Question: Is it easy for people to find "public" google sheets/docs?

Context: Storing some semi-sensitive data (individual user info, of non-sensitive nature) for an app beta-test in google sheets. Planning to migrate to some DB in the future, but for now, just using JavaScript to pull the data directly from the google sheets (since there are visualizations being dynamically updated by the sheets).

Answer: 
Yes, it's easy to get information. Search engines may index and cache the information. Then, there are bots, crawlers and scrapers. Do NOT put (semi)sensitive information in public. Implement [google-oauth](/questions/tagged/google-oauth "show questions tagged 'google-oauth'") properly with [google-sheets-api](/questions/tagged/google-sheets-api "show questions tagged 'google-sheets-api'") to get information. You can also use [service-accounts](/questions/tagged/service-accounts "show questions tagged 'service-accounts'")
Don’t make it public unless you want the public to see it. Use oauth to access.
