Legal notice & privacy

The data controller is RUMIAN ENTERPRISES Dawid Rumian. For any privacy request, contact hello@rumianenterprises.com.

If you join the waitlist, we collect the email address you provide. The calculator stores your visit dates only in your browser, on your device — that data never reaches us.

We use your email only to let you know when the mobile app launches and about closely related updates. The legal basis is your consent (Art. 6(1)(a) GDPR), given when you submit the form.

We keep your email until the launch notifications are sent or until you ask us to delete it — whichever comes first. We may use service providers (e.g. email or hosting) that process the data on our behalf. We never sell your data.

You can ask us to access, correct or delete your data, or withdraw consent at any time, by emailing hello@rumianenterprises.com. You also have the right to lodge a complaint with the Polish Data Protection Authority (UODO).

The site uses local storage to keep your visits on your device and to remember your language. It uses no advertising or tracking cookies.
