1. Necessary cookies
The login (session) cookie keeps you signed in and ties a request to your account; without it login is not possible, and it lasts until you log out or the session expires. Short-lived values (authjs.csrf-token, authjs.callback-url) protect forms against submission from another site and return you to where you started. tz_firma (60 minutes) keeps you from being logged out mid-payment, tz_jezik (365 days) remembers your language, and tz_ga (365 days) remembers your banner choice. These cookies are essential for the service, so no consent is asked for them.
2. Public-page visit measurement
Without consent we record only the page, the referring site, the device type and tz_sid. Only with consent do we set tz_utm, which remembers where you first came from (30 days), and tz_pos, which tells a first visit from a return (180 days). tz_sid is not a cookie but a value in the browser tab's sessionStorage, a random number that links views within one visit and is cleared when you close the tab. Measurement runs on our own infrastructure (our server in the Netherlands, Leaseweb); data is not shared with third parties or used for advertising.
3. Google Analytics (consent only, public site only)
On the public site tezgafiskal.com, if you consent in the banner at the bottom of the page, Google Analytics (Google Ireland Ltd.) loads and sets the _ga and _ga_* cookies (up to 2 years), recording which pages you visit, from which device and source, with a shortened IP address. Until you consent it runs in Consent Mode, setting no cookies and identifying no visitor. Your choice is stored in the tz_ga cookie (365 days); refusing also turns off tz_utm and tz_pos, and the app and admin never load Google Analytics.
4. How to delete them
You can delete or block all cookies in your browser settings, usually under privacy and site data. If you block the necessary cookies, logging in to Tezga will not work.
5. Changes
Any new third-party tool that sets cookies enters this policy before it is introduced and asks for your consent before setting cookies, as Google Analytics did in version 1.1. Each version of this document carries a version mark and effective date.
