What GasFact is
GasFact is an internal tool operated by its owner to plan, write and publish small content websites. It has one user: the operator. It is not offered to the public and has no visitors' accounts.
Data the app touches
- The operator's own Google account, through OAuth, to read Keyword Planner data from the operator's own Google Ads account (search volumes, competition and bid estimates for keywords). The app only reads; it never creates, edits or runs ads.
- When the operator enables it, read-only reports from the operator's own AdSense account and Search Console properties, to compare how the operator's sites perform.
- Public, aggregate data from Wikipedia page views and YouTube search results, with no personal information.
- The operator's own domains on Vercel, to attach them to the sites the app publishes.
The app does not collect, store or process personal data of third parties. The OAuth tokens it holds are stored as environment variables on the hosting platform, are used only for the calls above, and can be revoked at any time from the Google account's permissions page.
Google user data
GasFact's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Data obtained through Google APIs is used only for the operator's own research and reporting inside the app. The one transfer that happens: keyword texts and their monthly search volumes from Keyword Planner are included in the prompt the app sends to its AI provider (Anthropic) when it drafts the topics and domain ideas of a niche. No Google data is sold, used for advertising, or shared with anyone else.
Retention
Keyword metrics from Keyword Planner are used for up to 30 days after they are fetched and then fetched again. YouTube data older than 30 days is deleted before each explorer run. Wikipedia page-view aggregates and the monthly calibration records (earnings, page views and clicks per site) are kept as long as the operator finds them useful. The operator can delete any of it from the database at any time.
