1.2. In order to use the Service, you must first agree to the Terms. You can agree to the Terms by actually using the Service. You understand and agree that Google will treat your use of the Service as acceptance of the Terms from that point onwards.

1.3. You may not use the Service if you are a person barred from receiving the Service under the laws of the United States or other countries including the country in which you are resident or from which you use the Service. You affirm that you are over the age of 13, as the Service is not intended for children under 13.

2. Your Account and Use of the Service

2.1. You must provide accurate and complete registration information any time you register to use the Service. You are responsible for the security of your passwords and for any use of your account.

2.2. Your use of the Service must comply with all applicable laws, regulations and ordinances, including any laws regarding the export of data or software.

2.3. You agree not to (a) access (or attempt to access) the administrative interface of the Service by any means other than through the interface that is provided by Google, unless you have been specifically allowed to do so in a separate agreement with Google, or (b) engage in any activity that interferes with or disrupts the Service (or the servers and networks which are connected to the Service).

3. Service Policies and Privacy

3.1. You agree to comply with the Google App Engine Program Policies included available at http://code.google.com/appengine/program_policies.html (or such URL as Google may provide) (the "Program Policies") which is incorporated herein by this reference and which may be updated from time to time.

The Service shall be subject to the privacy policy for the Service available at http://code.google.com/appengine/privacy.html (or such URL as Google may provide), which references and incorporates Google's privacy policy available at http://www.google.com/privacy.html. You agree to the use of your data in accordance with Google's privacy policies.

3.3. You agree that you will protect the privacy and legal rights of the users of your application. You must provide legally adequate privacy notice and protection for those users. To do so, at a minimum, you must incorporate the privacy terms available at http://code.google.com/appengine/privacy.html into the privacy policy for your application. If the users provide you with user names, passwords, or other login information or personal information, you must make the users aware that the information will be available to your application and to Google.

3.4. If the user provides you with Google Account information, you may only use that information to access the user's Google Account when, and for the limited purposes for which, the user has given you permission to do so.

4. Fees for Use of the Service

4.1. Subject to the Terms, the Service is provided to you without charge up to certain quotas. These quotas will be known as the "Fee Threshold" and can be found here.

4.2. A bill will be issued to your online account for all charges accrued in excess of the Fee Threshold.  For use of the Service in excess of any portion of the Fee Threshold, you shall be responsible for all charges up to the amount set in your online account, and shall pay all charges in U.S. Dollars or in such other currency as agreed to in writing by the parties.  Unless agreed to by the parties in writing, you shall pay all charges in accordance with the payment terms in the Service FAQ.  Late payments may bear interest at the rate of 1.5% per month (or the highest rate permitted by law, if less). Charges are exclusive of taxes. You are responsible for paying all taxes and government charges, and all reasonable expenses and attorneys fees Google incurs collecting late amounts. To the fullest extent permitted by law, you waive all claims relating to charges unless claimed within 60 days after the charge (this does not affect your credit card issuer rights). Charges are solely based on Google's measurements of your use of the Service, unless otherwise agreed to in writing. To the fullest extent permitted by law, refunds (if any) are at the discretion of Google and only in the form of credit for the Service. Nothing in these Terms obligates Google to extend credit to any party.  You acknowledge and agree that any credit card and related billing and payment information that you provide to Google may be shared by Google with companies who work on Google's behalf, such as payment processors and/or credit agencies, solely for the purposes of checking credit, effecting payment to Google and servicing your account. Google may also provide information in response to valid legal process, such as subpoenas, search warrants and court orders, or to establish or exercise its legal rights or defend against legal claims. Google shall not be liable for any use or disclosure of such information by such third parties. Google reserves the right to discontinue the provision of the Service to you for any late payments.

4.3. Google may change its fees and payment policies for the Service with ninety (90) days prior notice. However, Google may change the Fee Threshold limits at its discretion. Changes to the fees or payment policies will be posted in the Service FAQ or at http://code.google.com/appengine/terms.html (or such other URL Google may provide from time to time). Any outstanding balance becomes immediately due and payable upon termination of the Terms for any reason.

4.4. You may not develop multiple Applications to simulate or act as a single Application or otherwise access the Service in a manner intended to avoid incurring fees.
