We try not to touch your data. When we do, this page tells you exactly what we touch, why, and what you can do about it.

We're the data controller for everything on this site — meaning we're the people responsible for the choices below. Email us with anything.
What we collect — and why
When you visit this page
We use Plausible Analytics (hosted in Germany) to count visits, track outbound link clicks, see which sections of the page people read and for how long, and count newsletter signups. Plausible doesn't use cookies and doesn't track you across sites. It briefly processes your IP address and browser type to work out whether you're a returning visitor that day, then discards both — we never see them and nothing is stored against you. The numbers we see are aggregated. You can read more in Plausible’s Data Policy.
Lawful basis: legitimate interest.
When you subscribe to the newsletter
If you click "Stay in the loop," we ask for your email. We send you a confirmation message — only after you click the link in that email do we add you to the list. That click is your consent.
We use Infomaniak Newsletter (a Swiss provider) to handle this. Infomaniak stores your email address, the date you subscribed, and the IP address you subscribed from — that combination is what European law requires us to keep as proof of your consent. See Infomaniak’s Privacy Policy.
We send occasional updates: what SeinX is up to, what we're building, what we're thinking.
Lawful basis: your consent.
It's optional — the rest of the site works the same either way. You can unsubscribe anytime — there's a link at the bottom of every email.
When you book a conversation
The "Book a call" button takes you to eu.cal.com — that's a separate service we use for scheduling. Once you click, you're on Cal.com's site under Cal.com's privacy policy. On our side, we only see the booking details Cal.com sends us (your name, email, the time slot, and anything you wrote in the booking notes).
When you email us
If you send a message to contact@seinx.ai, that email arrives at our Infomaniak Mail inbox (Switzerland). We read it, we reply, we keep the correspondence as long as the conversation is useful.
Lawful basis: legitimate interest in answering you.
Where your data lives
Everywhere we send your data, it stays in Europe or Switzerland:
- Infomaniak (newsletter, email, site hosting) — Switzerland.
- Plausible Analytics — Germany.
- OVH (DNS) — France.
Switzerland is covered by the EU's adequacy decision, meaning data there is treated under the same protections as inside the EU. We don't transfer anything to the US.
How long we keep it
| Newsletter subscription | Until you unsubscribe. |
| Plausible analytics | Aggregated only — no individual record kept on our side. |
| Server access logs | 30 days. |
| Email correspondence | As long as the conversation is alive — typically a few months, sometimes longer if it leads somewhere. |
Your rights
Under European law, you have the right to:
- See what data we hold about you.
- Correct it if it's wrong.
- Delete it (we'll do this unless we have a specific legal reason not to).
- Restrict how we use it.
- Take it with you in a portable format.
- Object to how we're using it.
- Withdraw consent for anything you previously consented to.
To exercise any of these, email contact@seinx.ai. We'll respond within 30 days — usually much faster.
Cookies
We don't use any. There's nothing on this site that reads or writes cookies, and nothing that asks us to.
No automated decisions
We don't make automated decisions about you, and we don't profile you.
Changes to this policy
If we change something here, we update the date at the top of the page. If the change is meaningful — new processor, new data, new purpose — we'll email subscribers about it before it takes effect.
Complaints
If you think we're handling your data badly and we haven't fixed it after you've told us, you have the right to complain to the Dutch data protection authority:
Autoriteit Persoonsgegevens (AP): https://www.autoriteitpersoonsgegevens.nl
We'd rather you talked to us first, but the right is yours.
