The short version
gart.io sets three cookies when you arrive: one holds your session, one your language and one your time zone. A fourth records the choice you make in the cookie bar.
We do not run Google Analytics, a tag manager or an advertising pixel on this site. Outside the EU, Cloudflare Web Analytics measures page views and load times without cookies; visitors in the EU do not get its script.
Your browser does contact two Google services: Google Fonts on every page, and Google reCAPTCHA on pages with a form. Outside services lists what each one receives.
Cookies we set
These cookies are set by the platform this site runs on.
| Cookie | What it does | Lifetime |
|---|---|---|
session_id |
Keeps your session: the shop cart, a form you are sending, your login if you have an account. | 7 days |
frontend_lang |
Remembers the language the site is shown in. | 1 year |
tz |
Holds your browser's time zone (for example Europe/Prague) so the site can show dates and times. | Until you close the browser |
website_cookies_bar |
Records the choice you made in the cookie bar, so the bar does not ask again. | 400 days |
Without session_id the shop cart and the forms do not work.

If you choose "Only essentials", the site does not store them.

Outside services
Loading a page from gart.io makes your browser contact a few other servers. Each of them receives your IP address and browser details, as any web server does.
Cloudflare
gart.io is served through Cloudflare, which sits between your browser and our server. Cloudflare can set its own security cookies, such as __cf_bm or cf_clearance, when it checks a suspicious request. We did not see one during a normal visit.
Cloudflare Web Analytics
For visitors outside the EU, Cloudflare adds its Web Analytics script (beacon.min.js, from static.cloudflareinsights.com) to every page. Visitors in the EU do not get the script. On each page view it reports to Cloudflare how long the page took to load and Google's Core Web Vitals measurements, together with the page address and the address of the page you came from. Cloudflare does not record the query part of a link. From these reports Cloudflare shows us page views and visits by page, referring site, country, browser, operating system and device type.
The script sets no cookie and writes nothing to your browser's storage. Cloudflare states that it does not use your IP address or browser details to recognize you. Cloudflare keeps the full reports for 7 days and a sample of about a tenth after that.
Google Fonts
Every page loads its typefaces, Inter and Zalando Sans Expanded, from fonts.googleapis.com and fonts.gstatic.com. Google receives your IP address with that request. It sets no cookie.
Google reCAPTCHA
Pages with a form (home, the app page, contact, the checklist sign-up) load Google reCAPTCHA from recaptcha.net and gstatic.com to tell people from bots. The script loads with the page. When you send the form, Google sets a cookie named _GRECAPTCHA on recaptcha.net for 180 days and writes _grecaptcha to this site's local storage. Google's privacy policy applies to that data.
jsDelivr
The stats page loads two open source libraries, Chart.js and html2canvas, from cdn.jsdelivr.net.
Payment providers
Our privacy policy names Stripe and BTCPay Server as payment processors. If you pay by card, Stripe's script runs in your browser at checkout and Stripe sets its own cookies to prevent fraud.
Your choices
The cookie bar offers two options. "Only essentials" stores the four cookies listed under Cookies we set. "I agree" also allows the three campaign cookies.
To change your choice, delete the website_cookies_bar cookie for gart.io in your browser settings. The bar asks again on your next visit.
You can block or delete cookies in your browser at any time. Each browser handles this in its own settings.
The site does not act on Do Not Track signals. The only cookies that record how you arrived are the three campaign cookies, and they are stored only after you choose "I agree".
Changes to this policy
We update this page when the cookies or the outside services change. The date at the top is the date of the last revision.
