Privacy policy for the WIA and SmileStory MCP servers (English)
1. Who we are and what this covers
SmileStory Co., Ltd. ((주)스마일스토리, business registration no. 109-86-17229, 5F #511, 21 Magokjungang 6-ro, Gangseo-gu, Seoul 07801, Republic of Korea; “we”) operates the Model Context Protocol (MCP) servers listed below. They let an AI app such as Claude call our tools on your behalf.
This policy covers only these MCP server addresses (the /mcp endpoints). Each website and any account you create there is covered by that service's own policy and by the SmileStory privacy policy.

2. What we receive and collect
2.1 Tool requests
When your AI app calls a tool, it sends us the tool name and the values it chose for that tool, for example search words, a postal address, a public web page address or a piece of text to convert. We need these values to produce the answer. We do not receive your whole conversation or your AI account details unless your AI app puts them into a tool request. The servers without sign-in do not ask for your name, email address or any account.
2.2 MCP usage log
Every server writes one short line per request so we can count real use and tell automated crawlers apart. Each line contains only:
- the time of the request;
- the server name and the MCP method (for example
initialize,tools/list,tools/call); - the AI app name and version that the app reports when it connects;
- the tool name, for tool calls;
- the first 90 characters of the User-Agent header;
- a 10-character caller code made by one-way hashing the connecting IP address together with the date. It changes every day, so it cannot be used to follow a caller across days, and the IP address itself is not written to this log.
The usage log does not contain tool inputs, tool results, API keys or raw IP addresses.
2.3 Web server access logs
Like any website, our web servers keep standard access logs: the connecting IP address (usually your AI provider's server rather than your own device), time, requested path, response status and size, referrer and User-Agent. Request bodies, where tool inputs travel, are not logged. For some tools, our MCP server passes your search words or coordinates to the same service's own web API inside a URL; those internal requests are logged with our own server's address, not yours. If you add an API key to a server address as ?key=…, the key can appear in the access log; use an Authorization header where your app supports it.
2.4 Abuse protection and caches
To prevent abuse, some servers count requests per IP address in memory or in a short-lived cache. These counters are not part of any log and expire within 24 hours. Identical requests may be answered from a short in-memory cache (up to 1 hour). WIA Address keeps copies of geocoding answers on disk to reduce calls to third-party map services.
2.5 Data that specific tools store
- WIA A11y Checker — a check saves the result (the public page address you asked about, the score and the issues found) under a result ID. Anyone who has the result ID can look it up. Our automated browser visits the page you name.
- WIA360 —
run_probeandscore_sessionrecord the scoring outcome: probe and variant, verdict, axis, scoring signals, language and the session reference your AI app generates. The full reply text you submit is scored and not stored.get_matchrecords anonymous match statistics (score and grade) without any identifier. - MusicCheck and WIA Motion — these work with your account on those services. Files you submit, screening reports, video campaigns and credit use are stored in that account under that service's terms.
- All other servers (The Korean Today, WIA Address, WIA Braille + WIA Talk, WIA Code, WIA GIL, WIA Music, WIA Standards, WIHP, WIA Wisdom) are read-only lookups and store nothing beyond sections 2.2–2.4.
3. How we use it
- to answer the tool request you or your AI app made;
- to keep the service secure and available, including rate limits and investigating abuse;
- to understand overall usage. Our operators receive a daily summary with counts only (calls per server, tool and AI app name).
We do not sell your data, use it for advertising, build profiles of you, or use your tool inputs to train AI models.
4. Sharing with third parties
- Hosting: our servers run on Oracle Cloud Infrastructure in Tokyo, Japan. Data described here is processed and stored there.
- WIA Address: the address text you send goes to the Korean government road-name address service (business.juso.go.kr), OpenStreetMap Nominatim and the Google Maps Geocoding API so that the address can be looked up and translated.
- WIA A11y Checker: the website you ask us to check receives visits from our checker.
- Daily summary: the count-only summary in section 3 is delivered to our operators through Telegram. It contains no tool inputs, IP addresses or caller codes.
- Legal requests: we disclose information only when Korean or other applicable law requires it.
No other third party receives data from these MCP servers.
5. How long we keep it
| Data | Kept for |
|---|---|
| MCP usage log (2.2) | 90 days, then deleted automatically |
| Web server access logs (2.3) | 14 days, then deleted automatically |
| Abuse counters and in-memory caches (2.4) | Up to 24 hours (counters) and up to 1 hour (in-memory caches) |
| WIA A11y Checker results, WIA360 scoring records (2.5) | Until you ask us to delete them |
| MusicCheck and WIA Motion account data (2.5) | As set out in that service's terms, or until you delete your account |
6. Your choices and rights
You can disconnect a connector at any time in your AI app. You may ask us to access, correct or delete information about you. Because the servers without sign-in do not know who you are, please include what helps us find the record, such as a WIA A11y result ID or a WIA360 session reference. We answer within 10 days. You may also contact the Personal Information Dispute Mediation Committee (www.kopico.go.kr, 1833-6972) or the KISA Privacy Center (privacy.kisa.or.kr, 118).
7. Children, security and changes
These servers are not directed at children under 14. The MCP servers are served over HTTPS only, and access to logs is limited to our administrators. If we change this policy, we will update this page and the date at the top.
