Who we are
GridPass (working name) is an early-stage project by Andrii Shylenko and Simon Barczi, based in Warsaw, Poland. Contact for anything about your data: andrii@gridpass.eu or simon@gridpass.eu.
What we collect
- Contact form: the name, email, company, role and message you send, plus the campaign tag (e.g.
utm_source) and referring page, if any. We do not store your IP address. - Page views: a count per day with the campaign tag and the referring website. No cookies, no IP addresses, no identifiers, no advertising trackers.
- Optional 3D case-study: the 3D viewer loads a version-pinned software library from jsDelivr. That CDN may receive the browser's IP address and standard request data. If you choose to include a prospect's public logo URL, the browser loads it from the image host. We do not collect or claim an endorsement from that prospect. Scenario settings entered into the page are stored in the shareable URL, not an account. Anyone with the URL can see the included site name, location label and commercial assumptions. Do not include confidential information.
- Prospect studies: GridPass can prepare illustrative site cases using a site label, region, grid and battery assumptions, an optional public logo URL, and financial inputs. New studies are versioned in our private source repository and served as public site assets. Earlier published studies may also exist in Cloudflare Durable Object storage. Study pages request that search engines do not index them, but anyone who has a unique link may view the details. Publicly published details may persist in caches and deployment history even after a link is withdrawn. We do not require account creation for prospects. Never put confidential site or commercial data into a study link.
- Cloudflare Web Analytics: our host Cloudflare counts visits and page load times without cookies and without storing IP addresses or tracking you across sites. See Cloudflare's privacy policy.
Why, and on what basis
To reply to your enquiry and discuss a possible pilot or partnership (legitimate interest, GDPR Art. 6(1)(f), or steps before a contract, Art. 6(1)(b)), and to see which channels bring visitors (legitimate interest; data is aggregate and not linked to you).
Who processes it
Our website and contact form run on Cloudflare Workers. Contact enquiries are stored in Cloudflare Durable Object storage and may be accessed only by authorised GridPass operators. We may also use Hetzner Online GmbH (Germany, EU) for other internal services. We do not sell or share your details with third parties for advertising.
How long we keep it
Enquiries: up to 24 months after our last contact, unless we start working together. Page-view counts: up to 24 months.
Your rights
You can ask to see, correct, delete or export your data, or object to its use, by emailing us. You can also complain to your data protection authority (in Poland: UODO, uodo.gov.pl).
