About LocalPatcher & Safety Guidelines

LocalPatcher does not distribute cracks or virus-infected files. We only swap language offsets transparently.

LocalPatcher does not modify game execution logic to distribute illegal cracks or malware. We are a localization utility tool helping users enjoy single-player games in their native language using official trainers. All patching operations occur locally in your browser, verifying the original file integrity and safely overwriting only the English text data sections.

1. Play in Offline Mode (Prevent Account Bans)

Launching a trainer while connecting to online multiplayer sessions may violate cheating policies and trigger permanent bans (such as Steam VAC bans). Always set your Steam launcher to Offline Mode before enabling any cheats.

2. Antivirus False Positives

Since game trainers use memory injection hooks to modify values, they are frequently flagged as threats by antivirus software (like Windows Defender). As long as you verify the clean original hash on our platform, you can safely add it to exclusions.

3. Back Up Save Files regularly

Memory conflicts can rarely occur during trainer operation, risking save file corruption. We highly recommend locating and backing up your local game save directories manually before using any trainer.

4. Verify Game & Trainer Versions

A mismatch between the game version (e.g., Steam v1.1.0) and the trainer version can lead to crashes. LocalPatcher checks the file size and SHA-256 hash to prevent mismatch patching, so make sure to upload the correct trainer build.
