Last modified: July 10, 2017

Welcome to Cheetah Mobile Inc.’s official website where you can find policies and terms governing your use of products and services provided by Cheetah Mobile Inc., its subsidiaries and affiliates (collectively as “Company,” “we,” “us” and “our”).

These Terms of Service (“ToS”) constitute a legal agreement between the user of our products and services (“user” or “you”) and the Company. It applies when a user accesses, uses or visits our website located at http://www.cmcm.com/ (the “Site”), the associated mobile application available for download in the Google Play Store and other third party app stores, or pre-installed on third party devices (the “App”), and/or the services provided through the Site and the App. In these ToS, the term “Service” means and includes the Site, the App and these services, individually or collectively.

We prepared these ToS to help explain the terms that apply to your use of the Service.

  1. Consent

By visiting the Site, downloading the App, or otherwise using the Service, you indicate your agreement to be bound by these ToS. If you do not agree with these ToS, you must not use the Service, and uninstall the App if you have already downloaded it.

  1. Privacy Policy

Our Privacy Policy, located at http://www.cmcm.com/protocol/site/privacy.html , is part of and is governed by these ToS. By agreeing to these ToS, you agree to be bound by the terms of the Privacy Policy and agree that we may use information collected from you in accordance with its terms.

  1. Notice Regarding Dispute Resolution

These ToS contain provisions that govern how claims you and we may have against each other are resolved, including an agreement and obligation to arbitrate disputes, which, subject to limited exceptions, will require you to submit claims you have against us to binding arbitration, unless you opt-out of arbitration as described below. If you do not opt-out of arbitration, you will only be permitted to pursue claims and seek relief (including monetary, injunctive, and declaratory relief) against us on an individual basis, not as part of any class or representative action or proceeding.

  1. Updates to these ToS

We may modify these ToS from time to time. We will notify you of material changes in accordance with applicable laws. If you do not agree with the proposed changes, you should discontinue your use of the Service and uninstall the App. If you continue using the Service after the new terms take effect, you will be bound by the modified ToS.

  1. Affirmative Representations

When you use the Service, you represent that:

  • your use of the Service does not violate any applicable law or regulation;

  • you are 13 years of age or older; and

  • you are of sufficient legal age or otherwise have legal capacity to legally enter into these ToS.

  1. Prerequisites and Activation

In order to use the Service, you must first agree to be bound by the terms of these ToS and our Privacy Policy.


In order to be able to activate the App, you may need to agree to allow the App to have access to the following information and features located on the user’s device:

  • Device and Application History

  • Identity

  • Photos and media files

  • Camera; microphone

  • Wi-Fi Connections

  • Device ID and Call Information.


In addition, to enable certain features, the user must agree to enable access to additional information.

  1. Arbitration Agreement

Please Read This Following Clause Carefully

It May Significantly Affect Your Legal Rights, Including Your Right to File a Lawsuit in Court


  1. Initial Dispute Resolution

We are available by email at the address provided in the “How to Contact Us” Section to address any concerns a user may have regarding the Service. Most concerns may be quickly resolved in this manner. For any dispute you have with the Company, you agree to first contact us and attempt to resolve the dispute with us informally. We each agree to resolve any dispute arising out of or in connection with, or relating to this Agreement directly through consultation and good faith negotiations, which shall be a precondition to either party initiating a lawsuit or arbitration.


  1. Agreement to Binding Arbitration.

If we do not reach an agreed upon solution within a period of thirty (30) days from the time informal dispute resolution is pursued pursuant to section “Initial Dispute Resolution” above, then either party may initiate binding arbitration.


All claims arising out of or relating to these ToS (including its formation, performance and breach), the parties’ relationship with each other and/or your use of the Service shall be finally settled by binding arbitration administered on a confidential basis by the American Arbitration Association in accordance with the provisions of the Consumer Arbitration Rules of the American Arbitration Association (the “AAA”), excluding any rules or procedures governing or permitting class actions. The arbitrator, and not any federal, state or local court or agency, shall have exclusive authority to resolve all disputes arising out of or relating to the interpretation, applicability, enforceability or formation of these ToS, including, but not limited to, any claim that all or any part of these ToS is void or voidable. The arbitrator shall be empowered to grant whatever relief would be available in a court under law or in equity. The arbitrator’s award shall be binding on the parties and may be entered as a judgment in any court of competent jurisdiction. The interpretation and enforcement of these ToS shall be subject to the Federal Arbitration Act.


THE AAA’S RULES GOVERNING THE ARBITRATION MAY BE ACCESSED AT WWW.ADR.ORG OR BY CALLING THE AAA AT 1.800.778.7879. TO THE EXTENT THE FILING FEE FOR THE ARBITRATION EXCEEDS THE COST OF FILING A LAWSUIT, WE WILL PAY THE ADDITIONAL COST. IF WE ARE REQUIRED TO PAY THE ADDITIONAL COST OF THE FILING FEES, YOU SHOULD SUBMIT A REQUEST FOR PAYMENT OF FEES TO AAA ALONG WITH YOUR FORM FOR INITIATING THE ARBITRATION, AND WE WILL MAKE ARRANGEMENTS TO PAY ALL NECESSARY FEES DIRECTLY TO AAA. THE ARBITRATION RULES ALSO PERMIT YOU TO RECOVER ATTORNEY’S FEES IN CERTAIN CIRCUMSTANCES.


THE PARTIES UNDERSTAND THAT, ABSENT THIS MANDATORY PROVISION, THEY WOULD HAVE THE RIGHT TO SUE IN COURT AND HAVE A JURY TRIAL. THEY FURTHER UNDERSTAND THAT, IN SOME INSTANCES, THE COSTS OF ARBITRATION COULD EXCEED THE COSTS OF LITIGATION AND THE RIGHT TO DISCOVERY MAY BE MORE LIMITED IN ARBITRATION THAN IN COURT.


  1. Class Action and Class Arbitration Waiver.

You and the Company each further agree that any arbitration shall be conducted in your respective individual capacities only and not as a class action or other representative action, and you and the Company each expressly waive your respective right to file a class action or seek relief on a class basis. If any court or arbitrator determines that the class action waiver set forth in this paragraph is void or unenforceable for any reason or that an arbitration can proceed on a class basis, then the arbitration provision set forth above in Section “Agreement to Binding Arbitration Above” shall be deemed null and void in its entirety and the parties shall be deemed to have not agreed to arbitrate disputes.


  1. Exception - Small Claims Court Claims.

Notwithstanding the parties’ agreement to resolve all disputes through arbitration, either party may seek relief in a small claims court for disputes or claims within the scope of that court’s jurisdiction.


  1. 30 Day Right to Opt Out.

You have the right to opt-out and not be bound by the arbitration and class action waiver provisions set forth in this Section “Arbitration Agreement” by sending written notice of your decision to opt-out to the address provided in the “How to Contact Us” Section.


The notice must be sent by you within thirty (30) days of your downloading of the App, otherwise you will be bound to arbitrate disputes in accordance with the terms of those sections. If you opt-out of these arbitration provisions, we also will not be bound by them.


  1. Exclusive Venue for Litigation

To the extent that the arbitration provisions set forth in above do not apply, the parties agree that any litigation between them shall be filed exclusively in state or federal courts located in Santa Clara County, California (except for small claims court actions which may be brought in the county where you reside). The parties expressly consent to exclusive jurisdiction in California for any litigation other than small claims court actions.

  1. Entire Agreement

This ToS constitutes the entire agreement between you and the Company with respect to the subject matter hereof and supersedes all previous and contemporaneous written and oral representations, proposals, negotiations, and communications.

  1. Assignment

The Company may assign this TOS or any of the rights or obligations hereunder and any causes of action arising hereunder to any third party without necessity or obligation of notice to users.

  1. Waivers

The waiver or failure of either party to exercise in any respect any right or provision of these ToS will not be deemed a waiver of the applicable right or provision.

  1. Severability.

These ToS will operate to the fullest extent permissible by law. If any provision or part of a provision of these ToS is unlawful, void, or unenforceable, that provision or part of the provision is deemed severable from these ToS and shall not affect the validity and enforceability of any remaining provisions.

  1. Notice to California Users.
