In the age of digital marketing, personalisation has become a cornerstone of effective communication. Businesses now use data to deliver tailored messages, recommendations, and offers that align with individual customer preferences. While this improves user engagement and business outcomes, it also raises critical concerns about data privacy. Today’s customers are more informed and cautious about how their data is collected and used. Therefore, marketers must carefully balance personalisation with ethical data practices to build and maintain consumer trust.
This article explores how businesses can navigate this balance, drawing from recent research, market trends, and practical strategies that respect privacy while delivering meaningful experiences.
The Power of Personalisation
Personalisation uses customer data to deliver content and services that match individual preferences. It ranges from customised product suggestions to personalised emails and dynamic website content.
A study by McKinsey & Company (2021) found that 71% of consumers expect personalisation, and 76% are frustrated when it is missing. Furthermore, companies that excel at personalisation can generate 40% more revenue from those activities than their counterparts.
These expectations are driven by platforms like Amazon, Netflix, and Spotify, which use advanced algorithms to recommend products, content, and services based on behaviour and preferences.
“Companies that grow faster drive 40% more of their revenue from personalisation than their slower-growing counterparts” (McKinsey & Company, 2021, para. 3).
However, to personalise effectively, companies need access to user data, which leads to increasing concerns over how that data is collected, stored, and shared.
The Rise of Privacy Awareness
Data privacy has become a priority for consumers globally. Data breaches, intrusive tracking practices, and misuse of personal information have made people more sceptical of how brands use their data.
According to Cisco’s 2022 Consumer Privacy Survey, 81% of global respondents said they believe the way a company treats their personal data is indicative of how they are treated as a customer (Cisco, 2022). Moreover, 86% of consumers said they care about data privacy, and 79% said they are willing to act on it by switching companies if their data is mishandled.
This shift in mindset has led to stronger privacy regulations worldwide, including:
- General Data Protection Regulation (GDPR) – EU
- California Consumer Privacy Act (CCPA) – USA
- Personal Data Protection Law (PDPL) – UAE
- Personal Data Protection Act (PDPA) – Singapore
These laws have reshaped how marketers collect and process data, with greater emphasis on transparency, consent, and user rights.
The Privacy–Personalisation Paradox
The privacy-personalisation paradox reflects the tension between offering relevant, personalised experiences and maintaining user privacy. Consumers want tailored services but are also concerned about surveillance and data misuse.
A PwC (2021) report found that 83% of consumers are willing to share their data for a personalised experience, yet 87% said they would not do so unless they trusted the company (PwC, 2021).
This highlights a simple truth: trust is the foundation of personalisation. Users may be comfortable sharing data if they believe the brand will use it responsibly.
Strategies to Balance Privacy with Personalisation
To meet both privacy requirements and personalisation goals, marketers must take a transparent, user-first approach. Below are proven strategies to strike this balance effectively.
1. Communicate Transparency
Being open about what data is collected, why it’s collected, and how it will be used is essential.
- Use clear and easy-to-read privacy policies
- Offer real-time explanations during data collection (e.g. pop-ups or tooltips)
- Avoid vague language like “We may use your data to improve services”
Tools such as TermsFeed and Iubenda help brands craft GDPR- and CCPA-compliant privacy policies.
2. Implement Consent Management
Modern consent tools give users the power to opt in or out of data collection. This ensures compliance and builds credibility.
- Display cookie banners with clear options
- Offer preference centres where users can update consent at any time
- Log and manage user choices transparently
Platforms like OneTrust and TrustArc provide scalable consent management systems.
3. Shift Toward First-Party and Zero-Party Data
As third-party cookies phase out, brands should prioritise data collected directly from users:
- First-party data comes from user interactions (e.g. website activity, purchases)
- Zero-party data is explicitly shared by users (e.g. surveys, preferences)
For example, beauty brand Sephora uses quizzes to collect zero-party data and deliver personalised recommendations without invading privacy (Salesforce, 2022).
Interactive platforms like Typeform and Jebbit help gather this data in engaging, permission-based ways.
4. Give Users Control
Privacy isn’t just about consent — it’s also about control. Companies should enable users to:
- Access their data
- Modify or delete personal information
- Download activity history
- Adjust communication preferences
Tech giants like Apple and Facebook allow users to manage their data through dedicated dashboards, reinforcing trust through transparency.
5. Minimise Data Collection
The principle of data minimisation means collecting only what’s needed for a specific purpose. It’s not only a GDPR requirement but also a smart practice.
- Don’t collect more data “just in case”
- Review and purge unused datasets
- Limit access to sensitive information within the company
This reduces the risk of data leaks and simplifies compliance.
6. Secure Data Handling
Once collected, data must be protected through:
- Encryption at rest and in transit
- Access controls and permission management
- Regular audits and compliance checks
IBM’s 2023 Cost of a Data Breach Report shows that the average data breach cost reached $4.45 million, highlighting the need for secure systems (IBM, 2023).
Cloud providers like AWS and Google Cloud offer robust security features for data management.
Case Studies: Brands That Got It Right
Apple: Privacy as a Core Value
Apple’s “Privacy. That’s iPhone.” campaign built its brand around user privacy. Features like App Tracking Transparency (ATT) gave users the choice to block tracking across apps, setting new industry standards.
Spotify: Transparent Personalisation
Spotify provides powerful personalisation through music recommendations. At the same time, it offers users access to data and ad preferences, explaining how recommendations are generated. Their clear privacy policy enhances user trust.
Sephora: Voluntary Data Collection
Instead of scraping user data, Sephora uses interactive quizzes to gather preferences. Customers willingly provide insights, and the brand uses that data to suggest products — a great example of ethical personalisation (Salesforce, 2022).
The Role of Technology
The shift towards privacy-first personalisation is supported by marketing tech (MarTech) tools that offer:
- Predictive analytics without storing raw data
- Federated learning to train AI without accessing personal records
- Synthetic data to simulate insights without real users
These innovations ensure personalisation continues without compromising privacy.
What Customers Expect Today
Modern consumers want:
- Personalisation that adds real value
- Transparent communication
- Data collection based on consent
- The ability to control their digital footprint
A Deloitte survey found that 73% of consumers are more likely to trust companies that are transparent about how their data is used (Deloitte, 2022).
The message is clear: brands that respect privacy can still win with personalisation — and even gain a competitive edge.
Note
Marketers no longer face a choice between personalisation and privacy — both are essential. By adopting privacy-by-design principles, collecting consent-based data, and giving users control and clarity, businesses can build long-lasting relationships based on trust.
In the end, the most personalised experience is one that feels safe, respectful, and honest. That’s the new gold standard in data-driven marketing.
