Privacy Policy

Last updated May 17, 2019

Cheshmak. (“Cheshmak” “we,” “us,” and “our”), provides this privacy policy because we believe that consumers should have clear and comprehensive ways to understand how information about them is collected and used – both to provide our services and for third party advertising purposes. We’ve tried to write this policy in a way that is easy for consumers to understand at a “high level,” while still providing detail to allow sophisticated users (and privacy advocates) to understand what data models we’re engaged in, and more generally, how interest-based advertising works.

We’ve also provided a section about the choices that you have with respect to “interest based advertising,”, and we encourage you to read that section and exercise your “opt out” rights if you’re inclined to do that. (But because interest based advertising leads to more relevant (and thus, less annoying) advertising, we hope you won’t do that.)

Introduction and Background

Cheshmak’s provides SDKs to mobile app developers and data and analytics services to other data partners and advertisers. These mobile SDKs permit app developers to send, manage, optimize and customize push notifications to their users. All of these services (further described in this privacy policy) are referred to collectively as our “Services ,” and all of these developers, partners and advertisers are referred to collectively as our “Clients .”

This privacy policy (the “Privacy Policy ”) explains how we may collect, use, store, and disclose information about the end users (“End Users ”) of third-party mobile applications that use our Services. We separately describe how we collect, use and share that website information (“Cheshmak Website Information ”) in Section 4, below.

We encourage consumers to learn about how information (including information we collect) can be used to market to them, and how to exercise their choices to permit or, if they prefer, to limit such marketing. We describe some ways consumers can exercise that choice or opt out of marketing in Section 6, below, titled Consumer Control & Opt Out Options .

1. Our SDKs: Information We Collect and Services We Provide

We refer to the information we collect from our SDKs as the ‘SDK Information .” The SDK Information includes (or may include) the following:

Information Collected About End Users by Our Mobile SDKs

As noted above, we refer to all of the above collectively as the “SDK Information .”

2. How We Use the SDK Information

We use the SDK Information to provide a variety of Services to our Clients. This includes:

We, or ad and data platforms we work with, may deploy online cookies to track to associate users (and these cookies) with Mobile IDs. We or they may do this to resolve user identifies across platforms, and to better or more accurately target relevant ads to users (such as to a brand’s customers). You can learn more about cookies and similar technologies, such as web beacons and SDKs, in the Section titled “Cookies and SDKs .” We may also “append” or combine certain SDK Information (such as hashed email addresses) to other information provided by third party data providers, to learn more about End Users or to provide advertising and analytics services.

3. How and Why We Share the SDK Information.

To Provide Services to Apps Using the SDKs

To Provide Services to Marketers, Advertisers and Platforms They Work With

We also share SDK Information to provide or help us to provide advertising and marketing services as we have described in Section 3, including as follows:

The processes we’ve described above often involves cookies or similar technologies, which may be associated with other information about you, e.g., your interests, demographics or transactions. This is known generally as “Interest-Based Advertising.” We encourage users who are interested in controlling or learning about this type of “interest-based advertising” to go to Section 6, titled “Consumer Control & Opt-Out Options , or go to this this page operated by the online ad industry trade association.

We may also share the SDK Information with third parties:

Even when you no longer access the SDKs, we may continue to use and share your Information as described in this Privacy Policy.

How We Share the Cheshmak Website Information

5. Cookies and SDKs 

As described in Section 4 our Clients or Partners may use the above technologies (sometimes, in combination with each other or other data such as IP addresses or hashed or de-identified data files) to coordinate identifiers across platforms, browsers or devices, to more efficiently analyze or target advertising.

6. Consumer Control & Opt-Out Options.

In most cases, consumers have control over whether or not they would like to receive relevant advertisements and marketing email from our Clients.

You may in most cases opt out of receiving push notifications by going to your device “Settings” and clicking on “Notifications,” and then changing those settings for some or all of the apps on your device. (Different device configurations, or updates to devices, may affect or change how these settings work.)

Your choice to opt out of “Notifications” from the Cheshmak platform will not affect ads placed by any other organization.

 You can opt out of many of the platforms and service providers that facilitate online interest-based advertising by visiting the Digital Advertising Alliance’s consumer education and opt-out page, at This type of opt out is cookie based, which means that if you replace or upgrade your browser, or delete your cookies, you will need to opt out again. Opting out in this way will not prevent you from receiving ads – it will just make the ads you see less customized to you.

You can opt out of having your mobile advertising identifiers used for certain types of interest-based (also called “cross-app”) mobile behavioral advertising, by accessing the “settings” on your Apple or Android mobile device, as follows:

Please note that these platforms control how these settings work, so the above may change. Likewise, if your device uses other platforms not described above, you should check the settings for those devices.

Advertisers may also provide ways for you to opt out from or limit their collection of information from and about you. Please refer to the privacy policies for retailers and applications to learn more about their privacy practices.

You may opt not to receive promotional emails from us by contacting us as indicated below or by following the “unsubscribe” instructions in any promotional email you receive from us. Please note, however, that we may still send you non-promotional emails about your relationship with us.

7. Data Access and Retention

Generally speaking, we retain the SDK Information for as long as necessary to achieve our objectives as detailed in this Privacy Policy, and to comply with our legal obligations, resolve disputes and enforce our agreements.

8. Data Security

We have administrative, technical, and physical safeguards in place in our physical facilities and in our computer systems, databases, and communications networks that are designed to protect information contained within our systems from loss, misuse, or alteration. No method of electronic transmission or storage is 100% secure. Therefore, we cannot guarantee absolute security of your Personal Information and Non-Personal Information.

We are not responsible for the privacy practices or disclosures of  applications that use our Services. Likewise, when you access the Cheshmak Website, you may be directed to other websites that are also beyond our control. We encourage you to read the applicable privacy policies and terms and conditions of such third parties, and the industry tools that we have referenced in this Privacy Policy. This Privacy Policy, however, only applies to the Cheshmak Site and the Services.
