Privacy notice
Last updated: 3 November 2026
Who is responsible for your data
This website is run by Marina Kontouli, sole trader, trading as Astron Global Management Services, Argalasti 37006, Greece (VAT no. EL132686992). I am the data controller for the personal data described here. You can contact me about anything in this notice at marina@astronglobalservices.com or +30 694 140 4780.
What I collect and why
| Data | Purpose | Legal basis (GDPR) |
|---|---|---|
| Name, email, company (optional), the service you choose and your message, sent through the contact form or by email | To reply to your enquiry and, if you ask, prepare a proposal or carry out a free check | Steps taken at your request before a contract (Art. 6(1)(b)) and my legitimate interest in answering enquiries (Art. 6(1)(f)) |
| Ads, scripts or documents you send for review | To carry out the review you asked for | Steps at your request / performance of a contract (Art. 6(1)(b)) |
| Client contact and billing details | To deliver services, invoice and keep accounting records | Contract (Art. 6(1)(b)) and legal obligation under Greek tax law (Art. 6(1)(c)) |
| Technical data such as IP address and browser type, recorded in the hosting provider’s server logs | To deliver the website securely and prevent abuse | Legitimate interest in running a secure website (Art. 6(1)(f)) |
Please don’t send customers’ personal data in material for review. If an ad or script contains personal data, remove it first or tell me so we can agree how it is handled.
Cookies and tracking
This website does not use analytics, advertising or tracking cookies, and it does not load fonts or scripts from third parties. Because of this, there is no cookie banner. If that changes, this notice will be updated and you will be asked for consent first.
Who receives your data
I don’t sell your data or share it for marketing. It is processed only by the service providers needed to run the website and email:
- Netlify, Inc. (USA): website hosting and contact form submissions.
- GoDaddy: domain and email hosting.
- My accountant, for client billing records, where required by law.
Where a provider processes data outside the European Economic Area, the transfer is covered by safeguards recognised under the GDPR, such as the EU–US Data Privacy Framework or the European Commission’s Standard Contractual Clauses.
How long I keep it
Enquiries that don’t lead to work are deleted within 24 months of our last contact. Material sent for review is deleted within 12 months of the review unless we agree otherwise. Client and invoicing records are kept for as long as Greek tax and accounting law requires.
Your rights
You can ask to access, correct or delete your data, to restrict or object to how it is used, and to receive it in a portable format. Email me and I’ll respond within one month. If you’re unhappy with how your data has been handled, you can complain to the Hellenic Data Protection Authority (www.dpa.gr) or the supervisory authority where you live or work.
Changes
If this notice changes, the new version will be published on this page with a new date.
