How to delete your Mambu account

About deleting your Mambu account

Mambu is a highly specialized, cloud-native core banking and financial services platform designed for banks, lenders, and fintech innovators. Unlike retail banking apps, Mambu acts as a backend engine that manages complex financial products, customer ledgers, and transaction processing. Because the platform stores sensitive financial records and personally identifiable information (PII) for millions of end-customers, closing an account is not a simple automated toggle.

Organizations often seek to delete their Mambu environment due to contract expiration, a transition to a different core banking system, or corporate restructuring. When an organization decides to discontinue its use of Mambu, the process must be carefully managed to ensure compliance with financial regulations like GDPR, CCPA, or local banking data retention mandates. Key reasons for deletion include:

• Migrating core ledger data to an on-premise or competing cloud infrastructure.
• Terminating a pilot program or "sandbox" environment that held real-world test data.
• Reducing the attack surface by purging inactive instances containing sensitive API keys and connection strings.

What happens to your data

Mambu acts as a data processor for its clients, meaning it retains data based on the specific service agreements established at the start of the contract. When you request an account deletion, Mambu typically transitions the account into a "decommissioning" phase. Types of data processed by Mambu include:

• Detailed transaction histories and ledger entries.
• Customer demographic and credit profile data.
• API configuration logs and system access credentials.
• Custom configuration files and integrations with third-party payment gateways.

While Mambu will purge the active tenant data upon a verified request, they are often legally obligated by financial regulatory bodies to maintain certain audit logs and system snapshots for specific periods. You should confirm with your Mambu representative exactly which archival data will be permanently destroyed versus what remains in cold storage for regulatory compliance.

Privacy considerations

Because Mambu handles high-stakes financial data, its privacy model is distinct from social or consumer platforms. The primary concern is not ad targeting, but rather the secure handling of sensitive financial records that could be exploited if left in a dormant, insecure environment. Consider the following when offboarding:

• Ensure all API keys connected to your Mambu instance are revoked before requesting deletion to prevent unauthorized access during the offboarding window.
• Verify that your team has exported all necessary ledger data and historical reports, as recovery after the decommissioning process is usually impossible.
• Confirm whether your Mambu instance was integrated with third-party marketplaces; these connections must be severed manually to prevent data leakage from the third-party providers.

Frequently Asked Questions

Can I delete my Mambu account through the web portal?

No. Mambu does not provide a self-service deletion portal because of the complex nature of its banking architecture.

Who do I contact to initiate data deletion?

You must contact your assigned Mambu Customer Success Manager or the official Mambu Enterprise Support team to submit a formal request.

Is my data deleted immediately upon request?

No. Mambu follows standard enterprise decommissioning protocols which include a verification period and technical purging cycles.

What happens to the end-users of my banking app if I delete my Mambu instance?

All services dependent on the Mambu engine will cease to function, and data associated with those end-users will become inaccessible or purged depending on your configuration.

Does Mambu keep backups after I delete my account?

Due to strict financial regulations, Mambu may retain system logs or audit-ready backups for a mandated period, though your active tenant data will be removed from production environments.

How do I ensure all my sensitive data is gone?

You should request a written certificate of data destruction from your Mambu representative once the decommissioning process is complete.
