This site shows no ads, sells nothing and has no accounts. Here is all it learns about you.

Vercel Web Analytics counts the pages people open: the page, the site you came from, your country, and your browser, system and kind of device. It sets no cookies and stores nothing on your device. A visitor is told apart only by a hash of the request, which Vercel discards after 24 hours, so I see totals, never who you are. I count visits because knowing which pages are read is what keeps the site worth reading.

When you first arrive, a small banner asks whether I may use Google Analytics. It loads only if you accept. It then sets two cookies, _ga and _ga_WWS35PRJKF, which let Google tell a returning visitor from a new one, and sends Google the pages you open. Advertising is switched off from the start: no ad cookies, no ad personalisation, nothing sent for ads.

You can change your mind at any time with Cookie settings, here or at the foot of any page. Declining after you accepted stops Google Analytics and deletes its cookies.

Your browser's local storage remembers your answer to the banner, and, if you play the state estimation game, your settings and your best score on each level. These stay on your device and are never sent to me. Clearing your site data removes them.

The demos run in your browser. In the share-rate project, the line you type is scored on your own device and never leaves it; to do that, your browser downloads a language model from Hugging Face and its code from jsDelivr, which see your IP address as any website you load something from does. Links to GitHub, LinkedIn, Google Drive and other sites lead to pages with privacy rules of their own.

Vercel hosts the site. Like every host, its servers handle your IP address and browser details to send you the pages you ask for, and keep them briefly in their logs to keep the service running and safe.

Clients read and sign our agreements on private pages that only their own link opens. Neither analytics service runs on those pages, and search engines are told not to list them. When you sign a document, I keep the name you type, the signature you draw, the time, your IP address and device, what you confirmed, your remarks, and a fingerprint (SHA-256) of the document as you signed it, and I note when your page and documents are opened. The documents, signatures and that record are stored in a Postgres database run by Neon in Frankfurt, in the EU.

I keep them as the record of our agreement, for as long as it and the law need them.

If you e-mail me, I keep your message and address to answer you and to pick the conversation up later. They go nowhere else.

I am in Serbia, so Serbia's Law on Personal Data Protection applies, and the GDPR does for visitors in the EU. You may ask me what I hold about you, have it corrected or deleted, take back a consent, or object to how it is used: write to milossaric@outlook.com and I will answer within a month. You can also complain to Serbia's Commissioner for Information of Public Importance and Personal Data Protection (poverenik.rs (opens in a new tab)), or to the data protection authority where you live.
