Dianping takes your privacy very seriously. This privacy policy governs and details the main privacy principles we apply to the data we collect through our services. 

Dianing specializes in creating personalized advertisements. We work with online partners to build advertisements for users who visit their mobile applications and with publishers to display personalized advertisements. 

To serve our ads in mobile applications we collect identifiers, such as Google Advertising ID or Apple IDFA depending on the operating system of your mobile device. These identifiers consist in a string of technical and random characters singling out your device that Dianping stored by Dianping with a hash (non reversible encrypting method). 

To opt-out from advertising served by Dianping in mobile applications, you must be browsing in applications.    Android Users (version 2.3 and above)  To use the “opt-out of interest-based advertising” option, follow the  instructions provided by Google here: Google Play Help. If you don’t have the Google Play Services installed on your device, you won’t receive Dianping services. 

Please note that this is a device setting and will disable interest-based ads from all providers, and not just for Dianping 

iOS users (version 6 and above)  To use the “Limit Ad-Tracking” option, follow the instructions provided by Apple here: Apple Support Center  Please note that this is a device setting and will disable interest-based ads from all providers, and not just for Dianping 

In order to serve you advertisements that are the more relevant to your interests, we collect data related to your browsing activity through equivalent identifiers that record: 

• - information related to your device (device type, operating system, version) 
• - and events related to the Dianping ad serving activity such as the number of ads displayed to you.  We also collect technical user identifiers from our advertising partners for the purpose of linking the different browsers and mobile apps you use and serve you relevant ads based on your behaviour across environments (“ID syncing”). For that purpose we process and store 
• - Mobile advertising IDs (such as Apple IDFA or Google AAID) which are specific technical data created by mobile manufacturers to allow personalization and customer analytics in a secure and non-identifying way for users.  

We do not collect any identifying information 

• - We do not know who you are. We do not know your address, your place of work, your date of birth, your email address, your phone number. We do not use or store your IP address for targeting purposes*. 
• - We do not collect hardware-based identifiers such as UDID, Mac Address.
• - We do not collect sensitive information (such as religion, political opinion, health…).

The security of your information is fundamental to Dianping. We have implemented industry-standard security measures, which include the use of firewalls and encryption. 

We retain the technical data that we collect for up to 13 months from the date of collection. Our cookies expire 13 months after they are last updated.
