How we source data
Prices and plans
Every price, usage limit and plan detail comes from the vendor's official pricing page or documentation. Each article states the date we checked it and lists its sources at the end. If an official page changes, the official page wins.
Untested items
Anything we have not measured ourselves is marked TBD. We do not estimate or invent numbers.
Third-party data
When we cite third-party tests we name the source and do not present them as our own results.
Corrections
When we find an error or outdated detail, we update the article and its "Last updated" date.
