Terms of use

1. Parties and scope

These terms are between Handooser LLC, a company based in New Mexico, USA, which provides the CesiSync service (the "Service", "we", "Handooser"), and the property owner or agency that opens an account ("you"). CesiSync is a product of Handooser LLC. By opening an account or using the Service you accept these terms.

For now the Service is offered mainly to businesses in Türkiye (owners, merchants and agencies); users in the EU/EEA/UK are not targeted. The Service is not a booking website and is not open to guests. It is a calendar, price and data network for property owners and agencies who act in the course of business.

2. Account and authority

The person opening an account declares that they are authorised to bind the business they represent and that the information given is correct and kept up to date. E-mail and phone verification are mandatory. You are responsible for keeping your password and API keys secret and must tell us immediately if you notice unauthorised use.

Agency accounts can only use limited features and the sandbox until their documents (for example tax certificate, TÜRSAB licence) have been reviewed and approved. The approval decision is ours and reasons are given.

3. Owner obligations

The owner is responsible for the accuracy of the information, photos, prices and business documents entered, for keeping the calendar up to date and for being entitled to let the property. Changes to fields such as name, address, type and licence number are reviewed before they go live; changes to descriptions, images, prices and the calendar apply immediately.

The owner accepts that agencies it approves, or that subscribe under direct approval, can see the calendar and prices. The owner may end a subscription at any time; ending stops new bookings but does not by itself cancel confirmed bookings.

4. Agency obligations

The agency may use data only for properties it subscribes to. It will not share this data (including the owner's contact details, address and prices) with third parties, resell it, or use it to build a competing network. The agency is responsible for its own offers to customers, for collecting payment and for the guest relationship.

As soon as an agency booking is placed the dates close for every subscriber. When a hold expires the dates reopen automatically. Entering bookings accurately and in good faith is the agency's duty; fake or speculative blocking may lead to account closure.

5. Payments and fees

CesiSync does not collect guest payments and is not a party to payment, commission or deposit arrangements between agency and owner. During the launch the per-transaction fee is 0%; this rate may change with prior notice. Owner plans are chosen by the limit of partner agencies and agency plans by the number of properties you can subscribe to.

Plans cost the same for owners and agencies and are billed monthly in advance in US dollars (Starter 19.90, Professional 39.90, Unlimited 49.90). As a launch offer every plan has a free trial for the first three months; nothing is charged before it ends, and the plan price is charged when it does. Payments run through PayPal; we never store your card details. If you save a payment method it is charged automatically at the end of each period; you can turn automatic renewal off or remove the saved method in the panel at any time, after which no fee is taken for a new period. Upgrades are prorated for the rest of the period and downgrades take effect at the end of it. Except where mandatory law requires otherwise, the fee for a period that has started is not refunded.

Invoices are issued in the name of Handooser LLC and appear in the panel. For unpaid invoices the account is warned first; if payment cannot be collected the plan expires and opening new subscriptions is suspended. Access to existing data and the right to download it are preserved. Prices exclude tax. On invoices to businesses in Türkiye no VAT is charged as long as the recipient declares it as the responsible party; once Handooser is registered for VAT, 20% VAT is added to the invoice. Elsewhere applicable tax may be added. Changes to plans and prices are announced at least 30 days before they take effect.

6. Your data is yours

You keep ownership of the data you enter. You grant us the limited right to use it that is needed to provide the Service. You can download your data at any time as JSON, ZIP, CSV or iCal; closing an account carries no fee or extra condition.

On a request to close an account, data is deleted or anonymised except for records we must keep by law or need for a dispute.

7. Unacceptable use

The following are prohibited: attempting unauthorised access, bypassing security measures, harvesting other people's data (including scraping) and circumventing API limits; overloading the Service; entering misleading or unlawful property or licence information; impersonating another person or business; and using the Service for unlawful activity.

On a breach we may warn, temporarily restrict access or close the account. In an urgent security risk we may act without prior notice and explain afterwards.

8. Availability and changes

We aim to run the Service continuously but do not guarantee it. Planned maintenance is announced in advance. API and webhook behaviour is versioned; incompatible changes ship in a new version with a transition period. Failed webhook deliveries are retried for about three days and events remain readable through the API.

9. Limitation of liability

The Service is provided "as is". We take technical measures to prevent double bookings, but information entered by owners, data arriving from external calendars (iCal) and third-party software are outside our control. To the extent the law allows we are not liable for indirect damage, lost profit or loss of reputation; our liability for direct damage is limited to the fees paid to us in the twelve months before the event. Intent, gross negligence and liability that cannot be limited by law are unaffected.

10. Intellectual property

The software, design, documentation and brand of the Service belong to us or our licensors. We give you a non-transferable, non-exclusive right to use the Service under these terms. You are responsible for the copyright in the photos and texts you upload.

11. Termination

You may close your account at any time. We may terminate an account on breach of these terms, non-payment or legal necessity with reasonable notice. Termination does not affect rights and obligations that have already arisen.

12. Governing law and jurisdiction

These terms are governed by the laws of the State of New Mexico, USA, excluding its conflict-of-laws rules; the courts of Bernalillo County, New Mexico have jurisdiction. Your rights under the mandatory data-protection (KVKK, GDPR), consumer and trade laws of your country, and your right to turn to the competent courts and supervisory authorities there, remain unaffected.

13. Changes and contact

We may update these terms. Material changes are announced by e-mail and in the panel at least 30 days before they take effect; if you do not accept a change you may close your account. Write to our support address with any questions.
