Cookie Policy

oncehesap.com uses cookies and similar technologies to remember your preferences, to measure how the site is used and to fund the site through advertising. This page explains which cookies are used and how you control them.

What Cookies Are

A cookie is a small text file that a site stores on your device so that it can recognise the device on a later visit. Some cookies are set by us, others by third parties such as Google.

Categories of Cookies We Use

Strictly necessary

  • hesap_lang — remembers the language you are reading the site in, so that the address "/" sends you to the right version. Lifetime: 1 year. Set by us. Contains no personal data.
  • The consent record set by our consent management platform, so that we do not ask you the same question on every page. Without these cookies the site cannot work properly, so they do not require consent.

Analytics

  • Google Analytics (cookies beginning _ga, e.g. _ga and _ga_<id>) — anonymous statistics about page views, session length and the general country of visitors, so that we know which calculators are used and in which languages. Lifetime: up to 2 years. Set by Google. Where consent is required, these load only after you accept.

Advertising

  • Google AdSense and its partner vendors (for example cookies such as IDE, test_cookie or __gads) — used to select the ads you see, to limit how often you see the same ad, to measure whether an ad worked and to detect click fraud. Where you have consented to personalised advertising, these cookies allow Google and its partners to use your prior visits to this and other sites to choose ads. Lifetime: from a few minutes up to about 2 years, depending on the cookie. Set by Google and other advertising vendors.

You can read how Google uses this data at How Google uses information from sites or apps that use our services.

Consent

We use FlexyConsent as our consent management platform. If you visit from the European Economic Area, the United Kingdom or Switzerland, a banner asks for your choice before any analytics or advertising cookie is set; only strictly necessary cookies are set beforehand. You can accept all, refuse all, or choose by category.

Changing or Withdrawing Your Consent

You can change your mind at any time:

  • Open the consent settings from the banner or from the consent panel shown below on this page, change your choice and save it. The new choice applies immediately.
  • Withdrawing consent stops further processing; it does not undo processing that already took place while your consent was valid.

You may also turn off personalised advertising, whatever you have chosen here, at Google Ads Settings, and opt out of many third-party advertising vendors at www.aboutads.info/choices. Refusing advertising cookies does not remove the ads; it means they are chosen without using your prior browsing.

Browser Controls

Every major browser lets you block or delete cookies — usually under Settings, then Privacy. Blocking all cookies will also remove the language preference and your saved consent choice, so the site will ask again.

Cookies and Consent on This Site

The panel below shows the cookies and the consent record currently stored on your device by this site, and lets you change your choice.
