1. Data controller
The controller of otwarteAPI.pl is Bartosz Kuć (the same person who runs skanfirmy.pl), sole proprietorship, tax ID (NIP) 7393933151. Contact: firma@bartosza.pl.
2. What data we process
otwarteAPI.pl is a static catalog — there are no forms, accounts, or logins. The only "data" involved at all is the search query you type into the homepage search box, and that's filtered entirely locally, in your browser — it's never sent or stored anywhere.
3. How the live "Try it" buttons work
8 entries in the catalog have a live "Try it" button that runs a sample request directly from your browser to an official, external government or EU API (e.g. Poland's VAT White List, the NBP API, IMGW-PIB weather data) — exactly as if you'd opened that address yourself in a new tab. otwarteAPI.pl does not proxy or intercept that request: we don't see, capture, or store the request or the response it returns. That external API sees your IP address under the same terms as any direct visit to its own site would — that's outside our control and governed by that institution's own privacy policy, not ours.
4. Local storage
The accessibility bar (text size, contrast/yellow mode) remembers your choice only in your browser's localStorage. That's a UI preference, not personal data — it's never sent anywhere.
5. No tracking
We do not use tracking cookies, analytics, or advertising tools. We do not share any data with third parties.
6. Hosting
The site is hosted on Netlify. Beyond standard hosting-infrastructure logs (typical for any site on the internet), we keep no persistent database or visit log of our own.
7. Changes
We may update this policy. The current version is always available at this address.
Frequently asked questions
Does otwarteAPI.pl collect my personal data?
No. The site has no forms, accounts, or logins, uses no tracking cookies, and uses no analytics tools.
Who sees my request when I click "Try it"?
Only the external API your browser connects to directly (e.g. the VAT White List, NBP, IMGW-PIB) — otwarteAPI.pl doesn't proxy or see that request.
Does the site use cookies?
We don't use tracking cookies. The only local storage is the accessibility bar's preferences in your browser's localStorage, which is never sent anywhere.
