Terms of use

1. General

These Terms govern the use of Guest Keeper, provided by NULLBIT d.o.o., Dravska ulica 17, 48000 Koprivnica, Republika Hrvatska, OIB 64593408110 (the Provider). The Privacy policy forms part of these Terms. Company details are in the Imprint. The Croatian version prevails.

2. Definitions

• Service – the Guest Keeper app for building, publishing and sharing digital guides for guests, with QR codes, translations, statistics and campaigns.
• Host (User) – an adult person or a company that opens an account.
• Team member – a person a host invites to their account.
• Guest – a person who uses a published guide.
• Subscription – a paid plan (Essential, Pro or Portfolio) that allows publishing guides and the other features listed on the plans page.

3. The contract

The contract is concluded electronically by opening an account and accepting these Terms, in Croatian. Using the Service confirms that you have read and accept them.

4. Account and team

Only adults may open an account. The host keeps the password safe and is responsible for what is done with the account. A host may invite team members with full or view-only access; billing and managing the team stay with the host. Report suspected unauthorised access to hello@nullbit.hr.

5. The Service and availability

The Service lets a host build guides, publish them at a public link, print QR codes for the property, its units and sections, translate automatically, see visit statistics, collect guest sign-ups and send campaigns. The Provider does not guarantee uninterrupted availability; planned maintenance is announced in advance where possible.

Automatic translations are machine-made and may contain errors. The host is responsible for the accuracy of what guests see.

6. Prices and payment

Building and previewing guides is free within the limits shown in the app; publishing a guide needs a Subscription. Prices are shown on the plans page and include VAT where it applies. Subscriptions are monthly or annual, paid in advance, and renew automatically until cancelled. Payment is processed by Stripe.

If a payment fails, the Provider may restrict publishing until it is settled; no content is deleted because of it. Amounts already paid are not refunded unless mandatory law requires it.

7. Cancellation and withdrawal

You may cancel a Subscription at any time on the Billing tab; cancellation normally takes effect at the end of the paid period, after which guides become private until a plan is chosen again. A host who is a consumer may withdraw within 14 days of the contract; if the service started at their request before then, they pay a proportionate part of the price.

8. Host obligations

• Use the Service lawfully and in line with these Terms.
• The host is responsible for guide content and must have the right to use the photos and texts they publish.
• A published guide is open to anyone with its link or QR code; the host decides which details (such as a Wi-Fi password, address or contacts) to publish.
• Unauthorised access, scraping, reverse engineering, overloading the Service and sharing credentials outside the team are prohibited.

9. Host obligations towards guests

For guest data collected through a guide the host is the controller and the Provider the processor. The host sends campaigns only to guests who signed up for them, imports no address lists without consent and respects every unsubscribe; the Service adds an unsubscribe link to every message and does not write to guests who have unsubscribed.

10. Liability

The Provider's total liability is limited to the amount the host paid in the previous 12 months. The Provider is not liable for indirect loss, lost profit, or data loss it did not cause. These limits do not apply to intent, gross negligence or harm to life or health, and consumers' mandatory rights are unaffected.

11. Intellectual property

The Service, its source code, design and the Guest Keeper name belong to the Provider. The host receives a non-exclusive, non-transferable right of use for the Subscription period. Content the host enters remains theirs; the Provider uses it only to provide the Service.

12. Suspension and termination

The Provider may suspend or close an account for a material breach of these Terms, unlawful use or a security threat, normally after a warning and a reasonable time to remedy it. The Provider may discontinue the Service with at least 30 days' notice by email and a pro-rata refund of amounts paid in advance.

You can ask for your account to be deleted, or for a copy of your data, at hello@nullbit.hr.

13. Changes to these Terms

Material changes are announced at least 15 days in advance, and price changes at least 30 days before they apply. Continuing to use the Service after a change takes effect means accepting it.

14. Governing law and disputes

Croatian law applies. We try to settle disputes amicably through hello@nullbit.hr; otherwise the competent court at the Provider's seat decides. Consumers keep their mandatory rights, including the court at their residence and out-of-court consumer dispute resolution.

15. Final provisions

If a provision is invalid, the rest remain in force. Written contact: NULLBIT d.o.o., Dravska ulica 17, 48000 Koprivnica, Republika Hrvatska, hello@nullbit.hr.
