Cookie & Local Storage Policy

Last Updated: August 4, 2026. This policy explains how Schema Flow Studio uses cookies, local storage, and IndexedDB to deliver a local-first, privacy-focused visual ERD experience.

1. Our Privacy-First Approach

Schema Flow Studio is built with a local-first database architectural model. We prioritize storing your visual ERD diagrams, Drizzle models, and application settings directly on your device rather than uploading them to unauthorized remote servers.

2. Storage Technologies We Use

Essential Local Storage

Used to save your active dark/light mode preference (schema-flow-theme) and cookie consent choices.

IndexedDB Storage

Stores your ERD tables, column definitions, relations, custom SQL snippets, and project AST schemas offline directly inside your browser.

Authentication Session Cookies

Secure HTTP-only cookies managed by Clerk authentication when signing into your optional cloud sync profile.

Zero Third-Party Trackers

We do not deploy third-party advertising cookies, cross-site tracking scripts, or commercial data collection algorithms.

3. How to Manage or Clear Your Cookies & Local Data

You can manage or clear your stored data at any time directly through your browser settings:

Browser Settings:Open your browser settings and navigate to Privacy & Security > Clear Browsing Data > Cookies and Site Data.
Workspace Project Export: Before clearing browser storage, export your projects to .schemaflow or SQL DDL files to prevent accidental data loss.
