These Terms of Service (the “Terms”) govern your access to and use of Mianos, an online marketplace operated by Mianos Oy (“Mianos”, “we”, “us”) that connects buyers and sellers of advertising space, including physical billboards, vehicles and venues, as well as digital placements such as newsletters, podcasts and social-media channels. By creating an account, browsing listings or otherwise using the service you agree to these Terms. If you do not agree, do not use Mianos.
01.Acceptance and eligibility
You may use Mianos only if you are at least 16 years old and have the legal capacity to enter into a binding contract under the law of your country of residence. If you use Mianos on behalf of a company or other organisation, you represent that you are authorised to bind that entity to these Terms, and “you” refers to that entity as well as the individual using the service.
We may, at our discretion, require additional verification (for example, identity or tax documentation) before allowing certain features such as receiving payouts or publishing high-volume listings.
02.Account registration and security
To use most features you must create an account. You agree to provide accurate, current and complete information and to keep that information up to date. You are responsible for safeguarding your credentials and for all activity that occurs under your account. Notify us promptly at security@mianos.com if you suspect unauthorised access.
We may refuse, suspend or close accounts that contain false information, that are associated with fraud, abuse or other violations of these Terms, or where we are required to do so by law.
03.Mianos's role: a venue and escrow facilitator
Mianos is a marketplace and escrow facilitator. We are not a party to the underlying advertising transaction between buyer and seller, we do not own, sell or operate the advertising space listed by sellers, and we are not the publisher of any creative material supplied by buyers. The contract for the advertising service is concluded directly between buyer and seller.
Payments are processed by our payment provider, Stripe, and held in escrow by Stripe on behalf of the parties until release conditions are met (see section 5). We do not store full card data or hold customer funds on our own balance sheet.
Although we curate listings and may remove content that breaks our rules, we do not pre-screen every listing or message and we do not guarantee the quality, safety, legality, or commercial outcome of any transaction.
04.Listings, intellectual property and prohibited content
Sellers are responsible for their listings, including descriptions, photographs, location data, pricing, available impressions and any claims about audience or performance. Listings must accurately reflect the advertising space being offered and must not be misleading.
By posting a listing or any other content on Mianos you grant Mianos a worldwide, non-exclusive, royalty-free licence to host, display, reproduce and adapt that content for the purpose of operating, promoting and improving the service. You retain all ownership rights in your content. You must own or have the necessary rights to all content you upload.
The following content is not allowed on Mianos:
- Adult, sexually explicit or pornographic content;
- Hate speech or content inciting violence or discrimination on the basis of race, ethnicity, nationality, religion, gender, sexual orientation, disability or similar grounds;
- Content promoting illegal goods, services or activities, including unlicensed financial products, narcotics, weapons or counterfeit goods;
- Political advertising restricted under EU Regulation 2024/900 on the transparency and targeting of political advertising, unless the parties comply with all applicable disclosure and verification requirements;
- Content that infringes intellectual property, privacy or publicity rights of third parties;
- Malware, phishing links or other content that compromises the security of the service or its users.
We may remove or disable access to listings or other content that we reasonably believe violate these Terms, applicable law, or our published category guidelines.
05.Offers, bargaining and escrow
Buyers may submit offers on a listing or accept a published package price. Buyer and seller may negotiate price, dates and scope through the on-platform messaging system. Once both parties agree on the terms, the buyer pays through the platform; funds are captured into escrow by Stripe.
The seller then publishes the advertising and submits proof that the ad has gone live (such as a photograph, screenshot, or analytics export). After the buyer approves the proof, escrowed funds are released to the seller, less applicable fees. If the buyer neither approves nor disputes within the auto-release window disclosed at checkout (typically seven days from proof submission), the funds are released automatically.
All material communication and negotiation must happen on Mianos. Bypassing the platform to transact off-platform after a connection has been made through Mianos is a material breach of these Terms (see section 11).
06.Fees and payouts
Mianos charges a platform commission on completed transactions. The applicable buyer service fee and seller commission are disclosed at checkout and on each listing's fee breakdown before the order is confirmed. Stripe processing fees are charged in addition where applicable and are disclosed in the same breakdown.
Payouts to sellers are made through Stripe Connect on the schedule selected in the seller's Stripe account, subject to Stripe's payout terms and any holds Stripe may apply for risk or compliance reasons. Sellers are responsible for collecting and remitting any taxes due on their sales, including VAT where applicable.
07.Buyer obligations
As a buyer you agree to:
- Supply final creative material in the agreed format and within the agreed deadline;
- Ensure that your creative complies with these Terms, the seller’s reasonable specifications, and all applicable laws (including advertising, consumer protection, and intellectual property law);
- Review and approve or reject the seller’s proof of ad-live promptly and in good faith;
- Not use Mianos to launder funds, finance illegal activity, or evade sanctions.
08.Seller obligations
As a seller you agree to:
- Maintain accurate and up-to-date listings, including pricing, availability and audience information;
- Deliver the advertising service as described, on the agreed dates and at the agreed location or channel;
- Submit truthful proof of ad-live promptly after publication;
- Hold any licences, permits, landlord consents or operator agreements required to lawfully sell the advertising space;
- Handle disputes in good faith, communicate constructively with the buyer, and respond to requests from Mianos within the timeframes we set.
09.Disputes, refunds and chargebacks
Either party may open a dispute before escrow funds are released, for example because the proof of ad-live is missing, the ad was not published as described, or the creative does not comply with the agreed brief. Mianos administrators will review the evidence from both sides and may release, partially refund or fully refund the escrowed amount.
Mianos's decisions on disputes are made in good faith and are final as between the parties for purposes of escrow release, but they do not limit any statutory rights you may have, in particular consumer rights granted by mandatory provisions of EU and Finnish consumer law.
If a buyer initiates a chargeback with their card issuer, we may suspend the related order and any onward payouts pending resolution. Where a chargeback is upheld, we may recover the disputed amount plus reasonable costs from the seller.
10.Reviews
Reviews must be honest, based on a real transaction completed through Mianos, and free of personal attacks, discriminatory language and confidential information. You may not offer incentives in exchange for positive reviews, post reviews of your own listings, or coordinate review manipulation. We may remove reviews that violate these rules.
11.Prohibited activities
You agree not to:
- Use Mianos for any unlawful, fraudulent or deceptive purpose;
- Circumvent the platform after a connection has been made on Mianos in order to avoid fees or platform protections;
- Scrape, crawl, mass-download or otherwise extract data from Mianos except as permitted by our public API or robots.txt;
- Reverse-engineer, decompile or attempt to derive the source code of the service, except where such restriction is prohibited by law;
- Manipulate listings, search rankings, reviews or pricing through coordinated inauthentic behaviour or fake accounts;
- Interfere with or disrupt the integrity, security or performance of the service.
12.Suspension and termination
We may suspend or terminate your access to Mianos, with or without notice, if we reasonably believe that you have breached these Terms, that your account presents a security or compliance risk, or where we are required to do so by law. Where the breach is non-material and remediable, we will normally give you a chance to cure it before suspension.
You may close your account at any time from your account settings. Closure does not release you from obligations that arose before closure, including pending orders, fees and indemnities.
If your account is suspended you may appeal by emailing appeals@mianos.com with the facts you wish us to reconsider. We aim to respond to appeals within fourteen (14) calendar days.
13.Disclaimers
Except as expressly required by mandatory law, the service is provided “as is” and “as available”. Mianos does not warrant that listings will generate a particular number of views, conversions or sales, that the service will be uninterrupted or error-free, or that any user will perform their obligations under a transaction.
Statutory consumer rights granted under EU and Finnish law to consumers (as opposed to traders) are not affected by this section.
14.Limitation of liability
To the maximum extent permitted by applicable law, Mianos's aggregate liability to you arising out of or relating to these Terms or the service is limited to the total amount of fees you have paid through the platform during the twelve (12) months immediately preceding the event giving rise to the claim. Mianos is not liable for indirect or consequential losses, lost profits, lost revenue, lost data or loss of goodwill, even if advised of the possibility of such loss.
Nothing in these Terms limits liability for fraud, gross negligence, or any other liability that cannot be limited under applicable law (including, for consumers, the statutory rights under EU and Finnish consumer law).
15.Indemnification
You agree to indemnify and hold Mianos and its officers, employees and contractors harmless from any third-party claims, damages, liabilities, costs and reasonable attorney's fees arising out of (i) your breach of these Terms, (ii) content you upload to Mianos, (iii) advertising you publish or commission through Mianos, or (iv) your violation of any law or third-party right. This section does not apply to consumers to the extent it would conflict with mandatory consumer law.
16.Governing law and jurisdiction
These Terms are governed by the laws of Finland, without regard to its conflict-of-law rules. The courts of Helsinki, Finland (Helsingin käräjäoikeus / Helsinki District Court) have exclusive jurisdiction over any dispute arising from these Terms or the service, except that consumers may also bring proceedings in the courts of their place of residence in the European Union as required by mandatory EU consumer law. Consumers may also use the European Commission's online dispute resolution platform at https://ec.europa.eu/consumers/odr.
17.Changes to these Terms
We may update these Terms from time to time. If we make material changes we will give at least thirty (30) days' notice by email or through the service before the changes take effect. Your continued use of Mianos after the effective date constitutes acceptance of the updated Terms. If you do not accept the changes, you must stop using Mianos and may close your account.
