Android End User Licence Agreement

01Effective date and existing users

This text is issued with effect from 4 October 2026. The Privacy Policy describes processing and does not require blanket consent. New contractual terms apply to existing users only after proper notice and valid agreement or another lawful change procedure; publication alone does not rewrite earlier contracts.

02Provider and agreement

SilkIdea s.r.o., company number 07990073, VAT ID CZ07990073, registered office: Kosova 1242/1c, Suchdol, 165 00 Praha 6, Czech Republic. Registered in the Commercial Register maintained by the Municipal Court in Prague, Section C, File 311152. Contact: info@silkidea.com; telephone +420 724 672 400.

These terms supplement the information and offer provided before a purchase or feature is ordered. They apply when made available and validly agreed for that purchase or service. Posting a new version on the website does not retrospectively change existing contracts. The Privacy Policy explains data processing; reading it is not blanket consent to processing.

03Licence grant

After lawful acquisition and acceptance of this agreement, SilkIdea grants a non-exclusive licence to install and use coolAltitude on compatible devices you own or lawfully control, for personal or professional purposes within the purchased or freely provided features. The licence lasts for the access period agreed in the offer; a one-off licence has no recurring fee. Store rules on devices, accounts and sharing apply.

04Scope and restrictions

Do not resell, rent, distribute, bypass paid-feature protections or disrupt the app without permission. Restrictions on reverse engineering, modification or copying do not apply where mandatory law permits those activities, particularly for interoperability. App rights remain with SilkIdea or the respective rights holders. Separate third-party component licences take precedence for those components.

05Required operator approval

Before approval, the app is only an auxiliary information and training tool outside actual operational decision-making. Approval must cover the particular functions, version and conditions of use. Even after approval, it does not replace approved documents and may be used only within the approved scope. Any required aviation authority approval must also be obtained; operator approval does not replace it. Purchase, download or acceptance of these terms is not operational approval.

06Updates and termination

The Google Play offer states supported systems and requirements. Network features need a connection. Statutory and agreed updates and defect remedies are covered by the Terms of Use. You can terminate by stopping use and removing your copies; subscriptions must be cancelled separately in the store. A material breach may lead to proportionate termination after notice and an opportunity to remedy a remediable breach. Statutory claims and necessary access to your own data survive.

07Applicable law and liability

Czech law governs the contract with SilkIdea. Consumers retain the protection of mandatory rules in their country of habitual residence where applicable and all legally protected court jurisdiction. Mandatory local guarantees, remedies and deadlines in other countries remain intact; for example, these terms do not exclude Australian statutory consumer guarantees.

We do not exclude liability that cannot lawfully be excluded, including for intent, gross negligence, harm to protected personal rights or mandatory consumer claims. Technical limitations do not remove remedies for defective supply. These terms impose no mandatory arbitration or waiver of class actions or other legal remedies.

08Language versions

We prepare these documents in Czech and provide translations. If language versions of the same document and the same version conflict, the Czech text prevails to the extent permitted by applicable law. This does not affect mandatory local language requirements, mandatory consumer rights, interpretation of ambiguities in the consumer’s favour or information reasonably relied on when concluding the contract. This clause does not give priority between different dated versions and does not override the separate Apple Standard EULA or Joinly documents.
