Cookie Policy
Information under Section 109 of Slovak Act No. 452/2021 Coll. on Electronic Communications · effective from 11 November 2026
mumi.dev uses only cookies and similar technologies that are strictly necessary for the website to work or that remember a setting you chose. We do not use analytics, advertising or tracking cookies, and we do not load social-media pixels or third-party fonts.
1. What cookies and similar technologies are
Cookies are small text files that a website stores in your device through your browser. Browser storage (localStorage) works in a similar way. In this policy we refer to both as “cookies”.
2. Legal basis
We store the cookies listed below without your consent under Section 109(8) of Act No. 452/2021 Coll. on Electronic Communications, because they are strictly necessary to provide the service you explicitly requested (sending a form securely, showing the website in your chosen language and theme). Where personal data are involved, the legal basis is our legitimate interest in a secure and functional website (Art. 6(1)(f) GDPR). They cannot be switched off without affecting how the website works.
3. Cookies we use
| Name | Provider | Purpose | Duration |
|---|---|---|---|
mumi_sid | mumi.dev | security session holding the token that protects our forms (contact, brief, booking, review) against cross-site request forgery | until you close the browser |
lang_pref | mumi.dev | remembers the language you chose | 12 months |
__cf_bm, cf_clearance | Cloudflare | distinguishing people from automated traffic and protecting the website against attacks; set only when Cloudflare’s security checks need it | 30 minutes (__cf_bm); up to 1 year (cf_clearance) |
4. Browser storage
| Key | Purpose | Duration |
|---|---|---|
mumi_theme | remembers whether you chose the light or the dark theme | until you change it or clear your browser data |
mumi_cookie_consent | remembers that you have closed the cookie notice, so it is not shown on every page | until you clear your browser data |
5. Third-party content and links
- Portfolio previews. When you open the details of a project in our portfolio, the client’s live website is loaded inside the page. That website is operated by our client and may store its own cookies under its own privacy and cookie policy.
- External links. Links to WhatsApp, LinkedIn, GitHub and our clients’ websites open services of other operators, which process data under their own policies. Nothing is loaded from these services until you click.
6. Managing cookies
You can view and delete cookies and browser storage in your browser settings at any time, and you can block cookies altogether. If you block or delete the necessary cookies, the forms on this website may not work and your language and theme settings will be reset. Instructions are available in the help pages of your browser.
7. Changes and contact
- We will update this policy whenever we change the cookies we use. The current version is always published on this page.
- For questions, write to [email protected]. More about how we process personal data is in our Privacy Policy.
