Local data and support

Numpad Remapper — Local Data and Support Information
Buyer documentation / 2026-10-20

This document describes the Windows portable and Microsoft Store editions.
See the LICENSE.txt included with your edition for the complete
Japanese/English license terms.

Stored information

Settings include registered application identities and paths, profile and
user-defined names, key assignments and the keyboard layout. The display
language is stored separately. Recovery history and related files may remain
as settings are saved or updated.

Settings and display-language locations

The portable edition saves settings in:
%LOCALAPPDATA%\NumpadLeftHandDevice

On a first Store installation, settings normally use this Store-specific folder:
%LOCALAPPDATA%\Packages\UrushigusaSoftware.NumpadRemapper_2w91vb42qzcdm\LocalCache\Local\NumpadLeftHandDevice

If portable-edition settings already exist, the Store edition shares the
settings in the following folder. Changes made in the Store edition are also
saved to those shared settings:
%LOCALAPPDATA%\NumpadLeftHandDevice

In either folder, settings use localization-r14\settings.json and the display
language uses localization-r14\display-language.json.

Diagnostics
Startup and operating diagnostics may be saved in the diagnostics subfolder
of the locations above.

Startup failures use startup-error.txt; operating records include per-run
jsonl files.

Operating diagnostics include run and version identifiers, process IDs,
times, state changes and stop, release and recovery results. Some feature or
diagnostic paths may include key-identification or output-result codes.
Startup errors and application settings may include paths and user-defined
names.

Processing and transmission

Assignment handling, foreground-application identification and input
conversion run on the device. The OS, third-party components and
purchase/download services may communicate over the network. Purchases,
payments, distribution sites and contact services you choose to use are
subject to their own disclosures and terms.

Contacting support

You choose whether to send settings or diagnostics. You may begin with the
product name, version, steps and notice text; artwork, passwords or secrets
are not required. Before sending a file, check application names, paths and
personal names and provide only what is necessary. Redact a support copy
rather than changing the live settings original.

Retention and removal

Portable edition

Deleting the extracted app folder leaves settings, history and diagnostics in
place. Other portable versions share that data, so check whether it is needed
and retain a backup before deleting it.

Microsoft Store edition

Uninstalling removes settings and the display-language file in the
Store-specific area. Settings and language files shared with the portable
edition remain. Manually deleting shared settings also affects the portable
edition.

Exit the app completely before backing up any settings, history or diagnostics
you want to keep. Paste each path above into File Explorer's address bar and
copy each folder that exists to a separate location. If both exist, keep
separate backups. See the Guide.en.txt included with your edition for restore,
update and exit procedures.

Uninstall through Windows Settings > Apps. Do not remove or change settings
or diagnostics while the app is running.
