1. Who we are

Felku Connect is a Felku service, operated by Paulo Henrique Reis Alves (sole proprietor), CNPJ 65.508.556/0001-39, headquartered at Av. Eng. Luiz Carlos Berrini, 1681, conj. 111 e 112, Cidade Monções, São Paulo, SP, Brazil, CEP 04571-011 ("Felku", "we"). It is the same business that operates Felku's sticker bot and app, but Felku Connect is a separate service, with these Terms of its own.

By creating an account and ticking the acceptance box at sign-up, you ("you", "customer") agree to these Terms and confirm you have read the Privacy Policy. The acceptance records the version of both documents. If you use the service on behalf of a company, you confirm you have the authority to accept them for it.

You must be 18 or older to use the service.

2. The service

Felku Connect is an MCP (Model Context Protocol) server that connects your WhatsApp and your Telegram bot to the artificial intelligence agent that you choose and configure (for example, Claude, Cursor, Codex or Hermes). With it, your agent can read the chats you allow and send messages through your accounts.

In short:

WhatsApp: you connect your number by scanning a QR code or typing a pairing code, as you would to use WhatsApp on another device. Felku then works as a device linked to your number.
Telegram: you create a bot on Telegram and give us its token. We use Telegram's official bot API.
Contact list: your agent only reads and only replies to the chats you put on your account's contact list (one list for WhatsApp and another for Telegram). The connection's own number is added automatically on WhatsApp. How many contacts fit on the list depends on the plan (see the plans). During the free trial: on WhatsApp, you and 2 more contacts from the list; on Telegram, 1 one-to-one chat (Telegram groups and channels are not supported).
Sending limits: every send goes through pacing control on our server: randomized intervals, hourly and daily caps that start low on a new connection, sending hours, a first-message cap and an automatic pause. These limits lower the risk of your number being restricted; they don't remove it (see section 3). Sending limits are the same on every plan. We may tighten them when that lowers the risk for connected numbers; we'll let you know in the dashboard.
Automatic pause. To protect your number, the server adds up risk signals from the connection: drops, send failures, repeated reconnections and restriction warnings from WhatsApp. When the total crosses the threshold described in Limits, the connection pauses on its own. While paused, nothing is sent and your agent gets the reason; reading keeps working; stored messages, your contact list, keys, plan and billing stay the same. An automatic pause is a protection, not a penalty: it isn't an account suspension and doesn't count as a breach of these Terms. Only a person with dashboard access can resume the connection. Check the reason before resuming; if it was a restriction warning, we recommend waiting a few hours and sending less. Pausing a single chat: when your agent exchanges too many automatic messages with the same person in a short time, only that chat pauses, until you write in it or resume it in the dashboard.
Our pauses. Two pauses aren't resumed by you, because they don't depend on your number: (a) a general pause we apply to all connections for safety (for example, WhatsApp instability), with the reason shown in the dashboard; and (b) when your number's server loses contact with our dashboard for more than 24 hours, it only receives and stores messages, without sending. Both come back on their own when the cause is over.
Direct sending: when your agent asks to send a message, it goes out right away, without going through you, within the sending limits above. If it wants, the agent can first ask for a preview, which shows what would be sent and when, without sending anything. Two cases are held until you confirm in the dashboard: (a) sending to a different chat right after reading messages from someone else (for a short period); (b) forwarding to another chat a link or media that came from someone else. The confirmation expires after a short time; after that, the agent must ask to send again. Some sends stay blocked until you change something in the dashboard: a destination outside the contact list, high-risk actions (off by default), a paused connection and, during the free trial, any send outside you and the 2 contacts on the list (WhatsApp) or the allowed chat (Telegram). The first message to someone on the list who never talked to the number is capped at 3 per day, on every plan; beyond that, it is denied until the next day.
Your agent, your choice: the AI agent and the AI service it uses (for example, Anthropic, OpenAI, Google) are not provided or controlled by Felku. When your agent reads a message through Felku Connect, the content goes to that service under the terms you accepted with it.
Optional features (not available yet): history import and received media are off and, today, cannot yet be turned on in the dashboard. When they are released, you will turn each one on yourself, per connection, with a recorded acceptance, and these rules will apply:
- History import: brings the earlier text messages of the one-to-one chats on the contact list (groups are left out), only as far back as your plan's retention period. Your agent reads that history for reference only: it is not treated as a new message. Turning the switch off or disconnecting immediately deletes that connection's imported history.
- Received media: your agent may ask for the file of an image or document that arrived in a chat on the contact list, up to 5 MB, within the first 15 minutes after it arrived. We do not keep the file: it goes straight to the agent.

Felku Connect is not a bulk messaging, marketing or CRM service.

Availability: we work to keep the service up, but we do not promise continuous availability or any uptime percentage. The WhatsApp connection can drop and need to be redone, including because of changes made by WhatsApp itself. When the connection drops, the dashboard shows its state and your agent can see it through the status tool; today we do not send a drop email.

3. Unofficial connection and risks

Read carefully. See also the Security and risks page.

The WhatsApp connection made by Felku Connect is not official. Felku is not affiliated with, sponsored or approved by WhatsApp, Meta or Telegram. "WhatsApp" and "Telegram" are trademarks of their respective owners.
Using WhatsApp through an unofficial connection may go against WhatsApp's terms. WhatsApp may, at any time and without notice, limit, suspend or ban your number, temporarily or permanently. Felku has no control over that decision and cannot reverse it.
The sending limits reduce the risk but do not remove it. No provider of unofficial connections can guarantee that a number will not be restricted.
We strongly recommend using a dedicated number (not your main personal number or your company's main number), not keeping other unofficial systems linked to the same number, and not publicizing that number to strangers.
By connecting, you confirm that you understand this risk and that the decision to connect your number is yours.

What we do to lower the risk: pacing control on our server (randomized intervals, sending hours, hourly and daily caps that grow with the connection's age, a first-message cap and a repeated-content limit); a mandatory contact list; warnings about devices linked to the number; an automatic pause when risk signals appear. Details are in Limits. None of this is a guarantee.

If your number is restricted or banned: the decision is WhatsApp's, and we can't appeal or reverse it for you. When WhatsApp warns of a restriction, the connection pauses on its own and we don't reconnect on our own. Your Felku account stays active, and you can connect another number within your plan's limit. We don't help get around a restriction: connecting a new number to keep up the kind of sending that led to the restriction breaches section 5. The same applies to restrictions Telegram places on your bot.

4. Account and access

To create the account, we confirm your email with a 6-digit code. Password recovery is also done with a code sent to your email.
You must provide true information at sign-up and keep it up to date, especially your email, which we use for account, billing and security notices.
You are responsible for your account password and for the access keys (MCP keys) you generate. A key gives the agent access to whatever its scope allows: treat it like a password. You can revoke a key at any time in the dashboard.
The WhatsApp connection and the Telegram bot token are credentials of your account on those services. We store both encrypted, with the encryption key kept separately, and never return them through any tool.
You are responsible for what your agent does with the keys you gave it, including messages it sends without your review. Since sending is direct (section 2), review your agent's instructions and permissions before connecting it.
If you suspect unauthorized access, revoke the keys, disconnect the number and write to contato.suporte@felku.com.br.

5. Acceptable use

You may only use Felku Connect for lawful purposes. It is forbidden to:

Send spam, bulk messages or unsolicited messages.
Make cold contact: message people who did not ask to receive messages, have no relationship with you or did not consent.
Send or store illegal content, including child sexual abuse or exploitation material, content that infringes third-party rights, fraud, scams, phishing, hate speech, threats or harassment.
Try to bypass, disable or get around the sending limits, plan limits or security mechanisms (for example, by creating several accounts or splitting sends across numbers to escape the limits).
Resell, sublicense or offer Felku Connect to third parties as your own service without a written contract with Felku.
Connect a number or bot that is not yours or that you are not authorized to use.
Process your contacts' personal data without a legal basis, or in breach of Brazil's General Data Protection Law (Law 13.709/2018, LGPD).
Attack, overload, reverse-engineer or test the security of the service without written authorization.

Your contacts are yours: you are responsible for having a legal basis to process their data and for telling them, where the law requires, that an AI agent may read and reply to the messages. Take extra care with contacts under 18: do not put chats with children or teenagers on the contact list without a legal basis for it.

Who is responsible for which data. For your account, billing and service-usage data, Felku is the controller. For the messages in your conversations and the data of the people you talk to, you are the controller and Felku is the processor: we handle that data only to provide the service, following your instructions (what you connect, your contact list, your plan's retention period). The companies that help us with this part (sub-processors) are listed in the Privacy Policy; we give advance notice of changes to that list. If your company needs a data processing agreement (DPA), ask at contato.suporte@felku.com.br.

5.1 Normal use. Felku Connect is built for AI agents. Automation, several agents using keys from the same account, and continuous use throughout the day are normal use. High volume within the sending limits is not, by itself, abuse. "No per-message fees" means we don't charge per message sent or read; it doesn't mean unlimited sending.

5.2 Abuse includes, in addition to what this section already forbids: (a) bulk sending, broadcast lists, campaigns or blasts, even when split across agents, keys, connections or accounts; (b) sharing, lending or selling keys to anyone outside your account; (c) using your account as the infrastructure of a product in which other people connect numbers or use an agent through your account, without a written contract with Felku; (d) connecting another person's or company's number without the holder's written authorization; (e) disguising your sending pattern to get around the limits (swapping letters, re-encoding files, rotating numbers to add up limits); (f) deliberately overloading the service.

5.3 Agencies and service providers. You may operate your clients' numbers when each client authorizes it in writing, is responsible for the legal basis for their own contacts, and each number takes up one connection in your plan. Offering Felku Connect under your own brand, or charging third parties for access to it, requires a written contract with Felku.

6. Plans

The plans, what each one includes (connected numbers, keys, contacts on the list, message retention and features) and the prices are on the plans page, which shows a summary of the conditions before you subscribe. Prices are in Brazilian reais (BRL), charged by credit card only, on a recurring monthly or annual basis, according to the chosen plan.
Plan limits. Each plan has limits on WhatsApp connections (Telegram is included), access keys, contacts on the list per channel, and how long received messages are kept. The numbers for each plan are on the plans page, as shown there at the time. When you reach a limit, you can't add contacts, create keys or connect numbers until you remove one or upgrade; received messages are deleted once they pass the retention period. No plan is unlimited. "No per-message fees" is about price, not capacity.
Payments are processed by Stripe. Felku does not receive or store your full card number. Your receipt and invoices are available in the dashboard, under Account, through Stripe's payment portal. On the payment page, receipts and the Stripe portal, plans appear as Personal, Pro and Business.
Annual plan: about 7 days before renewal, we email you the date, the amount and the link to cancel or change your card. If the renewal happens and you don't want it, you can ask for a refund of it as described in section 8.
Upgrading: takes effect immediately; we charge the difference prorated for the remaining period.
Downgrading: takes effect at the end of the period already paid. If the new plan allows fewer numbers, you choose in the dashboard which ones stay connected; the others are disconnected and deleted when the period turns. If you don't choose, the oldest ones stay and the others are paused for 7 days and then disconnected and deleted, with no way to recover them. The message retention period becomes that of the new plan.
Coupons: promotional coupons apply under the conditions stated in each coupon.
Declined payment: we let you know by email and in the dashboard. For 7 days the service keeps working. If the payment is not settled in that period, sending messages is blocked and the subscription is also canceled at Stripe, so your card is not charged again. We email you about the cancellation. Connections and messages are not deleted because of this: reading continues so you can look up and delete your data, and messages follow the plan's retention period.
Price changes: we may change prices. The change applies from the next renewal, with at least 30 days' notice by email. If you don't agree, you can cancel before the renewal.

7. Free trial and cancellation

Paid plans start with a free trial (today, 7 days; the length in force is shown on the plans page and at checkout) and require a credit card when you subscribe. During the trial: 1 connected number, and your agent only talks with you and up to 2 contacts from the list on WhatsApp and with 1 one-to-one chat on Telegram (the first one you add; Telegram groups and channels are not supported).
If you don't cancel before the trial ends, the first charge is made the next day, on the chosen plan, and then renews automatically each period. The dashboard shows how many days are left, the date and amount of the first charge and how to cancel. We email you before the trial ends.
One trial per person. To start the trial, you must confirm your email. We check whether that email or that card has already had a Felku Connect trial in the last 24 months, even in an account that was deleted. For that we keep only a code derived from the email and from the card identification Stripe gives us (not the card number), as the Privacy Policy explains. If there was already a trial, the subscription starts without a trial or is canceled immediately, with no charge, and we email you; you can subscribe without a trial.
Canceling is simple: in the dashboard, under Account › Cancel subscription, at any time, without talking to anyone. If you cancel during the trial, nothing is charged. If you cancel later, the service continues until the end of the period already paid and there is no new charge; until then you can resume it.

8. Refunds

Right of withdrawal: since the purchase is made online, you can withdraw within 7 days and get back what you paid (Brazilian Consumer Protection Code, art. 49). Since the free trial charges nothing, we count those 7 days from the first charge: if you ask within 7 days of it, we refund the full amount, whether you used the service or not. The same applies to the annual plan renewal: within 7 days of the renewal charge, we refund it in full. This period does not change with the length of the trial.
How to ask: in the dashboard, under Account › Withdraw and get a refund, which records the request and confirms receipt right away, on screen and by email. You can also write to contato.suporte@felku.com.br with the subject "Estorno Felku Connect", saying which charge you want refunded (date or amount); preferably from the account email or, if that's not possible, stating the registered email. You don't need to explain why.
Timing: we issue the refund on the same business day we confirm the request (at the latest on the next business day), to the same card that was charged. The refund through Stripe already notifies the card issuer of the cancellation of the transaction, as required by art. 5, § 3, of Decree 7.962/2013. After that, the time for the credit to show on your statement depends on your bank (usually the next statement).
What happens to the account: together with the refund, the subscription ends immediately, with no new charge. Paid access ends and sending messages is blocked. Your account keeps existing until you delete it, and you can subscribe again (without a new free trial).
Outside the withdrawal period, we do not refund periods already started, including prorated amounts, except where the law requires it or where the problem was caused by our failure.
Restriction or banning of the number by WhatsApp does not entitle you to a refund, because it is a risk disclosed in section 3 and a decision made by WhatsApp, outside our control, unless the restriction was caused by a Felku failure, for example a defect that let messages go out above the published limits. This does not affect the right of withdrawal within the legal period.
Duplicate, unauthorized or erroneous charges by us: we refund the full amount at any time, outside the 7-day period, through the same process above.
Service failures attributable to Felku (for example, a prolonged outage caused by us) are reviewed case by case.
Before opening a dispute (chargeback) with your bank, talk to us: a direct refund is usually faster.

9. Limitation of liability

To the extent permitted by law:

The service is provided as is. We do not guarantee that it will be uninterrupted, error-free or compatible with any AI agent.
Felku is not liable for: (a) restriction, suspension or banning of your number by WhatsApp or of your bot by Telegram; (b) what your AI agent does, decides or sends, and what the AI service you chose does with the data it receives; (c) messages sent with your keys, unless caused by a Felku failure; (d) loss of messages during connection drops, unless caused by a Felku failure; (e) unavailability of WhatsApp, Telegram or third-party services; (f) lost profits, lost customers or lost business opportunities.
If you subscribe as a business and are not an end consumer, Felku's liability, if any, is limited to the total you paid us in the 12 months before the event. If you are a consumer, the Brazilian Consumer Protection Code applies.
Nothing in these Terms excludes liability that the law does not allow to be excluded, including in case of willful misconduct or gross negligence by Felku.
You agree to indemnify Felku for losses and third-party claims caused by your use in breach of these Terms or the law (for example, spam sent by your agent).

10. Suspension and termination

By you: you can cancel the subscription and delete the account at any time in the dashboard.
By Felku: we may pause a connection, suspend or close your account if: (a) you breach these Terms, especially section 5; (b) there are signs of abuse, a security risk or a risk to other customers; (c) there is a court order or legal requirement; (d) the payment is not settled within the period in section 6.
Whenever possible, we let you know in advance and tell you why. In case of serious abuse or a legal requirement, the suspension may be immediate.
Suspension for breach of these Terms does not entitle you to a refund.
When you disconnect a WhatsApp number or a Telegram bot, we immediately delete from our database the credential and the stored messages of that connection.
When you delete the account, it is deleted immediately, together with the connections, credentials and messages. Some records must be kept for a legal period, as the Privacy Policy explains.
Felku may discontinue the service with at least 30 days' notice, refunding the prorated amount of paid and unused periods.

11. Changes

We may update these Terms. The version and effective date are at the top of this page, and the acceptance at sign-up records the version you accepted.
Relevant changes (for example, to price, billing, refunds or liabilities) are announced by email and in the dashboard at least 30 days in advance. If you don't agree, you can cancel before the change takes effect; continuing to use the service after that means you accept the new version.
Changes required by law or for security may take effect immediately.

12. Governing law, venue and contact

These Terms are governed by Brazilian law, including the Consumer Protection Code, Decree 7.962/2013 (e-commerce), the Brazilian Internet Civil Framework (Law 12.965/2014) and the LGPD.
If you are a consumer, you may file a lawsuit in the courts of your domicile. In other cases, the courts of São Paulo, SP, Brazil are chosen, the same as for Felku's other services.
Before going to court, please talk to us: we try to resolve it within 10 business days.
