Cookie Policy
This page explains which cookies and similar technologies HEIC.IS uses and how you can control them.
Last updated: September 29, 2026
What are cookies?
Cookies are small text files stored by your browser. Similar technologies, such as local storage, work in a comparable way. We use them to make the website work and — only with your consent — to measure usage and show advertising.
Necessary
These are required for the website to function and can't be switched off. They don't track you across sites.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| heicis_consent | Cookie | Stores your cookie choices | 6 months |
| heicis_locale | Cookie | Remembers the language you selected | 1 year |
| heicis-theme | Local storage | Remembers light, dark or system theme | Until cleared |
| heicis-lang-suggest | Local storage | Remembers that you dismissed the language suggestion | Until cleared |
Administrators of the site additionally use a secure session cookie when signed in to the admin panel.
Analytics (optional)
If you allow analytics, we load Google Analytics 4 to understand how the site is used. Google Analytics sets cookies such as _ga and _ga_<ID> (up to 2 years). We never send image content, file names or metadata to analytics.
Advertising (optional)
If you allow advertising, Google AdSense may set cookies to deliver, personalise and measure ads (for example __gads, __gpi and other Google advertising cookies). Learn more in Google's advertising policy (opens in a new tab).
Managing your choices
When you first visit, you can accept all, reject all or customise your choices. You can change them at any time with the Cookie settings link in the footer. If you withdraw consent, analytics and advertising scripts stop loading and their cookies are removed where possible.
You can also block or delete cookies in your browser settings. Blocking necessary cookies may affect how the site works; the converters themselves don't depend on cookies.
Changes
We update this policy when we add or remove cookies. The date of the latest update appears at the top of the page.
