Service terms
Updated September 16, 2026
Free tools
The current comparison tools are free and process files locally. You are responsible for reviewing matching rules, duplicate IDs and results before making business decisions. Keep your source files backed up.
Paid projects
A request is not an order. A project starts only after written agreement on its scope, deliverables, final price, timing and data-handling arrangements, followed by confirmed payment. Additional work requires a separate agreement.
Data and access
Use synthetic or anonymized examples initially. Do not send passwords, payment information or unnecessary personal records. Share project data only through a method agreed in writing. We will agree on access and deletion arrangements before any transfer.
Support
Contact cuiweifly@gmail.com about a project, a correction or an issue. These service terms do not remove rights that apply under mandatory consumer law.
