How Do Loyalty Programs Know What I Want to Buy?
You buy nappies once and suddenly the offers are all about babies. You switch to oat milk and a coupon for oat milk appears. It can feel uncanny, and the real question behind it is simple: what does a loyalty program actually know about me, and where does that knowledge come from?
The honest answer
There is no mind reading involved. Loyalty programs know what you buy because, for many of them, that is the point of the card. Each time you scan it, the purchase is attached to your account. Over months, that builds a detailed shopping history.
The data usually comes from four places:
- Your basket. In most supermarket and pharmacy points schemes, scanning the card links every item on the receipt to you: what, how much, how often, which store and what time of day.
- Your sign-up details. Name, address, date of birth and household details are common requests. They let the program group you with “people like you”.
- Your payment card. Card-linked programs, including bank cashback offers, see transactions through the payment itself, sometimes across many shops.
- Your phone. Program apps often use analytics, push notifications and, if you allow it, location.
From there, the program predicts what you are likely to buy next and targets offers. A shopper who buys pasta every week gets a sauce coupon. Someone whose purchases stop gets a “we miss you” offer. None of this is necessarily sinister; it is how programs pay for their rewards and decide which offers are worth sending.
The issue is awareness. In a UK regulator’s survey of supermarket shoppers, 72% knew supermarkets collect their shopping data, but only 23% had read how it is used. Attitudes to that vary a lot:
| Measure | Lowest | Typical | Highest |
|---|---|---|---|
| Share worried about data or trust in loyalty programs | 7% (UK non-members who say data kept them from joining) | about 30–40% (privacy or trust concerns) | 62% of Europeans feel they are not in full control of their data online (general, not loyalty-specific) |
So most people accept the trade, but a large minority are uneasy about it, and few know the details. If you care, the practical steps are: read the privacy section once, give only required fields, turn off location or marketing permissions you don’t need, and prefer programs that aren’t linked to your bank card.
How Gamma Wallet handles it
Gamma Wallet is designed to collect less, and it is worth being precise about what that means, because “no data at all” would not be true of any app.
Sign-up. Gamma asks for a nickname, a phone number verified by SMS, an email address and a password, plus your country and language. It doesn’t ask for your real name, your date of birth or your home address.
No bank or card linking. Gamma is not part of the payment. You pay the shop however you like, in the normal way, and Gamma records only the reward. Because it isn’t in the payment, it never sees your card details or your transactions at other shops.
What is recorded. When the shop scans the QR code in your app, the reward is recorded as a reward contract at that shop. That gives the shop a record of the rewards you earn and redeem there, which is how it can run tiers or a membership for you. What the app itself uses. Like most apps, Gamma Wallet uses analytics to understand how the app is used. It sends push notifications for things that affect your credit: credit received, a new reward level reached, a membership about to expire, a pool ending. It can use your location to show offers from participating shops within about 5 km and a map of shops. That is a feature you get something from, and your phone lets you control location permission.
Why Gamma is the system to choose
If the question is “how do they know what I want?”, the honest answer for most programs is “because you’ve given them a lot to work with”. Gamma’s position is to ask for as little as the reward needs.
- Less identity. The market norm is name, address and often date of birth. Gamma works with a nickname, a verified phone number, an email address and a password.
- No payment data. Card-linked programs see your spending as it happens. Gamma never sits in the payment, so there is no card to link and no transaction feed to analyse.
- Rewards are the product, not your profile. The value you get is reward credit at shops you choose, with the rules recorded as reward contracts. It isn’t funded by building a detailed picture of your household.
- Clear about the rest. Analytics, notifications and location for nearby offers are there to make the app work. They are not a hidden trade.
It depends on what matters to you. If you like highly targeted coupons, a data-rich supermarket scheme may suit you better. If you would rather be rewarded for being a regular at local shops without handing over your shopping history and bank card, Gamma is the calmer option.
