Terms of Use — Desta

Last updated: 26 September 2026

1. Operator and agreement

Desta is provided by Dinzel IT d.o.o. (Dinzel IT društvo s ograničenom odgovornošću za računalne djelatnosti i usluge), Ulica Lea Müllera 43, 10090 Zagreb, Croatia, OIB 94890617087. Contact dinz@dinzzz.com, or write to that address, for support, complaints and legal notices.

These terms govern our Desta service. Apple's applicable App Store terms and standard application EULA apply within their respective scope unless a valid custom EULA has been supplied through Apple. These hosted terms do not themselves replace the EULA selected in App Store Connect. Mandatory consumer rights remain unaffected.

2. Accounts and use

Provide accurate account information and keep login credentials secure. Notify us of suspected compromise. You are responsible for use you authorize, but are not automatically responsible for every unauthorized incident. You must have legal capacity to enter the agreement or the legally required authorization of a parent or guardian. A person acting for an organization must have authority to do so.

You may use Desta for your own planning and information, including in your work, subject to the applicable licence and data rights. This does not authorize resale of underlying datasets, operation as a rescue service or use as certified navigation equipment.

3. Marine information and limitations

Desta supplies forecasts, estimates and planning aids. Conditions can change quickly and differ from what is shown. It is not an official nautical chart, certified navigation system, rescue service or replacement for a lookout and competent seamanship. Consult official forecasts, up-to-date nautical charts and Notices to Mariners. In Croatia, relevant official services include DHMZ and HHI.

Suggested routes, headings, departure times and boating scores do not establish safe or navigable passage. They may omit depths, obstructions, restricted waters and local conditions. Tide predictions, including port-referenced data, and fallback estimates do not establish under-keel clearance. Check timestamps, sources and actual conditions.

Anchor-watch and daylight alerts depend on position accuracy, permissions, battery, settings and iOS operation. Alerts can be delayed or absent; maintain a proper watch. Radar and rain-arrival estimates depend on provider availability and do not guarantee rain timing or detection of squalls. Desta does not contact emergency services. You remain responsible for operating your vessel and caring for your crew.

For applicable WeatherKit real-time guidance: YOUR USE OF THIS REAL TIME WEATHER GUIDANCE APPLICATION OR WEBSITE IS AT YOUR SOLE RISK. WEATHER DATA MAY NOT BE ACCURATE. This notice does not exclude rights or liability that law does not allow us to exclude.

4. Pro plans, prices and billing

Features, the full localized price and applicable offer conditions are displayed before purchase. A Desta account is currently required to link and restore Pro access.

Apple processes in-app payments through your Apple account. A trial or special offer applies only if displayed and you are eligible. Manage or cancel renewable subscriptions in Apple subscription settings before the renewal deadline shown by Apple. Cancellation normally stops future renewal, with access through the paid period, subject to refunds or other applicable remedies. Fixed-duration passes expire without another charge.

Deleting the app, signing out or deleting a Desta account does not by itself cancel Apple billing. Account deletion remains available while a subscription is active. Use Restore Purchases or contact support if paid access is not recognized, including after account deletion. Service availability, coverage, device compatibility and connection/permission requirements can affect individual features; purchase information must accurately describe available benefits.

5. Withdrawal, refunds and conformity

You retain applicable rights concerning withdrawal, non-supply and conformity of digital content/services. Where EEA distance-contract withdrawal rules apply, the usual period is 14 days. Whether early supply affects that right depends on the contract type and legally required consent, acknowledgment and confirmation. Agreeing to these terms alone does not waive withdrawal rights.

You can request an App Store purchase refund through Apple's purchase-reporting service and contact us about non-supply, access failures or statutory claims. Apple's process does not remove a remedy you have against us under applicable law. Where required, remedies include correction, price reduction or termination/refund. Mandatory consumer guarantees, including applicable Australian guarantees, remain in force.

Where withdrawal is available, you may notify us through the contact above with an unambiguous statement identifying yourself, the service/purchase and purchase date. Optional form: “I withdraw from my contract for [service/purchase], ordered on [date]. Name: [name]. Address: [address]. Date: [date].” Sign only if using paper. This is not your exclusive lawful method; any applicable statutory online withdrawal mechanism and Apple purchase rights remain available.

6. Written complaints

Send complaints to dinz@dinzzz.com or Dinzel IT d.o.o. at the registered address above. Include enough detail to identify the issue; do not send passwords or verification codes. We acknowledge receipt without delay and answer consumer complaints in writing within 15 days, stating whether we accept their grounds. We retain the statutory complaint record for one year, with specific further retention only where another lawful basis requires it.

If a complaint is unresolved, we will provide applicable information about competent alternative dispute-resolution bodies and whether we are required or willing to participate. These terms do not claim membership in a particular scheme or limit access to courts or regulators.

7. Updates, changes and termination

We provide updates necessary to maintain conformity, including security updates, for the period required by law. Install necessary updates we notify you about and use a compatible supported device.

We may change the service for valid reasons such as security, legal requirements, interoperability or licensed-data availability. Changes must meet applicable digital-service rules, including required notices, no additional cost for qualifying modifications and appropriate advance notice on a durable medium. If a change negatively affects paid access beyond the legally permitted threshold, applicable termination, refund and other rights remain available.

We may proportionately restrict access for material breach, fraud or serious security/legal risk. Where reasonably possible, we explain the reason and allow correction; urgent protective action may be immediate. Contact us to challenge an error. This does not permit arbitrary forfeiture of paid access. If we discontinue a paid service, we provide legally required notice and treatment of unused paid access.

8. Intellectual property and acceptable use

Desta and third-party content belong to their respective rights holders. Use rights do not transfer ownership. Do not bypass access controls, access another person's account, interfere with the service, infringe rights or redistribute protected datasets without permission. Applicable mandatory legal exceptions remain available.

Provider attribution and licence notices must remain intact. You may not reverse-engineer WeatherKit or Apple Weather data except where a mandatory legal right overrides the restriction. Authorized use of Desta does not grant a licence to resell underlying weather, map, harbour or tide datasets.

9. Liability and applicable law

Forecast uncertainty and stated limitations do not remove our legal service obligations. Nothing here excludes or limits fraud, intentional wrongdoing, gross negligence, death or personal injury where liability cannot lawfully be excluded, mandatory consumer remedies or any other non-excludable liability. Consumers are not required to indemnify us for every claim arising from use of Desta.

Croatian law governs our service agreement without depriving consumers of applicable mandatory protections of their habitual residence. These terms do not require consumers to litigate only in Zagreb or waive competent courts or regulators.

10. Privacy and term changes

The Privacy Policy explains data processing and choices. Accepting these terms is not blanket consent to optional processing. We provide appropriate notice of material changes and obtain agreement where required. Continued use does not automatically waive rights or authorize retroactive changes to a paid agreement. Mandatory law prevails over an invalid provision; remaining valid provisions continue to apply.
