Shoppers in 2026 want the best of both worlds: a store that knows their size, their taste, and the right moment to show a coat they'll actually wear — but without feeling watched. That tension now has a name inside retail research: the privacy paradox. The instinct isn't new, but the numbers this year are sharper than they were twelve months ago.
The new data deal: value before trust
For years, the working theory was simple. Earn a shopper's trust, and she'd hand over her data. In 2026 that order has flipped. According to Drapers' Connected Consumer 2026 research, the leading reason shoppers now share personal information is a tangible payoff — 31% cite offers and discounts as their top motivator, up from a trust-led model a year earlier. Trust in the brand, which drove 49% of sharing decisions in 2025, has fallen to 29%. Shoppers are no longer relying on reputation alone; they're weighing the immediate value they get back.
That doesn't mean they've gone cold on personalization. Attentive's 2026 survey of 1,050 shoppers across the US, UK and Australia found 93% are more likely to keep shopping with a brand that personalizes the experience, and 73% are more likely to buy when recommendations match their needs. The appetite is there. The price they'll pay in data is just lower than it used to be.
What shoppers will — and won't — hand over
Drapers' year-over-year data tells the story in plain numbers. Email, still the most accepted data point, is now shared by 47% of consumers, down from 56% in 2025. The drop is steeper for basic identifiers: willingness to share a name fell from 62% to 36%, age from 46% to 29%, and home address from 41% to 29%. Even measurements such as waist size slipped from 47% to 36%. Shoppers aren't rejecting data sharing outright — they're narrowing the aperture.
There's a clear exception, and it matters for apparel. Behavioural signals are gaining ground. The share of consumers willing to share style preferences rose from 13% to 23%, and those open to answering questions about their shopping habits nearly doubled, from 10% to 19%. In other words, shoppers will tell you what they like far more readily than who they are. For a fashion brand, that's the signal: earn taste data, not identity data.
The personalization they actually want
Not all personalization lands the same. Attentive found 64% of shoppers say brand messages are too generic, and 80% are likely to ignore brands that send irrelevant ones. The personalization that works is specific: the right size in stock, a restock alert on a saved item, a recommendation that fits the cart. Showing products available in the shopper's size rose from 19% to 24% as a reason to share data; product recommendations sat at 20%, basket reminders and wish lists at 17% each.
Generational splits reinforce the pattern. Gen X remains most open to traditional data points — 56% will share email versus 46% of millennials and just 37% of Gen Z. Younger shoppers, by contrast, are more comfortable with digital-native signals such as social handles. The takeaway for a brand: one data strategy doesn't fit every cohort.
How brands earn the trade
The path back to trust is transparency, not more prompts. Qualtrics' 2026 Global Consumer Experience Trends report found 86% of shoppers would share data if organizations were "more transparent and clear about its usage." Only 39% currently believe the benefits of personalization are worth the privacy cost. Just 16% are comfortable with brands listening to or watching them through devices to build a profile. Coveo's 2026 research adds that 75% of shoppers are "very cautious" about sharing personal data, yet 82% still log in to retailer sites — 45% at the start of browsing, 37% at checkout. They want the experience; they want it on their terms.
For an independent fashion label, the practical move is first-party data collected with consent: a size quiz, a saved favourites list, an email sign-up that clearly states what it unlocks. Salesforce's State of the Connected Customer reports 86% of consumers are concerned about data privacy yet 64% will share data for a better experience. The gap between those two figures is the entire job — close it with clarity, not coercion.
At PHEFEE we build for this reality. Inclusive sizing from XS to 3XL, exact inch measurements on every product page, and a new-in edit that learns from what you save rather than what you surrender. Personalization that respects the paradox.
Frequently asked questions
What is the privacy paradox in shopping?
The privacy paradox is the gap between wanting personalized, relevant shopping and being reluctant to share the personal data that powers it. Shoppers expect brands to know their size and taste, but they've grown cautious about who holds their information.
Are shoppers sharing less data in 2026?
Yes. Drapers' Connected Consumer 2026 research shows declines across nearly every category year over year — email sharing fell from 56% to 47%, name from 62% to 36%, and address from 41% to 29%. Behavioural signals like style preferences are the one area rising.
What makes shoppers willing to share data?
Tangible value. In 2026, offers and discounts are the top motivator (31%), overtaking brand trust (29%). Shoppers also respond to size-appropriate recommendations, restock alerts, and transparent explanations of how their data improves the experience.
How can brands personalize without feeling invasive?
Collect first-party data with consent — size quizzes, saved items, clear email opt-ins — and show exactly how it improves the experience. Qualtrics found 86% would share more if usage were transparent, and 46% want clearer control including deletion rights.
