Purposes of use
To reply to inquiries, arrange viewings, follow up on rental, purchase, management, or recruiting matters, and prepare individual quotations and contract documents.
To send subscribed content, service notices, and necessary transaction messages. Subscriptions can be stopped through the unsubscribe link in email or by contacting us.
To improve the website and service quality, and to handle legal, accounting, dispute, regulatory, or user-request matters.
To manage support records, avoid duplicate communication, follow up through customer groups or external-contact tools, and prevent spam, abuse, and security incidents.
Processors and third-party services
This website may use Vercel hosting, Resend email delivery, Plausible and/or Google Analytics, WeChat/WeCom, LINE, WhatsApp, and configured business webhooks.
We do not provide personal data to third parties except where permitted by law, with consent, for business outsourcing, joint use, or transaction performance.
Where overseas service providers are involved, we confirm the processing purpose, safeguards, and outsourcing conditions as needed.
Joint use within the group
To route rental, purchase, management, investment-consultation, or post-move-in support to the right desk, inquiry data, contact details, preferences, transaction progress, contract/management information, and support interaction records may be jointly used where necessary.
Joint users are limited to ELM HOLDING, ELM HOUSING, and ELM CAPITAL when they are involved in the matter. Provision to external partners or other third parties is handled with consent or a separate notice where required by law.
The party responsible for joint-use management is 株式会社 ELM HOUSING (〒170-0013 東京都豊島区東池袋1丁目18番1号 ハレザタワー20F, 代表取締役 軽部 洋子).
Overseas services and external channels
Hosting, email delivery, analytics, and support channels may involve service providers in Japan, the United States, the European Union, China, and other jurisdictions. Main providers include Vercel, Resend, Google, Plausible, Tencent/WeCom, LY Corporation/LINE, Meta/WhatsApp, and configured business-webhook recipients.
Vercel, Resend, analytics tools, and webhooks are mainly used as processors or business outsourcing services. Communications through WeChat/WeCom, LINE, or WhatsApp occur when the user chooses that channel.
When overseas services or external channels are used, we confirm processing purposes, retained data, safeguards, sub-processing, and external conditions as needed, and handle consent, records, or notices under applicable law.
Security safeguards
We apply access control, least-necessary use, encrypted transmission, logging and rate limits, HMAC and other API safeguards, employee/processor supervision, backups, and deletion or anonymization controls.
If an incident requiring report or notice occurs, we investigate, contain, record, report to regulators, and notify affected individuals as required by applicable law.
Requests, fees, and complaints for retained personal data
For notification of purpose of use, disclosure, disclosure of third-party provision records, correction, addition, deletion, suspension of use, erasure, suspension of third-party provision, or complaints, contact hello@elm-gr.com. We verify identity and respond by email or another lawful method where permitted.
Correction, deletion, suspension of use, and complaints are generally handled without a fee. If a fee within actual-cost scope is charged for purpose-of-use notification, disclosure, or third-party provision records, the amount and payment method will be explained in advance.
Retention, disclosure, and deletion
Inquiry and subscription records are retained for response, performance, accounting, dispute handling, and security-audit needs. When retention is no longer required, data is deleted or anonymized.
For disclosure, correction, addition, deletion, suspension of use, suspension of third-party provision, or complaints, contact hello@elm-gr.com. Identity verification may be required.
