Depending on the data and lawful basis, you may ask for access, correction, erasure, restriction, or portability, and you may object to processing based on legitimate interests. These rights are not absolute—for example, a necessary moderation or security record may lawfully be retained.
Email matcha@feksake.com with your Discord user ID and the request. Discord Developer Mode lets you right-click your name and choose Copy User ID. The operator may ask for proportionate proof that the account is yours and aims to respond within the legal time limit, normally one month.
Erasure currently anonymises the cached profile and nickname, clears automod excerpts and ticket subject/link fields, and deletes reminders, AFK records, invite attribution and dashboard sessions. Moderation cases, staff notes, audit/security records and per-server economy, level and feature history may be retained where still necessary. A ticket transcript already posted into a Discord staff channel is controlled in Discord and must be requested from that server's staff.
You have the right to object to processing based on legitimate interests. You can also complain to the Information Commissioner's Office. You do not have to contact Matcha first.
