About this app

MarkIn is an application focused on image watermarking, suitable for users who need to quickly take photos, import images, and add watermarks.

Users can directly take photos with their camera or import images from their device's photo album and files, completing the watermarking process within the app. All image processing is user-driven, with a clear and intuitive workflow.

Without logging in, users can still use basic functions such as taking photos, importing images, and watermarking; the app does not collect or upload any user data.

If users log in to their accounts, they can enable the "Image Upload" function to upload watermarked images to the server for storage or later use. Images are only transmitted when the user actively selects to upload.

MarkIn is committed to providing a simple, secure, and user-friendly image watermarking experience; all data usage is for the purpose of functionality provision and service maintenance.
It allows users to add watermarks to photos or imported images, and upload the images to the server after logging in.
