Last updated: 2025-10-08

1. Introduction

Welcome to Chamber.

These Terms of Use (“Terms”) govern your use of the Chamber software (“Software”), developed by Vaibhav Kaushal and others (collectively “Author”, or “Author(s)”). By using the Software, you agree to be bound by these Terms. If you do not agree, you must not use the Software.

2. Description of Service

Chamber is a client-side tool for creating encrypted file vaults (also referred to as “Chamberfile”) on your own device. User data is never uploaded to our servers unless specifically stated. The Software is cross-platform and may optionally connect to a server (“Backend”) for reporting telemetry data, account management and advertisements.

3. License & Usage Restrictions

Chamber is provided under a dual license:

• Open Source License: You may use Chamber for personal, non-commercial purposes under the GNU General Public License (version 3).
• Commercial Use: Any commercial usage of Chamber, including providing services to third parties, requires written permission.from the Author.

As such, you may not:

• Host Chamber as a service for others (e.g., SaaS) without permission.
• Resell, sublicense, or redistribute Chamber for commercial gain without permission.
• Use the Software in violation of applicable laws.

4. User Responsibilities

You are solely responsible for maintaining the integrity, confidentiality, and backup of your vault and any data inside it. You agree not to use the Software for illegal, harmful, or dangerous purposes.

5. Vault Identifier, Telemetry and display of Advertisements and Information

Each Vault (Chamberfile) contains a unique identifier called “Vault ID” which is used in conjunction with the user-provided password to create the key that is then used to encrypt user data. Another identifier called a “Vault Public ID” is generated completely out of the Vault ID by passing the Vault ID through a one-way hash function which makes it practically impossible to get the Vault ID from which it was derived. This Vault Public ID can be used to uniquely identify the Vault.

Telemetry APIs (as detailed in the Privacy Policy) use this Vault Public ID to identify the vault against which the telemetry data is sent to our servers. No vault contents or file data (including file names or their cryptographic hashes) are ever transmitted to us.

The Software may display advertisements or informational content fetched from our backend. These ads or content are not based on vault contents or file names.
