Local drafts
Personal tier boards, custom text, compressed image uploads, Daily progress and challenge drafts use browser localStorage. The application does not upload this data. Clearing site data removes it.
Share links
Built-in templates can encode the template ID, version, tier definitions and item positions in a URL fragment. The link does not contain image files or account data. A challenge fragment contains the owner's built-in board so both browsers can compare after the friend ranks the same items.
Custom images
Uploaded images do not enter a share URL. They travel only when you download a PNG or export a .tierlist.json file. Do not add sensitive images or text to a board you plan to send to someone else.
Future changes
If a later release adds public user content, accounts or analytics, this page must be updated before collection starts. Public UGC requires moderation, deletion handling and a separate retention policy.
