We respect your privacy. This Privacy Policy explains what information we collect, how it is used, and how it is protected when you use SheetAI / TukoAI.
When you register or log in using Google Sign-In or email, we collect your email address and necessary account information solely for identification, authentication, and account management purposes.
When you use the service for analysis, we may collect spreadsheet names and structural data characteristics, such as the number of columns, data formats of each column, and the general type of the table. Spreadsheet names are used to help guide correct file uploads or analysis reconstruction, while structural characteristics may be processed or encrypted before being used to generate analytical patterns via AI models.
To provide analytical and generative capabilities, we may submit portions of data related to your request to third-party AI service providers, such as OpenAI, for processing. These data are used only to complete the requested task, are not intended to identify you, and remain your property.
You retain full ownership of all data you upload or provide. TukoAI does not claim ownership of your data, and data usage is limited to providing and improving the service.
We implement reasonable technical and organizational measures to protect your data. We do not intentionally access, sell, or disclose your original data content, and we aim to minimize risk during storage and processing.
You may manage whether your conversation data is used for system improvement and whether you receive email notifications through your account settings. We respect your choices and provide corresponding controls.
This Privacy Policy may be updated as the product evolves. Continued use of the service after updates take effect indicates acceptance of the revised Privacy Policy.
