Privacy and data security

Local-first accounting needs clear data boundaries.

Mekazu is designed around local administrations on Mac. This page explains what that means for accounting data, AI model access, cookies, newsletter preferences, MCP, REST API access, backups, and the responsibilities that remain with the user.

Short answer

Mekazu keeps the core accounting administration local on the Mac. External AI providers are used only when the user connects them with their own account and API key.

Local accounting data

The core bookkeeping workflow is built around a local Mac administration. Mekazu does not need a cloud mirror of the administration for invoices, purchases, VAT, reports, bank activity, and exports.

AI provider boundaries

Mekazu does not include paid access to OpenAI, Claude, Mistral, or other external model providers. If you connect an external provider, you do that with your own account and API key. Local models can be used through Ollama where supported.

Cookies and newsletter preferences

Google Analytics is loaded only after analytics cookies are accepted. Newsletter preferences are stored separately from cookie consent in the local website database until a production email provider is connected.

MCP and REST API access

MCP and REST API access can expose accounting context to tools, scripts, or compatible AI clients. These workflows require a license after the 14-day AI trial and should be enabled only for trusted local workflows.

User responsibilities

Users remain responsible for Mac security, backups, operating system updates, provider accounts, API keys, and deciding which data may be sent to connected model providers.

Checklist
