Data Privacy: Growth strategy for fintech (Not just a compliance burden)

By Paulette WATSON (MBE)

Ghana’s fintech winners won’t just be the fastest, they’ll be the most trusted. With AI profiling, cross-border cloud and rising breach costs, privacy is becoming a growth lever, not a legal tax.

Accra’s fintech story has always been a story of speed: faster onboarding, faster payments, faster credit decisions. But the next stage of growth will be won on trust, the kind that survives scams, social media storms, partner scrutiny and regulatory questions.

That trust increasingly comes down to one customer question: what are you doing with my data?

This is not a niche concern. Ghana’s mobile money ecosystem now serves about 23.4 million active customers, which makes data practices a national business issue, not a back-office policy issue. And when trust breaks, the damage is not abstract: IBM estimates the average global cost of a data breach is US$4.88 million, and US$6.08 million in the financial industry.

For years, many fintechs treated privacy like a compliance burden, something to patch in after shipping the product. That framing is now expensive. In a market where customer acquisition costs are rising, the companies that retain customers will win, and retention is deeply linked to whether people believe your platform respects them.

The trust economy: privacy drives adoption and retention

In fintech, trust is a conversion metric. When customers abandon onboarding after being asked for a Ghana Card scan, a selfie, and permissions they don’t understand, the problem is not always “friction”. Often it is fear: fear of scams, tracking, data resale or exposure.

Privacy strengthens trust in three practical ways:

1. It reduces surprise. Outrage is often about “I didn’t expect that,” not about “you collected data.”
2. It makes the product feel safe. People notice minimised permissions and clear explanations.
3. It protects loyalty under stress. In outages or fraud spikes, customers stay if they believe you are competent and transparent.

A fintech CEO put it this way (illustrative):

“When we improved our data explanations and removed unnecessary permissions, we saw fewer drop-offs. Privacy became a growth KPI.”

The new risk stack: AI profiling, vendors, and cross-border cloud

The privacy risk used to be the database. Today, the risk is the ecosystem—models, vendors, and distributed infrastructure.

AI and “profiling” (plain English)

Profiling means using data to predict something about a person: fraud likelihood, ability to repay, what offer to show, what limit to give. It’s common in fraud and credit products. It becomes risky when it is opaque, excessive, or unfair, mainly when models rely on proxies that customers never expected.

A cybersecurity and AI risk leader warns (illustrative):

“The biggest privacy risk is no longer the database. It’s the model, because models can create hidden decisions and hidden harms.”

Third parties quietly expand the risk surface.

Fintech stacks rely on KYC/identity vendors, analytics tools, cloud platforms, customer messaging tools, fraud engines and AI providers. Each vendor adds another set of people, systems and subcontractors that may touch customer data. Customers will still blame the fintech when something goes wrong.

“Where is my data?” becomes a real diligence question

Cross-border cloud architectures make basic governance harder: where data is stored, who can access it, what happens on termination, and what deletion really means across backups and logs. This is no longer a technical debate; it is now a partnership and investor diligence issue.

The cost of getting it wrong: reputation, revenue, regulation

When privacy fails, the damage compounds:

• Churn and stalled adoption: onboarding drop-offs, merchants pause integrations, customers migrate quietly.
• Support overload: complaints and escalations spike; teams lose weeks to firefighting.
• Partner risk: banks and telcos tighten requirements or suspend relationships.
• Regulatory exposure: Ghana’s Data Protection Act, 2012 (Act 843), and the Data Protection Commission set the legal baseline for the handling of personal data.
• Valuation impact: weak governance becomes a negotiating point in funding rounds and M&A.

The breach-cost benchmarks underscore why boards should care: the average breach cost globally is US$4.88 m, and in the financial industry it is US$6.08m, according to IBM. That’s before counting long-term trust erosion.

A data protection/legal expert note (illustrative):

“Privacy failures trigger a chain reaction, complaints, audits, partner concerns, and loss of confidence. The cheapest fix is before scale.”

Privacy-by-design: competitive advantage, not paperwork

Privacy-by-design means privacy is built into product decisions and operating processes from the start.

Product moves that protect growth:

• Collect less by default: if you don’t need contacts or location, don’t ask for them.
• Explain permissions at the moment of use: simple language, clear purpose.
• Give users control: opt-outs where appropriate, and clear ways to access or delete data.

Operational moves that build confidence:

• Name an accountable owner (executive-level).
• Train product, marketing and support, not just compliance.
• Prepare an incident response that includes customer communication.

DPIA, explained simply

A DPIA (Data Protection Impact Assessment) is a structured way to ask: “What could go wrong for people if we launch this feature, and how do we reduce harm?” It’s beneficial for AI scoring, behavioural analytics, and new high-risk vendors.

Vendor risk: what to demand from AI/cloud providers

If a vendor mishandles data, customers won’t separate the vendor from you: contracts and oversight matter.

Minimum demands (contracts practice):

• Clear roles (who decides purpose vs who processes).
• No vendor reuse of your customer data for their own purposes.
• Sub-processor transparency (who else touches data).
• Fast breach notification timelines.
• Audit rights (proof, not promises).
• Verified deletion and strong termination clauses.

Practical playbook: 10-point checklist for Ghanaian fintechs

1. Map data flows end-to-end.
2. Minimise collection and permissions.
3. Make consent meaningful and understandable.
4. Run DPIAs for high-impact features (especially AI).
5. Tighten access controls and logging.
6. Reduce linkability (separate identity from behaviour where possible).
7. Maintain a tested incident response plan.
8. Treat AI models as high-risk assets (monitor, document, review).
9. Strengthen vendor governance (contracts reviews).
10. Turn privacy into a customer promise.

CEO checklist (60 seconds)

• Do we know every vendor that touches customer data?
• Can we explain where data is stored and who can access it?
• Are we collecting anything we don’t truly need?
• Do we run DPIAs for AI scoring and significant changes?
• Do we have a tested breach response plan and a customer comms playbook?

Questions to ask your AI vendor

• Will you use our data to train your models, yes or no?
• Who are your sub-processors, and where are they?
• What deletion guarantees exist across backups/logs?
• What audit evidence can you provide?
• How do you detect and mitigate bias?

What customers should expect

• Minimal data collection and clear explanations
• Real choices and controls
• Honest communication if something goes wrong
• Respectful handling of personal information

Conclusion: privacy as valuation protection and growth fuel

Ghana’s fintech market is scaling at national levels, 23.4 million active mobile money customers is proof of the ecosystem’s reach. In that environment, privacy is no longer a compliance footnote. It is part of customer experience, partner confidence and brand durability. And with breach costs benchmarked at US$4.88m globally and US$6.08m in the financial industry, weak data governance is also an existential business risk.

Call to action (CTA — investors):

Investors should treat privacy maturity like financial controls: require evidence of vendor governance, incident readiness, and data minimisation before writing the cheque, including a current data flow map, high-risk vendor terms (audit and sub-processor controls), and a tested breach response plan.
