Privacy Policy
In short: you do not need to give any information to use the calculators, and the numbers you enter never leave your browser.
Values you enter into calculators
Figures such as your salary, loan amount, height or weight are calculated in your browser only; they are not sent to or stored on the server.
When you use “Share”, the values are written into the link. Anyone you give the link to can see them.
If you create an account
An account is optional and only needed to keep your calculations. Your email address and a hash of your password are stored; the password itself is not.
Saved calculations are encrypted. The key is derived from your password, so nobody but you can read them — and they cannot be recovered if you forget the password.
You can permanently delete your account and everything saved in it on the Account page.
Information collected automatically
As with any website, the hosting provider keeps logs containing IP address, browser type and time of visit for security.
The site currently uses no visitor tracking or statistics service.
Exchange rates
The currency converter fetches rates from the public feed of the Central Bank of the Republic of Türkiye through the site’s server; nothing is sent from your browser to the bank.
Children
The site is for a general audience. Anyone under 18 should have a parent’s or guardian’s permission before creating an account.
