Privacy Policy

This privacy policy governs your use of the software application MailDroid/MailDroid Pro ("Application", "MailDroid", "App") for mobile devices that was created by Flipdog Solutions, LLC ("Flipdog Solutions" "we", "us", "our") registered in New York, USA. MailDroid is a mobile email client that connects directly to your mail server(s) in order to obtain mail as well as the ability to compose and send mail. We respect your privacy and are committed to protecting your personal info.

Ads Version

MailDroid has two different versions that we support. The ad version and the pro version which is ad free. The pro version is a different build that does not contain the SDKs of the ad companies so it can not serve ads. We work with third party advertising networks, who need to know how you interact with advertising provided in the Application which helps us keep the cost of MailDroid free. The ad version does show ads that are both banner and inline native ads. Age and gender, if supplied to MailDroid will be sent to the ad company. Your Google Advertising-ID is also sent to the ad company as required by Google. No data from your email or anything that you may compose and send is ever sent to any ad company.

Opt-out Ads

You can not opt-out of ads within the ad version of MailDroid. You can stop showing ads in the Application easily by uninstalling the Application. You may use the standard uninstall processes as may be available as part of your mobile device or via the mobile application marketplace or network. Finally, you can install the MailDroid pro version which has no ads.

Pro Version

The pro version of MailDroid makes periodic calls to the Google Play licensing server to validate the license. If the license is considered invalid, the application will fail to work.


MailDroid is a pure email client which means we connect directly to your mail server (IMAP, POP, Exchange). We have no in-between server that collects or looks at email. We do have a server where you can send anonymous bug reports which includes the error as well as your Android version, Locale, and device version. This data is sent on demand and you can always cancel and not send it.

Information Collected

If you email the FlipdogSolutions or MailDroidDev accounts with issues/concerns/feature requests, we will keep your email address in our address book on Google so we can respond to you and update you on bugs and features. On some occasions, we may send out a newsletter on new features and updates and that will always have an unsubscribe option available. We will not share your email with other companies.

Google/Gmail Data

MailDroid allows you to access your Gmail accounts over oAuth2 authentication. All account data including the content of the email, token, server information, labels, contacts and any other portion related to data is stored locally on the Android device. There is no data from your account(s) stored on any server or sent back to any other system.Flipdog Solutions complies with all requirements set forth to protect your data. Any emails sent from the system also do not go through any servers except through Gmail. If you are subscribed to the spam solution, MailDroid will locally on your device look for spam keywords or blacklisted IPs from your mail headers. All data itself is once again only stored locally.


MailDroid (as of version 4.35) does not collect information about the location of your mobile device.

Third Party Access

If Flipdog Solutions, LLC is involved in a merger, acquisition, or sale of all or a portion of its assets, you will be notified via the description in the store and/or a prominent notice on our Web site of any change in ownership or uses of this information, as well as any choices you may have regarding this information.

Tracking and Analytics

MailDroid uses Flurry (owned by Yahoo) for advertising in the ad version. We do not use their service for tracking anonymous stats and analytics within the app other than the MailDroid version being used and Android OS version.


MailDroid has the ability to add to your calendar if you choose to do so by importing in an event attached to an email. MailDroid does not read or access your calendar in any other way.


MailDroid has access to your local address book in order to make sure that when you type an email address, it will auto-fill and offer suggestions. We do not read anything else from that address book or send out anything to your contacts.

Security and Authentication

When you create accounts in MailDroid, you are allowing MailDroid to have permission to securely access your email in those accounts. Where possible, MailDroid uses OAuth2, which is a standard authorization protocol that allows third parties to access user data without the need to know a user\'s password. This means that MailDroid will never see or transmit your password and instead, will use a token to log into that account. This token is cryptography signed and can't be used to get an account password. MailDroid supports oAuth2 for Gmail, Hotmail/Outlook, Yahoo and AOL accounts. Please be sure that you are on the latest version (currently 4.35 as of July 2016) to make sure you are able to set your account up using this protocol. MailDroid will use SSL or STARTTLS (SSLv3, TLSv1, TLSv1.1. TLSv1.2) when speaking with your mail server assuming that you have clicked the SSL checkbox. What mechansim is used will depend on what your server supports. In some cases, MailDroid will need to use the SSL protocol over STARTTLS since the mail server may have compatability issues. Also, depending on your version of Android, it may be forced to use a lower protocol.

Links to other Services or Sites

Any links to websites or services that appear within emails from third-parties received by MailDroid are not the responsibility of MailDroid. By using the app, you agree that MailDroid does not have any control over third-party sites or services, are not MailDroid\'s responsibility, and this privacy policy does not apply to them.

Your Consent

By using the Application, you are consenting to this Privacy Policy now and as amended by us.

Changes to Policy

As MailDroid continues to grow and evolve, we may update this Privacy Policy in order to keep up with changes in our business and practices. By continuing to use MailDroid, you agree to be bound by the terms of the new Policy.
