Terms of Service

Last updated: October 2, 2026 · Effective: October 2, 2026 for new customers; November 1, 2026 for customers who accepted an earlier version

These Terms of Service (the "Terms") are a binding agreement between Sellinger AI OOD ("Sellinger", "we", "us" or "our") and the business or organization that creates an account or otherwise uses the Service ("Customer" or "you"). They govern your access to and use of the Sellinger platform at app.sellinger.ai, the website at sellinger.ai, our AI agents, APIs, connectors and related services (together, the "Service"). Please read them carefully, including the limitation of liability in Section 24.

1. Who We Are and How You Accept

The Service is provided by:

Sellinger AI OOD („Селинджър АИ“ ООД)

UIC (EIK) 208752836, registered in the Commercial Register and Register of Non-Profit Legal Entities kept by the Registry Agency of the Republic of Bulgaria

Registered office and address of management: Ring Tower business building No. 1, bl. 621, entr. 1, fl. 3, apt. 1, Mladost district, Sofia 1766, Bulgaria

Managed by Asen Asenov Levov and Viktorio Borisov Shopov, each acting separately

Email: hello@sellinger.ai · Phone: +359 896 699 009

You accept these Terms by ticking an acceptance box, or by clicking a sign up, sign in or purchase button next to a notice that refers to these Terms, or by signing an order form that refers to them. The contract is concluded electronically in English, and these Terms are available to you at any time at sellinger.ai/legal/terms, where you can save or print them. Our Privacy Policy and Data Processing Agreement ("DPA") form part of these Terms. If an order form signed by both parties conflicts with these Terms, the order form prevails for that order.

If you accept these Terms on behalf of an organization, you confirm that you have authority to bind it, and "you" means that organization.

2. Definitions

  • Agent means an AI agent you configure in the Service to research, write to, reply to, call or otherwise engage people on your behalf over a channel.
  • Connected Account means a third party account you connect to the Service, such as a LinkedIn, email, WhatsApp, Instagram, Facebook, telephone, calendar or CRM account.
  • Customer Data means all data you or your Users submit to the Service or that the Service collects for you, including lead lists, contacts, messages, conversation history, call audio and transcripts, personas, prompts and knowledge base content.
  • Output means content the Service generates for you, including messages, replies, summaries, research and scores.
  • Recipient means any person your Agents or Users contact, or attempt to contact, through the Service.
  • User means an individual you allow to use the Service under your account, including your employees, contractors and, for partners, your clients' personnel.
  • Workspace means a team or account space in the Service, including a white label portal.

3. Business Use Only

The Service is designed for businesses and professionals. By accepting these Terms you confirm that you act for purposes of your trade, business, craft or profession and not as a consumer, and that you are at least 18 years old. Consumer protection rules that apply only to consumers, including the statutory right of withdrawal for distance contracts, therefore do not apply. If mandatory law nevertheless treats you as a consumer, nothing in these Terms limits the rights that law gives you.

4. Accounts, Workspaces and Users

  • You must give accurate and complete registration and billing information and keep it up to date.
  • You are responsible for your Users, for keeping credentials and API keys confidential, and for all activity under your account, whether or not you authorized it, until you tell us of a compromise.
  • Tell us at once at hello@sellinger.ai if you suspect unauthorized access. Accounts are personal to a User and may not be shared.
  • If you sign in with Google, Microsoft or single sign on, your use of that provider is also governed by its terms. We may refuse, suspend or close a registration that contains false information or that we reasonably believe is linked to abuse.

5. The Service

Sellinger is an AI sales platform. Depending on your plan, it lets you run Agents across LinkedIn, email, WhatsApp, Instagram, Facebook, SMS, voice and live chat, find and enrich leads, detect intent signals, manage a CRM, book meetings, and connect AI assistants through our API and Model Context Protocol connector.

  • We may improve, change or remove features. If we remove a material feature you pay for, we will give you reasonable notice and, if the change materially reduces the Service, you may cancel and receive a pro rata refund of prepaid fees for the unused period.
  • Features marked beta, preview, test, sandbox or early access are provided as is, may change or stop at any time, and are excluded from any service commitment.
  • We aim for high availability but do not guarantee uninterrupted service. Maintenance, third party outages and changes made by Connected Account providers can affect the Service.

6. Trials and Credits

  • We may offer free trials, free credits or promotional plans. Their length, limits and eligibility are shown in the Service, and we may end or change them at any time. One trial per business.
  • If you add a payment method during a trial, your paid subscription starts automatically when the trial ends unless you cancel before then.
  • Credits (for example for lead reveals, enrichment, research or usage beyond a plan quota) are prepaid licences to use specific features, not money or e money. They have no cash value, cannot be transferred or exchanged, and are not refundable except where these Terms or the law say otherwise. Free or promotional credits expire as stated when granted. All unused credits lapse when your account is closed.

7. Fees, Billing and Taxes

  • Fees are set out on our pricing page, in the Service at checkout or in your order form. Plans may combine a base fee, per Agent or per seat fees, fees for additional Connected Accounts, usage quotas, overage fees and credit packs.
  • Automatic renewal. Subscriptions are billed in advance for each monthly or annual period and renew automatically for the same period until cancelled. You authorize us and our payment provider, Stripe, to charge your payment method for all recurring fees, usage and overage fees, and credit purchases.
  • Usage based fees and overages are charged in arrears or when a threshold is reached, as shown in the Service. Changes to the number of Agents, seats or Connected Accounts during a period may be prorated.
  • Prices exclude VAT and other taxes, which we add where the law requires. If you are a business in another EU member state with a valid VAT number, the reverse charge may apply. You are responsible for any withholding taxes and must gross up payments so we receive the full amount invoiced.
  • Invoices and receipts are issued electronically by Sellinger.
  • If a payment fails, we may retry the charge and, after giving you notice in the Service or by email, suspend paid features until the balance is paid. Overdue amounts between businesses carry statutory interest under Bulgarian law. You must raise any billing dispute within 60 days of the charge; disputing a valid charge with your bank instead of contacting us is a breach of these Terms.
  • Price changes. We may change prices with at least 30 days' notice by email or in the Service. The new price applies from your next renewal after the notice period. If you do not agree, you may cancel before it takes effect. Promotional discounts apply only for their stated term.

8. Cancellation and Refunds

  • You may cancel at any time in the Service or by writing to hello@sellinger.ai. Cancellation stops the next renewal; you keep access until the end of the period already paid for.
  • Fees already paid are non refundable, including for partial periods, unused seats, Agents, quotas or credits, except (a) as expressly stated in these Terms, (b) where we terminate for convenience or materially reduce the Service, in which case we refund prepaid fees for the unused period, or (c) where mandatory law requires a refund.

9. Your Responsibility for Outreach

The Service carries out outreach in your name and on your instructions. You decide whom to contact, through which channel, how often, and with what message or persona, and you are the sender of every message and call. You are therefore solely responsible for making sure your outreach is lawful. In particular, you must:

  • have a valid legal basis under the GDPR and other data protection laws for every Recipient's data you upload, collect, enrich or use, and give Recipients the information required by Article 14 GDPR where it applies;
  • comply with electronic marketing and anti spam laws that apply to you and to each Recipient, including the ePrivacy rules as implemented in EU member states (in Bulgaria, the Electronic Communications Act and the Electronic Commerce Act), the UK PECR, the US CAN-SPAM Act, the US Telephone Consumer Protection Act and state laws, and Canada's CASL, including any prior consent requirements for messages to individuals;
  • identify yourself as the sender, include a working way to opt out where the law requires it, honor opt outs and objections without delay, and keep Recipients who object on your suppression list;
  • obtain any consent required to record or transcribe calls, give the notices the law requires at the start of a call, and respect do not call registers and calling hour rules;
  • tell Recipients that they are communicating with an AI system, or that content or a voice is AI generated, wherever the law requires it, including under Article 50 of the EU Artificial Intelligence Act and US rules on artificial voice calls, and never claim to be human; you must not disable, remove or circumvent the AI disclosure features and defaults the Service provides;
  • not contact children, and not use special category data (such as health, religion, political opinions or sexual orientation) or criminal data to select or target Recipients;
  • keep sending volumes, daily limits and content within the rules of each Connected Account provider.

Our tools, defaults, limits and warnings are there to help you, not to replace your own legal judgment. We do not give legal advice and do not check whether your campaigns are lawful.

10. AI Agents and Output

  • Output is generated by machine learning models, including third party large language models. It may be inaccurate, incomplete, inappropriate or similar to output generated for others, and it can contain statements about people or companies that are wrong.
  • When you run Agents in an automated or autonomous mode, messages and calls may go out without human review. You choose that mode and you accept responsibility for what your Agents send. You should review personas, instructions, knowledge base content and sample Output before enabling automation, and monitor results.
  • Agents act within the instructions and permissions you give them. Commitments an Agent makes to a Recipient (for example on price, terms or meeting times) are made in your name; configure your Agents so they do not make commitments you are not prepared to keep.
  • As between you and us, you own the Output, subject to our rights in the Service and to third party rights in any material you supply. We do not use Customer Data or Output to train our own or third party general purpose AI models.
  • The Service does not make decisions that produce legal or similarly significant effects on individuals. Lead scores, intent signals and recommendations are aids for your sales team.

11. Connected Accounts and Third Party Platforms

  • You authorize us and our service providers to access your Connected Accounts and to send, receive, read and store messages, contacts and related data through them as needed to provide the Service. Some connections, including LinkedIn, run through our integration provider Unipile.
  • Your use of each platform remains subject to its own terms and policies, which you must follow. Sellinger is not affiliated with, endorsed by or sponsored by LinkedIn, Meta, WhatsApp, Instagram, Google, Microsoft or any other platform, and their names are used only to describe compatibility.
  • Platforms may limit, restrict, suspend or ban accounts, change their interfaces, or end access at any time. Automated activity on some platforms, including LinkedIn, may not be permitted by that platform's terms. You accept that risk. We are not liable for any action a platform takes against your account or for any loss of contacts, messages or reputation that results, and such events do not entitle you to a refund.
  • Integrations with third party services you choose, such as CRMs and calendars, are provided for your convenience. Those providers are not our subcontractors, and data you send to them is governed by your agreement with them.

12. Lead Data and Enrichment

  • The Service may supply contact and company data about people and businesses ("Lead Data"). Lead Data is supplied as is. We do not warrant that it is accurate, complete or current, or that any Recipient may lawfully be contacted.
  • You may use Lead Data only for your own business to business sales and marketing, in compliance with Section 9, during your subscription. You may not resell, sublicense, publish or bulk export Lead Data to build a competing database, or use it to make decisions about anyone's eligibility for employment, credit, insurance, housing or similar purposes.

13. Acceptable Use

You must not, and must not allow anyone to, use the Service to:

  • break any law or regulation, or infringe anyone's rights, including privacy, publicity and intellectual property rights;
  • send spam, chain messages, phishing or messages with false or misleading sender, header or subject information;
  • impersonate any person or organization, misrepresent your affiliation, or run fake, purchased or compromised accounts;
  • harass, threaten, defame, discriminate against or exploit anyone, or send hateful, sexually explicit, violent or otherwise offensive content;
  • promote illegal products or services, weapons, drugs, gambling where unlawful, pyramid schemes, payday or predatory lending, debt collection, or deceptive investment, crypto or get rich quick offers;
  • run political campaigning, election or lobbying outreach to individuals;
  • contact children or knowingly process data of children;
  • distribute malware, probe, scan or test the vulnerability of the Service, bypass security, rate limits or usage quotas, or access the Service by automated means other than our API and connectors;
  • copy, frame, reverse engineer, decompile or extract the source code, models, prompts or data of the Service, except to the extent mandatory law permits;
  • scrape, harvest or bulk export data from the Service, or use the Service or its Output to build or train a competing product or AI model;
  • place an unreasonable load on the Service or on any Connected Account provider; or
  • resell or provide the Service to third parties except under a written partner agreement with us.

We may investigate suspected violations, remove or block content, pause Agents or campaigns, and cooperate with authorities and platforms.

14. Customer Data

  • You own your Customer Data. You grant us a worldwide, non exclusive, royalty free licence to host, copy, process, transmit and display Customer Data only as needed to provide, secure, support and improve the Service, and to comply with law.
  • Your conversations, messages, lead lists, results and Connected Accounts belong to your Workspace. We access them only to run the Service for you (for example so your Agents can read replies and send messages), to give support you ask for, to review and improve your Agents' performance, to keep the Service secure, and to comply with the law.
  • Your conversations and Connected Accounts can only be used by your own Sellinger account. No other customer can see, access or use them, and we never sell them.
  • You are responsible for the accuracy, quality and legality of Customer Data and for how you obtained it. You confirm that Customer Data and its use in the Service do not infringe anyone's rights.
  • We may create and use aggregated or anonymized data derived from use of the Service (for example benchmarks of reply rates by channel) that does not identify you, your Users or any individual, and we own that data.
  • You are responsible for keeping your own copies of Customer Data that you need. The Service is not a backup or archiving service.

15. Data Protection

For personal data in Customer Data, you are the controller and we are your processor, and our Data Processing Agreement applies and forms part of these Terms. For account, billing, website and security data, we are an independent controller as described in our Privacy Policy. You must make your own privacy notice available to Recipients and must not instruct us to process personal data in breach of the law.

16. Partners, Agencies and White Label

If you use the Service to serve your own clients, including through a white label portal, you are responsible for your clients and their users as if they were your Users. You must bind them to terms at least as protective of Sellinger as these Terms, you remain liable for all fees, and you must not make any promise or warranty about the Service on our behalf. We have no contractual relationship with your clients unless we agree otherwise in writing.

17. API, Connectors and AI Assistants

You may access the Service through our API and our Model Context Protocol connector only with credentials we issue and within published limits. If you connect an AI assistant (such as Claude or ChatGPT), the assistant acts on your behalf with the access level you approve, its provider processes data under its own terms, and you are responsible for the actions it takes in your Workspace. We may change, rate limit or revoke API access to protect the Service.

18. Intellectual Property and Feedback

We and our licensors own the Service, including the software, models, prompts, workflows, designs, content, documentation and the Sellinger name and logos. Subject to these Terms and payment of fees, we grant you a limited, non exclusive, non transferable, revocable right during your subscription to use the Service for your internal business purposes. All other rights are reserved. If you give us suggestions or feedback, we may use them freely without obligation to you.

19. Confidentiality

Each party will keep confidential the non public information the other discloses that is marked or would reasonably be understood as confidential, use it only to perform these Terms, and protect it with at least reasonable care. This does not apply to information that is or becomes public through no fault of the recipient, was already known to it, is independently developed, or is lawfully received from a third party. A party may disclose confidential information when required by law, after notifying the other party where lawful. These obligations last for five years after termination, and for trade secrets for as long as they remain trade secrets.

20. Security

We maintain appropriate technical and organizational measures to protect the Service and Customer Data, as described in the DPA. You must use the security features we provide, protect your credentials and Connected Accounts, and promptly tell us of any security incident you become aware of that affects the Service.

21. Suspension

We may suspend all or part of the Service, or pause specific Agents, campaigns or Connected Accounts, if (a) you breach Sections 9, 13 or 17, (b) payment is overdue after notice, (c) we reasonably believe your use creates a security risk, legal exposure, harm to Recipients or risk to our relationship with a platform or provider, or (d) a law, court or authority requires it. Where reasonable, we will give notice first and limit the suspension to what is necessary. Fees remain payable during a suspension caused by you.

22. Term and Termination

  • These Terms apply from acceptance until all your subscriptions have ended and your account is closed.
  • Either party may terminate for material breach if the breach is not cured within 15 days after written notice. We may terminate immediately by notice for serious or repeated breaches of Sections 9 or 13, for fraud, or if you become insolvent. We may also terminate for convenience on 30 days' notice, with a pro rata refund of prepaid fees for the unused period.
  • On termination, your right to use the Service ends and all unpaid fees become due. For 30 days after termination you may export your Customer Data using the export features of the Service or by request. After that period we delete or irreversibly anonymize Customer Data in line with the DPA, except data we must keep by law and data we hold as an independent controller under our Privacy Policy.
  • Switching. If you want to move to another provider or to your own systems, tell us in writing. We will support the switch as required by the EU Data Act, including a transition period of up to 30 days and export of your exportable data in a structured, commonly used and machine readable format, and we will not charge switching fees that the law does not permit.
  • Sections that by their nature should survive, including Sections 7, 8, 12, 14, 18, 19 and 23 to 29, survive termination.

23. Warranties and Disclaimers

Each party warrants that it has the authority to enter into these Terms. We warrant that we will provide the Service with reasonable skill and care. Except as expressly stated in these Terms and to the fullest extent permitted by law, the Service, Output and Lead Data are provided "as is" and "as available", and we disclaim all other warranties and conditions, express or implied, including merchantability, fitness for a particular purpose, accuracy and non infringement. We do not promise any particular number of replies, meetings, sales or other business results, and we do not warrant that the Service will be uninterrupted or error free or that Connected Accounts will not be restricted.

24. Limitation of Liability

  • Neither party is liable for any loss of profits, revenue, business, contracts, opportunity, goodwill or anticipated savings, or for any indirect, consequential, special or punitive loss, even if foreseeable.
  • Each party's total liability arising out of or in connection with these Terms and the Service, in contract, tort or otherwise, is limited to the fees paid and payable by you to us for the Service in the 12 months before the event giving rise to the claim.
  • We are not liable for loss caused by your instructions, personas or campaigns, by Output you choose to send, by your breach of Sections 9 or 13, or by any act or omission of a Connected Account provider or other third party platform, other than our own sub-processors acting on our behalf.
  • These limits do not apply to your obligation to pay fees, to your obligations under Section 25, or to liability that cannot be limited or excluded by law, including liability for intent or gross negligence (Article 94 of the Bulgarian Obligations and Contracts Act) and for death or personal injury caused by negligence.

25. Indemnification

You will defend, indemnify and hold harmless Sellinger, its affiliates, managers, employees and contractors from and against all third party claims, regulatory investigations and fines, damages, losses, costs and reasonable legal fees arising from (a) your outreach, campaigns, Agents and Customer Data, including claims by Recipients, data protection authorities or platforms, (b) your breach of these Terms or of law, or (c) your clients and Users. We will notify you promptly of a claim, let you control its defense with counsel reasonably acceptable to us, and give reasonable cooperation at your cost. You may not settle a claim in a way that imposes an obligation or admission on us without our written consent.

26. Force Majeure

Neither party is liable for delay or failure to perform caused by events beyond its reasonable control, including natural disasters, war, terrorism, sanctions, epidemics, labor disputes, failures of public networks, power or hosting providers, cyberattacks not caused by its negligence, acts of authorities, and changes in third party platforms. This does not excuse payment obligations.

27. Changes to These Terms

We may update these Terms to reflect changes to the Service, our business or the law. For material changes we will give at least 30 days' notice by email to the account owner or in the Service, unless a change is required sooner by law or to address abuse or security, in which case it applies when posted. If you do not agree, you may cancel before the change takes effect and we will refund prepaid fees for the unused period. Continued use after the effective date means you accept the updated Terms. The "Last updated" date shows the current version.

28. Governing Law and Disputes

These Terms and any non contractual obligations arising from them are governed by the laws of the Republic of Bulgaria, excluding its conflict of laws rules and the UN Convention on Contracts for the International Sale of Goods. Before starting proceedings, the parties will try to resolve a dispute in good faith for 30 days after written notice. Disputes that are not resolved are subject to the exclusive jurisdiction of the competent courts in Sofia, Bulgaria. Either party may seek urgent interim relief in any competent court, and we may bring claims for unpaid fees in the courts where you are established.

29. General

  • Entire agreement. These Terms, the Privacy Policy, the DPA and any order form are the entire agreement on their subject and replace earlier versions and discussions. Terms in your purchase orders do not apply.
  • Assignment. You may not assign these Terms without our written consent. We may assign them to an affiliate or to a successor in a merger, acquisition or sale of assets, with notice to you.
  • Subcontracting. We may use subcontractors and service providers and remain responsible for them as set out in the DPA.
  • Notices. We give notices by email to the account owner or in the Service. You give notices to hello@sellinger.ai or by post to our registered office.
  • Severability and waiver. If a provision is held invalid, it is replaced by a valid provision closest to its intent and the rest remains in force. Failure to enforce a provision is not a waiver.
  • Relationship. The parties are independent contractors. Nothing creates a partnership, agency or employment relationship, and no third party has rights under these Terms.
  • Sanctions and export. You confirm that you and your Users are not subject to EU, UN, UK or US sanctions and will not use the Service in breach of sanctions or export control laws.
  • Publicity. We may list your company name and logo as a customer. You may opt out at any time by emailing us.
  • Language. These Terms are made in English. Any translation is for convenience, and the English version prevails.
