Overview
What MailBridge does
MailBridge works locally with Outlook Classic. It makes approved Outlook information available in a user-selected filesystem location so that a user-chosen AI assistant or other approved tool can help search, analyse and draft a reply. MailBridge can then create a reply draft in Outlook Classic.
MailBridge does not operate a remote email server, a hosted AI model or a MailBridge cloud service.
Information
Personal information accessed and why
MailBridge accesses the following information only as needed for functions the user authorizes:
- Outlook message content and metadata: message body text, subject, sender and recipient details, date, conversation information, message identifiers, sensitivity/protection state and attachment metadata. This supports approved export, search, analysis, triage, reply drafting, threading and safety checks.
- Outlook account and routing information: the configured account address, Outlook profile/store/folder information, approved signature information and local Outlook item locators. This lets MailBridge keep work within the correct mailbox, preserve Outlook's recipients and conversation, and place the draft in the correct Drafts folder.
- Approved attachment content: attachment bytes are made available only after local approval and validation when that content is needed for a user-authorized task.
- Operational information: configuration, opaque identifiers, capability material, hashes, indexes, checkpoints, journals, status, error codes and bounded work counts. This supports security, integrity, recovery, deduplication and diagnostics.
MailBridge refuses protected or incomplete message content for drafting. It does not use personal information for advertising and does not sell personal information.
Storage and protection
Where information is stored
User-selected storage
The user chooses MailBridge's filesystem storage root. Message snapshots, message metadata, user-authorized AI work records and approved attachment files are stored there. The location may be inside a Dropbox folder.
If the user chooses Dropbox-backed storage, the Dropbox desktop software may sync the MailBridge folder through the user's own Dropbox account. That processing is controlled by the user and is subject to Dropbox's terms and privacy policy. MailBridge does not use the Dropbox cloud API.
Local operational state
MailBridge keeps operational state under the current user's local Windows profile. This is limited to configuration, protected Outlook routing state, DPAPI-protected capability keys and journals, hashes, indexes, checkpoints, retry state and content-free logs. Local logs contain operational identifiers, states, durations, error codes and bounded counts—not email subjects, bodies, senders, recipients or attachment filenames.
Safeguards
MailBridge uses the current Windows user's filesystem permissions, Windows Data Protection API protection for local secrets and sensitive operational state, opaque mailbox identifiers, mailbox-scoped capabilities, immutable records and strict routing and draft verification. A storage root's per-mailbox folders provide logical separation; they are not a substitute for access controls. The user is responsible for securing the Windows account, Outlook profile, selected storage location, Dropbox account and any external AI account they choose.
Services you choose
When third parties may process information
MailBridge itself does not upload personal information to Sergey Alexeev or a MailBridge-operated server. The current product contains no MailBridge analytics or telemetry.
Information may nevertheless be processed by these categories of third party through services the user has selected:
- Microsoft and the user's mailbox provider continue to process Outlook mailbox data under the account and service the user already uses. MailBridge's local Outlook integration does not replace those arrangements.
- Dropbox or another storage/sync provider may process files if the user puts the MailBridge storage root in that provider's synced location.
- An external AI service or AI-enabled tool may process the MailBridge data that the user intentionally makes available to it for analysis or drafting.
Each selected service operates under its own terms and privacy policy. Users should review those terms and only make mailbox information available to a service they are permitted and willing to use.
Generative AI
AI-assisted output requires review
MailBridge is designed for AI-assisted analysis and drafting. The current product does not itself provide a hosted generative-AI model; the user chooses whether to use an external AI service or AI-enabled tool.

Retention and controls
Your choices
MailBridge's bounded mirror copies normally expire 90 days after the source message's received or sent date, although records needed for pending work may be retained until that work is resolved. Disposable search requests and results normally expire after seven days. Approved staged attachments normally expire after 24 hours or when the dependent request completes, whichever comes first.
The user controls MailBridge and can:
- choose the storage location and stop using or remove that location;
- disable MailBridge to stop its background processing;
- choose whether to use any external AI service or AI-enabled tool;
- delete MailBridge files from the user's own selected storage; and
- uninstall MailBridge to remove its local application, configuration and runtime state.
Disabling or uninstalling MailBridge does not delete, move or otherwise change messages in Outlook. Uninstalling also leaves Dropbox or other user-selected storage content untouched so that it is not silently destroyed. The user may delete MailBridge's files from that storage separately when appropriate.
