and we always go all out to ensure its security. To live up to your trust, we
adhere to principles such as consistency between rights and responsibilities,
clear purposes, selective consent, minimum sufficiency, security assurance,
subject participation, and openness and transparency to protect your personal
information. We solemnly promise to implement various security protection
measures in accordance with mature industry security standards. Before using

(I)
Information Required to Achieve Core Functions
Device
Connection
Device
identification information: Collects unique
identifiers of the mobile device (such as MAC address, device serial number)
and device name for device matching during connection.
Network
information: Obtains Wi‑Fi information (SSID, BSSID) connected to the mobile
device to establish a secure data interaction channel.
1. Location Information: In some
Android device systems, when you use the Wi-Fi P2P function for device
connection, enabling the location permission is a necessary step. We obtain the
location permission not to locate your geographical location, but to meet the
operating logic of the Wi-Fi P2P service in the device's underlying system.
After this permission is enabled, it only helps the device more effectively
search for and identify devices (such as Box devices) that can be P2P -
connected within the same local area network, so as to achieve fast and stable
device connection and data interaction and ensure the normal operation of the
"Add Device" and related screen mirroring functions. We will not
store, analyze, or use your location information in scenarios unrelated to the
screen mirroring function, nor will we share the location information with
third parties for advertising and other purposes.
2. Recording Information:
When you use functions involving recording (such as casting local audio files,
or when certain video applications contain audio that needs to be collected by
the mobile phone microphone and then cast for playback, if there are such
functions), we will collect your audio information after you authorize the
opening of the recording permission. These audio files are only used for
transmission and playback between devices to achieve the audio - casting effect
you need, and will not be stored or used for other purposes without your
knowledge.
1. Log Information: To optimize our
services, we will record operation logs while you are using the app, including
information such as function usage time and operation steps. This information
is used for troubleshooting and performance optimization, and the logs do not
contain personally identifiable information.
2. Crash Information: When the
App crashes, we will collect system logs and stack trace information at the
time of the crash to quickly locate and fix problems and improve the stability
of the App.
We
use the collected device information and usage information to monitor and
optimize the performance of the App, ensuring that it can operate stably under
different devices and network environments. For example, by analyzing the
relationship between device models, operating system versions, and the
stability of the App's operation, we can conduct targeted code optimization and
compatibility adjustments to reduce problems such as crashes and lags.
Based
on your usage behavior data, we can understand which functions are popular
among users and which functions need improvement. For example, if we find that
the usage rate of a certain function is low, we may redesign or adjust it to
make it more in line with user needs and usage habits; for functions frequently
used by users, we may further optimize their performance to improve the
convenience of operation and response speed.
A
cookie is a small data file with a commonly used anonymous unique identifier.
These files are sent from the websites you visit to your browser and stored in
the internal memory of your device.
Our
service does not explicitly use these "cookies". However, the
application may use third - party code and libraries that use
"cookies" to collect information and improve its services. You can
choose to accept or reject these cookies and know when cookies are sent to your
device. If you choose to reject our cookies, you may not be able to use some
parts of this service.
We
will not sell, rent, or share your personal information with any third party
for marketing or other commercial purposes without your explicit consent. We
are committed to protecting your privacy and ensuring that your information is
only used within the scope specified in this privacy policy.
1. Necessary Sharing: Only when
devices are connected, we will share the device identification and network
information required for screen mirroring with the device.
2. Legal Requirements: In cases
required by law, such as in response to legitimate requests from courts,
government agencies, or other authorized authorities, we may legally share your
personal information. However, in such cases, we will, to the extent permitted
by law, try our best to ensure that the shared information is legally and
properly protected.
(III)How We Share Your
Information
(I)Principle of Non-Sharing
We will not sell, rent or share your personal
information with any third party for marketing or other commercial purposes
without your explicit consent. We are committed to protecting your privacy and
ensuring that your information is only used within the scope specified in this
Privacy Policy.
(II) Possible Sharing Scenarios
Necessary Sharing: Only during device connection, we
share the device identification and network information required for screen
mirroring with the connected device.
Legal Requirements: Where required by law, such as
responding to legitimate requests from courts, government agencies or other
competent authorities, we may lawfully share your personal information.
However, in such cases, we will make every effort within the scope permitted by
law to ensure that the shared information is legally and properly protected.
(III) Sharing for Providing
Advertising Services
Our App integrates third-party SDKs to
display advertisements to you (including non-personalized ads and personalized
ads), monitor ad performance and prevent fraud. These SDKs may collect and use
your device information when you use the App. Details are as follows:
Third-party SDKs and their affiliates may
adjust the types of data they process due to version upgrades, policy revisions
and other factors. Please refer to their publicly released official statements
for accurate information.

Consent for Users in the European Union
We
have integrated Google UMP (User Messaging Platform). Users located in the
European Union / European Economic Area will be presented with compliant
privacy options, and you may independently choose whether to accept
personalized advertisements.
1. Data Encryption: We use
encryption technology for the transmitted screen mirroring data and device
information. Audio information and search - assisting information related to
location permissions are also encrypted during transmission and storage to
prevent data from being stolen or tampered with.
2. Access Control: We limit the
information access rights of internal personnel and conduct regular security
audits. In particular, for access to information related to sensitive
permissions, we set more stringent approval and monitoring processes.
3. Emergency Response: We have
developed a data security incident emergency response plan to handle issues
such as information leakage in a timely manner. Once a security incident
involving sensitive data such as recording information and location -
permission - related information occurs, we will immediately activate the plan,
take measures to prevent the incident from expanding, and report to the
relevant departments and notify affected users as required.
We
attach great importance to the protection of minors' personal information. This
App does not provide services targeted at minors, and we do not deliberately
collect the personal information of minors. If we discover that we have
inadvertently collected the personal information of minors, we will immediately
take measures to delete the relevant information.
We
may update this policy due to business adjustments or changes in laws and
regulations. The updated policy will be prominently displayed in the App and
you will be reminded through application pop - ups and other means. If you
continue to use the App after the policy change, it means that you accept the
new policy. For major changes, we will also notify you via text messages,
emails, etc.
If
you have any questions, comments, or suggestions regarding this privacy policy,
or if you need to exercise your relevant rights, you can contact us in the
following way:

We
will process your feedback as soon as possible and reply within a reasonable
time (usually no more than 30 working days).
