Puffin Web Browser (free with sponsored ads) on Android Privacy Policy

Last Modified: February 19, 2019

This Privacy Policy explains what information CloudMosa collects about you, your usage, and what we may do with that information.

Information can be collected when you use Puffin Web Browser for Android (the “ App ”) and services (the “ Services ”). By using the App and Services you agree to the Privacy Policy. The Privacy Policy for the App and Services may change over time at our discretion without prior notice as we refine and add or remove features.

Information about You

The App provides ad-supported 24/7 Flash support and have no In-App-Purchase items. There is no user account on our cloud servers.

Furthermore, our system is state-less, i.e., once you quit the App and leave the Services, it is as clean as you were never there. In practice, there are ways to link your activities together by cross-referencing the logs. Nevertheless, there is no way to link back to your identity such as name, address or phone number.

Information about Your Usage

We log anonymous activities in the format of standard web logs, whose information includes source addresses, destination addresses and URLs. Once collected from the log servers, the logs are used to generate reports for internal data analysis. The logs are purged after 100 days. The reports have aggregated statistical data, which is insufficient to be cross-referenced to identify any individual user.

We may also collect information about the App version, App-specific IDs, and operating system versions, device models, location data of your mobile devices, as well as connection status during your usage of the App.

Since we serve ads in our free apps, we collect aggregate, anonymous statistics, such as the percentage of users who view a particular type of ads, to determine the third-party ad providers we work with.

You may choose not to provide anonymous usage data by upgrading to the Paid version of the App.

What We May Do with the Information

Logs are used for trouble-shooting and self-defense. Reports are used for debugging and business analytics. However, excessive amount of logs and reports are expensive to maintain. We purge the logs after 100 days and only keep the reports. Logs are only used internally, where recent reports are sometimes used externally, e.g., for fund-raising due diligence.

Information about your App version, operating system, device model, location data, and connection status may be shared with our third-party collaborators, including Agoop, a member of the SoftBank Group, for user research and service improvement purposes.

In principle, we do not comply with external requests for user information. The only exception is that we may cooperate with law enforcement agencies as required by law when we receive a request to aid in a criminal investigation.

No Log on Web Page Contents

Even though the URLs of the web pages are logged, the contents of the web pages are not logged. In fact, the contents will never be logged, and this policy will be strictly enforced. However, be aware of the possibility of surveillance by intelligence agencies in your home country and our home country.
