — for example if analytics, advertising or an embedded third-party service is introduced — this policy will be updated and the "last updated" date at the top of this page will change. Continued use of the site after such an update constitutes acceptance of the revised policy.
