The OAuth request will be used to read the email of users who access the spreadsheet attached with the script.
The Script used to tally votes will take your email, and record it for each vote you cast in a hidden cell in the spreadsheet. Removing your vote will remove your email from that entry. Nothing else utilizes the information we collect.
Your information will not be shared, sold, or used for any purposes other than verifying voting activity on this sheet.
You can find the vote sheet here;
