We use it to decide whether to work with you. Nothing else.
Only what the form asks, which is:
Applications are kept in our own systems and read by the people who decide on applications. We do not sell them, and we do not pass them to anyone outside the company.
If we work together, for as long as we do. If we do not, six months, then it is deleted. We keep unsuccessful applications that long for one reason: people reapply, and it is quicker for both of us if we can see what you told us the first time.
Write to us on the channel you gave us and say so. No form, no reason needed. If you no longer have that channel, use hello@ugchir.ing.
You can also ask for a copy of what we hold, or ask us to correct it. Same route, same answer time as everything else.
