This Privacy Policy explains how Gossner Electronics & Embedded Systems GmbH ("we", "us") handles personal data when you visit gpibee.com (the "Website"). We take your privacy seriously and collect as little data as possible.
The data controller responsible for this website is:
Gossner Electronics & Embedded Systems GmbH
Gruenberger Str. 5
47506 Neukirchen-Vluyn, Germany
E-Mail: kai@gossner.dev
For the full legal notice see our Impressum.
When you visit this Website your browser automatically transmits the following data to our web server (or hosting provider):
This data is technically necessary to deliver the website to you and is processed on the legal basis of Art. 6(1)(f) GDPR (legitimate interest in operating a secure, functional website). Log files are retained for 30 days and then deleted automatically.
The product page contains an interactive 3D model rendered by the open-source model-viewer library. This library is served directly from our own server — no external CDN is contacted when you load the 3D model. No additional personal data is processed.
If you contact us by e-mail, we process the data you send (name, e-mail address, message content) solely to handle your request. The legal basis is Art. 6(1)(b) GDPR (processing necessary to respond to your enquiry) or Art. 6(1)(f) GDPR (legitimate interest in customer communication). Data is deleted once your enquiry has been fully resolved and no statutory retention periods apply.
On the firmware page you can voluntarily sign up to be notified by e-mail when a new firmware version is released. If you do, we store:
The legal basis for this processing is your consent (Art. 6(1)(a) GDPR), given by submitting the form. No confirmation e-mail is sent automatically when you subscribe or unsubscribe — the form shows a confirmation directly on the page instead. Firmware announcements themselves are also not sent automatically by this website; we compose and send them manually. Your address is used solely for this purpose and is never shared with third parties or used for any other kind of marketing.
You can unsubscribe at any time, either via the one-click link included with any e-mail you receive, or directly on the firmware page by entering your e-mail address and clicking "Unsubscribe". Unsubscribing permanently and immediately deletes your e-mail address from our system — there is no retained or "soft-deleted" record. As long as you remain subscribed, your address is kept until you unsubscribe; there is no separate automatic expiry.
To prevent the signup form from being used to check whether a particular address is already subscribed, a repeat submission of the same address only shows "already subscribed" to the same browser session that originally subscribed it (see section 3, Cookies); anyone else submitting that address receives a generic confirmation with no change to our records. To prevent automated bulk signups/unsubscribes, submissions are additionally rate-limited by IP address: our server briefly and temporarily notes the requesting IP address together with a timestamp purely to enforce this limit. This rate-limit data is kept for a short period (a few hours) and then automatically discarded; it is never linked to the e-mail addresses stored above. The legal basis for this is Art. 6(1)(f) GDPR (legitimate interest in preventing abuse of the signup form).
This website does not use any advertising, tracking, or analytics cookies.
The firmware-update signup/unsubscribe form (see section 2.4) sets one technical, first-party session cookie (PHPSESSID) when you use it. It contains no personal data itself — it's a random session identifier used only to remember, for the duration of your browser session, which e-mail addresses you have just subscribed, so that a repeat submission can show you an accurate "already subscribed" message without revealing that information to anyone else. This cookie is not set anywhere else on the website, is not used for tracking or analytics, and expires automatically when you close your browser. As it is strictly necessary for this feature to function, no separate consent banner is shown for it (§ 25(2) No. 2 TTDSG / Art. 6(1)(f) GDPR).
We do not sell, trade, or otherwise transfer your personal data to third parties. Data is only shared where strictly required by law or to operate the website (e.g. our hosting provider, acting as a data processor under a Data Processing Agreement).
Our hosting provider is: variomedia AG, Germany. variomedia AG acts as a data processor under a Data Processing Agreement in accordance with Art. 28 GDPR.
All assets (HTML, CSS, JavaScript, 3D model) are served from our own server located in Germany. No personal data is transferred to third countries (outside the EU/EEA) in connection with visiting this website.
Under the GDPR you have the following rights regarding your personal data:
To exercise any of these rights, contact us at: kai@gossner.dev
You also have the right to lodge a complaint with a supervisory authority. The competent supervisory authority for North Rhine-Westphalia is:
