# Privacy Policy

Last updated: 12 May 2026

## 1\. Data Controller

**Pro Digital Key** Rua Professor Doutor Egas Moniz, 100 3860-078 Avanca · Estarreja · Aveiro · Portugal NIF: PT226673219 Email: [dpo@prodigitalkey.com](mailto:dpo@prodigitalkey.com) Phone: +351 928 268 011

## 2\. Data Collected

We collect personal data voluntarily provided through the forms on our website, including:

-   ✓ Full name
-   ✓ Email address
-   ✓ Phone number
-   ✓ Company name
-   ✓ Business information shared voluntarily

**Contacts that reach us by phone or WhatsApp** — if you call us or send a WhatsApp message, we record what is needed to answer you: your name, the number you called from, the company and the matter you raised. The number is kept because it is often the only way we can reach you again. The lawful basis is taking steps at your request prior to entering into a contract (Art. 6(1)(b) GDPR), since you approached us. These records are deleted with your erasure request (Art. 17) — which you may make giving only the phone number, if you never gave an email — and are included in your access request (Art. 15).

We do not collect payment data directly — these are handled by certified payment processors (Stripe, etc.).

## 3\. Purpose of Data Processing

Your data is used exclusively to:

-   ✓ Respond to contact and diagnostic requests
-   ✓ Send requested commercial proposals
-   ✓ Newsletter (only with explicit consent)
-   ✓ Compliance with legal obligations

We do not sell, rent or share your data with third parties for commercial purposes.

## 4\. Legal Basis

The processing of your data is based on your explicit consent (Art. 6(1)(a) of the GDPR) and/or on the legitimate interest of Pro Digital Key in providing the requested services (Art. 6(1)(f) of the GDPR).

## 5\. Data Retention Period

We keep data only for as long as each purpose requires, then delete or anonymise it automatically. The main periods are:

-   ✓ **Website usage statistics** — 13 months
-   ✓ **Contact and proposal requests** — up to 5 years, after which they are anonymised
-   ✓ **Meeting bookings** — 24 months
-   ✓ **Chat conversations** — 90 days after closure
-   ✓ **Newsletter** — while you remain subscribed; after unsubscribing we keep only proof of consent
-   ✓ **Commercial relationship (CRM)** — for as long as the relationship lasts; interaction history is pruned after 12 months
-   ✓ **Security and audit logs** — anonymised at 24 months, deleted at 48 months

You may request erasure of your data at any time (section 6), without waiting for these periods.

## 6\. Your Rights (GDPR)

You have the right to:

-   ✓ **Access** — know what data we hold about you
-   ✓ **Rectification** — correct inaccurate data
-   ✓ **Erasure** — request deletion of your data ("right to be forgotten")
-   ✓ **Objection** — object to processing for marketing purposes
-   ✓ **Portability** — receive your data in a machine-readable format
-   ✓ **Lodge a complaint** — with the CNPD (Comissão Nacional de Proteção de Dados — Portuguese Data Protection Authority)

To exercise these rights, contact: [dpo@prodigitalkey.com](mailto:dpo@prodigitalkey.com)

## 7\. Cookies

Our website uses essential technical cookies required for the page to function. We do not use third-party tracking cookies for advertising purposes without your consent.

## 8\. Data Security

We apply appropriate technical and organisational measures to protect your personal data against unauthorised access, loss or destruction, including HTTPS encryption and restricted access controls.

## 9\. Changes to This Policy

We reserve the right to update this policy. Significant changes will be communicated by email to our clients. The date of the last update is indicated at the top of this page.

## 10\. Sub-processors and International Transfers

In order to deliver our services, Pro Digital Key engages specialised sub-processors — third parties that process personal data on our behalf and under our instructions, pursuant to data processing agreements (DPAs) entered into under **Article 28 of the GDPR**. Where processing involves the transfer of personal data outside the European Economic Area (EEA), we rely on one of the safeguards set out in **Chapter V of the GDPR (Articles 44 to 49)**: a European Commission adequacy decision, the Standard Contractual Clauses (SCCs — Decision 2021/914), or, where applicable, the _EU-US Data Privacy Framework_ (DPF).

Current list of sub-processors that may process your data:

-   ✓ **Anthropic, PBC** — Content analysis and generation via the Claude API (newsletter authoring assistance). Location: _United States_. Transfer basis: SCCs + EU-US DPF.
-   ✓ **Twilio Inc.** — Transactional SMS and WhatsApp delivery (incl. appointment reminders). Location: _United States_. Transfer basis: SCCs + DPA + EU-US DPF.
-   ✓ **Google Ireland Limited (Google Calendar / Meet)** — Scheduling of meetings and generation of video-call links for booked appointments. Location: _Ireland (EU/EEA)_, with possible processing in the United States. Transfer basis: SCCs + EU-US DPF.
-   ✓ **Meta Platforms Ireland Limited (WhatsApp Business)** — WhatsApp appointment reminders, where that channel is enabled. Location: _Ireland (EU/EEA)_, with possible processing in the United States. Transfer basis: SCCs + EU-US DPF.
-   ✓ **Amazon Web Services EMEA SARL** — Transactional email delivery (SES). Location: _Ireland (EU/EEA)_. Transfer basis: not applicable (within the EEA).
-   ✓ **Emailit LTD** — Email _fallback_ delivery. Location: _United Kingdom_. Transfer basis: EU–UK adequacy decision (2021).
-   ✓ **Google Ireland Limited (Google Workspace)** — Business mailbox and commercial communications. Location: _Ireland (EU/EEA)_, with possible processing by group entities in the United States. Transfer basis: SCCs + EU-US DPF.
-   ✓ **Contabo GmbH** — Application server hosting (VPS). Location: _Germany (EU/EEA)_. Transfer basis: not applicable.
-   ✓ **pCloud AG** — Encrypted off-site backups. Location: _Switzerland_. Transfer basis: Adequacy Decision 2000/518/EC.
-   ✓ **Google Ireland Limited (Google Drive)** — Encrypted off-site backups (secondary destination). Location: _Ireland (EU/EEA)_, with possible processing in the United States. Transfer basis: SCCs + EU-US DPF.
-   ✓ **Amazon Web Services EMEA SARL (S3)** — Encrypted off-site backups (tertiary destination). Location: _Ireland (EU/EEA)_. Transfer basis: not applicable.

In addition, we use components that do **not** qualify as external sub-processors because they do not involve the transfer of personal data to third parties: the _MaxMind GeoLite2_ database, which is downloaded and queried locally on our servers (no data is sent back to MaxMind), and the _GlitchTip_ error-monitoring system, hosted on our own infrastructure.

Under **Article 13(1)(f) of the GDPR**, you have the right to be informed of these international transfers and, upon request, to obtain a copy of the safeguards in place. You may also exercise the right of objection under **Article 21 of the GDPR** in relation to processing by a specific sub-processor by contacting us at [dpo@prodigitalkey.com](mailto:dpo@prodigitalkey.com).

The list of sub-processors may be updated as our infrastructure evolves. We undertake to notify material changes by email to data subjects with an active relationship with us, with at least 14 days' notice, allowing the right of objection to be exercised before the change takes effect.

## 11\. AI Chat Assistant

When you interact with our chat assistant in the bottom-right corner of the site, we collect and process the following data:

-   ✓ **Exchanged messages** — text you type in the chat and the responses generated by the bot or sent by an operator.
-   ✓ **Profile data shared voluntarily** — name, email, phone, company when you provide them in the conversation.
-   ✓ **Technical metadata** — IP address, user-agent, source page, detected language, anonymous session identifier (UUID).

**Automatic detection and masking of sensitive data**: the system scans for patterns such as IBAN, credit-card numbers (with Luhn validation), tax IDs, ID cards, and API keys; when detected, they are replaced with markers before the conversation is stored. This masking is defensive — it may fail for atypical cases. We recommend you do not share sensitive data in the chat.

**Legal basis**: processing is based on Pro Digital Key's _legitimate interest_ in providing support to website visitors (Art. 6(1)(f) GDPR). When the assistant explicitly asks you to leave an email for follow-up, the processing then relies on your _consent_ (Art. 6(1)(a)).

**Retention**: conversation transcripts are automatically deleted **90 days** after closure. You may request immediate erasure at any time via [dpo@prodigitalkey.com](mailto:dpo@prodigitalkey.com) or by exercising the rights described in section 6.

**Chat-specific sub-processors**:

-   ✓ **Ollama Inc.** — bot response generation via open models hosted in a European region (eu-frankfurt). Location: _EU/EEA_. Transfer basis: not applicable.
-   ✓ **Anthropic, PBC** — _fallback_ when the primary model is unavailable. Location: _United States_. Transfer basis: SCCs + EU-US DPF.

Messages sent to the chat are transmitted in real time to one of these processors to generate the reply. **No processor uses chat content to train its own models** — this commitment is contractually secured in the respective DPAs.

**Chat-specific rights**: you can download a full transcript of your conversation at any time via the «Save conversation» button in the chat-widget header. To delete all past conversations associated with your email, exercise the right to erasure.

## 12\. Audience Measurement (Traffic Analytics)

We use our own, self-hosted statistics system to understand how this website is used. By default it runs in **anonymous, cookieless mode**: we do not store your IP address (only your country, derived from a truncated address), we do not identify you individually, and we do not track you across visits. The lawful basis is our _legitimate interest_ (Art. 6(1)(f) GDPR) in measuring and improving the site's performance. The data is retained for at most **13 months** and is never shared with third parties. You may object at any time via [dpo@prodigitalkey.com](mailto:dpo@prodigitalkey.com).

**Returning-visitor recognition (optional, consent only)** — If you allow it in our cookie notice, we store an identifier in your browser to recognise repeat visits and improve your experience. This feature relies on your _consent_ (Art. 6(1)(a) GDPR and Art. 5 of Portuguese Law 41/2004) and can be withdrawn at any time, without affecting your access to the site.

**Linking your browsing history to your contact record** — If, having consented to returning-visitor recognition above, you send us a form, the pages you visited on this site become associated with the contact record created from that form — including visits made _after_ you submitted it, and those made from other devices where you gave the same consent. We use this to understand what matters to you before we get in touch. The lawful basis is our _legitimate interest_ (Art. 6(1)(f) GDPR) in preparing and tailoring the commercial contact you asked us for, balanced against your reasonable expectations — and it depends on the consent you gave for the identifier, which you may withdraw at any time. **Without that consent, no browsing history is linked to you.** This data is retained for at most **13 months**, is deleted when you exercise your right to erasure (Art. 17), and is included in your subject access request (Art. 15). You may object to this linking, without losing access to the site or to a reply to your enquiry, via [dpo@prodigitalkey.com](mailto:dpo@prodigitalkey.com).

## 13\. Company Identification (Business Visitors)

When a visit comes from a company network, we may identify the **organisation** (never the individual) from the IP address, by matching it against commercial business-intelligence databases, for B2B marketing and sales analysis. **We do not identify individuals.** Visits from residential or carrier networks are discarded. The lawful basis is our _legitimate interest_ (Art. 6(1)(f) GDPR). You may object to this identification or request your organisation's exclusion via [dpo@prodigitalkey.com](mailto:dpo@prodigitalkey.com).

## 14\. Third-Party Tags (Analytics and Advertising)

In addition to the self-hosted system described in section 12, we may use third-party tools to measure audience and campaign performance. **All of them start switched off**, and none is enabled without being declared here. Those that depend on consent are **not loaded at all** — not even downloaded to your browser — until you give it.

**Google Tag Manager** (Google Ireland Ltd.) — a technical container that manages the other tags. It collects no data of its own. Lawful basis: _legitimate interest_ (Art. 6(1)(f) GDPR).

**Google Analytics 4** (Google Ireland Ltd.) — usage statistics. Without your consent it runs in _Consent Mode_: no cookies and no identifiers. Lawful basis: _legitimate interest_ in cookieless mode; _consent_ (Art. 6(1)(a)) for full measurement — **Analytics** category.

**Microsoft Clarity** (Microsoft Ireland Operations Ltd.) — **session recording** and heatmaps: it records mouse movement, clicks and page scrolling. It never runs without your consent. Lawful basis: _consent_ — **Analytics** category.

**Meta Pixel** (Meta Platforms Ireland Ltd.) — conversion measurement and remarketing for Facebook and Instagram campaigns. Lawful basis: _consent_ — **Marketing** category.

**TikTok Pixel** (TikTok Technology Ltd., Ireland) — conversion measurement and remarketing for TikTok campaigns. Lawful basis: _consent_ — **Marketing** category.

**Microsoft UET** (Microsoft Ireland Operations Ltd.) — conversion measurement and remarketing for Microsoft Advertising (Bing) campaigns. Lawful basis: _consent_ — **Marketing** category.

**Transfers to third countries** — The **TikTok Pixel** involves processing of personal data by TikTok group entities located outside the European Economic Area, including in **China**. Those transfers rely on the European Commission's Standard Contractual Clauses and on supplementary measures declared by the controller. The remaining tools may transfer data to the United States under the _EU-U.S. Data Privacy Framework_. If you do not wish your data to be transferred on those terms, do not grant _Marketing_ consent.

You may withdraw or change your consent at any time via the **«Cookie preferences»** button in the bottom-left corner of any page. Withdrawal prevents these tools from loading in future; any already loaded on the current page stop loading from the next page load onwards.
