About Vipima

Vipima — "measuring instruments" in Swahili — is an independent project by Jean Knapik, a software engineer building data systems for advertising transparency.

The project collects the complete Meta Ad Library archive for elections it covers, preserves it in append-only snapshots (the archive itself is unstable — ads and advertisers disappear between pulls), and publishes what the data shows: who advertises, what they disclose, what the platform withholds, and how campaigns change between cycles.

Everything published here states its method and its limits — see the methodology. Corrections and challenges to any figure are welcome.
