Célia Castelo Ads Tool
Internal tool documentation · Last updated: September 14, 2026
Célia Castelo Ads Tool is an internal tool built and used by one person, Celia Castelo, to manage her own Google Ads accounts through the Google Ads API. It is not a product. It is not sold, licensed, distributed or offered to any third party. It exists only to save time on repetitive work inside accounts that the owner runs and pays for herself.

2. Business model
The owner runs her own content websites and promotes products as an affiliate, and she teaches SEO in Portuguese at celiacastelo.com.br. Revenue comes from those activities, never from the tool. The tool generates no revenue of its own: it is not licensed, not resold, not published, and has no users other than the owner. There is no agency, no client and no external party of any kind.
3. What the tool does
- Reads performance data from the owner's own accounts: campaigns, ad groups, keywords and ads.
- Creates and updates Search campaigns for the owner's own websites.
- Adds and pauses keywords and negative keywords.
- Adjusts budgets and bidding settings inside the owner's own accounts.
- Produces internal reports the owner reads to decide what to change.
Every write operation is reviewed and approved by the owner before it is applied. Nothing is published automatically without human review.
4. Google Ads API services used
- Campaign Creation
- Campaign Management
- Reporting
Campaign type: Search only. No Display, no app campaigns, and no app install or app event tracking.
5. Accounts and scope
The tool accesses only accounts owned by the applicant and linked under the manager account listed above. It never accesses accounts belonging to anyone else. Access uses OAuth 2.0 credentials issued to the owner's own Google Cloud project, stored locally on her personal computer with restricted file permissions, and never shared. Access can be revoked at any time at myaccount.google.com/permissions.
6. Expected API usage volume
Fewer than 100 API operations per day. The tool runs on demand, manually, when the owner is working on her campaigns. There is no continuous polling and no scheduled bulk process.
7. Intended audience
One person: the owner. The tool has no sign-up, no login screen, no interface for other people and no distribution channel. It runs locally on her own machine.
8. Data handling and Limited Use
Data obtained from the Google Ads API is stored locally, is never shared with third parties, is never sold or republished, is not used for targeted advertising and is not used to train artificial intelligence models. Full details are in the privacy policy.
Celia Castelo's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
9. Compliance
The tool is used only for advertising that complies with Google Ads policies. It makes no claims of its own, and all ad copy is written and reviewed by the owner before it is submitted.
