Terms of use

1. Purpose

These terms govern the use of Haijin (https://haijin.io), a network for sharing short poems. By creating an account or using the service, you accept them.

2. Access and account

The service is reserved for people aged 15 or older. You sign in with a single-use link sent to your email address. You choose a public pen name. You agree to provide a valid email address, to open only one account and to keep access to your mailbox safe. Access to the account is strictly personal.

3. Publishing

You publish only poems of your own composition, within the technical limits of the service, which are 17 syllables and three lines at most per poem. Detailed rules appear in the haiku charter, which forms part of these terms. You are responsible for what you publish.

4. Licence granted

Your poems remain yours. By publishing them, you grant Haijin a non-exclusive, worldwide, royalty-free licence to host, display, reproduce and distribute them on the site and in its RSS feeds for as long as they stay published. This licence ends when you remove the poem or delete your account, allowing for the technical time needed to purge copies and backups.

5. Moderation and sanctions

Any content can be reported. The publisher may hide content, or suspend or close an account that breaches the law, the charter or these terms. The author of hidden content is told the reason for the decision and can contest it by writing to david@haijin.io.

6. Liability

Haijin hosts content published by its members. The publisher acts promptly to remove manifestly unlawful content as soon as it becomes aware of it, as required by French law on trust in the digital economy. The service is provided as is. The publisher strives to keep it available without being able to guarantee it, and may interrupt it for maintenance.

7. Personal data

The processing of your data is described in the privacy policy.

8. Account deletion

You can delete your account at any time from the settings. Deletion erases your poems, resonances and connections.

9. Changes to the terms

These terms may change. Significant changes are announced on the site. Using the service after publication means you accept them.

10. Applicable law

These terms are governed by French law. In case of dispute, and failing an amicable settlement, French courts have jurisdiction, subject to mandatory rules protecting consumers.
