Why we publish the formulas
A number from a black box is hard to trust and impossible to explain to the other side of a deal. Each tool shows exactly how its result is calculated, so a creator can justify a quote to a brand, and a brand can show a finance team how a campaign was judged. Where a tool relies on an assumption, such as a base price per 1,000 views, it says so on the page.
Your data stays on your device
The calculators work on the numbers you type in. Nothing is sent to Kollabary; your last inputs are remembered only in your own browser so you don't have to retype them. Kollabary has no Instagram or YouTube API connection and does not read your accounts.
