If you have a visitor account, the two you are most likely to want are built into the product rather than reserved for an email exchange: you can change your password and delete your account outright from your account page, without asking anyone. Deletion is immediate and is not a request we review.
Deleting your account removes your name, your email address, your password, every note you wrote, and every session and pending link belonging to you. It does not delete the measurements your reports produced — the record that a person saw one crowd level while a camera published another, and when. Those rows are separated from you permanently: the link to your account is severed, your notes are erased, and what remains identifies nobody. We keep them because they are facts about a piece of hardware rather than about you, and because the camera-accuracy figures we publish are built from them; letting one deletion silently move a number the public is invited to check would make that number worthless. If you disagree with that reasoning, write to us — and the supervisory authorities named at the end of this section are open to you regardless of what we say.
More generally, you may ask for a copy of the personal data we hold about you, ask us to correct it, ask us to delete it, ask us to restrict or stop a particular use, object to processing based on legitimate interest, and ask for your data in a portable form. Write to contact@ystara.com and we will answer within one month.
Requests are free. We will ask enough to be sure it is your data you are asking about, and nothing more.
If you are unhappy with how we handle it, you may complain to a supervisory authority: Gegevensbeschermingsautoriteit / Autorité de protection des données — gegevensbeschermingsautoriteit.be (Belgium); Commission Nationale de contrôle de la protection des Données à caractère Personnel (CNDP) — cndp.ma (Morocco).
