Privacy policy

Haijin collects only what is necessary and sells no data. This page explains what is kept, why, for how long, and how to exercise your rights.

Data controller

David, 190 route de chez mermier 74370 Villaz. Contact for any question about personal data, david@haijin.io.

Data collected

  • Account. Email address, pen name, and if you provide them, display name, short bio and place. The date you accepted the terms and the date of your last sign-in.
  • Content. Your haiku, their language, form, season and answers.
  • Interactions. Resonances, follows, blocked accounts, and the reports you make.
  • Technical data. The IP address linked to the publication of a haiku and to sign-in, kept encrypted for one year in line with the legal obligation of content hosts. Irreversible fingerprints of IP addresses are used to limit abuse and disappear within an hour, or after twelve months for the log of sensitive actions.

Purposes and legal bases

  • Creating and operating your account, publishing your poems, displaying your profile. Legal basis, performance of the contract formed by the terms of use.
  • Keeping the service secure, preventing abuse and moderating content. Legal basis, the publisher's legitimate interest.
  • Meeting the legal obligations that apply to content hosts. Legal basis, legal obligation.

No data is used for advertising or profiling. No automated decision produces effects on you.

Cookies and trackers

Haijin sets a single cookie, named “haijin”. It keeps your session and protects forms against fraudulent submissions. It is strictly necessary to the service and exempt from consent. It lasts thirty days at most. The site uses no audience statistics, no advertising, no embedded social network and no typeface loaded from a third-party service.

Retention periods

  • Account and content, until the account is deleted, which immediately erases your poems, resonances and connections.
  • Sign-in links, twenty minutes, then purged.
  • Encrypted IP addresses linked to publications and sign-ins, twelve months.
  • Log of sensitive actions, twelve months.
  • Host backup copies, rotated over a few weeks.

Recipients and hosting

Your data is hosted by Infomaniak Network SA, Rue Eugène-Marziano 25, 1227 Genève, Suisse, in Switzerland. The European Commission recognises Switzerland as providing an adequate level of protection. Sign-in emails pass through the mail service configured by the publisher. Your poems and profile are public, readable without an account and indexable by search engines. Your email address is never displayed.

Your rights

You have rights of access, rectification, erasure, restriction, objection and portability. From your settings you can edit your profile, download all your data as JSON and delete your account. For any other request, write to david@haijin.io. You will receive an answer within one month. If you believe your rights are not respected, you may complain to the CNIL, 3 place de Fontenoy, 75007 Paris, www.cnil.fr.

Minors

The service is intended for people aged 15 or older. An account whose holder is younger is closed as soon as the publisher becomes aware of it.

Security

Exchanges are encrypted with HTTPS. Sign-in is passwordless, with a short-lived single-use link. Technical secrets are encrypted in the database, access to the administration is protected by a strong password and two-factor authentication, and sensitive actions are logged.

Links and private messages

You may offer a link to another member, who is free to accept or decline it. Once a link is accepted, you can write to each other privately. These messages are stored encrypted on the server and the team does not read them. If one of the two participants reports a message, that message is then passed to the moderation team for review. Ending a link deletes the conversation for both people, and deleting an account deletes all its exchanges. An email without any content may tell you a message is waiting, at most once a day, and it can be turned off from the messages page. Legal basis, performance of the service you request. Retention, until the link is ended or the account is deleted.
