Who is the data controller
The data controller is Anna Grzelak, operating under the TERTIO brand. Contact: hello@tertio.studio.
What data we process
Only what you provide yourself when filling in the brief: your name, role, company name, photo, email address, phone number, website address and LinkedIn profile — to the extent you choose to share it.
Purpose and legal basis
We publish your data solely to create your digital business card (Card and Profile) — at your explicit request and with the consent you give when filling in the brief. Legal basis: Article 6(1)(a) GDPR.
The card is public
Your Card and Profile are public web pages — the data you put in them is visible to anyone who opens the link or scans the QR code. We never publish anything beyond what you provided in the brief.
How long we keep the data
Your data stays published until you ask us to change or remove it — there is no fixed retention period; you decide what changes and when.
Your rights
At any time you can ask to see, correct or delete your data, or withdraw your consent to its publication — write to hello@tertio.studio. Corrections and removals are handled as part of the update service.
Hosting
The site is hosted on Cloudflare infrastructure — the only party your data is technically entrusted to, solely to display your card. We do not use analytics or tracking cookies.
