This Privacy Policy explains how we collect, use, and protect personal data when you visit hydralab.gr (the "Site"). We are committed to protecting your privacy and complying with the EU General Data Protection Regulation (GDPR), the Greek Law 4624/2019, and the ePrivacy Directive.

1. Who we are (Data Controller)

• Website: https://hydralab.gr

For any questions about this Privacy Policy or to exercise your rights, please contact us at info@hydralab.gr.

2. What data we collect

We collect personal data only when you actively provide it to us. Specifically:

2.1 Contact form data

When you submit our contact form at /contact, we collect:

• Name — to address you in our reply
• Email address — to respond to your inquiry
• Message content — the details of your project or question

We do not require you to create an account, and we do not collect any other personal data through forms.

2.2 Technical data (automatically collected)

When you visit our Site, our hosting provider (Vercel) automatically processes basic technical data necessary to deliver the website to you:

• IP address (used transiently for routing and security; not stored by us)
• Browser type and version
• Operating system
• Date and time of access
• Referring page

This data is processed by Vercel as part of standard web infrastructure operations and is not used by us for tracking or profiling.

2.3 Usage analytics (anonymous)

We use Vercel Analytics to understand which pages are visited and how the Site performs. Vercel Analytics is cookieless and uses anonymized, hashed identifiers stored in your browser's session storage. It does not collect personal data, IP addresses in identifiable form, or cross-site tracking information. The data is aggregated and used solely for improving the Site.

2.4 Language preference

If you change the website language between Greek and English, we save your choice in your browser's local storage under the key hydralab.locale. This is strictly functional and does not identify you.

3. Why we use your data (Legal basis)

We process personal data on the following legal bases under Article 6 GDPR:

4. Who we share your data with (Recipients)

We do not sell, rent, or trade your personal data. We share data only with the following service providers ("data processors") who help us operate the Site:

All processors operate under Data Processing Agreements (DPAs) compliant with Article 28 GDPR. Transfers to the USA rely on the EU-US Data Privacy Framework and/or Standard Contractual Clauses as appropriate safeguards under Article 46 GDPR.

We do not share your data with advertisers, analytics networks, or third parties for marketing purposes.

5. International data transfers

Some of our processors (Vercel, Resend, Cloudflare) are based in the USA. When your data is transferred outside the European Economic Area (EEA), it is protected by:

• The EU-US Data Privacy Framework certification of the processor (where applicable), or
• Standard Contractual Clauses approved by the European Commission, and
• Additional technical and organizational safeguards (encryption in transit and at rest).

6. How long we keep your data

• Contact form messages: retained in our email inbox for as long as necessary to address your inquiry, and typically deleted within 24 months unless an ongoing business relationship requires longer retention.
• Technical/server logs: retained by our hosting provider for short periods (typically 30 days) for security and debugging purposes.
• Vercel Analytics data: anonymous, retained according to Vercel's policies (typically up to 12 months).
• Language preference (local storage): stored in your browser until you clear it.

7. Your rights under GDPR

You have the following rights regarding your personal data:

• Right of access (Art. 15) — to obtain a copy of the data we hold about you
• Right to rectification (Art. 16) — to correct inaccurate data
• Right to erasure (Art. 17) — to request deletion of your data ("right to be forgotten")

We take reasonable technical and organizational measures to protect your data, including:

• HTTPS encryption (TLS) for all traffic
• Server-side validation and origin checks on form submissions

• Limited access to data on a need-to-know basis

No method of transmission over the internet is 100% secure, but we work to apply industry-standard protections.
