Privacy policy

01Who is the controller

The data controller is Andrei Niachai, Warsaw, Poland, who runs SiteBest (sitebest.eu). For any matter concerning personal data, you can write to the email address given on the contact page.

contact@sitebest.eu

02Cookies and analytics

This website sets no cookies and uses no tracking tools, third-party analytics, advertising pixels or social media plugins. It only counts anonymous statistics for Bit and the "Does AI recommend your business?" tool (such as language and result, with no content, IP addresses or personal data). Fonts are loaded from the same server, not from external services.

In your browser’s storage (localStorage) I save only three settings: whether you turned animations off with the switch in the footer, whether you chose the light theme and which language you picked with the language switch. This is not personal data, it never reaches me or anyone else, and you can remove it by clearing this site’s data in your browser.

03Hosting

The website runs on Cloudflare infrastructure. On every visit Cloudflare processes technical data such as your IP address and browser information to deliver the website and protect it from attacks. The rules are described in Cloudflare’s privacy policy.

04When you send an email or use the form

If you write to me, I process your email address, your name and the content of your message and, when you use the form, also your business name, industry and the needs you tick, if you provide them.

• Purpose: replying to your message, preparing a proposal and quote and, if we start working together, carrying out the work.
• Legal basis: Article 6(1)(b) GDPR (steps taken at your request before entering into a contract, and performance of the contract) and Article 6(1)(f) GDPR (legitimate interest, namely handling correspondence).
• Retention: for the duration of our conversation and, if we do not start working together, no longer than 12 months after the last message. If we sign a contract, for as long as the law requires, e.g. tax law.
• Recipients: the provider of the mailbox where the correspondence is stored and, for the form, Resend (an email delivery service, described below). I do not sell data or pass it to anyone for marketing.

05Contact form

The form on the contact page does not store data on the website or in any database. When you send it, the message is immediately delivered as an email to my mailbox through Resend (Resend, Inc., USA), which acts as a data processor. Data transfers outside the European Economic Area are based on the European Commission’s standard contractual clauses. The rules are described in Resend’s privacy policy.

To protect the form from spam, Cloudflare briefly checks your IP address (a limit of a few messages per minute from one address), and the form has a hidden trap field for bots. I do not store IP addresses and use no cookies or third-party scripts for this.

Providing data is voluntary, but without your name, email address and message I cannot reply. Instead of the form, you can also send a plain email.

06Bit, the AI assistant

Bit is the AI assistant in the corner of the website. It answers only from the content of this website. When you ask a question, its text (and a few previous messages from the same conversation) is sent to the Claude Haiku language model by Anthropic, PBC (USA), which prepares the answer. When that service is unavailable, the question goes to the Gemma model running on Cloudflare Workers AI (Cloudflare, Inc.), then may be passed to the DeepSeek model via OpenRouter, Inc. (USA; the model is run by DeepInfra, Inc.), and as a last resort to the Mercury model by Inception Labs, Inc. (USA); Anthropic and both backup providers do not use the questions for model training. All providers act as data processors; transfers outside the EEA are based on standard contractual clauses.

I do not store conversations with Bit or link them to you. The conversation exists only in the open browser tab and disappears when you close it. Please do not type personal data into the chat - use the form or email to get in touch.

I only keep anonymous statistics, to learn what people ask about and what is missing from the website: the language, the general topic of the question (e.g. price, industry, projects), whether Bit knew the answer and how long it took. They contain no question or answer text, no IP address and nothing that could identify you. Cloudflare stores them (Workers Analytics Engine) for about 3 months.

To protect Bit from bots and abuse, your browser solves a short computational task in the background with the first question, and Cloudflare briefly checks your IP address (a limit of questions per minute). The chat pass contains only a hash of the IP address and an expiry time (30 minutes). I do not store IP addresses and use no cookies or third-party scripts for this.

Bit’s answers are for information only: Bit can make mistakes, and its answers are not an offer in the legal sense nor a promise of any price, discount or deadline. Only the written quote I send before work starts is binding.

The "Prepare a request" path sends nothing: it only opens the contact form with the answers you chose. You send the message yourself, from the form.

07The "Does AI recommend your business?" tool

When you use the tool, the industry, city and business name you enter are sent to the Gemma model on Cloudflare Workers AI (to phrase the questions) and via OpenRouter, Inc. (USA) to the Gemini model (Google) with the Parallel Web Systems (USA) search engine, which prepare the answer. The data is used only for that one check. Transfers outside the EEA are based on standard contractual clauses.

I do not store what you enter or the results. To enforce the limit of 3 checks a day, Cloudflare KV keeps for about 25 hours a counter tied to a hash of your IP address (with a secret key, not the address itself) and a shared counter of all checks. Plus anonymous statistics: language, type of result, number of businesses named and response time, without names or cities, kept for about 3 months.

The result is for information only and shows AI answers from the day of the check. It is not a ranking or a rating of businesses.

08Your rights

You have the right to access your data, to have it corrected or erased, to restrict its processing, to data portability and to object. Just send an email. You also have the right to lodge a complaint with the President of the Personal Data Protection Office (PUODO) in Poland.

09Links to other websites

This website links to my projects and other services. Once you follow those links, their own privacy rules apply.

10AI-generated images

The photo of the desk on the home page was generated by AI in Google Flow. It does not show real people or places. The animations (including the S mark, the Earth and the spiral of sketches) are drawn with code, and the screenshots of my projects are real.
