Privacy policy
Last updated: 28 July 2026
Who is responsible for your data
This site is run by Filip Piątek and Jakub Bilski, operating together as PB Devs from Poznań, Poland. PB Devs is not yet a registered company, so the two of us are the data controllers as individuals.
Any question about your data: support@pbdevs.com. A real person answers.
What we collect, and why
The contact form: your name, email address and the content of your message. We use them for one thing — to reply to you. The legal basis is Article 6(1)(b) GDPR (steps prior to entering a contract) or Article 6(1)(f) (our legitimate interest in answering people who write to us).
Traffic statistics: we run Umami, an analytics tool hosted on our own server, which counts page views and records the country, browser and device type, plus the site that linked you here. It writes no cookie and stores nothing in your browser; a visit is recognised by a one-way hash that is discarded daily and cannot be traced back to you. Legal basis: Article 6(1)(f) GDPR, our legitimate interest in knowing whether anyone reads this.
Analytics: if you agree to it, Google Analytics 4 records which pages are opened, roughly where in the world you are, and what kind of device you use. The legal basis is your consent — Article 6(1)(a) GDPR. If you don't agree, the script is never loaded and no analytics cookie is set.
Server logs: our hosting keeps standard technical logs (IP address, time, requested address) so we can find failures and abuse. Legal basis: Article 6(1)(f) GDPR.
Cookies
We set no marketing cookies and we sell nothing to ad networks.
One essential entry in your browser's local storage remembers your language and whether you agreed to analytics. It cannot identify you and it exists so the site doesn't ask again on every visit.
Analytics cookies (_ga, _ga_*) are set by Google Analytics only after you agree. You can withdraw that agreement at any time — clear this site's data in your browser and the banner returns.
Umami, our own traffic counter, sets no cookie at all. That is exactly why it runs without asking you first: it never reads or writes anything on your device.
Who else sees it
Hosting: Hetzner Online GmbH (servers in the EU) — the site and its database run there.
Email: messages from the contact form are delivered through pbdevs-mail, a service we built and run ourselves, which hands the message to an SMTP provider for final delivery.
Traffic statistics: nobody. Umami runs on our own server in the EU, so those numbers never leave our hands.
Analytics: Google Ireland Limited, only if you agreed. Google may transfer data outside the EU under the EU-US Data Privacy Framework.
We give your data to nobody else. We don't sell it and we don't use it to profile you or to advertise.
How long we keep it
Contact messages: as long as the conversation is live, and up to 24 months afterwards, so we can pick up a thread you left open. Ask and we delete them sooner.
Traffic statistics: aggregate counts kept indefinitely; the daily visitor hash they are built from is discarded every 24 hours.
Analytics data: 14 months, per the Google Analytics setting.
Server logs: up to 30 days.
Your rights
You can ask us for a copy of your data, to correct it, to delete it, to limit what we do with it, or to move it elsewhere. You can object to processing based on legitimate interest. Where we rely on consent, you can withdraw it at any time without giving a reason.
Write to support@pbdevs.com and we'll handle it within 30 days.
If you think we've mishandled your data, you can complain to the Polish data protection authority: Prezes Urzędu Ochrony Danych Osobowych, ul. Stawki 2, 00-193 Warszawa.
Changes
If this policy changes, the date at the top changes with it. The history of every version is public in the site's git repository.
