Last updated: 9 November 2026
This Cookie Policy explains how we use cookies and similar technologies on siriussoftware.bg, why they may be used, and how you can manage your choices. It applies to both the English and Bulgarian versions of the website.

2. What are cookies?
Cookies are small files stored by your browser on your device when you visit a website. They can support essential website functions, remember preferences or, where you have given your consent, help measure website usage and advertising effectiveness.
Similar technologies, such as browser local storage and tags, may also be used. Storage periods depend on the particular technology: some data is removed when your session ends, while other data is kept for a defined period or until you delete it.
3. Categories of cookies
- Strictly necessary: support the website's core functions and security and may remember your cookie choices. Consent is not required where they are technically necessary to provide a service you have requested.
- Analytics: help us understand which pages are visited and how the website is used, allowing us to improve its content and performance. These are used only where the required consent has been given.
- Functional: enable additional features and personalised preferences. Where not strictly necessary, they are used with consent.
- Marketing: may help measure advertising campaigns and provide more relevant advertisements. They are activated only with consent, where such tools are implemented on the website.
4. Analytics tools and retention periods
The website may use Google Analytics 4 to measure traffic. When this service is enabled and you have consented to analytics cookies, its standard configuration may set the following identifiers:
| Cookie | Purpose | Provider | Default lifetime |
|---|---|---|---|
_ga | Distinguishes visitors for statistical analysis. | Google Analytics | Up to 2 years |
_ga_* | Persists session state for a specific Analytics identifier. | Google Analytics | Up to 2 years |
These are the service's default lifetimes and may be shorter depending on your browser or configuration. The presence of a tag management tool, such as Google Tag Manager, does not by itself mean that all analytics or advertising cookies are enabled.
For more information, see Google's documentation on GA4 cookies and Google's Privacy Policy.
5. How can you accept, reject or withdraw consent?
On your first visit, where non-essential cookies are used, you should be able to accept all, reject non-essential cookies or select categories individually. Rejecting non-essential cookies does not prevent access to the website's core content.
You can change your preferences and withdraw consent at any time using the website's “Cookie Settings” feature. Withdrawal does not affect the lawfulness of processing carried out before it. You may also need to remove cookies already stored on your device through your browser settings.
You can manage or delete cookies using your browser settings. Official instructions:
Blocking strictly necessary cookies may cause certain website functions to stop working correctly. Google also provides a Google Analytics opt-out add-on, which is an additional option and does not replace consent controls on this website.
6. Third-party links and content
Some links may take you to external websites, such as social media services. If you interact with embedded third-party content or services, those providers may process information under their own policies. Merely linking to an external website does not necessarily mean that it sets cookies when you open a page on our website.
7. Changes to this policy
We may update this policy when our technology or applicable requirements change. The latest version will be published on this page with its last updated date.
