Privacy Policy
What this is
This is a personal portfolio site of Yaroslav Kushchev. It has no accounts, no advertising and no third-party analytics or trackers. It keeps a small, anonymous count of visits for the author's own curiosity (described below). There are two places where you send something yourself: the contact form and free-form questions to Flipper, the site's guide (both described below).
Visitor statistics
To get a rough sense of where visitors come from, the site keeps an anonymous tally: the referring source (for example a search engine or a social network), the browser, operating system and device type, a two-letter country code and which page was opened. Your IP address is used only for a moment to look up the country offline and is never written down. There are no tracking cookies, no cross-site identifiers and no third-party services — the numbers stay on the author's own server and are only ever looked at in aggregate. The single cookie the site sets is a service one for the owner to sign in to a private panel; it is never set for visitors.
What the contact form collects
Only what you type: a name, a way to reach you back, an optional topic and your message. Nothing else is attached — no IP logging for profiling, no cookies for tracking.
Where it goes
The message is delivered straight to the owner's private Telegram through a bot, and a copy is kept on the owner's own server (next to the anonymous statistics, on no third-party service) so the history of enquiries isn't lost in the chat. It is used only to reply to you — not sold, shared or published — and is kept only as long as needed. Ask, and it's deleted.
Flipper, the AI guide
Most of Flipper's answers — the buttons, questions about projects, experience, skills, badges and articles — are put together right in your browser from the site's own content; nothing is sent anywhere. Only when you type a free-form question that Flipper can't answer by itself, the text of that question, the interface language and up to four previous messages of the conversation are sent from the site's server to Google's Gemini API (Google LLC, USA) to generate the reply. The request comes from the site's server, so Google sees the server's address, not yours; no name, contacts or other data about you are added. The site uses Gemini's free tier, and under Google's terms content sent on the free tier may be used to improve Google's products and may be reviewed by people — so please don't type personal or confidential information to Flipper. On the site's side the conversation is not saved: there are no chat logs, the history lives only in your open tab and is gone after a reload. To limit how often questions can be sent (protection against abuse), the server keeps your IP address in memory for about ten minutes; it is never written to disk. The browser's session storage keeps a single flag so the greeting hint isn't shown twice.
Your choice
You can reach out by Telegram or email instead of the form — the contacts are on the site. To have a message deleted, just ask through any of them. Flipper's AI mode is optional: everything on the site can be found without typing free-form questions.
