Try the Chrome Web Store Privacy API

- `disclosure` is the developer's data-use statement; `collects_data` reflects whether it declares collecting or using data; `data_collected` lists the data categories it declares handling (empty when it collects nothing); `declarations` is the list of standard data-handling declarations the store shows; `privacy_policy` is the developer's privacy-policy link. - An unknown item id returns a typed not-found error (HTTP 404). A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503). Example response (a data-collecting extension): ```json { "code": 200, "msg": "OK", "data": { "id": "kbfnbcaeplbcioakkpcpgfkobkghlhen", "name": "Grammarly: AI Writing Assistant", "collects_data": true, "data_collected": [ "Personally identifiable information", "Personal communications", "Location", "User activity", "Website content" ], "disclosure": "Grammarly … has disclosed the following information regarding the collection and usage of your data.", "declarations": [ "Not being sold to third parties, outside of the approved use cases", "Not being used or transferred for purposes that are unrelated to the item's core functionality", "Not being used or transferred to determine creditworthiness or for lending purposes" ], "privacy_policy": "https://www.grammarly.com/privacy-policy", "url": "https://chromewebstore.google.com/detail/kbfnbcaeplbcioakkpcpgfkobkghlhen" } } ``` An extension that collects nothing returns `collects_data: false` and an empty `data_collected`, with a "will not collect or use your data" disclosure.
