1. Who MESOLANE Is
MESOLANE is an independent, unofficial community market and item reference. It is not affiliated with, endorsed by, sponsored by, or operated by Nexon or Discord.
2. Information We Collect
MESOLANE uses account and profile details, listings, favorites, reports, security records, and request information to run the site. Screenshot recognition processes images you choose to upload or paste. We do not ask for your postal address, phone number, or payment-card details.
3. Information Received Through Discord
Discord sign-in requests the identify and email scopes. Supabase Auth may retain your email for sign-in, but MESOLANE does not copy it to the public profile or show it in marketplace pages.
Discord sign-in also requests the guilds.join permission to join the MESOLANE Discord server once. MESOLANE keeps a private record of your Discord user ID and the time membership was observed or an automatic join was attempted, so signing in again will not automatically add you after you leave. Discord permission approval remains required. A Discord membership failure does not cancel your site sign-in.
MESOLANE uses your Discord user ID, username, display name, and avatar when available for your profile, listing ownership, and contact links. OAuth tokens are not shown in marketplace pages.
Discord operates separately under its own Privacy Policy. Discord does not endorse MESOLANE.
4. Marketplace Information
Listings may show the item, BUY or SELL side, price, quantity, stats, IGN, trade method, location, notes, and activity dates. We use these details to show, search, manage, and moderate listings.
5. Favorites and Account Features
Signed-in favorites are associated with the user's profile in Supabase. Guest favorites, recent item searches, item-view submission deduplication timestamps, profile preferences, and legacy local marketplace backups can be stored in the browser. Listing-credit balances and ledger records are account-scoped and are used to operate listing limits.
Popular Items uses only daily aggregate item-detail view counts. MESOLANE does not store a user ID, Discord ID, IP address, cookie value, browser fingerprint, device identifier, or individual browsing history in that aggregate.
6. Account Security and Human Verification
MESOLANE maintains private account-trust information such as human-verification time and source, server-derived Discord account creation time, and any temporary trading restriction. Cloudflare Turnstile may process a verification request to help reduce automated abuse. Cloudflare applies its own Turnstile Privacy Addendum.
7. Reports and Moderation
Signed-in users may submit a report reason and optional note. MESOLANE stores the reporter's internal profile reference and an immutable snapshot of the reported listing for moderation integrity. Report identities, private evidence, review state, and moderation audit records are not public marketplace data.
8. Technical and Log Information
Hosting, database, security, and network providers may automatically process request metadata such as IP address, user agent, device or browser information, timestamps, requested URLs, response status, and security signals. MESOLANE may use application and infrastructure logs to operate, diagnose, and secure the service.
9. How We Use Information
- Provide authentication, profiles, listings, favorites, Stores, contact tools, and Price Insight.
- Apply listing-credit, account-age, human-verification, rate, and abuse controls.
- Respond to reports, support requests, privacy requests, and intellectual-property concerns.
- Maintain reliability, diagnose errors, measure basic page use, and protect users and the service.
10. Public Information
Marketplace participation is public by design. Public pages can show a trader's Discord user ID in a profile URL or contact link, Discord username, display name, avatar, IGN, joined month and year, active and completed listings, listing content, Store and trade details, and listing timestamps. Do not place private or sensitive information in an IGN, listing note, Store detail, or other public field.
11. Private Information
MESOLANE does not publish OAuth credentials or tokens, authentication cookies, site-access credentials, account-trust records, listing-credit ledger details, favorite ownership, reporter identity, internal moderation evidence or audit records, or raw Price Insight segments containing owner and listing identifiers. Aggregate Price Insight results are public.
12. Service Providers
MESOLANE uses third-party providers to operate the service: Discord for authentication and contact links; Supabase for authentication and database services; Vercel for hosting; Cloudflare Turnstile for human verification; and Google Analytics for limited page-view measurement when production analytics is configured. These providers process information under their own terms and privacy practices.
13. External Links
Links to Discord and other websites leave MESOLANE. The optional Support MESOLANE link opens Buy Me a Coffee. Any payment is handled by Buy Me a Coffee and its payment providers; the current hyperlink integration does not send payment-card details to MESOLANE.
14. Cookies and Local Storage
Strictly necessary cookies support Supabase authentication and OAuth state, and the private-preview access gate when enabled. These cookies are used for session and security functions.
Browser local storage can retain guest favorites, recent searches, item-view submission deduplication timestamps, profile IGN preferences, and legacy local listing, completed-trade, and credit backup data. The deduplication timestamp prevents the same browser from repeatedly submitting the same item view during a short window; it is not uploaded as an identifier. You can clear local storage through browser controls, although doing so can remove local preferences or backup information.
When basic Google Analytics is enabled on mesolane.gg, Google's tag may use analytics cookies or similar identifiers. MESOLANE sends sanitized page paths and excludes authentication, verification, admin, API, private-preview, and local fixture routes; public profile identifiers are replaced with a generic path. Advertising personalization and Google signals are disabled in the current integration.
15. Advertising
MESOLANE does not currently integrate Google AdSense or another advertising platform. MESOLANE may display advertising in the future. If advertising services that use cookies or similar technologies are introduced, this Privacy Policy and any required consent controls will be updated before or when those technologies are enabled.
16. Data Retention
We keep information as needed to run and secure the site, handle reports and disputes, and meet applicable obligations. Not every category has a fixed retention period. Browser-local data stays until you clear it or the browser or site replaces it.
17. Account Deletion and Requests
MESOLANE does not currently provide an instant self-service account-deletion workflow. To request access, correction, or deletion of account information, email MESOLANE. Some records may need to be retained or de-identified for security, fraud prevention, moderation integrity, dispute handling, or legal and operational obligations. Requests are reviewed individually and are not guaranteed to be completed immediately.
18. Security
MESOLANE uses access controls, row-level database policies, private server configuration, signed sessions, human verification, request controls, and other technical measures intended to protect information. No online service can guarantee absolute security. Users remain responsible for protecting their Discord account and must never share passwords or verification codes.
19. International Users
MESOLANE and its service providers may process information in countries other than your own. Privacy protections and legal requirements can differ by location. Use MESOLANE only if you are legally permitted to do so where you live.
20. Children and Age
MESOLANE has not adopted a separate numerical minimum age. You must be legally permitted to use MESOLANE, Discord, MapleStory, and any other connected service under the rules that apply to you. If you believe a child has provided information contrary to applicable requirements, contact MESOLANE.
21. Changes to This Policy
This policy may be updated as MESOLANE's features, providers, or legal obligations change. The date at the top will be revised when an updated version is published.
22. Contact
For privacy, account-data, support, or intellectual-property questions, contact MESOLANE by email. MESOLANE does not publish a private home address or phone number.
