The banner is not a bug — it's a deliberate security feature by Google. End users will always see a disclaimer when running unverified or user-created scripts.
If you are building a tool for yourself or colleagues within the same company or school domain, the solution is simpler. Google allows administrators to trust internal apps without full verification.
The warning does not mean your app is dangerous. It simply means Google has not yet verified your identity and compliance with their API policies.
No — you cannot remove that specific line entirely if you are using a standard, unverified app. Google intentionally shows it to inform users that the app is not from a verified publisher. The banner is not a bug — it's
However, you can replace it with your own brand name and remove the “Google Apps Script user” part by completing Google’s App Verification process.
If you are finding documents named "Paper" appearing in your Google Drive, or receiving emails with that subject line, you likely have an active Trigger set up in Google Apps Script.
How to stop the creation:
Google Apps Script (GAS) allows developers to build lightweight business applications integrated with Sheets, Docs, Gmail, and Drive. When a GAS project is deployed as a web app (executed as either the user accessing the app or as the developer), Google appends a footer line that states: “This application was created by a Google Apps Script user.”
For organizations building internal tools or customer-facing applications, this message can appear unprofessional, cause confusion among end users, or conflict with branding guidelines. This paper investigates the feasibility of removing this notice and presents documented alternatives.
Before removing the warning, you must understand its origin. Google introduced this security measure to protect users from malicious or poorly configured third-party applications that request access to their Google Drive, Gmail, Sheets, or other sensitive data. No — you cannot remove that specific line
When you create an Apps Script project and deploy it as a web app or an add-on, Google automatically classifies it as an unverified app unless you meet specific criteria.
Even after verification, many developers fail to remove the warning because of these errors:
| Mistake | Why It Fails |
|---------|---------------|
| Using default GCP project | Cannot be verified. Must use your own project. |
| Privacy policy missing or invalid | Google rejects verification. |
| Sensitive scopes not justified | Vague descriptions cause rejection. |
| App still deployed under old version | You must create a new deployment after verification. |
| Access set to “Only myself” | External users won’t see the verified status. |
| Using @gmail.com as owner | Verification is impossible. | If you are finding documents named "Paper" appearing
