Terms of Service

These Terms apply to all relations between a user and the AdMosaic operator identified in the Commercial Transaction Disclosures. The service is available only to corporations, organisations, and sole proprietors acting for business or professional purposes.

Users must be at least 18 years old and represent that they have authority to bind the organisation for which they act.

AdMosaic enables users to reserve and purchase digital advertising spaces and display approved creative for a defined term. The checkout or applicable individual terms specify the space, size, duration, display method, and included features.

The operator may make reasonable technical or presentation adjustments for security, legal compliance, or quality, but will not unfairly reduce the essential value of a purchased placement.

Users must provide accurate, current information, safeguard credentials, and must not lend, transfer, share, or sell accounts. Users must promptly report suspected unauthorised access or disclosure.

The operator may invalidate sessions, require additional verification, or temporarily restrict access where reasonably necessary to protect the service or its users.

A temporary reservation holds a space only until its displayed expiry and does not guarantee purchase or publication. It expires automatically on timeout, failed payment, or cancellation.

A paid placement contract is formed when the user accepts the checkout terms, Stripe confirms payment, and AdMosaic records the completed payment. In the event of a material pricing error, duplicate sale, fraud, or serious system fault, the operator may cancel and issue a full refund with prompt notice.

Dynamic pricing may reflect position, size, term, availability, and recent delivery performance. The formula and adjustment thresholds are not published. The displayed price is fixed during the reservation window and for the purchased term after checkout.

The launch campaign provides 30% off the first purchase, capped at ¥3,000, through September 30, 2026 at 23:59 JST. It is limited to one redemption per business. Duplicate use through another account or other abusive use is excluded. The operator may use business information, payment-method identifiers, hashed IP data, and other reasonable signals to determine eligibility and may withhold or revoke a discount or investigate suspected duplicate or abusive use.

Charges are made in Japanese yen. Users bear card conversion charges, cross-border fees, withholding, VAT, GST, and other taxes arising in their jurisdiction unless the operator is legally required to collect them.

The user must submit a creative and HTTPS destination satisfying the stated format, file-size, and resolution requirements within 14 days after payment. The operator may review the creative, destination, claims, supporting evidence, and advertiser under the Ad Policy.

Rejected creatives may be corrected and resubmitted. The operator may issue a final rejection where legal, rights, evidence, or technical concerns remain unresolved. Review is not legal advice and does not guarantee the legality of an advertisement.

The purchased term begins when an approved advertisement is actually published, not on the payment date. Placement ends automatically at the end of the purchased term and does not renew automatically.

No extension or refund is provided for delay caused by the user's late submission, correction, or failure to respond. Individually agreed start dates prevail where applicable.

The operator does not guarantee impressions, clicks, CTR, enquiries, sales, search ranking, or any other outcome. Reports may contain technical estimates and may be corrected for bot filtering, deduplication, outages, or methodology changes.

Users must not present report data to third parties in a misleading way or conceal material measurement qualifications.

Users warrant that they possess all rights and permissions required for their creative, marks, logos, copy, destination, and third-party materials.

Users grant the operator a non-exclusive, worldwide, royalty-free licence to reproduce, transmit, display, resize, and convert submitted material as necessary for review, delivery, thumbnails, share cards, service promotion, records, and fraud prevention during the placement and reasonable retention periods. Ownership does not transfer.

Users must not violate law, these Terms, or the Ad Policy; provide false information; infringe rights; gain unauthorised access; probe vulnerabilities; distribute malware; impose abusive automated load; manipulate metrics; trade accounts; or evade sanctions or export controls.

Impersonation, material destination changes after review, and replacement of approved material with unapproved content are prohibited.

Where a violation or reasonable suspicion exists, the operator may hold review, suspend or remove a placement, disable a destination, preserve evidence, or restrict an account without prior notice. Where urgency permits, the operator will reasonably provide reasons and an opportunity to cure.

Users must provide licences, rights evidence, substantiation, and other reasonably requested documents within the specified period.

Reservations may be cancelled before payment. No refund is due for a change of mind after payment, failure to submit within 14 days, failure to complete review, or suspension caused by a breach of these Terms or the Ad Policy.

If compliant resubmissions are exhausted and publication remains impossible for reasons not caused by the user, undelivered service will be refunded. For a material operator-caused outage, the remedy is a reasonable pro-rata refund for the affected undelivered portion; no complimentary extension is provided.

The operator may temporarily interrupt the service for maintenance, security, legal or governmental requirements, network or cloud failures, disasters, or other reasonable necessity, with advance notice where practicable.

If a material change adversely affects a purchased contract, the operator will provide a reasonable alternative or refund the undelivered portion.

The operator does not warrant uninterrupted operation, third-party destination safety, advertising outcomes, or fitness for a particular purpose, except for liability that cannot be excluded by mandatory law.

Except for wilful misconduct, gross negligence, death or personal injury, or other liability that cannot legally be limited, liability is limited to direct and ordinary loss and in aggregate to the amount actually paid for the affected placement. The operator is not liable for lost profits, indirect, special, consequential, or data-loss damages, even if foreseeable.

A user must resolve at its own expense third-party claims arising from its advertisement, destination, legal violation, rights infringement, or breach and reimburse the operator for reasonable loss and cost, except to the extent caused by the operator.

The operator may amend these Terms for legal, service, or security reasons. Material changes will be notified on the site or by registered email before taking effect and will not be applied retroactively to a purchased contract to the user's detriment.

Invalid provisions are severed without affecting the remainder. Users may not assign the contract without written consent. The operator may assign it as part of a legitimate business succession.

These Terms and the service are governed by Japanese law, excluding conflict-of-law rules. The Tokyo District Court has exclusive jurisdiction at first instance, except where mandatory law requires otherwise.

Legal notices and enquiries must be sent to the contact listed in the Commercial Transaction Disclosures.
