Terms of Service

Using Cella

Public pages are free to read. Artist, gallery, city, institution, festival, and sponsor workspaces may be used professionally under a free-beta, paid, or assigned plan. Use only the accounts, records, and workspace permissions assigned to you.

By using Cella, you agree to these terms. If you use a workspace for an organization, you must be authorized to act for it.

Plans and payment

Build or claim an artist record, add evidence, make corrections, keep a record of the art you experience, and share public records for free during early access. Artist and gallery Pro tools are also included. Free during early access. No card required. Joining does not start a paid subscription or automatic charges.

Basic city participation is free during early access. Approved teams can review assigned records, submit corrections and add condition information within their granted permissions. Advanced city services are confirmed separately.

Future paid plans will be announced before launch. A paid plan starts only after you choose it and accept its price and billing terms. Early access does not start automatic charges. Early members will receive benefits when paid plans launch. We'll share the exact benefits and terms before that happens. Joining early access does not enroll you in a paid subscription.

Automated research has a limited allowance. Saved findings, manual evidence and corrections remain available when that allowance is reached. A research request does not authorize a charge.

A record can exist without a certificate. No charge is made merely for reading a record, creating a free personal account, or joining early access. Any future certificate fee will be shown before you choose to issue one.

Before a purchase, the applicable checkout or agreement must identify the seller, amount, billing period, taxes if any, renewal terms, cancellation process, and any refund terms. An assigned workspace requires approval. A request or free account does not grant that assignment.

The early-access page does not modify a separate existing subscription or signed agreement.

Accounts and acceptable use

You must be at least 13 to create a personal account. Children under 13 can take part in a teacher-led or host-led visit without personal accounts or submissions.

Provide accurate account information and protect your credentials. Do not impersonate an artist, gallery, contributor, or organization. Do not bypass access controls or submit evidence you know is false.

Do not scrape or resell the registry without written permission from Cella. Normal public browsing, linking to records, and permitted search-engine indexing are allowed. Do not disrupt the service or use it to infringe another person’s rights.

Your content and public history

You retain the rights you hold in content you submit. You must have permission to provide it. You grant Cella a non-exclusive license to store, display, and use that content as needed to operate the feature you submit it to, including the public registry when you submit a public contribution.

Submitted evidence is reviewed before acceptance. Cella may reject or remove material that is inaccurate, unlawful, infringing, or outside the record’s scope. Accepted history can remain part of a public record after account closure. See Privacy for personal-information removal requests.

A later report adds a new entry. It does not automatically rewrite earlier history. A public record is not a promise that an artwork is still present or accessible.

Copyright complaints

Send a rights complaint to legal@cella.art with the affected record and media URLs, identification of the copyrighted work, your contact information, your physical or electronic signature, a good-faith statement that the use is not authorized by the rights holder, its agent, or the law, and a statement of accuracy and authority under penalty of perjury.

Cella reviews complaints and can restrict or remove disputed media while preserving appropriate record history. Repeat infringing submissions can result in account restrictions or termination. Contact legal@cella.art to contest a removal. Do not submit false complaints. A contact address alone does not establish Copyright Office agent registration or safe-harbor qualification.

Graffiti and tagging

Cella records evidence of existing work. A record, account, alias, claim, or contribution does not grant permission to paint, enter property, or access rail infrastructure. Document only from places you may lawfully access. Do not submit access points, live train positions, routes, or schedules.

Evidence, visits, and certificates

A save is a bookmark, not ownership or proof of a visit. Visit checks may require location, a supported tag, or a beacon. Lens searches recorded images and does not prove a visit.

Open claim, Source-backed, Artist-confirmed, Cella verified, Certificate, and Uncertain or disputed describe different claims. One label does not automatically establish another. A certificate covers only the scope printed on it. It is not an automatic guarantee of ownership, value, authenticity, or every statement on a record.

These are Cella records, not total visitation or a measure of economic impact. Beacon activity does not count everyone who visited.

Availability and limits

Cella is provided as available. Tools marked beta can change or have limited functions. A public record can remain after removal of a work, but no perpetual hosting guarantee is made.

To the extent permitted by applicable law, Cella does not warrant that every record is complete, accurate, or continuously available. Nothing in these terms removes rights or remedies that the law does not allow to be excluded.

Privacy, changes, and contact

The Privacy Policy explains account information, photos, location, public records, and deletion requests. Changes to these terms will appear here with an updated effective date. Contact legal@cella.art with questions or a rights complaint. Include the affected record URL and a way to reply.
