Terms of Service

Last updated May 7, 2026

By installing or using the Harmonograph Chrome extension, you agree to these terms.

Use of the extension

Harmonograph is free to use. You may use it for personal or professional purposes. You may not reverse-engineer, redistribute, or sell the extension as your own.

Your credentials

Harmonograph requires a Linear Personal API key and Google Calendar access to function. You are responsible for keeping your API keys secure. Harmonograph stores these credentials locally on your device and does not transmit them to any external server.

No warranty

Harmonograph is provided "as is" without warranty of any kind. We make no guarantees about uptime, accuracy of data, or fitness for a particular purpose. Your use of the extension is at your own risk.

Third-party services

Harmonograph connects to Google Calendar and Linear on your behalf. Availability and accuracy of data from those services is outside our control. Your use of those services is subject to their own terms and conditions.

Changes

We may update these terms from time to time. Continued use of the extension after changes constitutes acceptance of the updated terms. The date at the top of this page reflects the most recent revision.

Termination

We reserve the right to discontinue the extension at any time without notice.
