Data Protection
Privacy Policy
We take the protection of your personal data very seriously. This privacy policy informs you about the nature, scope, and purpose of the processing of personal data on this website in accordance with the General Data Protection Regulation (GDPR) and the Austrian Data Protection Act (DSG).
1. Controller
The controller responsible for data processing on this website is:
Martin Mueller
Canettistrasse 1
1100 Vienna, Austria
Email: office@greyscale.at
2. Data We Collect
We collect and process the following categories of personal data:
- Account data: name, email address, and profile image when you create an account or sign in via a third-party provider (Google, Microsoft, or Apple).
- Project data: information you provide about your jewelry commission, including descriptions, design preferences, and reference images you upload.
- Design conversations: the text, notes, and sketches you share during the brief intake with our AI design assistant (see section 5).
- Technical data: technical information your browser transmits when you visit the site (such as IP address, browser type, and time of access), processed in server logs and operational monitoring to keep the service secure and reliable (see section 7).
- Communication data: content of messages you send us via email or our contact channels.
3. Legal Bases for Processing
We process your personal data on the following legal bases under Art. 6(1) GDPR:
- Consent (Art. 6(1)(a)): for optional marketing communications you have signed up for. You may withdraw your consent at any time.
- Contract performance (Art. 6(1)(b)): for processing account and project data necessary to provide our bespoke jewelry design services.
- Legitimate interests (Art. 6(1)(f)): for website security, fraud prevention, and improving our services.
4. Third-Party Sign-In
You may sign in using your Google, Microsoft, or Apple account. When you do, the respective provider shares your name, email address, and profile picture with us. We store this data solely to authenticate your session and personalise your experience. We do not receive or store your password from these providers.
The data processing by these providers is governed by their own privacy policies:
5. Hosting and AI-Assisted Design Intake
Your account, project, and conversation data — along with any files or images you upload — are stored on EU-based cloud infrastructure operated within the European Economic Area. This data is not transferred outside the EU for routine hosting.
AI-Assisted Design Intake
During the brief intake, you may have a guided conversation with our AI design assistant. To generate the assistant's replies, the text of your conversation is sent to Anthropic, PBC ("Anthropic"), an AI service provider based in the United States. Anthropic processes this content only to produce the assistant's responses and does not use it to train its models.
This transfer to a third country is safeguarded by the EU Standard Contractual Clauses (SCCs) included in our data processing agreement with Anthropic. For more information, see Anthropic's Privacy Policy.
Once an equivalent EU-based AI service becomes available, we intend to migrate this processing to it.
6. Cookies
This website uses only its own first-party cookies — small text files stored on your device — for core functionality. We do not use analytics cookies or third-party tracking cookies.
- Strictly necessary cookies: required for authentication and session management. These do not require your consent.
- Recognition cookie: set only when you share your email address with us — for example to reserve a piece or book a visit. It stores that email address in signed form so this device can be shown your reservations and booked visits without a login. It expires after 120 days and is never shared with third parties.
You can manage or delete cookies at any time through your browser settings. Disabling strictly necessary cookies may impair website functionality.
7. No Web Analytics or Tracking
This website currently uses no web analytics services, tracking pixels, or advertising technologies. We do not build profiles of your browsing behaviour, and no visitor data is shared with analytics or advertising providers.
Our servers record technical operational data (see section 2) solely to keep the service secure and reliable. Should we introduce an analytics solution in the future, we will update this policy first and, where required, ask for your consent.
8. Data Retention
We retain your personal data only for as long as necessary to fulfil the purposes described in this policy, or as required by law. Specifically:
- Account and project data are retained for the duration of the customer relationship and for seven years thereafter, in accordance with Austrian statutory retention obligations (§ 132 BAO).
- The recognition cookie (see section 6) expires automatically after 120 days at the latest.
- You may request deletion of your account and associated data at any time (see section 9).
9. Your Rights
Under the GDPR, you have the following rights with respect to your personal data:
- Right of access (Art. 15) — obtain confirmation of whether we process your data and request a copy.
- Right to rectification (Art. 16) — request correction of inaccurate data.
- Right to erasure (Art. 17) — request deletion of your data, subject to legal retention obligations.
- Right to restriction of processing (Art. 18) — request that processing be limited under certain conditions.
- Right to data portability (Art. 20) — receive your data in a structured, machine-readable format.
- Right to object (Art. 21) — object to processing based on legitimate interests.
To exercise any of these rights, contact us at office@greyscale.at. We will respond within one month.
