Terms of use

Responsibility for web application accuracy

Appizy provides a conversion service of a spreadsheet into Web Application written in HMLT, JavaScript, and CSS. The generated Web Application code is provided “as is”, without warranty of any kind, including but not limited to graphical element or calculations.

You must check the output accuracy of your Web Application. Although we are pleased to help you fixing calculation bugs and divergence, we cannot be held responsible for calculation errors in the generated application.

The conversion Service is constantly evolving. In case you write additional code to interact with the Web Application be sure to test the compatibility of your code with every newly generated Web Application. Appizy cannot be held responsible in case the generated code is not anymore compatible with the additional software you wrote.

Responsibility for data

We do not make backups of your files for privacy reasons. Always keep a copy. While we try to ensure that the service is error-free, we cannot guarantee that your files will not be damaged, deleted, or lost.

You acknowledge that you have a copy of all files and Appizy will not be responsible for any failure caused by files, sent to Appizy.

Appizy cannot be held responsible for any data loss or incompatibility while using the Web Application. This is also valid if you use Appizy App Embed plugin provided for WordPress or if you use the ability to save data locally as JSON.

Web application protection

The Web Application generated by Appizy is by default a client-side application. It runs in the visitor browser. Therefore, all the formulas are downloaded on the client browser. Even though they are not directly seen by the visitor, this could be reverse-engineered by analyzing the source code of the application.

If your original spreadsheet contains a business-critical or secret formula, we advise you to secure your application behind authentication on your website. You can also use applications with server-side calculations if you want to hide the formula.

Vendor libraries

The web application relies on JavaScript libraries delivered by third-party. These are called Content Delivery Network or CDN.

These third-party providers are chosen for their reliability. Nevertheless, Appizy cannot be held responsible in case one of this third part CDN would come to stop or change.

We claim no intellectual property rights over the material you provide to the Service. Your files uploaded remain yours.

Do not use our services and intellectual property for any form of infringement. You are the only responsible for the data (e.g. files) which it sends to the Appizy service. Appizy does not monitor customer content.

Subscription management

We use the payment gateway called Fastspring to handle payment and subscription. Fastspring acts as an official reseller of Appizy subscriptions.

Trial and paid plans

When you create an account on Appizy site you automatically get a 30 days trial period to test the conversion of your file. You can check the quality of the conversion, but you will not be able to download the code generated. To unlock the download functionality you need to subscribe to a paid plan.

Appizy offers 3 different plans on a monthly or yearly billing cycle. Every subscription gives access to the ability to download the generated code of the Web Application.

Appizy, in its sole discretion, has the right to add, update, or remove some of the conversion features linked to a specific plan.


Subscription cancellation should be done using Fastspring dashboard. To access it click on the blue link “Manage Your Orders” in the checkout email you got from Fastspring and follow the steps indicated by Fastspring. In case you have any questions, do not hesitate to contact us.

Appizy, in its sole discretion, has the right to suspend or terminate your account and refuse any current or future use of the Service, for any reason at any time.
