Read only
The planned owner-only pilot would use Yahoo IMAP with only the separately approved mail-r read scope to inspect Inbox and Junk/Spam. It would not request mail-w, CardDAV, or CalDAV.
Pre-launch
A read-only watchdog for consequential email
J.SCEW is a product in development intended to help its owner notice potentially consequential Yahoo messages, including messages from unfamiliar senders and messages in Junk/Spam.
Not available yet. J.SCEW has no public service, public beta, pricing, provider approval, OAuth credential, or connected mailbox. This site does not enroll users or request mailbox access.
Planned first-version boundary
No mailbox actions
It is not designed to send, reply, forward, move, delete, mark messages read, create rules, open links, load remote images, or separately open or decode attachments.
Contained interpretation
Email content is treated as untrusted data, not as authority. Classification output cannot authorize tools or broaden mailbox permissions.
Planned data boundary
- Reusable mailbox credentials stay outside prompts, model context, project files, ordinary logs, screenshots, support artifacts, and alerts.
- Only bounded message data needed for classification is processed. A raw MIME body fetched through IMAP can contain encoded attachment parts; those bytes may therefore pass through bounded transient memory even though attachments are not separately opened or decoded.
- Raw message bodies, including any encoded MIME attachment parts they contain, are not retained by default; temporary content is intended to be discarded after a decision.
- Operational records are limited to items such as nonreversible message identifiers, timestamps, provider checkpoints, reason codes, and alert state.
- A user-controlled provider revocation path is required before any live use.
Important limits
J.SCEW is not a spam filter, an autonomous security system, a guarantee that important mail will be detected, or a replacement for provider security and human judgment. Reliability and live-provider behavior have not been established. The current implementation has been tested offline with synthetic data and local fakes only.
