What Damga does with your number
You gave a shop your phone number so your stamps can find you again. This is everything that happens to it, in the order it happens.
What we hold
Your mobile number. A name, if you give one. An email address, if you give one at the counter: it is kept only so your card appears when you sign in to the Damga app with it, nothing is ever sent to it, and it is deleted once it has done that. The stamps and rewards each shop has recorded for you, with the date, the time and which member of staff made each entry. Nothing else: no address, no payment details, no location, and nothing about what you bought.
Why
To show your cards to you and to the shop stamping them, and to settle it if you and a shop ever disagree about what you earned. That is the whole purpose. We do not sell your data, we do not advertise to you, and no shop is told about your cards at any other shop.
Where it is held
On servers in Doha. Requests reach them through an edge network that terminates the connection outside Qatar. The app itself is cached there, the same as any website: the screens, and the code behind them. Nothing carrying your name, your number or your cards is. Every one of those responses is marked never to be stored, and that is enforced in the code rather than left to configuration.
Who sees it
Staff at a shop you have visited see your name, your balance there, and that shop's own entries. They read your name back to you at the till so you can tell they stamped the right card. Searching for you before you are identified shows them only a partial name. They cannot see your other cards. Damga staff can see records when investigating a dispute or a fault, and that access is logged.
Having it deleted
From Settings in the Damga app, or by emailing hello@damga.qa. Your account and your identifying details go, along with the link between you and every card you hold. What stays is the stamp and reward history with nobody's name on it, because a shop's own record of what it gave away is its accounts and it cannot be un-given. Our backups are kept for 30 days in Qatar, so a deletion is fully worked through them within 30 days.
Reaching a person
hello@damga.qa. A person reads it.
