- Privacy Policy

Privacy Policy from The live version of this document is available at This document is a part of Docracy's Terms of Service Tracker project, which tracks changes to terms of service and privacy policy documents of many of the world's top websites.

Mailbox is a mobile application and cloud service made with love in San Francisco, California by Dropbox, Inc. (“Dropbox”, “we”, “us”, “our”). Mailbox helps you manage your email, and in order to provide you with that service, we need to collect, store, and in rare cases, share your personal information. This Privacy Policy explains how we do that. Terms that are not defined in this Privacy Policy have the meaning given them in our Terms of Service.

Mailbox has been awarded the TRUSTe certification and complies with E.U. Safe Harbor. For more information on this, please continue to the Security section of this Privacy Policy.

Information Collection and Use

When using Mailbox, you agree to our collection, transfer, processing, storage, disclosure and other uses of your information as described here. If you have any questions or comments about our policy, you can contact us at [email protected]

What sort of information do we collect?

Information you provide us

We ask for certain personal information when you register for Mailbox (either in the app or on our website) or if you correspond with us, like your first and last name, e-mail address or phone number. If you input your phone number to receive information from us, you understand that standard SMS rates apply. If you email us, we may keep your message and contact information so we can respond to your request. We use this information to operate, maintain, and provide to you with Mailbox’s features and functionality.


Mailbox is designed to help you manage your email account with other providers, like Gmail. When you link your email accounts (provided by third parties) to Mailbox, you give Mailbox permission to securely access your information contained in or associated with those accounts. If you link your third party account to Mailbox, that third party may also pass certain information along about your use of its service. While Mailbox does not store your password to these email accounts, the service does securely store some emails on a temporary basis in order to deliver them to you as quickly as possible and keep track of your deferred messages.

Push Notifications

Mailbox sends push notifications to your mobile device when it has an update and when you have a new message. You may turn these off at the device level by following the instructions on your device, but please be aware that if you do, you will not receive any future alerts.

Email Contacts

Mailbox provides the ability to interface with your phone’s contact list (e-mail addresses and names) in order to add email recipients easily and securely. You will be prompted for permission within the app before Mailbox can access your contacts. We will not use this information for any purpose other than to provide the Mailbox service to you.

Local storage

Mailbox stores information locally on your device, like your most recent emails, snoozed emails, recently archived emails and emails you’ve put in lists.

Customer Testimonials

We obtain customer testimonials on our web site from public sources, which may contain personally identifiable information. To request removal of your personal information, contact us at [email protected]

Social Media

The Mailbox website includes links to third party social media sites like Twitter. These links may collect your IP address and may set a cookie to enable the social media feature to function properly. These features are hosted by a third party and your interactions are governed by the privacy policy of the company providing them. We have no control over the privacy practices of any third party social media sites.


We may use the information we collect or receive to communicate with you directly. For example, you may receive emails from us containing company updates, promotions, marketing, or special offers. We may also keep track of how you interact with links in these messages. We do this to be sure our communications and our products get better over time. If you’d rather not receive these emails, you may opt-out of receiving them by following the unsubscribe link located at the bottom of each communication or by emailing us at [email protected] We also use your information to send you Mailbox-related emails (e.g., account verification, changes/updates to features, technical and security notices) – these Mailbox-related communications are important, so you cannot opt out.

Geo-Location Information

Photos you take or attach in Mailbox may contain recorded location information. If you’d rather not have location data associated with your photos, please consult the documentation for your mobile device’s camera feature to disable it. Some of the information Mailbox uses to communicate with your device - like its IP address - can be used to approximate the device’s location. This information may be used to administer, analyze and improve Mailbox. If you'd rather not have Mailbox use your information for these purposes, please contact us at [email protected]

Analytics for Web and Mobile

We use web and mobile analytics software to measure traffic and usage trends and to help us better understand the functionality of Mailbox on your phone. The web tools collect information sent by your browser, including the pages you visit and other information that assists us in improving Mailbox. The mobile software within Mailbox may record information such as how often you use the application, the events that occur within Mailbox, aggregated usage, performance data, and where the Mailbox application was downloaded from. We use this information only to administer, improve, monitor and analyze the use of Mailbox.


A cookie is a small text file that is stored on a user’s computer for record-keeping purposes. We use cookies on the Mailbox website, but we don’t link the information in those cookies to any personal information you submit. They are used to make it easier for you to navigate the Mailbox site and so we can analyze the interests of our users to enhance the experience on our site. Cookies may be used by third parties: we do not have access or control over these cookies, and they are not covered by our Privacy Policy.

Device Identifiers

When you access Mailbox on a mobile device (like a smart-phones or tablet), we may access, collect, monitor or remotely store device identifiers (such as a “UDID” - a small data file associated with your mobile device which uniquely identifies it). This file stores data about your device’s hardware, operating system or other software and data sent by Mailbox, and conveys information about how Mailbox is used. This device identifier may persist on your device to help you log in faster and enhance your navigation through Mailbox. Some features of Mailbox may not function properly if this device identifier is impaired or disabled.

Changing or Deleting Your Information

If your information changes, or if you wish to discontinue use of Mailbox, you may update or delete it by visiting your account settings within the mobile application or by emailing us at the email address listed below. In some cases we may retain copies of your information if required by law. If you have questions on how to change or delete your information, please contact [email protected] We will respond to your access request within 30 days.

Data Retention

We will retain your information for as long as your account is active. If you wish to cancel your account or request that we no longer use your information to provide you services contact us at the email address listed above.  We will retain and use your information as necessary to comply with our legal obligations, resolve disputes, and enforce our agreements.

Sharing and Disclosure

We will never share, rent or sell your information to third parties outside Dropbox and its group companies (including subsidiaries and affiliates) without your consent, except as noted below:

  • Information you share with others: Mailbox lets you share information with others, for example, through emails. Remember that when you share information via email, the recipient or recipients are responsible for keeping it private and respecting whatever intellectual property you have in that information.
  • Service Providers: We engage third-party business partners to provide you with Mailbox and to perform functions and provide services to us, like Amazon for storage and Mixpanel for analytics. Those business partners will be given limited access to your information as is reasonably necessary to provide Mailbox.
  • Compliance with the Law: We may disclose your information if we believe it’s necessary in order to comply with the law, such as to comply with a subpoena, regulation or legal request, respond to a government request, to address fraud or security issues, to protect the safety of any person, or to protect our own rights or property.
  • Business Transfers: If Dropbox is involved in a bankruptcy, merger, acquisition, reorganization or sale of assets, your information may be transferred as part of that transaction. The assurances in this Privacy Policy will apply to your information if/when it’s transferred to a new entity. You will be notified via email and/or a prominent notice on our website of any change in ownership or uses of your personal information, as well as any choices you may have regarding your personal information.
  • Anonymized Information: Should we need to share data about our usage with third parties (such as investors or partners), we will aggregate it and strip it of all personally identifiable information.


Security is extremely important to us. We use industry leading security practices to preserve the integrity of all your Mailbox data. For example, when you transmit sensitive information and when you send and receive emails, Mailbox encrypts the transmission of that information using secure socket layer technology (SSL). However, no method of electronic transmission or storage is 100% secure, so we cannot guarantee absolute security. Dropbox is not responsible for the functionality or security measures of any third party. If you have questions about this feel free to contact us at [email protected]

Your information collected through Mailbox may be stored and processed in the United States or any other country in which we or our affiliates operate. In order to provide the service to you, we may transfer personal information to affiliated entities, or to other third parties across borders and from your country or jurisdiction to other countries or jurisdictions around the world. If you are located in the European Union or other regions with laws governing data collection and use that may differ from U.S. law, please note that we may transfer information, including personal information, to a country and jurisdiction that does not have the same data protection laws as your jurisdiction, and you consent to the transfer of information to the U.S. or any other country in which we or our parent, subsidiaries, affiliates or service providers maintain facilities and the use and disclosure of information about you as described in this Privacy Policy.

In the event that any information is compromised as a result of a breach of security under our control, we will take reasonable steps to investigate the situation and notify those individuals affected.
