Schelio — Privacy Policy

Last updated: April 4, 2026

Summary: Schelio does not collect, store, transmit, or share any user data. Everything stays in your browser.

What is Schelio?

Schelio is a Chrome extension that provides an interactive Entity Relationship Diagram (ERD) viewer for Salesforce. It connects to your Salesforce org using your existing browser session to display metadata about your objects, fields, and relationships.

Data Collection

Schelio does not collect any data. Specifically:

No personal information is collected
No usage analytics or telemetry
No tracking pixels or third-party scripts
No cookies are created by Schelio
No data is sent to any external server

Salesforce Session

Schelio reads your Salesforce session cookie (sid) from your browser to authenticate API calls to your Salesforce org. This session token is:

Used only to make API calls directly to your Salesforce org
Never stored, persisted, or transmitted to any third party
Never logged or recorded
Discarded when you close the tab

Data Storage

Schelio uses your browser's localStorage to save:

Your ERD layout (object positions, zoom level, selected objects) — per org
Your theme preference (dark/light)

This data is stored locally on your machine only. It is never transmitted anywhere. You can clear it at any time via your browser settings.

Permissions

Schelio requests the following Chrome permissions:

activeTab — to detect when you are on a Salesforce page
cookies — to read the Salesforce session cookie for API authentication
Host permissions (*.salesforce.com, *.force.com, *.salesforce-setup.com) — to make REST API calls to your Salesforce org

Third-Party Services

Schelio does not use any third-party services, libraries, or APIs other than the Salesforce REST API (which connects directly to your own org).

Open Source

Schelio is open-source under the MIT License. You can review the complete source code at github.com/zmissoum/Schelio.
