What we collect,and what wenever collect.
ARLing s. r. o. runs the tools on arling.sk. This page says plainly what happens to your data.
Last updated 5 September 2026.
On this page
1. The tools
Every tool runs entirely in your browser. What you paste into a form (URLs, configuration, XML files) is processed on your device and never sent to us or to anyone else. You can verify this in the page source on GitHub.
2. Visit counts
We count page views and button clicks with self-hosted Umami on our own server. Umami sets no cookies and stores no personal data: no IP addresses, no names, no content of what you type. It records the page, the country, the browser type and which buttons were used. That is why there is no cookie banner: there are no cookies.
3. The e-mail list
If you enter your e-mail in a "Tell me when a new tool lands" form, we store the address, the tool where you signed up, the language and the date. Nothing else. We use it only to tell you when a new tool is live. We do not send newsletters, we do not share or sell the list, and we do not track opens.
To be removed, reply to any mail we send or write to andrej@arling.sk. We delete the address within 7 days.
4. Feed Doctor Monitor
This is the one opt-in exception to section 1: if you sign up for Feed Doctor Monitor (a paid add-on to the free Feed Doctor checker), it stores your e-mail, the feed URL and each check's results (score and issue counts); feed content is not stored. Its server fetches only the feed URL you gave it, on the schedule you chose (weekly on the free plan, daily on Pro), to alert you when something got worse. Delete it any time from the monitor page or by replying to an alert e-mail; deleting removes the e-mail, feed URL and history.
5. E-mail and GitHub
If you write to us or open a GitHub issue, we keep that correspondence to answer you. Legal basis for all of the above: our legitimate interest in running the tools and your consent for the e-mail list and opt-in add-ons (GDPR art. 6(1)(a) and (f)).

Traffic we count with our own Umami on our own server. Umami sets no cookies and stores no personal data: no IP addresses, no names, no form content. That is why we have no cookie banner: we have no cookies.
The e-mail list: if you enter your e-mail in the "Tell me when a new tool lands" form, we store the address, the tool, the language and the date. We use it only to send word of a new tool.
