Privacy Policy
1. Introduction
Tonal is a lightweight local AI style conversion app designed to help users transform their photos into unique artistic works with simple operations. Users can upload one photo, select from a variety of built-in templates, and use the app’s local AI technology to restyle the photo’s tone, texture, and atmosphere. We are committed to protecting your privacy and ensuring that your experience with Tonal is safe and secure. Tonal does not require an account to log in, so you can use all its features without providing any personal information. We do not collect any facial data, and all operations related to your photos are completed locally on your device.
All information is processed locally, and information is only retained on the user’s local device. When the user takes the initiative to delete the information, the information will be deleted, so the app does not collect any facial data. This commitment runs through all functions and services of Tonal, ensuring that your personal data and photo content are always under your own control. We understand the importance of privacy, so we have designed Tonal to avoid any behavior that may involve your privacy, and we will never engage in any activity that violates your privacy rights.
2. How Tonal Works
2.1 Local AI Style Conversion
Tonal uses local AI technology to complete all style conversion tasks. When you upload a photo to the app, the local AI model will process the photo directly on your device, without transferring any of your photo data to any external location. The local AI model preserves the composition of your original photo while restyling its surface, light, and texture according to the template you select.
During this process, we do not collect any facial data, and no part of your photo will be stored outside of your local device.
2.2 Photo Preview and Comparison
Tonal supports real-time preview of style conversion effects and comparison between the original photo and the converted work for the current generation. All preview and comparison operations are completed locally on your device, and no data related to these operations will be recorded or stored elsewhere.
We do not collect any facial data, even if your photo contains facial features, the local AI processing will only focus on style conversion and will not extract, recognize, or store any facial information. All information is processed locally, and information is only retained on the user’s local device. When the user takes the initiative to delete the information, the information will be deleted, so the app does not collect any facial data.
2.3 High-Definition Export
When you are satisfied with the style-converted work, you can export it in high definition without watermarks. The export process is completed locally on your device, and the exported file will be saved directly to your device’s local storage. We do not collect any facial data, and we will not retain any copies of your exported works. The exported works belong entirely to you, and you have full control over their use, storage, and deletion.
3. Data Retention and Deletion
3.1 Local Data Retention
All data generated when using Tonal, including the photos you upload, the style-converted works, and the settings you select, are only retained on your local device.
Tonal does not store any of your data in any external location, and we do not collect any facial data at any time. The retention period of your data depends entirely on your own operation—you can keep the data on your device for as long as you want, and there is no mandatory retention period set by Tonal.
3.2 Data Deletion
You have the right to delete any data related to Tonal on your device at any time. When you take the initiative to delete a photo, a converted work, or any other data generated by the app, the data will be completely deleted from your local device immediately.
All information is processed locally, and information is only retained on the user’s local device. When the user takes the initiative to delete the information, the information will be deleted, so the app does not collect any facial data. After deletion, the data cannot be recovered through Tonal, and we will not be able to retrieve or restore any deleted data because we never stored it in the first place. We do not collect any facial data, so even if you delete photos containing facial features, there is no risk of facial information leakage.
