SELLER (Service Provider):

Name: BY Sirius Group Ai and Technology Co Ltd.

Registered in: England and Wales — Companies House No: 17142392

Address: 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom

BUYER: the natural or legal person who provides name or company name, email and (if any) phone details in the registration/payment form. The Buyer is responsible for the accuracy of this information.

“Consumer” means a natural person acting for purposes outside their trade or profession; “Business Buyer” means a person who buys the service in the course of a business or profession (e.g. a salon, clinic, freelancer). Consumer-specific provisions (in particular Article 7) apply only to Consumers.

The Seller grants the Buyer access to the online appointment and business-management software service (SaaS) for the SiriPlan plan selected on siriplan.com (Mini, Starter, Pro, Business or other plans/add-ons offered by the Seller) under the terms below.

Plan scope, limits (e.g. staff count, monthly appointment/message quotas) and current prices are shown at checkout and at https://siriplan.com/fiyatlar. The plan, billing period (monthly/yearly) and amount shown at checkout form an integral part of this agreement.

The service is online access to software; no physical product is delivered.

The service is delivered electronically. Performance begins when payment is confirmed and the plan is activated on the Buyer's account; there is no physical delivery or shipping. An internet connection and a compatible device/browser are required.

The service starts once Stripe confirms the payment and the plan is assigned to the account. Service interruptions, maintenance and limitations of liability are governed by the Terms of Use (https://siriplan.com/kosullar).

The price is the amount shown at checkout for the selected plan and period (monthly or yearly) and is charged in the displayed currency (TRY, USD or EUR). Payment is made in advance by credit/debit card through the Seller's payment provider Stripe. Card details are processed by Stripe and are not stored by the Seller.

Because payment is processed through the Seller's merchant account outside Türkiye, the Buyer's card issuer may charge commission, exchange-rate or foreign-transaction fees. Such fees belong to the Buyer's bank, are not added by the Seller and are outside the Seller's control.

An electronic invoice/receipt is sent by Stripe to the Buyer's email address for each payment.

The Seller is a company registered in England and Wales; it is not established in Türkiye and has no tax representative in Türkiye.

The prices shown are total and final amounts; no additional tax or fee is charged beyond the amount shown. As the Seller is below the UK VAT registration threshold, it currently does not charge VAT and does not show a VAT amount on invoices.

Because the Seller is established abroad, the electronic invoice/receipt issued through Stripe for each payment does not replace a Turkish VAT e-invoice or e-archive invoice. If, under the law of the Buyer's country, the Buyer has further declaration, registration or payment obligations (e.g. a Business Buyer's bookkeeping of expenses or declarations on services obtained from abroad), assessing them is the Buyer's responsibility; the Seller does not provide tax advice.

Price changes are made only under the notice procedure in Article 6 and only for subsequent periods; a later tax registration of the Seller does not retroactively change the amount the Buyer paid for a period.

The subscription is paid in advance for the selected period (1 month or 1 year) and renews automatically at the end of each period at the then-current plan price, charged to the saved card, unless cancelled by the Buyer.

The Buyer may cancel at any time in the panel (Settings → Subscription) or by emailing info@bysirius.com. Cancellation stops the next renewal; the Buyer keeps access until the end of the paid period. No pro-rata refund is given for a period that has started, without prejudice to the Consumer's statutory withdrawal and refund rights (see Article 7 and the Refund & Cancellation Policy).

The Seller may change plan prices or scope. A price increase does not affect the current period and is announced by email/panel notice at least 30 days before the next renewal. If the Buyer does not accept the new price, they may cancel before renewal. Where the Seller has announced a fixed-price guarantee, the price will not be increased during that period.

The free trial (14 days) is offered to evaluate the service without payment and may not require card details. When the trial ends, the service may be restricted unless the Buyer purchases a paid plan. A paid plan starts when payment is received.

Plan changes: on an upgrade, the unused part of the current period is credited and the difference is charged, and a new period starts at the upgrade; on a downgrade, the current period is kept, the unused difference is applied as account credit and no cash refund is made. Details are in the Refund & Cancellation Policy.

Under Turkish Consumer Protection Law No. 6502 and the Distance Contracts Regulation, a Consumer may withdraw within 14 days without giving any reason and without penalty. However, the legislation provides that the right of withdrawal cannot be exercised, or can be exercised only in a limited way, for services performed instantly in electronic form and for services whose performance begins with the Consumer's consent before the withdrawal period ends.

By the separate consent given at checkout, the Consumer expressly confirms that they request the service to start immediately after payment (before the withdrawal period ends), that the service is performed instantly in electronic form, and that they will lose the right of withdrawal once performance has begun.

If a competent authority or court holds that this consent/exception is not valid in the specific case, or if the Consumer withdraws in writing before performance begins: the Consumer sends the withdrawal notice to info@bysirius.com; the Seller refunds the amount for the unperformed (unused) part to the payment method used, within 14 days at the latest after receiving the notice. If the service has been used at the Consumer's request during that time, the Consumer bears the pro-rata (daily) price for the part actually used until the withdrawal date.

The sample form in the Refund & Cancellation Policy may be used for the notice (it is not mandatory). Business Buyers are not consumers and have no right of withdrawal.

The Buyer is responsible for protecting their account and password, using the service lawfully and in line with the Terms of Use, and for the content and personal data uploaded to the service (including data of their own customers) and its legal compliance (including KVKK/UK GDPR notice and consent obligations).

The Buyer may not endanger system security, copy, reverse-engineer, scrape or unlawfully resell the service. In case of breach, the Seller may suspend or terminate the service.

The Seller undertakes to provide the service with due care and reasonable technical standards; it does not guarantee uninterrupted or error-free service, or any particular business result or revenue increase. To the extent permitted by law, the Seller is not liable for disruptions caused by third-party services (WhatsApp/Meta, SMS carriers, payment institutions, hosting providers, etc.) or their rule changes.

For Business Buyers, the Seller's total liability under this agreement is limited to the fees paid by the Buyer for the relevant plan in the 12 months before the event, save for wilful misconduct, gross negligence and cases where mandatory law does not allow limitation. Mandatory consumer-protection provisions for Consumers are not affected by this article.

Neither party is liable for failure to perform due to force majeure (natural disasters, war, epidemics, network/infrastructure/power outages, legal changes, third-party platform restrictions, etc.).

The Buyer's personal data is processed to provide the service, for payment and invoicing, legal obligations and communication, in accordance with KVKK No. 6698 and applicable law. See the Privacy Policy (https://siriplan.com/gizlilik) and the KVKK Notice (https://siriplan.com/kvkk).

As evidence of consent, the consent date and time, the version of the accepted text, the Buyer's account ID, IP address and browser information are securely recorded and retained for the statutory retention periods.

Turkish law applies to this agreement. For Consumers, the right to apply to Consumer Arbitration Committees (within the monetary limits in force) or Consumer Courts at the Buyer's place of residence or where the service was purchased is reserved (these remedies are mandatory).

For Business Buyers, the Courts and Enforcement Offices of Istanbul have jurisdiction.

The parties agree that electronic records (server/log records, emails, payment records, consent records) are conclusive evidence under Article 193 of the Turkish Code of Civil Procedure No. 6100.

Notices to the Buyer are sent to the Buyer's registered email address or through an in-panel notice. The Buyer must keep their email address up to date; a notice is deemed given when sent.

The Turkish text is authoritative; translations are for convenience and the Turkish text prevails in case of conflict. The invalidity of any provision does not affect the validity of the others.

This agreement takes effect when the Buyer ticks the consent boxes at checkout and completes payment. The Buyer can always view a copy of the version in force at the time of consent on this page.
