Terms of use

As of 21 October 2026. This English text is a translation for convenience; the German version (Nutzungsbedingungen) is legally binding. These terms apply to Bellchain: the app at app.bellchain.app including its interface (API), the Telegram bot @BellchainBot and the Pro, Trader and Community subscriptions.

1. Provider and contract

1.1 Bellchain is offered by Bjoern Blomquist, c/o JL Consulting Group GmbH #1797, Zürcherstrasse 84, 8852 Altendorf, Switzerland, email hello@bellchain.app (“we”). We answer questions and complaints at support@bellchain.app.

1.2 The contract for using Bellchain is concluded when you create an account, that is, when you redeem the sign-in link or the code from our email or sign in with Google or Apple for the first time. If you use the editor and the replay without an account, sections 2, 9 and 11 apply accordingly.

1.3 You pay for Pro, Trader and Community through Stripe Managed Payments. The price is collected by Sold through Link, LLC (“Link”), a company of the Stripe group, as merchant of record in its own name; Link pays the taxes and sends you receipts and invoices. Your payment to Link fulfils your payment obligation towards us. For the payment, Link’s terms (link.com/terms), which the payment page refers to, also apply. We are your contractual partner for the service, that is Bellchain with the plan you booked. You give notice of cancellation and withdrawal to us (sections 7 and 8) or to Link; we carry them out with Link. If you prepay with crypto (sections 6.7 to 6.13), we collect the payment ourselves, are the seller and issue the invoice to you.

1.4 Conflicting terms of users do not apply.

2. What Bellchain is and what it is not

2.1 With Bellchain, you build your own rules for price alerts from nodes (“chains”), test them on past prices (“replay”) and get notified when they match. Depending on the plan, an alert goes out by Telegram, web push, email, Pushover, ntfy, Discord, Slack, Microsoft Teams, Google Chat or webhook, or as a signal to your own trading bot.

2.2 Bellchain is not investment advice. We only report what you defined yourself. We do not judge whether a moment is good for buying or selling, give no recommendations and do not trade for you. Templates are examples of rules, not recommendations. You alone make decisions about purchases, sales and other transactions, at your own risk.

2.3 Bellchain does not connect to your account at an exchange, holds no crypto assets and no money and executes no orders. If you send a signal to a trading bot, the bot you set up yourself does the trading.

2.4 We get prices from crypto exchanges; the app shows which ones you can choose. We do not check them and give no guarantee that they are correct and complete. The replay calculates with past prices and says nothing about how prices will develop.

3. Account

3.1 You sign in with your email address by link or code, with a passkey or with your Google or Apple account; there is no password. An account belongs to one person and cannot be transferred.

3.2 Bellchain is for people aged 18 and over. By creating an account, you confirm that you are of age.

3.3 Keep access to your mailbox secure, because whoever can open it can sign in to Bellchain; the same applies to your devices and password managers holding passkeys, to connected Google or Apple accounts and to your API keys. Tell us without delay if your account is misused.

3.4 You can delete your account at any time in the settings. A running subscription then ends right away, and we refund the unused part of the paid period pro rata to your payment method, for a crypto prepayment under section 6.13.

4. Plans, limits and vouchers

4.1 There are the plans Free, Pro, Trader and Community. What each plan includes and costs, such as the number of active chains, the shortest candle timeframe, the replay period, the nodes and channels, the API and the number of notifications per day, is shown on the pricing page and in the app before every order. What is listed there as “Planned” is not part of the service.

4.2 Free costs nothing and needs no payment method.

4.3 If your account reaches its plan’s limit for notifications on a day, we send no more that day, and once the email limit is reached no more emails; the alerts are still listed under “Alerts”. The day follows your account’s time zone.

4.4 When a plan ends, Free applies. We delete nothing; chains that Free does not allow or that exceed its limit are paused.

4.5 Vouchers unlock a plan for the stated time, without payment. Each code works once. A voucher for the plan you currently have from a voucher extends it; you redeem a voucher for another plan after it ends. Vouchers cannot be paid out.

5. Trying Pro for 7 days

5.1 You can try Pro for free once for 7 days. To start, you add a payment method. Starting the trial concludes a Pro subscription whose first paid period begins after the trial.

5.2 Before the start, we tell you the price, the billing period (monthly or yearly) and the day of the first charge. Three days before that day, we remind you by email and, if you connected Telegram, by Telegram.

5.3 If you cancel during the trial, Pro ends right away and nothing is charged. If you don’t cancel, the trial turns into the paid subscription after 7 days.

5.4 The trial is available once per person. To check this, we store check values of your sign-in address, your Telegram ID and your card (privacy policy, section 6.7). If you already had a trial, a new one ends right away and without a charge; this also applies if you connect a Telegram account during the trial that already had one. Trader and Community cannot be tried.

6. Ordering, prices and payment

6.1 In the app’s order summary, you choose the plan, billing period and currency and see the price and conditions. “Continue to payment” or “Continue: add payment method” takes you to Link’s payment page. There you enter your payment method, check all details and complete the order with the order button, such as “Subscribe”; only then is the subscription concluded. Until then you can cancel at any time and correct your entries in the fields. The contract languages are German and English. These terms are permanently available on bellchain.app, and you receive a confirmation by email.

6.2 The prices shown in the app before the order apply. Euro prices are final prices and include VAT. Dollar prices are plus the tax due in your country; the payment page shows the final amount before you order.

6.3 Subscriptions are paid in advance, monthly or yearly, with the payment methods on the payment page, such as card, Apple Pay, Google Pay or Link. If you have a voucher running that already includes the booked plan, the first charge comes only when it ends.

6.4 If you switch to a larger plan or from monthly to yearly, the change applies right away, and the pro-rata difference for the current period is charged immediately. A smaller plan or a switch from yearly to monthly applies from the next billing date.

6.5 If a charge fails, your plan continues for another 7 days, and the payment is retried. If it does not succeed within that time, the subscription ends and Free applies.

6.6 We change the price of a running subscription only with your consent. If you do not consent, the previous price continues to apply; we may then cancel the subscription under section 7.6.

6.7 Prepaying with crypto. Instead of a subscription, you can prepay Pro, Trader or Community for one month or one year with USDC, EURC or SOL on the Solana blockchain. In that case we are the seller. If you live in the EU, you pay the euro price from section 6.2 with your country’s VAT included, also with USDC and SOL, which we convert at the current rate. A business in the EU with a valid VAT ID pays the same amount without VAT; it accounts for the tax itself (reverse charge). Outside the EU, USDC pays the dollar price, EURC the euro price and SOL the price in euros or dollars at the current rate of a crypto exchange; no VAT is added there. The app shows the amount in the token before you pay; it is valid for 24 hours for USDC and EURC and for 30 minutes for SOL. If the round amount is already taken by another open order, a surcharge of less than 1 cent is added so that every payment can be matched to exactly one order. We issue the invoice in the currency of the price, with the tax.

6.8 For tax purposes, you state the country you live in when you order, for a business the country where it is based. We compare it with the country of your connection; if the two don’t match, we don’t accept the order, unless it is a business with a valid VAT ID. We check a VAT ID with the EU (VIES). Paying with crypto isn’t possible from the United Kingdom and the Isle of Man; there you pay under section 1.3.

6.9 With “Buy now” you create the order, and the app shows you the amount, the receiving address and until when the amount is valid. You pay from a wallet you control yourself, to this address and with this amount. The contract is concluded when your payment arrives within the validity and is confirmed on the blockchain; the plan then applies immediately for the paid period, and we send you the invoice. If you don’t pay, the order lapses at no cost. For SOL, a payment of the stated amount still counts up to 2 minutes after it expires. If you pay without the app’s QR code or link, you must send exactly the stated amount; otherwise we cannot match a payment of a different amount to an order.

6.10 If a payment arrives after the validity or is lower than the amount, no plan applies; we refund what arrived (section 6.13). If you pay more, the plan applies; we refund the excess on request. We cannot reverse transactions on the blockchain; you bear the network fees of your payment.

6.11 A prepayment does not renew automatically. We remind you 7, 3 and 1 days before it ends by email and, if connected, via Telegram. If you extend with the same plan, the new period starts at the end of the current one; you can pay for a different plan after the end. When the prepayment ends, Free applies.

6.12 You cannot have a subscription through Link and a crypto prepayment at the same time.

6.13 We transfer refunds for crypto payments, for example after a withdrawal (section 8), when you delete your account (section 3.4) or under section 6.10, in the same token to a Solana address you give us: after a withdrawal and under section 6.10 the same amount that arrived, when you delete your account the unused part pro rata. We bear the network fee for this. If you don’t give an address, we ask you by email.

7. Term and cancellation

7.1 Monthly subscriptions run for one month and renew for one month at a time. You can cancel at any time, effective at the end of the paid month.

7.2 Yearly plans are fixed for the first year; if you cancel during the first year, the plan ends at the end of that year. After that, the plan continues indefinitely and is paid yearly in advance. You can then cancel it at any time with one month’s notice, and we refund pro rata what you paid beyond the end.

7.3 During the trial, Pro ends right away when you cancel (section 5.3). If a payment is outstanding (section 6.5), the subscription also ends right away when you cancel.

7.4 You can cancel

in the app under Settings → Plan and billing → “Cancel”,
without signing in via “Cancel contracts here” at the bottom of every page of the app and the website,
by email to hello@bellchain.app or by letter to the address in section 1.1.

We confirm a cancellation in the app or via “Cancel contracts here” right away by email, with date and time; a cancellation by email or letter as soon as we have processed it.

7.5 You can take back a cancellation at the end of the period in the app until then. This is not possible after a cancellation with a refund (section 7.2).

7.6 We may cancel a subscription with one month’s notice to the end of a paid period, a yearly plan in its first year at the earliest to the end of that year, and an account without a subscription with one month’s notice.

7.7 The right of both parties to terminate without notice for good cause remains unaffected. Good cause for us is in particular a serious violation of section 9, or one repeated despite a warning.

7.8 A crypto prepayment ends by itself with the paid period; you don’t need to cancel it. If you cancel it anyway, we confirm that, and it ends at the same time.

8. Right of withdrawal

As a consumer, you can withdraw from a subscription within 14 days of concluding the contract without giving a reason; for the Pro trial, the period starts with the trial. How this works and what applies then is explained in the information on the right of withdrawal. The easiest way is “Withdraw from contract” at the bottom of every page. We refund everything you paid for the subscription and do not charge for the time used. For a crypto prepayment, the period runs from the receipt of your payment; refunds are made under section 6.13.

9. What you must not do with Bellchain

9.1 Do not misuse Bellchain: no attacks on our systems, no automated mass requests outside the API and its limits, no circumvention of a plan’s limits or of the trial, for example with several accounts, and no reselling of access.

9.2 You send notifications only to targets that belong to you or where you are allowed to: to Telegram groups and channels only where you are an admin, to Discord, Slack, Microsoft Teams, Google Chat and webhooks only with the operator’s permission. The rules of these services apply.

9.3 You send signals only to trading bots that you run yourself for your own account. Bellchain is not meant for others to trade your signals automatically (copy trading).

9.4 If you share alerts with others, for example in groups and channels, you are responsible for the content. Do not present them as an investment recommendation from Bellchain, do not deceive anyone and observe the rules against market manipulation. The names and messages of your chains contain nothing unlawful and no advertising for third parties in other people’s groups.

9.5 If you violate this section, we may block the chains, targets or API keys concerned, where possible only after a warning, and in serious cases cancel under section 7.7.

10. Availability, defects and changes

10.1 We run Bellchain with care and check your chains as soon as a candle closes. Interruptions, for example due to maintenance or disruptions at exchanges and other services, cannot be ruled out; we do not promise a specific availability or delivery within a specific time. We announce larger planned maintenance in advance.

10.2 For delivery we use third-party services: Telegram, the browsers’ push services, email, Pushover, ntfy, Discord, Slack, Microsoft Teams, Google Chat and the recipients of your webhooks and bots. We have no influence on their availability.

10.3 In the event of defects, you have the statutory rights.

10.4 We keep developing Bellchain and change it when there is a valid reason, such as new or better features, changes to third-party services, security or changes in the law. This costs you nothing extra. If a change restricts more than insignificantly how you can use a paid subscription, we inform you by email at least 30 days in advance. You can then end the subscription free of charge within 30 days of this information, or of the change if it comes later, and get back the unused part pro rata.

11. Liability

11.1 We are liable without limitation for intent and gross negligence, for damage from injury to life, body or health, under mandatory product liability law and where we have given a guarantee.

11.2 For slight negligence, we are only liable for breaches of essential contractual obligations, that is, obligations whose fulfilment makes the performance of the contract possible in the first place and on whose observance you may regularly rely, and only for the foreseeable damage typical of the contract. Otherwise we are not liable for slight negligence.

11.3 Alerts are notices about rules you defined yourself, not recommendations. For lost profits and for losses from transactions you make or refrain from because of an alert or a missing alert, we are therefore only liable under sections 11.1 and 11.2.

12. Data protection

How we process personal data is explained in the privacy policy.

13. Changes to these terms

New terms apply to you only once you agree to them; we ask you by email or in the app. If you do not agree, the previous terms continue to apply to you, and we may cancel the contract under section 7.6.

14. Final provisions

14.1 Swiss law applies. If you are a consumer habitually resident in another country, you additionally keep the protection of the mandatory provisions of that country’s law.

14.2 We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.

14.3 These terms are available in German and English; the German version is authoritative.

14.4 If a provision is invalid, the others remain valid.
