Terms of Use

Last updated: 3 November 2026

Postlane is published by Black Rabbit. These terms describe the intended use and limitations of the current free developer preview. Questions can be sent to [email protected].

What Postlane does

Postlane is a Windows application for copying email between supported mailboxes. You select the source and destination accounts, choose the folders and review their destination mappings. It does not change your DNS records, domain ownership or mail delivery settings.

Permission to use your mailboxes

Use Postlane only with mailboxes and data you own or are authorized to access and transfer. You are responsible for obtaining any permissions required by your organization, account holders or applicable law. Do not use the application to gain unauthorized access, misuse personal information or interfere with another person's mail service.

The current free edition

The current developer preview is available without a usage fee. Black Rabbit permits you to install and use the preview for authorized mailbox migrations, including your own business mailboxes. Third-party components remain subject to their respective licenses. Any future paid edition will have separately presented terms; using this preview does not enroll you in a paid subscription.

Review before and after copying

Check the selected accounts and folder mappings before starting. Keep an appropriate backup of important email, and verify the destination messages and attachments after the transfer. Original messages remain in the source mailbox, but that is not a substitute for an independent backup.

Saved progress can skip confirmed copies recorded by Postlane. It is not universal duplicate detection for messages copied by other tools or older versions. If a previously copied message is missing at the destination, the application can offer a choice to restore it or keep destination changes. Uncertain server responses may require review before another copy is attempted.

Providers and availability

Connection and copying depend on your internet connection, server capacity, account permissions, provider policies and service availability. Google or Microsoft sign-in may require an eligible account, configured test access or administrator approval. Provider limits and authorization changes can prevent or interrupt a transfer.

Preview limitations

This is development software. Features may change, and uninterrupted or error-free operation is not guaranteed. The website's animated diagrams and terminal examples use simulated data; they are not a transfer-speed benchmark or a guarantee of results for your mailbox. Review the requirements and release notes for the version you install.

Nothing in these terms excludes or limits rights or liability that cannot lawfully be excluded or limited. These terms do not promise a support response time, a service-level agreement or future feature availability.

Privacy and support

Read the Privacy Policy for information about local processing, saved credentials and diagnostics. Contact [email protected] for support. Do not include passwords, tokens or unnecessary mailbox content in a support request.

Updates to these terms

Black Rabbit may publish revised terms for future versions. Material changes will be identified with the applicable release or notice. The date above identifies this version of the terms.

POSTLANE / BLACK RABBIT

Privacy Policy

Last updated: 3 November 2026

This notice explains how Postlane handles information in its current desktop edition and how to contact its publisher, Black Rabbit, at [email protected].

Your email takes a direct route

Postlane copies messages between the mailboxes you choose. Email data passes through your Windows computer directly between your mail providers. It is not sent through a Black Rabbit migration server. Original messages remain in the source mailbox.

Information used by the application

The application uses the connection details you provide, your selected folders, message data and transfer metadata to perform the migration. For Google and Microsoft accounts, sign-in takes place in your browser with the provider. Postlane receives authorization tokens to access the selected mail service rather than asking for your provider password.

Google's IMAP interface requires the broad https://mail.google.com/ permission. This permission is broader than Postlane's actions: Postlane reads selected source messages, adds copies to the destination and creates folders when requested. It does not send messages through SMTP or delete source messages. A destination write check may create and remove a new empty test folder.

Local storage and saved connections

Messages use temporary local files during copying. Progress records, folder identifiers, message identifiers, transfer history and diagnostic reports are stored locally for recovery and review. They are not a backup of your mailbox contents. Local records remain on your computer until removed; Black Rabbit does not operate a remote store for these migration records.

If you choose to remember connections, saved credentials and OAuth cache data are encrypted for your Windows user account using Windows data protection. Forget saved connections removes locally remembered credentials and tokens. It does not erase transfer history or revoke permissions at Google or Microsoft. You can revoke access through your provider's account settings. Contact us if you need help locating or removing local application data.

Diagnostics and support

The current desktop edition does not implement advertising or telemetry and does not automatically upload diagnostic reports. A diagnostic export is saved locally when you request it. If you contact Black Rabbit, we receive your contact details and the information you choose to send so that we can respond and investigate the issue. Review reports before sharing them and never send passwords, authorization tokens or unnecessary email content.

Support correspondence is handled for the purpose of responding to your request, based on our legitimate interest in providing support or, where applicable, taking steps at your request in connection with a service. We retain correspondence only for as long as needed to resolve the request and meet applicable legal or dispute-handling obligations. Ask us for information about a particular support record or to request its deletion.

This website and external services

The Postlane theme serves its fonts and artwork locally and does not itself add analytics, advertising trackers or a newsletter service. A website visit still involves technical information such as your IP address and requested URL being processed by the hosting and security infrastructure. WordPress features, Cloudflare settings and separately installed plugins can affect cookies, logs, recipients and retention. This desktop-app notice does not imply that all website infrastructure is free of cookies or logs. Contact [email protected] for details about the site's current configuration.

Your chosen mail providers process the mailbox data under their own privacy notices and account settings. Their services may process data in different countries. Links to external sites take you to services governed by their own notices.

Your choices and rights

You choose the mailboxes and folders, can stop a transfer, can decline to remember connections, and control whether to export or share diagnostics. Where applicable, you may request access, correction, deletion, restriction or portability of personal information held by Black Rabbit, or object to processing. If processing relies on consent, you may withdraw it without affecting the lawfulness of earlier processing. The availability of each right depends on the circumstances and applicable law.

Send privacy requests to [email protected]. You may also lodge a complaint with the competent data protection authority, including the Hellenic Data Protection Authority. Black Rabbit cannot access or erase messages held only in your own mail accounts; those requests should be addressed to the relevant provider or account administrator.

Changes and contact

Changes to Postlane's data handling will be reflected in an updated notice. For questions about the application or this notice, contact Black Rabbit at [email protected].
