Cookies and local storage

Cookies policy

This website sets no cookies at all. We store a single item in your browser's local storage — your choice from the information bar. We use no third-party analytics or marketing tools.

Cookies and similar technologies

Cookies are small text files that a website stores in your browser. Similar technologies work the same way — your browser’s local storage and beacons (short notices sent to the server when a page loads). Their use is regulated by EU Directive 2009/136/EC and, in Slovakia, by § 55 of Act No. 351/2011 Coll.; the processing of personal data resulting from them is governed by the GDPR.

Below is exactly what this website actually does.

Cookies set by ioas.pro

None. The ioas.pro server sends no cookie to your browser — our responses contain no Set-Cookie header. We have no user accounts to log into, and no advertising or analytics cookies.

Browser local storage

Instead of cookies we use local storage (localStorage). Unlike cookies, its contents are never sent to the server — they stay on your device and are read only by this website’s JavaScript.

Item Purpose Lifetime Category
ioas_cookie_consent_v1 Remembers that you dismissed the information bar so it is not shown on every page. Contains the option you chose and the time of the click. Until you delete it in your browser (it has no expiry of its own) Essential
ioas_pw_sub, ioas_pw_art:<article> Access token for paid content, should you purchase it. Currently inactive — paid content is switched off and these items are never created. Until you delete it in your browser Essential
ioas_sid_v1 (in sessionStorage) A random session number so that we can tell which views and clicks belong to one visit. It contains nothing about you and nothing can be derived from it. Until you close the browser tab Essential

Our forms (contact, membership application, newsletter) work without cookies and without sessions — they are submitted directly and store nothing about you in your browser.

Traffic measurement without cookies

When a page loads, your browser sends a short notice to our /api/visit endpoint. It neither stores nor reads anything on your device. On our server, the first visit from a given IP address creates a record containing:

This serves solely as our own overview of site traffic — we do not combine it with advertising profiles, do not share it with third parties, and do not use it for profiling or targeted advertising. Visits identified as bots and search engines are not recorded.

The legal basis is the legitimate interest of the controller in understanding how the site is used (Art. 6(1)(f) GDPR). You may object to this processing at any time at gdpr@ioas.pro — we will delete the record.

Geolocation runs on our own server from a locally stored database. Your IP address is not sent to any external service.

What we measure on the page

So that we know which parts of the site are useful and where visitors lose the thread, we record — besides the page view — clicks on links and buttons, reading depth (25/50/75/100 %), time spent on the page and form steps (opening, starting to fill in, submitting). The data is sent to our own /api/ev interface.

What is not stored: your IP address (only a daily-salted fingerprint of it is kept, from which the original address cannot be recovered and which can no longer be matched with the previous day’s), the content you type into forms, or anything that would identify you. We use no cookies for this and do not track you across other websites.

If your browser has “Do Not Track” enabled, the measurement does not run at all.

Third parties

We use no third-party tools — specifically no Google Analytics, Matomo, Hotjar, Facebook Pixel, ad networks, social media buttons, embedded players or maps.

The site is built so that your browser downloads nothing from foreign domains:

Should this change in the future, we will update this page in advance and, for any tool that requires consent, ask for it first.
