ZMail - Privacy Policy

Last updated: October 4, 2026

Overview

ZMail (formerly ZHost Mail; "we", "our", "the service") is a webmail service operated by RampsBD. It is available on the web (for example at webmail.zhost.stream) and through the ZMail Android app (stream.zhost.webmail), which opens the webmail server you choose. This policy explains what data the app and our webmail servers collect, why, and what you can do about it.

Information We Collect

To provide your mailbox, the following data is sent from your device to the webmail server you sign in to and is stored on it:

• Email address and password: used to sign you in to your mailbox and to check it for new mail. The password is stored encrypted on the server.
• Email messages: the messages in your mailbox (sender, recipients, subject, body and dates) are synced from your mail server and kept in an encrypted cache so that your folders and search load quickly.
• Attachments and files: attachments you receive or upload when composing a message.
• Contacts: addresses you save to your address book.
• Profile details: the display name, profile picture, signature and preferences (labels, folders, settings) you choose.

On your device, the Android app stores your server address, email address and password so that it can sign you in automatically and check for new mail in the background.

We do not collect location, device identifiers, advertising IDs, contacts from your phone, or analytics or tracking data. The app contains no advertising, analytics or crash-reporting SDKs.

How We Use Your Information

Your data is used only to provide the service:

• Showing, searching and organising your email
• Sending email on your behalf through your mail server
• Checking for new email in the background and showing notifications
• Account management, such as linking several mailboxes to one sign-in

We do not sell your data and do not use it for advertising.

Optional AI Features

If your administrator enables the AI writing assistant and you choose to use it, the instruction you type and the related email text are sent to an AI provider (such as Xiaomi MiMo, Google Gemini or OpenAI) to generate the response. This happens only when you use the feature. The provider processes the text on our behalf to return the result.

Data Sharing

We do not share, sell or transfer your personal information to third parties, except:

• Your mail server, which delivers and stores your email
• The AI provider, only when you use the optional AI features described above
• When required by law

Data Security

• The app and webmail communicate with our servers over HTTPS (encrypted in transit)
• Passwords and the cached email are stored encrypted on the server
• Access to the servers is limited to the administrators who operate the service

Data Retention and Deleting Your Data

Your cached email, contacts and settings are kept while your mailbox is in use.

To request deletion of your ZMail account and data (RampsBD):

1. Send an email to [email protected] from the mailbox address you want deleted, with the subject "ZMail data deletion request".
2. Say whether you want only the data ZMail stores deleted, or the whole mailbox closed as well.
3. We confirm the request by replying to that address and complete it within 30 days.

What is deleted: your stored password, the cached copies of your email and attachments, your contacts, labels, profile details, signature, settings, linked-mailbox entries and AI usage records. If you ask for the mailbox to be closed, the mailbox and the email on the mail server are deleted too.

What may be kept: server logs (such as sign-in times and IP addresses) for up to 90 days for security, and anything we are required by law to keep.

To remove data from your phone only, sign out in the app, clear the app's data, or uninstall it. If your mailbox is provided by an organisation, that organisation's administrator can also delete it.

Children's Privacy

ZMail is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date.
