Cookie Policy
Last updated: 15 September 2026
1. What Are Cookies
Cookies are small text files stored on your device by your browser when you visit a website. They allow the site to remember information about your visit so that the experience is consistent across page loads.
We also use similar technologies such as local storage and session tokens. This policy covers all such technologies collectively.
2. Cookies We Use
We do not set any cookies on this website. Both analytics tools we use — Vercel Analytics and Umami — are cookieless by design. We do not use advertising cookies, social media tracking pixels, or any third-party retargeting technology.
2.1 Strictly Necessary — Vercel (No Cookies)
Vercel Analytics (our hosting provider) collects aggregated, cookieless traffic statistics — page views, referrers, and approximate country of origin — using techniques that do not require cookies and do not track individuals. No cookie is set. No personal data is collected. No consent required.
2.2 Analytics — Umami (No Cookies)
We use Umami, an open-source analytics tool we run ourselves (self-hosted, not a third-party SaaS), to understand how visitors use this site and which parts of the page get interacted with — for example, which button was clicked. Umami is cookieless:
- No cookie is set, and no persistent identifier is stored in your browser
- Same-day visitor counting uses a salted hash of your IP address and browser, discarded and regenerated every 24 hours — it cannot identify you across days or be reversed to your IP
- Pages visited, referrers, and interaction events are recorded in aggregate, without any personal identifier
No consent is required, since no cookie or persistent identifier is used. Legal basis: legitimate interests (GDPR Art. 6(1)(f)) in understanding how the site is used, so we can improve the product presentation.
2.3 Campaign Attribution — Session Storage (No Cookies)
If you reach this site from one of our own links — a post of ours on social media, a newsletter, a link we shared somewhere — that link carries campaign parameters in the address, such as utm_source and utm_campaign. We keep those parameters, and the page you landed on, in your browser's session storage, so that they are not lost while you move around the site, and we attach them to your order if you decide to buy. That is the only way we can tell which of our own posts brings a sale and which ones are a waste of everyone's time.
- No cookie is set
- What is kept is the label of the campaign, not a label for you: no identifier for you, your device or your browser is created or stored, and nothing at all is stored if you arrive without campaign parameters in the address
- It is deleted as soon as you close the tab. Session storage does not outlive the tab, so it cannot follow you from one visit to the next, or across other sites
- If you do buy, these parameters are attached to that transaction, and are therefore visible to us and to Paddle, our payment processor
Legal basis: legitimate interests (GDPR Art. 6(1)(f)) in knowing which of our own marketing works. Nothing here survives the tab and no identifier is created, so there is nothing stored on your device to consent to or to withdraw consent from later. If you would rather not send the parameters at all, remove them from the address bar before pressing Enter, or see section 4.
3. What We Do Not Use
- No advertising or retargeting cookies (Google Ads, Meta Pixel, etc.)
- No social media tracking buttons or embedded feeds
- No cross-site tracking of any kind
- No persistent cross-visit fingerprinting — Umami's daily visitor hash is discarded and regenerated every 24 hours
4. How to Control Cookies
Browser settings
All modern browsers let you view, block, and delete cookies. Since no analytics cookie is set on this site, blocking cookies in your browser has no effect on Vercel Analytics or Umami. If you want to prevent analytics collection entirely, use a tracker/script blocker (uBlock Origin, Privacy Badger, browser tracking protection) — this will stop the Umami script from loading. Either way, it will not affect the functionality of the website.
5. Third-Party Links
This website may link to external services (Steam, Paddle, YouTube demo videos, etc.). Those sites have their own cookie policies which we do not control and are not responsible for.
6. Changes to This Policy
We may update this Cookie Policy to reflect changes in the tools we use or in applicable law. The "Last updated" date at the top will be revised accordingly. Continued use of the website after changes are posted constitutes acceptance.
