How the personal archive handles data.
Effective November 10, 2026
This notice describes the SimpliComfort Message Archive personal utility and this information website. The utility is operated locally by the person who installs it on their Mac and authorizes their Google account.
Data the utility accesses
- Local Messages data: message text, dates, sent/received direction, participant identifiers, available conversation identifiers, original status information and attachment records.
- Original attachment files: photos, videos, audio and other files already downloaded into that Mac’s Messages attachment storage.
- Google account information: the account email and Drive storage information used to check the destination during media authorization.
- App-created Drive data: the archive folder and files, their identifiers, links, sizes, checksums and upload status.
- The Gmail archive: mailbox status and archive Message-IDs used to verify copying and avoid duplicate retries.
Purpose and Google permissions
The data is used to create, verify and maintain the owner’s personal archive. The optional Google Drive OAuth connection requests https://www.googleapis.com/auth/drive.file. This limits Drive access to files the app creates or that the user explicitly makes available to the app through supported Google mechanisms; this implementation uses its app-created archive.
The utility does not request full-Drive access. Gmail uses a separate Google app password for IMAP access. That credential is authorized by the account owner; the utility’s implemented mail operations target the configured archive label.
Storage and credentials
Message transcripts and archive metadata are copied to the configured Gmail account. Original attachment copies are stored in the configured Google Drive account. The utility creates its Drive folder without adding public sharing permissions. The account owner can subsequently change sharing through Google’s controls.
OAuth refresh credentials and the Gmail app password are stored in the Mac login Keychain. Configuration, copying checkpoints, upload-session state, logs, previews and temporary database snapshots are kept in the Mac user’s local application-support storage. Mac backups may contain local archive-related files.
The downloaded Desktop OAuth client configuration remains wherever the owner saves it on their Mac. The owner should keep credentials and diagnostic output private.
Data sharing and AI services
The utility transfers archive data to Google services authorized by the owner. This information website does not receive message text, attachments or Google credentials. The utility does not sell data, use it for advertising or transmit it to a separate developer-operated archive server.
The owner may separately authorize ChatGPT’s Gmail and Google Drive connections. Information retrieved through those connections is handled under the owner’s applicable ChatGPT settings and the service’s terms. The Mac utility makes no OpenAI API calls and does not itself perform AI inference or model training.
Google API data is used for the personal archive functions described in this notice, consistent with the Google API Services User Data Policy and its Limited Use requirements.
Retention, deletion and revocation
Cloud archive copies remain until the account owner deletes them or Google’s account policies remove them. Deleting a source message or attachment does not automatically delete an archive copy. Pausing or removing the utility also leaves existing Gmail and Drive copies in place.
To stop copying, pause its Mac schedule. To remove the archive, delete the relevant archived Gmail messages and Drive files through Google’s account controls. To withdraw authorization, revoke the app’s Google account access and revoke the Gmail app password. Local program data and Keychain entries can be removed separately by the Mac account owner.
This information website
The site contains static information pages and no application sign-in, analytics or upload form. Its hosting provider may process routine web-request information such as IP address and browser details to deliver and protect the site. If a hosting access gate is enabled for a preview, the hosting provider handles that preview sign-in separately from the Mac utility.
Questions and updates
Contact the operator of your personal installation using the support email shown on the Google consent screen. Material changes to the utility’s data handling should be reflected in an updated notice before those changes are used.
