All functions and services provided by the product, including without limitation cloud phones and cloud numbers, are intended to assist Business Users with commercial activities such as market research, advertising, account operations, data analysis, and team collaboration.

You are solely and fully responsible for any websites, applications, content, products, and related activities that you operate, publish, or distribute through the Service.

1.4 You may select and order the required services online through the DuoPlus website. Before placing an order, carefully read the applicable Service Terms and independently decide whether to purchase based on your actual needs. The parties may also enter into a separate written agreement as required for their cooperation.

1.5 Certain services may require you and DuoPlus to enter into a separate service agreement, in electronic or paper form. You may decide whether to accept such an agreement and activate the applicable service based on your circumstances.

1.6 After submitting an order, you must complete payment promptly. If you fail to pay on time, or if a service is subject to time, inventory, promotion quantity, or other limits that prevent the order from being completed, you may be unable to use that service.

1.7 DuoPlus may from time to time offer promotions such as “limited-time free access,” “limited-time discounts,” or “recharge bonuses.” You understand and agree that such promotions may be time-limited, offered in stages, subject to quantity limits, or available only under specified conditions. You must purchase and use them in accordance with the applicable rules. Unless expressly stated otherwise in writing, different promotions cannot be combined.

1.8 Express exclusion: DuoPlus is not designed, provided, or sold for personal or everyday household consumption.

5. Fees

5.1 Prices and Payment

Please visit our payment policy page for the prices and latest promotions for all services. Some DuoPlus features are free, while others require payment. If you agree to our payment policy and order a paid feature, you undertake to pay the applicable fee. Prices for all services, including without limitation monthly software subscription fees, may change. Price changes will be published on the DuoPlus Pricing page or in the DuoPlus client.

We reserve the right to modify or discontinue the Service, or any part of it, at any time or from time to time. DuoPlus will not be liable to you or any third party for any modification, price change, suspension, or discontinuation of the Service.

5.2 Trial Subscriptions

We may offer each newly registered user a free DuoPlus trial subscription through the website so that the user can experience certain premium features without charge for a specified period. The applicable period will be stated when you select the offer.

By selecting a free DuoPlus trial subscription, you agree that, when the trial ends, it will automatically renew as the paid subscription version of the corresponding plan and the applicable fee will be automatically deducted from your payment account.

You agree that we may, without notice or liability, change or terminate any free-trial offer, limit access during a free-trial period, or restrict users from maintaining multiple free-trial subscriptions at the same time.

5.3 Paid Subscriptions and Automatic Renewal

Users may purchase paid subscriptions to premium DuoPlus features and agree to the Automatic Renewal Service. You authorize us to automatically deduct the applicable renewal fee from your payment account before the original subscription period ends unless you cancel before renewal. If you wish to stop renewal, you must cancel the Service before the current subscription period ends in accordance with the Automatic Renewal Agreement .

You agree that we may adjust subscription prices at any time due to changes in business strategy or for other reasons and notify users through the DuoPlus Pricing page . If you do not agree to a new price, you may cancel automatic renewal before the new price takes effect in accordance with the Automatic Renewal Agreement . Unless a price change is separately notified, the automatic renewal price generally will not exceed the price for the preceding subscription period, excluding promotional discounts.

6. Refund Policy

6.1 DuoPlus offers prepaid subscription plans, and no paid service is refundable. Please note that all payments are final.

6.2 In particular, additional “free environment” quota purchased by a user is an additional resource-capacity service intended to improve the free-user experience. Because system resources are allocated and reserved immediately upon purchase, and because this capacity expansion does not expire or correspond to a specific subscription period, the capacity expansion fee is non-refundable once payment succeeds.

7. Termination

7.1 This Agreement takes effect when you accept these Terms and remains in effect indefinitely until terminated by either party. DuoPlus may suspend or terminate your account or the Service at any time for any reason.

DuoPlus reserves the right to refuse the Service to any person at any time for any reason.

7.2 You may terminate your account at any time by contacting us through official customer support or at support@duoplus.net . Please note that, after termination, you may immediately lose access to certain parts of our website or Service. We may terminate this Agreement with you if:
