This privacy policy sets out what information we track and how we use it. By using this site, you consent to the collection of information in accordance with the terms of this privacy policy.

Collection & Use of Information

We do not collect any personally identifying information about users unless it has been knowingly and specifically supplied to us by the user. Personal data (name & email id.) which has been provided by website/app visitors for product purchase and registration is controlled by Mailcastr for the purposes indicated.

We will not disclose any personal information about users to any outside party unless the user has been advised of this possibility before providing the personal information.

We collect general information on what pages users visit and information volunteered by users. The information we collect is used to determine how we can best communicate with you to inform you of service updates, new projects and other important and relevant information.

Information collected from individual site visitors is never shared, rented or sold. We reserve the right to access and disclose individually identifiable information in order to comply with applicable laws and lawful governmental requests, to operate our systems properly or to protect our rights and property.

Gmail Permissions

Web Dashboard / Chrome Extension - We ask for Gmail read-only permission to access data associated with email messages. This permission is used for providing email tracking functionality and we only store email data such as from, to and subject. We do not store email body.

Android Application - Mailcastr android application allows the user to access tracking data and it also functions as a basic email client. This email client functionality requires full access to the user's Gmail inbox. This access permission is only being used on the client side (User's own device). We send email metadata (from, to and subject) to our server only when the user uses email tracking functionality.

Gmail Add-on - Maiclastr add-on for Gmail requires access to currently opened email data. Add-on will check if the email contains tracking data embedded by Mailcastr and will display tracking data associated with that email. Connect to an external service permission is used to connect to Mailcastr server to retrieve this tracking data. Add-on will also request permission to access user's timezone information. This is to display tracking data, ie. time when the recipient opens the email, in user's own timezone.
