This page could not be found. sukadia.dev Everyone Votes Privacy Policy Everyone Votes is an application on Discord that delivers and tallies daily polls to Discord servers. By being a user, you agree to the following use of your data:
What We Store By voting on a poll with Everyone Votes, we store: This data is stored for up to 24 hours, and is wiped every day at UTC midnight.
A cumulative count of the number of votes for each poll option is saved indefinitely.
By setting up Everyone Votes, we store: - The server id, poll channel ids, and current poll messages
- Config settings
This data is stored for as long as Everyone Votes is setup within the server.
By adding server-wide polls on Everyone Votes, we store: This data is stored up until the results are tallied for it. Moderators can also manually remove the poll by using the corresponding command.
In summary, I don't use your data for anything malicious, just for getting poll result counts.
Removal of Data Server data is erased once Everyone Votes is kicked from the server. Any server moderator can kick the bot to trigger this erasure.
User vote data is erased at UTC midnight every day. Since user vote data lasts such a small window of time, erasure requests cannot be fulfilled for this data.
Contact If you have questions or concerns about these terms, please join the support server on Discord, or email contact@sukadia.dev .
