Mumm protects your account, documents and negotiation records with access controls tied to your role and authorization. Your agreement and Privacy Policy describe the commitments that apply.

## Access follows your account and role

Access to accounts, documents and negotiations is restricted by account ownership, role and authorization.

## You control what sellers receive

Your housing shortlist and private scenarios remain separate from the request you authorize. A merchant handoff uses an explicit brief for the selected business. It does not give that business access to your private planning thread or unrelated requests.

## Share the documents needed for the request

Documents are linked to your request and accessible to authorized participants and service staff. Our Privacy Policy and Data Handling page describe how information is used and your available choices.

## Actions stay within your authorization

Mumm acts within your authorization and records seller offers and customer approvals separately from drafts and suggestions.

## Payment status is explicit

Your request shows the payment instructions and the status of payment and delivery alongside the agreed offer.

## Review what happened

You can review messages, offers and actions recorded within Mumm. External agents’ private reasoning and undisclosed limits remain private.

## Security assurance

Contact us for security documentation and to discuss the audit, certification or regulated-data requirements for your organization.

## Report a security issue

Use the contact page to reach the Mumm team about a security concern. Do not include passwords, payment credentials or unrelated personal records in your first message.
