The record

Purpose: Aduku Stacker combines focus-bracketed photographs into one sharp image for macro, product, landscape, and microscopy photography.
Merge methods: It offers five merge methods: Wavelet, Pyramid, Weighted, Hybrid, and Depthmap.
Image processing: The default workflow processes images at 16-bit, uses 32-bit floating-point merge math, and supports memory-bounded batching for deep stacks.
Alignment: Automatic alignment includes feature matching and subpixel refinement, with options for focus-breathing correction, homography, mesh warp, and manual alignment seeding.
Import and export: It supports JPEG, PNG, TIFF, BMP, HEIC, and DNG import, plus JPEG, PNG, TIFF, linear DNG, and depth-map export; proprietary RAW import may require Adobe DNG Converter on macOS.
Retouching: Users can paint from aligned source frames, erase strokes, and undo or redo retouching; the app does not yet have a clone tool.
Privacy: The app processes photographs locally and says it does not upload images, create user accounts, or transmit analytics or telemetry.
Connectivity: The FAQ says the app needs no internet connection for image processing.
Support: The maker lists [email protected] for questions and support, and says it has no obligation to provide support, maintenance, or updates.
System requirements: The stated requirements are macOS 13 or later or 64-bit Windows 10/11; 8 GB RAM is sufficient for most stacks and 16 GB is recommended for deep 16-bit RAW stacks.
Command line: The focus-stacking engine also ships as a command-line tool with parameter flags for scripting batch processing.
Maker: The terms identify the publisher as Suriyanarayanan R Srinivasan of Aduku Labs, and the site says the product is made in India.
