AI Transparency
Last updated: April 2026
This page explains how artificial intelligence tools are used in the development and maintenance of CalGhost, and makes clear what role — if any — AI plays in the handling of your data.
🔒 No AI model ever processes, accesses, stores, or transmits your calendar data. AI is a development tool only — it is completely absent from the runtime pipeline that handles your information.
How CalGhost uses AI
CalGhost uses Claude by Anthropic as a development tool. Claude assists with writing and maintaining the codebase — reviewing logic, generating code, and helping with documentation.
Claude operates exclusively during development, on our developer machines, with no access to production systems or any user data.
What AI does NOT do
- AI does not process your Google Calendar data at any point.
- AI is not part of the sync pipeline. Calendar events are read from and written to Google Calendar directly by standard server-side code using the Google Calendar API — no AI intermediary.
- AI does not have access to your OAuth tokens, event times, event titles, or any other personal information.
- AI is not used to analyze, summarize, or act on your data in any way.
- Your data is never sent to an AI model — not to train models, not to improve AI systems, not for any purpose.
The sync pipeline is AI-free
When CalGhost syncs your calendars, here is exactly what happens:
- Our server reads event times from your personal Google Calendar using the Google Calendar API (
calendar.readonlyscope). - Our server creates, updates, or deletes anonymous "Busy" blocks on your work Google Calendar using the Google Calendar API (
calendar.eventsscope). - This data flows only between your browser, our server, and Google's servers — via encrypted HTTPS connections.
Claude (or any other AI service) is not involved in any of these steps at runtime.
AI services used in development
The following AI tool is used exclusively during the development of CalGhost:
- Claude by Anthropic — used as a coding assistant to write and review application code. Claude does not have access to production infrastructure, user data, or any live system. More information: anthropic.com
No AI training on your data
CalGhost does not use your Google Calendar data to train, fine-tune, or improve any AI or machine learning model — ours or anyone else's. This is also stated in our Privacy Policy.
