Your name, phone number, and — only if you choose to share it — your birthday. Also your stamp count, visit history, and the purchase amount when a staff member records one.
To run the loyalty card for the business you signed up with, and to push updates to that card in your wallet. Nothing else.
Only the business you signed up with. Stampi operates the platform on their behalf. We do not sell your data and we do not share it with third parties for their own marketing.
For as long as your card is active, and up to 12 months after it stops being used.
You can ask for a copy of your data or ask us to delete it. Deleting the card from your wallet stops updates immediately; contact the business or Stampi for full deletion.
Reach us at the business where you signed up, or through stampi.om.om.
