About IPVNN

IPVNN publishes short explainers on two subjects that trip people up for similar reasons: numbers, and the internet. Odds, percentages and offer conditions on one side; privacy and account security on the other.

How to read these

• Each piece covers one idea and shows the arithmetic or the reference.
• Some pieces link to material in Chinese on other websites. Those sites are responsible for their own content, and a link is not an endorsement.
• Nothing here is financial, legal or security advice for your particular situation.
