Privacy Policy

Effective 22 September 2026 · Version 2026-09-22

1. Who we are and our role

Cornerstone Digital Agency, based in Accra, Ghana, operates the Cornerstone platform. For the personal data of our own users, including Merchants, savers, and the officers and users of Organisations, we decide how and why the data is used. For the personal data of a Merchant's Customers (people who pay a Merchant through Cornerstone) and of an Organisation's members and supporters, the Merchant or Organisation decides why it needs that data, and we handle it on its behalf to process payments and run the account. We also keep it ourselves for security, fraud prevention, and legal record-keeping.

2. What we collect

We collect only the data necessary to provide and secure our financial infrastructure.

All users

  • Name, phone number, and email address (where provided).
  • Ghana Card number, ID images, and a selfie (where provided for verification).
  • Transaction history on the Cornerstone platform.
  • Security data such as your PIN (stored only in hashed form), one-time codes, device and session information, and IP address.
  • Organisation name (for institutional accounts).

  • Your savings balances, goals, deposits, withdrawals, and any auto-save, auto-debit, or challenge settings.
  • The phone numbers you link to your account, and the payout numbers you register.
  • Details of the people and merchants you send money to or pay, such as their number, name, and amount.
  • Group savings membership and contributions, which the group's administrators can see.

  • Payout bank and Mobile Money account details, payout requests and approvals, and audit logs of who did what.

A Merchant's Customers

  • The Mobile Money number and network used to pay, the amount, the time, and the payment reference.
  • A name or email address where the Customer or Merchant provides it, and any data the Merchant chooses to attach to a payment.

3. Why we collect it

Your data is used strictly for the following operational purposes:

  • Operating the platform (processing payments, savings, settlements, and payouts).
  • Identity verification and AML/KYC regulatory compliance.
  • Preventing fraud and keeping accounts and funds secure.
  • Running your savings, transfers, recurring payments, and group features.
  • Showing Merchants and Organisations who has paid them, and giving them reports, receipts, and insights.
  • Verifying Organisations and their officers, and approving payouts under our Maker-Checker controls.
  • Building your verifiable financial record.
  • Qualifying Merchants and savers for credit pathways via our MFI and lender partners, where you apply.
  • Sending you service messages, such as receipts, codes, and security alerts.
  • Fixing errors, monitoring performance, and improving the platform.

4. Merchants, Organisations, and the people they serve

Merchants receive information about payments made to them, such as the payer's phone number, amount, and time. Merchants must use this only to run their business, keep it secure, and meet their legal duties. If a Merchant sends SMS messages to its Customers through Cornerstone, the Merchant is responsible for having the right to contact them and for what the messages say. Merchants who connect their own systems through the Collect API or webhooks are responsible for protecting the data they receive there.

Organisations can see the information about their members, supporters, and payers that is needed to run their accounts, such as who paid, how much, and when. They must have the right to give us the data they upload, use what they receive only for their own legitimate activities, and protect it. Organisations that message their members through Cornerstone are responsible for having the right to contact them.

If you are a Customer, member, or supporter and have a question about how a Merchant or Organisation uses your data, contact them first. You can also contact us and we will help.

5. Who we share data with

We share data only where needed to run the service, and only with:

  • Mobile network operators, USSD aggregators, and payment and banking partners, to carry out transactions.
  • Banks, lender, MFI, and other partners, but only when you apply for or take one of their products, and only what is needed for that application. For a savings product this includes the identity details the provider needs to open your account.
  • Other members and administrators of a savings group you join, who can see the group's membership and contributions.
  • Service providers that help us run Cornerstone, such as SMS and messaging, identity verification, cloud hosting, file storage, error monitoring, and analytics, under strict instructions to protect the data. Some may process data outside Ghana; where they do, we require appropriate safeguards.
  • The Merchant or Organisation you pay or belong to, as described in Section 4.
  • Regulators, law enforcement, and courts, where the law requires it or to protect against fraud.

6. What we never do

  • We do not sell your data to any third party.
  • We do not share your data with unauthorised third parties.
  • We do not use political affiliation data for non-political purposes.

7. Political data

Data collected for political branches (e.g., constituency dues, delegate registers) is ring-fenced. It is never shared with external parties and is not used for any purpose beyond the specific membership management function for which it was collected.

8. How long we keep data

We keep data for as long as your account is active and afterwards for as long as the law requires us to keep financial, identity, and transaction records, or as needed to resolve disputes and prevent fraud. When we no longer need it, we delete it or anonymise it.

9. Your rights

You have the right to access, correct, delete (subject to legal retention requirements), and object to the processing of your data at any time. Merchants can also ask for a copy of their account and transaction records. To exercise these rights, contact us at info@mycornerstonegh.com. We may need to verify your identity first.

10. Data security

Your data is protected using enterprise-grade security. Data at rest is encrypted using AES-256. Data in transit is secured via TLS protocols. Access is strictly audited and limited to authorised personnel. No system is perfectly secure, so please protect your PIN, passwords, one-time codes, and API keys.

11. Age

Cornerstone is for people aged 18 and over. We do not knowingly collect data from children.

12. Changes to this policy

We may update this policy. The version number and effective date at the top of this page show the current version. For material changes, we will give notice through the app, dashboard, SMS, or this website.

13. Governing law

This Privacy Policy is governed by the provisions of the Data Protection Act, 2012 (Act 843) of the Republic of Ghana.
