Privacy Policy — Hermes Ness OS

Hermes Ness OS is a private personal productivity assistant intended for the exclusive use of its owner.

Google user data accessed

Depending on the permissions granted by the user, Hermes Ness OS may access information made available through Google Workspace APIs, including Gmail messages and metadata, Google Calendar events, Google Drive files and metadata, Google Docs, Google Sheets, and Google Contacts information.

How Google user data is used

Google user data is accessed and processed solely to perform functionality requested by the authorized user. This may include summarizing or locating emails, preparing or sending messages, reviewing calendar events, organizing files, reading or updating documents and spreadsheets, locating contacts, and executing other personal productivity workflows initiated by the user.

Google user data is not used for advertising, retargeting, credit assessment, data brokerage, or the training of general-purpose artificial-intelligence or machine-learning models.

Storage

OAuth credentials and certain information required to operate Hermes Ness OS may be stored on the private server used to operate the assistant.

Information retrieved from Google services may also be temporarily or persistently stored when required to complete a user-requested workflow, maintain user-created records, or provide continuity for the assistant.

Sharing and disclosure

Hermes Ness OS does not sell Google user data.

Google user data is not transferred or disclosed to third parties except where technically necessary to provide functionality explicitly requested by the authorized user, or where required by law.

Security

Reasonable technical and organizational measures are used to restrict access to the server, credentials and information used by Hermes Ness OS. Access is limited to the owner and authorized technical systems required to operate the application.

Data retention and deletion

Data is retained only for as long as reasonably necessary to provide the requested functionality or maintain records intentionally created by the user.

The owner may delete stored information, revoke Hermes Ness OS access to their Google Account, or delete the application's stored OAuth credentials at any time. Google authorization may also be revoked through the user's Google Account security settings.

Changes to this policy

This Privacy Policy may be updated if the application's functionality or use of Google user data changes. The current version will remain available at this URL.
