Last updated: May 11, 2026

General information

Please read these Terms & Conditions (the “Agreement”, “Terms”) carefully before using the telegrin service (the “Service”), available at https://tg.grinfi.io (and any successor domain such as https://telegrin.io).

The Service is operated by Private limited company Grinfi OÜ (company number: 16546847, “we”, “us”, “our”), registered at Harju maakond, Tallinn, Kesklinna linnaosa, Vesivärava tn 50-201, 10152, Estonia.

By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

The Service

telegrin helps teams monitor public Telegram chats for relevant signals and to manage outreach to potential leads. The Service includes the web application, supporting APIs, AI-assisted classification and reply generation, and any related tools we make available from time to time.

Eligibility

You must be at least 18 years old and capable of entering into a binding contract to use the Service. If you use the Service on behalf of an organisation, you confirm that you have authority to bind that organisation to these Terms.

Account and security

You are responsible for safeguarding your credentials and for everything that happens under your account. Notify us promptly at [email protected] if you suspect unauthorised access. We may suspend or terminate accounts that show signs of compromise, fraud, or abuse.

Telegram accounts you connect

When you connect a Telegram account to the Service, you grant us limited access to operate that account on your behalf, strictly for the monitoring, classification, and messaging actions you configure. You confirm that:

You own the Telegram account or are explicitly authorised to use it for business purposes.
Your use of Telegram through the Service complies with Telegram’s Terms of Service, with all anti-spam and anti-abuse rules imposed by Telegram, and with applicable law.
You will not use the Service to evade Telegram rate limits, to bypass platform-level safety controls, or to operate accounts in a way that materially harms the Telegram platform or its users.

We may disable specific automations, individual accounts, or your entire workspace if we detect or reasonably suspect violations of this section.

Acceptable use

You agree not to use the Service to:

Send spam, unsolicited bulk messages, fraudulent offers, deceptive content, or material that infringes intellectual property rights.
Harass, threaten, defame, or otherwise harm any person.
Scrape, harvest, or otherwise collect data outside the scope of the monitoring you have legitimately configured.
Reverse-engineer, decompile, or circumvent technical protections of the Service.
Resell, sublicense, or otherwise commercially exploit the Service or its outputs without our prior written consent.
Use the Service in a way that violates applicable law (including consumer-protection, data-protection, anti-spam, and sanctions laws) in any jurisdiction you operate in or reach out to.

You are solely responsible for the legality of your outreach and for honouring opt-out and erasure requests from the people you contact.

Subscriptions, billing, and refunds

The Service is offered on paid subscription plans. Pricing, features, and limits are described on our pricing page or in your contract with us.
Fees are charged in advance through our payment processor (Stripe). By providing payment details, you authorise us and Stripe to charge the applicable fees.
Subscriptions renew automatically at the end of each billing period unless cancelled. You can cancel renewal at any time from within the Service or by emailing [email protected].
No refunds. Fees already paid are non-refundable. If you cancel, you keep access until the end of the current billing period, after which your subscription will not be renewed.
We may change pricing for future billing periods on reasonable advance notice. Continued use after the change takes effect constitutes acceptance of the new pricing.

Free trials, credits, and promotions

If we offer a free trial, promotional credits, or a discount, the offer is described at the time it is made and is subject to any additional terms shown then. We may modify or end promotional programs at any time. Promotional credits have no cash value and are not transferable.

Intellectual property

The Service and all original content, features, and functionality are owned by Grinfi OÜ and are protected by Estonian and international copyright, trademark, patent, trade-secret, and other intellectual-property laws.

We grant you a non-exclusive, non-transferable, revocable, limited licence to access and use the Service in accordance with these Terms. You retain ownership of the content you submit to the Service (your configurations, your outreach drafts, your lead data). You grant us a non-exclusive licence to use that content solely to operate, support, and improve the Service.

Data from third-party services

The Service ingests data from third-party services (in particular Telegram) at your direction. We have no control over, and assume no responsibility for, the availability, content, privacy practices, or terms of those third-party services. Your use of those services is governed by their own terms.

Links to other sites

The Service may contain links to third-party websites or services that are not owned or controlled by Grinfi OÜ. We are not responsible for the content, privacy policies, or practices of those third parties.

Service availability and changes

We work to keep the Service available, but we do not guarantee uninterrupted or error-free operation. We may modify, suspend, or discontinue parts of the Service at any time, with reasonable notice where practicable. Telegram may rate-limit, block, or change its platform in ways that affect the Service; we are not liable for resulting interruptions.

Warranty disclaimer

The Service is provided on an “as is” and “as available” basis, without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy of AI-generated outputs, or uninterrupted operation. Your use of the Service is at your sole risk.

Limitation of liability

To the maximum extent permitted by law, Grinfi OÜ and its directors, employees, partners, agents, suppliers, and affiliates will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, business opportunity, or goodwill, arising out of or in connection with your use of the Service, even if we have been advised of the possibility of such damages.

Our total aggregate liability for any claim arising out of or relating to these Terms or the Service is limited to the fees you paid to us in the 12 months preceding the event giving rise to the claim.

Some jurisdictions do not allow the exclusion or limitation of certain damages. In those jurisdictions, our liability is limited to the maximum extent permitted by law.

Indemnification

You agree to defend, indemnify, and hold harmless Grinfi OÜ and its affiliates from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or in connection with: (a) your use of the Service; (b) your violation of these Terms or applicable law; (c) your violation of any third party’s rights; or (d) the content or conduct of your outreach using the Service.

Termination

You may stop using the Service at any time and cancel your subscription as described above. We may suspend or terminate your access to the Service, with or without notice, if you violate these Terms, abuse the Service, fail to pay fees when due, or for other legitimate operational reasons. On termination, your right to use the Service ends immediately and we may delete your data as described in the Privacy Notice.

Governing law and disputes

These Terms are governed by the laws of Estonia, without regard to its conflict-of-laws rules. The courts of Tallinn, Estonia have exclusive jurisdiction over any dispute arising out of or in connection with these Terms, except where mandatory consumer-protection law grants you the right to bring an action in your country of residence.

Changes to these Terms

We may update these Terms from time to time. For material changes, we will give you reasonable advance notice by email or in-app message before the change takes effect. Continued use of the Service after the effective date constitutes acceptance of the updated Terms.
