Cookie policy
This page explains what HerHesap stores in your browser and how it uses Google Analytics 4. Calculations run in your browser; the values you enter are not stored.
What we use
| Name | Type and provider | Purpose | Lifetime | When |
|---|---|---|---|---|
hh-cerez | Browser storage (localStorage), HerHesap | Remembers your cookie choice: 1 accepted, 0 rejected. Never sent to the server. | Until you clear it | When you make a choice |
hh-tema | Browser storage (localStorage), HerHesap | Remembers your light/dark theme choice. Never sent to the server. | Until you clear it | When you switch the theme |
_ga | Cookie, Google Analytics 4 | Used to distinguish users. | 2 years | Only after you choose “Accept” |
_ga_<container-id> | Cookie, Google Analytics 4 | Used to persist session state (the name carries the part of the measurement ID after G-). | 2 years | Only after you choose “Accept” |
Cookie purposes and lifetimes are from Google’s documentation: [GA4] Cookie usage on websites. Chrome caps cookie lifetimes at 400 days, so in that browser the lifetime is 400 days: Chrome: cookie expiry upper limit.
Google Analytics and consent mode
We measure which pages and calculators are used with Google Analytics 4. Google Consent Mode v2 is used: until you choose, and if you reject, analytics and advertising storage are “denied”; the Google tag neither reads nor writes cookies and sends only cookieless pings (such as a timestamp, browser user agent, referrer, the consent state and a random number generated on each page load). Full measurement data is sent only after you choose “Accept”. (Google: Consent mode)
Even after you accept, advertising consent (ad_storage, ad_user_data, ad_personalization) stays denied; the site does no ad measurement or personalisation. If you accepted, the first time you change a value in a calculator a single “calc_used” event naming the calculator is sent; the values you enter are not.
If your browser sends a Global Privacy Control or Do Not Track signal, Google Analytics is not loaded at all and no consent is asked.
Google’s role
Google Analytics is one of the services Google provides as a data processor, under the Google Ads Data Processing Terms. Google states that IP addresses are not logged or stored in Google Analytics 4. For how Google processes data, see:
Changing your choice and withdrawing consent
You can change your choice at any time. The “Cookie settings” link at the bottom of every page, or the button below, reopens the consent banner. Choosing “Reject” updates consent to denied and deletes this site’s _ga cookies. You can also remove everything by clearing site data in your browser settings.
Admin panel
Only in the /yonetim section, used by the site administrator alone, a strictly necessary session cookie (hh_yonetim) is set; Google Analytics is not loaded there.
Data controller and contact
The data controller’s name, address and contact details will be added to this section shortly.
