Terms of Service

1. The service

Antenna is a self-serve operations platform for Telegram channels and groups, operated by MARKETRONIX LTD, registered in England and Wales under company number 17331464, whose registered address is Dept 6916, 196 High Road, Wood Green, London, N22 8HH, United Kingdom ("Antenna", "we"), which operates the website at antenna.builders.

It schedules and publishes posts to channels you administer through an official Telegram bot, deploys configurable bot templates to your groups, and tracks delivery and growth metrics.

These Terms of Service, together with the Privacy Policy, Cookie Policy, Payment Policy, Refund Policy, Cancellation Policy and AML & KYC Policy, form the agreement between you and Antenna.

If they conflict, these terms prevail, except where a policy gives you more rights.

2. Definitions

"Account" means your Antenna account, keyed to your Telegram identity. "Channel" means a Telegram channel or group you connect to Antenna. "Content" means the text, media, templates and settings you create or upload.

"Credits" means the prepaid balance used to pay for the service. "Order" means a commissioned bot build or a specialist booking bought through Antenna. "Customer" means you or, where section 4 applies, the organisation you act for.

3. Forming the agreement

The agreement starts when you tick the box to accept these terms and sign in for the first time.

Each purchase of credits, and each order paid from your wallet, is a separate contract under these terms, formed when the payment or the order is confirmed on screen. We keep a record of what you accepted and when.

4. Buying for a business

Most channels on Antenna are run for a business, an agency or a client.

When you use Antenna for an organisation, that organisation is the customer under these terms and is responsible for the account and everything bought through it, and you confirm you are authorised to accept these terms on its behalf.

Rights that the law gives only to consumers, such as the statutory right to withdraw from an online purchase, apply to an individual buying for personal use and not to an organisation buying for its business.

Everything our policies promise, including refunds for posts that are not delivered and for unused credits, applies to every customer alike.

5. Your account

You sign in with the Telegram Login Widget and your account is keyed to your Telegram identity. You must be able to administer the channels you connect.

You are responsible for the content you publish through Antenna and for complying with Telegram's Terms of Service and applicable law in your jurisdiction.

Keep your Telegram account secure, including with Telegram's two-step verification: anything done in Antenna while you are signed in counts as done by you.

Tell us through the contact form at once if you think someone else has used your account.

6. Eligibility

Antenna is intended for people who are at least 18 years old, or the age of legal majority in their place of residence if that is higher, and who have the legal capacity to accept these terms.

By signing in you confirm you meet this requirement. If we learn an account belongs to someone who does not, we may suspend or close it.

Antenna is not available in Russia, Belarus, Iran, North Korea, Syria or Cuba: the site refuses connections from those countries, and you may not use Antenna if you live in or are established in one of them.

7. Connecting channels

To connect a channel you add Antenna's bot as an administrator with the rights needed to post. You confirm that you administer that channel or are authorised by whoever does.

You can disconnect a channel in Antenna or remove the bot in Telegram at any time; posts scheduled for that channel are then not sent and not charged.

8. Credits and payment

Antenna operates on prepaid credits. Channel broadcast posts are charged per delivered post, and AI-generated text, AI-generated images and translations are charged per use; a post that is not delivered is refunded.

DM sends are priced per delivered recipient and bot templates per enabled month, as shown on the pricing page.

Credits are purchased in advance, are denominated at a fixed anchor, do not expire, and are not e-money, a deposit or a stored-value instrument — they are a prepaid balance for this service.

That does not mean they can never come back to you as money: Unused credits are refundable for 14 days from the day they were bought; credits already spent on delivered work are not.

The Refund Policy and the wallet state the same rule in the same words. Payments are processed by licensed third-party payment providers; Antenna never holds customer funds and does not store payment credentials.

How payment works, including paying in euro or US dollars, is set out in the Payment Policy.

9. Commissioned builds and specialists

You can commission a custom bot build or book specialists through Antenna.

The scope, price, length and deliverables are shown before you pay and are recorded on the order page, which is the record of what was agreed and what was delivered.

Orders of €2,000 or more require an identity check first, as the AML & KYC Policy describes. Specialists work for Antenna, not for you directly, and Antenna remains responsible to you for their work.

Cancellation and refunds for orders follow the Cancellation Policy and the Refund Policy.

10. Your content

You keep ownership of your content. You give Antenna a non-exclusive, worldwide licence to host, copy, translate, format and transmit it only as far as needed to run the service for you, including delivering it to your channels and subscribers.

The licence ends when you delete the content or your account, except for copies we must keep by law or that sit in backups until they roll off. You confirm you have the rights to everything you publish through Antenna.

11. Acceptable use

You may not use Antenna to send unsolicited bulk messages, to operate lotteries that break local law, to distribute malware, to harass, or to publish content that is unlawful for you or your audience.

Rate limits and the automatic template kill-switch protect the shared bot's standing and may not be circumvented. We may disable a deployment or suspend an account that endangers the platform or other customers.

You must also not: attempt to gain access to other customers' accounts or data; probe, scan or test the security of the service without our written permission; reverse-engineer or scrape the service; resell access to it without our agreement; or use it to collect subscribers' personal data for purposes they did not agree to.

12. AI-assisted features

Some features use automated or AI-assisted processing: the broadcast composer's translation option produces machine-generated text appended to your post, and the bot-build estimate tool can read a written brief to suggest a scope.

These outputs are provided "as is", may contain errors, and are not professional, legal or financial advice — you review and remain responsible for anything you publish or approve.

You own the content you compose and the translated or scoped output generated for your account.

13. Our intellectual property

Antenna's software, design, bot templates, documentation and brand belong to us or our licensors.

These terms give you a right to use the service for as long as your account is open; they do not transfer any of our intellectual property to you.

Deliverables from a commissioned build are yours once the order is paid, as the order page describes.

14. Availability and changes

Antenna depends on Telegram's Bot API. Telegram outages, rate limits and policy changes may affect the service. We may change features with notice through the bot or the site; material changes to these terms will be notified in advance.

We aim to keep the service available at all times but do not guarantee uninterrupted service, and we may carry out maintenance, preferably at quiet hours.

If we withdraw a paid feature, unused credits bought for it remain refundable under the Refund Policy.

15. Suspension and termination

You may stop using Antenna and delete your account at any time from Settings.

We may suspend a deployment, a channel or your account at once where you break these terms, where the law requires it, or where the platform, Telegram's standing or other customers are at risk; we will tell you why unless the law prevents us.

We may close the service or your account for any other reason on 30 days' notice, and then refund unused credits in full. Sections 10, 13, 16, 17 and 19 continue after the agreement ends.

16. Liability

The service is provided "as is". To the maximum extent permitted by law, Antenna is not liable for indirect or consequential losses, lost audience or revenue, or for content removals by Telegram.

Nothing in these terms limits liability that cannot be limited under the law of your place of residence. Our total liability to a business customer in any 12-month period is limited to the amount it paid Antenna in that period.

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else the law does not allow to be limited.

17. Indemnity from business customers

If you use Antenna for an organisation, that organisation will reimburse Antenna for claims, fines and reasonable costs brought by third parties because of content it published through Antenna or because it broke these terms.

This section does not apply to consumers.

18. Changes to these terms

We may update these terms, for example when the service or the law changes. For a material change we will tell you at least 14 days in advance through the site or the bot.

If you do not accept it, you may close your account before it takes effect and receive a refund of unused credits. Continuing to use Antenna after the change takes effect means you accept it.

19. Law and disputes

These terms are governed by the laws of England and Wales, and the courts of England and Wales have non-exclusive jurisdiction. Consumers in the EU may also rely on the mandatory consumer protections of their country of residence.

If something goes wrong, contact us first through the contact form; we aim to answer within 5 working days and to resolve complaints within 30 days.

20. General

You may not transfer this agreement without our consent; we may transfer it to a company that takes over the service, and will tell you if we do.

If any part of these terms is found unenforceable, the rest remains in force. If we do not enforce a right straight away, we have not given it up.

Neither side is responsible for a delay caused by events outside its reasonable control, including Telegram outages. These terms and the policies listed in section 1 are the whole agreement between us about the service.
