To use the module, you need to purchase a BitEdit USB protection key . The key can be purchased in our store. An unlimited number of modules can be purchased for one key.
Updates of descriptions for new software versions within the module are free.
Module activation is performed within 1 hour on business days (usually 10-15 minutes). Activation may be delayed on weekends and holidays (up to 2 hours).
Only the serial number of the key and email are required to activate the module.
1. No Refunds or Modifications for Digital Licenses
Activated modules or licenses cannot be returned or refunded.
If an incorrect key or device number is entered by the customer, the purchase is not eligible for return.
Licenses cannot be modified, transferred, or reissued for another device under any circumstances.
2. Irreversible Order Processing
After the order status changes to “Waiting for activation”, the data has already been sent to the developer.
From this point onward, the order cannot be canceled, edited, corrected, or refunded.
3. Responsibility for Software Functionality
Our store is not responsible for the functionality, performance, or declared features of any software module.
We do not guarantee the listed functions because we are not the developer.
4. Accuracy of Product Information
Module and script descriptions are provided directly by the manufacturer.
IOBD.io is not responsible for any inaccuracies, missing details, or differences between the description and actual operation.
In disputed situations regarding functionality or listed features, the customer must contact the manufacturer.
5. Customer Responsibility for Installation
IOBD.io sells professional automotive diagnostic software and equipment.
Installation, setup, configuration, and compatibility checks must be performed by the customer.
We do not provide remote installation, programming, or setup services unless explicitly stated otherwise.
6. Required Technical Knowledge
These products are intended for users with basic technical knowledge in automotive diagnostics.
The customer is fully responsible for understanding the installation process and using the software and hardware correctly.
7. No Liability for Incorrect Usage
IOBD.IO is not responsible for issues caused by:
incorrect installation
unsupported or incompatible hardware
improper configuration
third-party interference
