Cookie Policy
Last updated:
Cookies are small files a website can save in your browser. Browser local storage does a similar job. This page lists everything this website saves on your device.
1. In short
This website sets no cookies. It has no analytics, no advertising tools and no social media plug-ins; fonts are served from our own server.
Two things are saved on your device: your choice in the cookie notice, and, on the page with the contact form, a technical entry of the Cloudflare Turnstile anti-spam check. Both are strictly necessary.
2. What is saved
| Name | Type | Purpose | Kept for | Set by | Category |
|---|---|---|---|---|---|
| stb-consent | Browser local storage | Remembers your answer to the cookie notice, with the date and the version of this policy | 12 months, or until you clear it | This website (first party) | Strictly necessary |
| cf.turnstile.u | Browser local storage of challenges.cloudflare.com (inside the anti-spam check frame) | Used by Cloudflare Turnstile for the anti-spam check on the contact form. Cloudflare does not publish a description of this entry | No expiry date: stays until you clear your browser data | Cloudflare, Inc. (third party) | Strictly necessary |

The stb-consent entry stays in your browser and is not sent to our server.
Cloudflare Turnstile loads only on the page with the contact form, as a frame from challenges.cloudflare.com. When we checked on 4 October 2026, it set no cookies and saved only the entry listed above; Cloudflare may change how Turnstile works. It processes your IP address and information about your browser and device — see the Privacy Policy.
3. Categories
- Strictly necessary: needed for the site to work, to remember your choice and to protect the contact form from spam. Does not require consent.
- Optional categories (analytics, advertising and the like): none. No such tools are installed, so the notice offers nothing to switch on. “Accept all” and “Reject all” only record that you have seen the notice.
4. How to change your choice
Use the “Cookie settings” link at the bottom of any page. You can also delete saved site data in your browser settings; the notice will then appear again on your next visit.
5. Changes
If the website starts to use new cookies or tools, this page will be updated first and you will be asked for your choice again.
This policy is published in English and Indonesian. If the versions differ, the English version prevails, unless the applicable law provides otherwise.
