Privacy Policy
jp-titp-actions · Operator: MK Career Planning · Last updated: 2026-11-01
1. What we handle
- Payer wallet address and transaction hash of each paid call (x402, USDC), with the tool name, price, network and time.
- Results of paid calls (the response body), so that you can fetch them again with
get_receipt if the response was lost after payment. The stored result includes the inputs you sent (for example the dates and places of an itinerary).
- Retry check value: while a paid result is kept, we also keep a keyed one-way value of the tool name and the arguments (HMAC-SHA256 with a secret key), used only to recognise a retry with the same payment. It cannot be turned back into the inputs without the key, and it is deleted together with the result. Calls that are not settled (paused, refused or failed) keep no such value. Records made before 2026-11-01 may hold an unkeyed SHA-256 hash of the arguments instead, which is deleted on the same schedule.
- Free tool usage: daily counts per tool and channel, and a daily estimate of distinct callers computed from a one-way hash of the first three parts of the IP address with a key that changes every day. We do not store free tool inputs in our database.
- Request logs: request logging (Cloudflare Workers Logs) is turned off for this service, so the names, places or other inputs you send are not kept in a request log.
- MCP responses: this service does not write MCP responses to storage; each response is sent directly over the connection.
- IP addresses: we do not store IP addresses in our own database. Cloudflare, which hosts this service, processes IP addresses and request metadata to deliver the service and may keep them in its logs, under Cloudflare's own policy. To enforce per-client rate limits on free calls, we pass a one-way hash of your IP address and the first 64 characters of your User-Agent to Cloudflare's rate-limiting counters, which only count requests over about a minute; we do not store either.
- Names in the published administrative actions under the Technical Intern Training Act: this service stores the actions published by the Immigration Services Agency of Japan (type of action, organization name as published, prefecture and municipality of the published address, permit and plan certification numbers, reason as published and date of the action) solely to relay them and to record changes between file versions. It does not store representative names or street addresses. Some implementing organizations are sole proprietors; their names are returned only as published and are not combined with other information. When an action no longer appears in the published files, we stop returning it and delete its content (name, address, numbers, reason and dates) and its earlier change entries; only a fingerprint of the deleted row and the times are kept for audit. Requests about this data go to the support contact below. Search terms you send are not stored.
We do not ask for names, email addresses or accounts to use the API.
2. Why
- To process payments, prevent double charges (idempotency) and let you re-fetch a paid result.
- To keep accounting records and to enforce daily limits.
- To measure aggregate usage. Our own monitoring payments are excluded from customer figures.
3. Third parties
- Cloudflare (hosting, storage, logs).
- Payment facilitator that verifies and settles x402 payments: Coinbase Developer Platform (api.cdp.coinbase.com), or PayAI (facilitator.payai.network) or Dexter (x402.dexter.cash) as a fallback. When a paid HTTP endpoint is settled through Coinbase, Coinbase may list that endpoint (not you) in its public x402 Bazaar catalog. The facilitator receives the signed payment, which includes your wallet address.
- Public blockchain: payments settle on Base. Wallet addresses, amounts and transaction hashes on a public blockchain are public and permanent; neither we nor anyone else can delete them.
We do not sell personal data and do not use it for advertising.
4. Retention
- Results of paid calls and their retry check values: 30 days after settlement, then deleted together (
get_receipt then returns RECEIPT_NOT_FOUND).
- Payment records (wallet address, transaction hash, amount, tool, time): 7 years for accounting, then deleted.
- Free tool daily counts: kept as aggregate statistics.
- Deleted data: after we delete data (at the end of a retention period or on request), it can remain recoverable through our database provider's point-in-time recovery (Cloudflare D1 Time Travel) for up to 30 days, after which it is gone.
- Request logs: turned off for this service. Other Cloudflare logs: according to Cloudflare's retention settings.
5. Requests and contact
To ask about or request deletion of data linked to your wallet address, contact: mk.career.planning@gmail.com
Please send the wallet address and, if possible, the receipt_id or transaction hash. We can delete stored results; payment records required for accounting are kept for the period above, and data on the blockchain cannot be deleted.
6. Disclaimer
This service relays and restructures the administrative actions under the Technical Intern Training Act published by the Immigration Services Agency of Japan (ISA). It is not an official list or service of ISA or the Government of Japan. It is not legal advice, not an assessment of any organization, and not an application service. Each action is shown as published on the date given; it does not mean that the organization currently has problems. Actions that ISA no longer publishes are not returned. Always confirm on the official ISA page. See the Terms of Service.
7. Changes
We will update this page and its date when this policy changes. See also Support and the Terms of Service.
日本語の要旨
- 運営者：MK Career Planning
- 扱う情報：有料の呼び出しの支払い元ウォレットアドレス・取引ハッシュ・金額・時刻、有料の結果（receipt で再取得するため。送られた入力を含みます。例：旅程の日付と場所）、有料の結果を残すあいだは、同じ支払いでの再試行を見分けるためだけに、道具の名前と入力から秘密の鍵で作った一方向の値（HMAC-SHA256。鍵がなければ入力に戻せません）も残し、結果と一緒に消します（精算しなかった呼び出しには残しません。2026-11-01より前の記録には鍵なしの SHA-256 が入っていることがあり、同じ期間で消します）、無料ツールは道具・経路ごとの1日の回数と、IP アドレスの上位3つの区切りを日替わりの鍵でハッシュした1日の利用者数の推定（無料ツールの入力は当方のデータベースに保存しません）。このサービスは呼び出しの記録（Cloudflare の Workers Logs）を止めており、送られた名前・場所などの入力は呼び出しの記録に残りません。MCP の応答は保存に書かず、そのまま接続で返します。IP アドレスは当方のデータベースには保存しません（Cloudflare のログの範囲で Cloudflare が扱います）。無料の呼び出しの上限を数えるため、IP アドレスと User-Agent の先頭 64 文字をまとめた一方向のハッシュを Cloudflare の回数の計数（1分程度）に渡しますが、どちらも保存はしません。
- 公表された行政処分等に掲載された名称（技能実習）：このサービスは、出入国在留管理庁が公表する技能実習法に基づく行政処分等（処分の種類・公表された名称・所在地の都道府県と市区町村・許可番号と技能実習計画の認定番号・公表された処分理由・処分の日付）を、中継と版ごとの変化の記録の目的に限って保存します。代表者名・番地は保存しません。実習実施者には個人事業主もあり、その名称は公表どおりに返すだけで、ほかの情報と組み合わせません。公表のファイルに載らなくなった処分は返さなくなり、その中身（名称・所在地・番号・処分理由・日付）と過去の変化の記録を消します。監査のために、消した行の指紋と時刻だけを残します。この情報に関するご依頼は下記の問い合わせ先へお寄せください。送られた検索の語は保存しません。
- 目的：決済・二重課金の防止・結果の再取得・会計記録・1日の上限・利用の集計。
- 第三者：Cloudflare（配信・保存）、集金係（Coinbase Developer Platform、予備に PayAI・Dexter。Coinbase で精算した有料の HTTP の口は、Coinbase の公開の一覧に載ることがあります。載るのは口であって、利用者ではありません）、ブロックチェーン（Base 上の取引は公開され、消せません）。
- 保存期間：有料の結果と再試行の照合用の値は精算から30日で一緒に消し、支払いの記録（アドレス・取引ハッシュ・金額・道具・時刻）は7年。消したデータ（保存期間の終わり・削除の依頼）も、データベースの時点復元（Cloudflare D1 の Time Travel）で最長30日は戻せる状態で残り、その後はなくなります。
- 削除依頼・問い合わせ：mk.career.planning@gmail.com（ウォレットアドレスと receipt_id または取引ハッシュを添えてください）。
- 免責：出入国在留管理庁が公表する技能実習法に基づく行政処分等の中継・整形であり、入管庁・日本国政府の公式の一覧・サービスではありません。法的助言・団体や事業者の評価・申請の代行ではありません。処分は示した日付に公表されたとおりに示しており、その団体・事業者に現在問題があることを意味するものではありません。入管庁が公表しなくなった処分は返しません。必ず入管庁の公式のページで確かめてください。利用規約もご覧ください。
