Your public profile

Anyone with the link (or finding you on the leaderboard) sees: your display name, your `@username`, your avatar, your level and total XP, your Founding Explorer number if you have one, your followers + following counts, and any public trails / quizzes you’ve created (with their progress and completion status). The follow graph is also public — your followers and the people you follow can be browsed by anyone.

Pro adds the customisation layer on top: cover image (or gradient preset), bio, and up to 6 featured trails. If you downgrade to Free, those Pro-only customisations are kept in your account (so re-subscribing brings them back) but hidden from public view.

In-progress trails, quiz attempts, duel transcripts (the score is public; the question history is not), AI tutor chats, billing info, email address, learning motivation, interests, color theme / color mode, notification preferences, and any trail or quiz marked private (Pro only) are visible only to you.

Free picks from the curated preset library (Yoonle Fun Emoji collection); if no preset is picked yet, a deterministic emoji fallback derived from your user id is rendered. Pro unlocks two extra paths: uploading a custom image (resized to 256×256 WebP, EXIF stripped, automatically screened by Azure AI Content Safety) OR using your OAuth photo (Google / Apple) via the "Use my Google avatar" pill.

Free → Pro → Free downgrade preserves any previous custom upload in storage so the "Bring back your avatar" prompt has data to show if you re-subscribe — but the upload itself is invisible while on Free; your avatar reverts to the last preset (or the deterministic fallback) until you upgrade again.

The banner at the top of your profile defaults to a neutral preset gradient. Pro can either upload a cover image (same content-safety pipeline as avatars) or pick from the preset gradient set. Avatar and cover uploads have separate daily caps — 10 avatar uploads/day and 5 cover uploads/day per user.

A short bio of up to 280 characters appears under your name. It’s a great place to mention what you’re learning right now — followers see it as the headline answer to "what is this person into?"

You can feature up to 6 of your public trails on your profile in any order you like. This is the curated portfolio Explorers actually browse — keep your best three to six pinned, reorder when something better lands.

Featured trails must be public AND owned by you. The settings UI silently drops any pick that doesn’t satisfy both rules at save time, and the public-profile renderer auto-skips trails that have since been made private.

Settings → Account → Public profile. The picker for featured trails has a search box and pages through your public catalogue 5 at a time so you can find pre-selections fast even with hundreds of trails. Reordering is one-tap with up/down arrows.

Every public profile has a `⋯` kebab menu next to the Challenge button with two safety actions : Block and Report. Both are available on Free and Pro — they’re not gated.

Block is symmetric — once you block someone, neither of you can challenge the other to a duel, the Challenge button hides on both profiles, the search index filters you out of each other’s results, and you’re excluded from each other’s Quick Match pool. The other user is not notified. Report sends a private signal to the Yoonle safety team for any abuse or harassment ; we aim to triage within 24 hours.

Manage your blocks any time in Settings → Account → Blocked Explorers — the page lists everyone you’ve blocked with an "Unblock" button on each row. Unblock takes effect immediately and reopens the Challenge button on both sides.
