PlaKat is a crowdsourced city poster wall: contributors upload photographs of street posters, event details are extracted, and posters are published to a public wall. It is a prototype provided “as is” and “as available”, without warranties of any kind. It may change, break, lose data, or be discontinued at any time.

Browsing the wall requires no account. To upload posters you sign in with an email and password, or optionally with Google or GitHub. You are responsible for the activity under your account and for keeping your credentials secure. You must be old enough to enter a binding agreement in your jurisdiction.

When you upload a poster, you affirm that you personally photographed that poster in a public place, and that you are not uploading someone else's photograph.

You grant PlaKat a non-exclusive, worldwide, royalty-free license to store, reproduce, and display your photograph and the extracted event details on the wall and its related surfaces, for the purpose of operating the service. You keep ownership of your photograph.

The artwork depicted in a poster remains the property of its rights holders. PlaKat displays poster photographs to document the fact of a public posting — not to republish or commercialize the underlying artwork.

If you hold rights to artwork shown in a poster, or your personal data appears in an image, you can ask us to remove it. Email oleksii.malikov@gmail.com with the poster URL and enough information to identify the content and your basis for the request. We honor legitimate removal requests promptly.

You must not upload or post:

• —content that is unlawful, or that infringes anyone's rights;
• —hateful, harassing, or violent content;
• —private personal data about others without a lawful basis;
• —spam, advertising unrelated to a real posting, or automated bulk submissions.

The operator may remove any content, refuse or reverse any publication, and suspend accounts at its discretion, particularly where content appears to breach these terms. Uploads may be rate-limited to protect the service and deter abuse. Duplicate submissions of the same event may be detected and merged or refused.

Event details are extracted by software from photographs and may be wrong, incomplete, or out of date. Verify details with the organizer before relying on them. To the fullest extent permitted by law, PlaKat and its operator are not liable for any loss arising from use of the service or reliance on its content.

These terms may change as the prototype develops. Material changes will be reflected on this page. Continued use after a change means you accept the updated terms.

These terms are intended to be governed by the laws of Switzerland, with the courts of Zürich as the place of jurisdiction, so far as mandatory consumer-protection law permits. (Placeholder — confirm the governing law and venue with legal counsel before launch.)
