These Terms of Service (the “Terms”) govern your access to and use of Mianos (“Mianos”, “the Service”), an online marketplace operated by L&L Ventures Oy, a private limited company registered in Finland (“the Operator”, “we”, “us”). Register keeper / data controller: Leevi Latvaniemi. Mianos connects buyers and sellers of advertising space, including physical billboards, vehicles, windows, walls and venues, as well as digital placements such as newsletters, podcasts, social-media channels and websites. 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 eighteen (18) 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 and warrant 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, tax documentation, or written proof that you are entitled to sell the advertising space) before allowing certain features such as receiving payouts, publishing high-volume listings, or listing premium categories.
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 info@mianos.app 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.The Operator's role: an intermediary marketplace and escrow facilitator
Mianos is an online intermediary platform within the meaning of Articles 4 and 6 of Regulation (EU) 2022/2065 (the Digital Services Act). We provide the technical infrastructure that lets users publish listings, exchange messages, conclude bargains and arrange payment. We are not a party to any underlying advertising contract, we do not own, operate, lease, manage or control any advertising space listed on the Service, we are not the publisher, broadcaster or distributor of any creative material supplied by buyers, and we are not the agent of either the buyer or the seller. The contract for the advertising service is concluded directly between the buyer and the seller.
Payments and escrow. Payments are processed by our payment provider, Stripe (Stripe Payments Europe, Limited and its affiliates). Funds are captured into a Stripe-managed escrow account on behalf of the parties and held until the release conditions described in section 6 are met. The Operator does not store full card data and does not hold customer funds on its own balance sheet.
Although we curate the marketplace and may remove content that breaks our rules, we do not pre-screen every listing, message or piece of creative material, and we do not guarantee the accuracy, quality, safety, legality, suitability, brand-fit or commercial outcome of any transaction.
04.Listings: ownership of the advertising space and required permissions
You may only list advertising space that you own, lease, operate, or for which you have written authorisation from the rights-holder to sell advertising. Listing a third party’s property, surface, channel or audience without explicit written permission is a serious breach of these Terms and may also constitute fraud, trespass, unauthorised commercial use, or infringement of intellectual property, personality or contractual rights under Finnish and EU law.
Sellers are solely responsible for their listings, including descriptions, photographs, location data, pricing, available impressions and any claims about audience, reach 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 the Operator a worldwide, non-exclusive, royalty-free, sublicensable licence to host, display, reproduce, adapt (including for thumbnails, search previews and translations) and distribute that content for the purpose of operating, promoting and improving the Service. You retain all ownership rights in your content. You represent and warrant that you own or have secured the necessary rights, permissions and consents 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, personality or publicity rights of third parties;
- Malware, phishing links, automated bots, or other content that compromises the security or integrity 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.Brand safety, suitability and reputational risk
The Operator is not responsible for evaluating brand-fit, contextual suitability, audience demographics, neighbourhood reputation, or any reputational impact a campaign may have on a buyer’s brand or a seller’s venue. Buyers are solely responsible for vetting each listing, the seller, the surrounding context (physical neighbours, adjacent content on a digital channel, audience sensitivities) and any reputational consequences before placing an order. Sellers are solely responsible for vetting buyer creative for compatibility with the seller’s premises, audience, brand, contractual landlord obligations and applicable local law before publishing the ad. The Operator does not curate creative for brand-safety, ideological alignment, taste, or reputational risk and makes no representation as to either party’s reputation, solvency or trustworthiness.
06.Offers, bargaining, escrow and proof of placement
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, install receipt, 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 (7) days from proof submission), the funds are released automatically. The Operator is the technical operator of this escrow flow and is not itself a party to the advertising transaction.
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 14).
07.Fees and payouts
The Operator 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 solely responsible for collecting, declaring and remitting any taxes due on their sales, including Finnish VAT, income tax and any equivalent foreign tax (see section 9 for individual sellers).
08.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, marketing, tobacco, alcohol, gambling, financial-services, and intellectual-property law in every jurisdiction in which the ad will be visible);
- Hold all rights, licences and consents required for the creative material, including for any persons, brands, music, photographs or trademarks featured;
- Vet the seller, the listed venue or channel, and any contextual or reputational risk before paying — once funds are captured into escrow you accept those risks;
- 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, evade sanctions, or impersonate a third party.
09.Seller obligations (including individual / non-business sellers)
As a seller you agree to:
- Maintain accurate and up-to-date listings, including pricing, availability, location and audience information;
- Hold any and all licences, permits, landlord consents, tenancy agreements, building-management approvals, vehicle owner consents, channel operator agreements or other third-party authorisations required to lawfully sell the advertising space — and supply written evidence of those rights to the Operator on request;
- Deliver the advertising service as described, on the agreed dates and at the agreed location or channel;
- Vet buyer creative against your own venue, audience, contractual obligations and applicable local law before publishing — once you publish you assume responsibility for the publication on your premises or channel;
- Take and keep adequate insurance for damage that may arise to your own surfaces, equipment, premises or vehicles in connection with the publication of an ad (the Operator is not liable for any such damage — see section 12);
- Submit truthful proof of ad-live promptly after publication;
- Handle disputes in good faith, communicate constructively with the buyer, and respond to requests from the Operator within the timeframes we set.
Individual (non-business) sellers in Finland are reminded that income from selling advertising space is taxable income and must be declared to the Finnish Tax Administration (Verohallinto). The Operator may be obliged under Council Directive (EU) 2021/514 (DAC7) to collect and report identifying information and total consideration paid to sellers on the platform to the tax authorities of the seller’s residence each year. Individual sellers are also responsible for assessing whether their activity requires registration as a business (e.g. trade-name registration, VAT registration once turnover exceeds the small-business threshold), for arranging public-liability and property insurance covering damage to their own premises, and for complying with any housing-cooperative, employer, landlord or homeowner-association rules applicable to their property.
10.Damage to surfaces, premises and equipment
The Operator is not responsible for any physical damage caused to a surface, premises, vehicle, equipment, fitting, paintwork, glass, façade, wall, screen or any other property in connection with the installation, presence, removal or after-effect of an advertisement listed on the Service. Sellers warrant that the surfaces and equipment they list are suitable for the advertising they accept and that they hold any insurance, landlord consent, building permit or housing-cooperative approval required for the installation. Buyers warrant that their installation methods, adhesives, mounting hardware, removal procedures and any subcontractors they engage will not damage the seller’s property and that they hold appropriate liability insurance. Any claim for damage lies exclusively between the buyer and the seller (or their respective contractors and insurers).
11.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. Operator administrators will review the evidence from both sides and may release, partially refund or fully refund the escrowed amount.
Operator 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.
12.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.
13.Disclaimers — please read carefully
To the maximum extent permitted by applicable law, the Service is provided “as is” and “as available”. The Operator does not warrant or accept responsibility for, and expressly disclaims liability for, any of the following:
- The accuracy, completeness, legality, suitability or quality of any listing, message, creative material, audience claim, viewership figure, or proof of placement;
- Whether a seller actually owns or is otherwise entitled to sell the advertising space they list;
- Whether a buyer holds the rights to the creative they supply or has cleared all third-party permissions, releases, music licences, model releases, or trademarks;
- The performance, reach, conversion rate, revenue, or any other commercial outcome of an advertising campaign;
- Damage to surfaces, premises, vehicles, equipment or any other property in connection with the installation, presence, removal or after-effect of an advertisement (see section 10);
- Any reputational, brand-safety, brand-fit, public-relations, social-media, press or boycott consequence flowing from a campaign published on Mianos;
- Any tax, customs, regulatory, advertising-standards, planning-permission or licensing consequence of a transaction concluded through the platform;
- Acts or omissions of any user, including failure to deliver an ad, failure to pay, fraud, defamation, harassment, or breach of contract by a counter-party;
- Outages, downtime, data loss, security incidents, third-party API failures (including Stripe, MapTiler, Supabase, Resend) or force-majeure events;
- Any direct or indirect commercial harm caused by content moderation decisions taken in good faith.
Statutory consumer rights granted under EU and Finnish law to consumers (as opposed to traders) are not affected by this section.
14.Prohibited activities
You agree not to:
- Use Mianos for any unlawful, fraudulent or deceptive purpose;
- List advertising space you do not own or are not authorised to sell (see section 4);
- 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.
15.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 info@mianos.app with the facts you wish us to reconsider. We aim to respond to appeals within fourteen (14) calendar days. EU users also have the right to bring out-of-court dispute settlement to a certified body under Article 21 of the Digital Services Act.
16.Limitation of liability
To the maximum extent permitted by applicable law, the Operator’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. The Operator is not liable for indirect or consequential losses, lost profits, lost revenue, lost data, loss of goodwill, reputational harm, or harm to brand, 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).
17.Indemnification
You agree to indemnify and hold the Operator 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, (iv) damage to property in connection with the installation, presence or removal of an advertisement listed on the Service, or (v) 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.
18.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.
19.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.
