Privacy policy

1. Controller

Lucas Jesco Darian von Puttkamer, LLucid (sole proprietorship), Hedwigstraße 7a, 12159 Berlin, Germany. Email: lucas-x-business@protonmail.com.

2. Hosting and technical data

This website is operated on our own server in the EU. When you visit, technically necessary data such as IP address, time, page accessed and browser information are processed in order to deliver the site and ensure its security. The legal basis is Art. 6(1)(f) GDPR.

3. Fonts, images and local settings

Fonts, images and website code are loaded from our server. Your choice regarding website statistics is stored locally in your browser as "ls_consent". You can change it at any time via the cookie settings. We store your chosen animation setting as "ls_motion". Both settings are retained until you change them or delete the website data in your browser. These settings are not transmitted to us.

4. Optional website statistics

Google Analytics 4 is only loaded if you consent via the cookie settings. Without consent, no Analytics requests are triggered. The legal basis is your consent pursuant to Art. 6(1)(a) GDPR and, insofar as information is stored on or read from your device, § 25(1) TDDDG. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Data may be transferred to the USA in this process.

Among other things, page views and clicks on appointment booking are recorded. Ad personalisation and Google Signals are disabled in our implementation. With your consent, Google Analytics sets the cookies "_ga" and "_ga_4VY5YSW14K" (lifetime of up to 400 days, limited by the browser). Without consent they are not set, and if you withdraw consent we delete them. You can change your choice at any time: Open cookie settings. Withdrawal applies to the future.

5. Appointment booking and external links

Appointment booking is integrated as a link to Cal.com. The calendar service is not loaded automatically on this website. Only when you open the link do you switch to Cal.com. There, the Cal.com privacy policyapplies. The data entered for a booking are processed to organise your appointment.

The project websites shown are likewise only opened when you click their link. The respective privacy notices apply on those websites.

6. Contacting us

If you contact us by email, we process your details to handle your enquiry and, where applicable, to prepare a contract pursuant to Art. 6(1)(b) GDPR. For other enquiries, processing is based on our legitimate interest in handling them pursuant to Art. 6(1)(f) GDPR.

7. Contact form

If you use the contact form, we process your name, your email address, the selected topic, your message and the time of the enquiry in order to respond to it. The details are transmitted to our server in encrypted form and forwarded from there to us as an email. The email is delivered via Proton (Proton AG, Switzerland). Your message is not stored on the web server. To prevent abuse, the server briefly keeps a counter per visitor in memory, which contains only a truncated hash of your IP address. In addition, we receive a short notification with your name and the selected topic, but without the message text, on our mobile device via a messaging service (WhatsApp). The legal basis is Art. 6(1)(b) GDPR insofar as your enquiry relates to a contract, otherwise Art. 6(1)(f) GDPR. We delete your enquiry once it has been dealt with, provided no statutory retention periods apply.

8. Question field with AI assistant (CIPHER)

On the home page, you can ask the AI assistant CIPHER questions about our services. Use is voluntary; without it, you can reach us via the contact form or by email.

What data are processed: the text of your message and the previous chat history, the time and a truncated, irreversibly calculated hash of your IP address, which we need to prevent abuse (rate limiting per visitor). As with every visit to the website, an entry is also created in the server's access log with IP address, time and requested address, but without the content of your question; this log is deleted after 14 days. We do not permanently store messages or chat histories on our server. The conversation history remains in your browser's memory during your visit and is discarded when the page is reloaded. If you transfer a summary to the contact form and submit it, it is processed like your contact enquiry. For up to 24 hours, the service's memory holds a counter per visitor and a cache of answers to questions already asked, stored under a hash of the question, with no reference to you personally.

Recipients: To answer, we transmit your message and the previous chat history together with the text of this website to an AI service. The service used is that of Anthropic PBC (USA), or, if it fails, that of OpenAI (USA) as a fallback. The provider generates the answer and returns it to us. How long it retains inputs and for what purposes it may use them under its own terms is determined by the provider itself; we have no influence over this.

Transfer to the USA and consent: By submitting your question, you expressly consent to this transfer (Art. 6(1)(a) and Art. 49(1)(a) GDPR). The level of data protection in the USA may not correspond to that of the EU, for example because authorities may demand access to data and your rights may be harder to enforce there. You can withdraw your consent at any time with effect for the future by no longer using the question field or by writing to us; we cannot retrieve questions already transmitted to the provider. Please do not enter any personal data in your question.

Note on the answers: CIPHER is an AI assistant. The answers are generated automatically, may contain errors and are not binding; only what Lucas confirms to you is binding. No automated decision-making with legal effect takes place.

Optional voice input: If your browser supports the feature, you can dictate your request. Recognition only starts via "Start dictation" and after you grant microphone access. Depending on the browser, a speech service of the browser provider processes the audio. We only receive the recognised text when you send it in the chat. You can edit or discard it beforehand. Without voice input, you can still use the chat by typing.

9. Your rights

Subject to the statutory requirements, you have the right of access, rectification, erasure, restriction of processing, data portability and objection. You may withdraw any consent you have given with effect for the future. You may also lodge a complaint with a data protection supervisory authority.

For any matters concerning the processing of your data, please write to the email address given above.
