I operate Columnproof. Contact me at socialreminderinfo@gmail.com. These terms apply to this free browser application.

Using the workbench

You may use the application for personal and professional review work. You retain ownership of your input files, project notes and exported records. Only open files you are entitled to use and share exports with the intended recipients.

Local work and backups

Your project is saved in this browser. I cannot recover a deleted project. Export a complete checkpoint regularly, particularly before clearing browser data, changing devices or moving to a different website address.

Review limits

The workbench compares observed structure; it does not certify data quality, compatibility or a safe production release. Review its findings and the limitations before relying on an output. It is provided as is, to the extent permitted by applicable law.

Payment and changes

This release is free and does not accept payments. Any future paid offering will state its price and terms before a purchase. Continued free availability or a particular future feature is not guaranteed.

Governing law

These terms are governed by the laws applicable in Ontario, Canada, without limiting mandatory rights that apply where you live.
