Terms of Use

01Provider 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.

02Use and accuracy

PROtune processes microphone audio on the device for tuning and recognising notes and chords. These features need your microphone permission. Noise, simultaneous notes, microphone quality, reference frequency and tuning settings may affect results. It is a musical aid, not a calibrated measuring instrument. You may use it personally or professionally while respecting music rights and other people’s privacy.

Compatible devices, operating systems and available features are described in the App Store and in-app offer. Trial mode or free features do not themselves create a subscription. A purchase requires confirmation of the relevant store offer.

03Purchases and subscriptions

The offer shown before purchase specifies the price including applicable taxes, currency, unlocked features and access period. Subscriptions renew automatically unless cancelled under store rules in your Apple account settings. Uninstalling does not cancel a subscription. Cancellation usually stops the next renewal while access continues through the paid period; mandatory rights to earlier termination and refunds remain unaffected.

A one-off unlock or “lifetime” offer is not a recurring subscription. It gives access to the features described in the offer without a recurring fee, rather than promising all future separate products. This does not shorten the promised supply period, statutory updates or remedies if we stop supplying paid features. Purchase restoration depends on the store account and purchase type.

04Withdrawal from a purchase

EU/EEA consumers generally have 14 days from concluding a distance contract to withdraw without giving a reason. For paid digital content supplied without a physical medium, the right ends when supply starts only if the legal conditions are met: prior express consent to supply during that period, acknowledgement of losing the right, and the required contractual confirmation. Reading these terms or buying the app is not such consent for every future service.

For a service started during the withdrawal period at your express request, a proportionate charge for what was actually supplied may be due. Full performance ends the right only when the legal conditions are satisfied. If an exception does not apply, the right remains. Valid withdrawal refunds are made within the statutory period, generally 14 days, using the original payment method unless another cost-free method is agreed.

For a store purchase, you may also use its refund process: Apple https://reportaproblem.apple.com/. Claims against SilkIdea can be made directly to us. Optional notice template: “To SilkIdea s.r.o., info@silkidea.com. I withdraw from the contract for [app/service and order reference], concluded on [date]. Consumer name and address: […]. Date: […].” A signature is needed only for a paper notice.

05Defects, complaints and disputes

Send complaints to info@silkidea.com or our registered office, identifying the app, problem, requested remedy and any available purchase receipt or job reference. We confirm receipt and the outcome. We remedy defects in digital services free of charge within a reasonable time and without significant inconvenience. Where a remedy is impossible, refused, unsuccessful or the defect is serious, statutory conditions may entitle you to a price reduction or termination and the corresponding refund.

For Czech consumers, defects becoming apparent within two years of a one-off digital supply are covered; continuous services are covered throughout their supply period. Digital-content complaints must be resolved within a time reasonable for the nature and purpose of the service; any shorter mandatory deadline remains applicable. We provide agreed and legally required updates, including security updates, and installation information.

An unresolved consumer dispute with SilkIdea can be referred to the Czech Trade Inspection Authority: https://coi.gov.cz/informace-o-adr/. An application can generally be filed within one year after first raising the claim with us. For EU cross-border disputes, assistance is available at https://evropskyspotrebitel.cz/. Your right to approach a court or another competent body remains unaffected.

06Applicable 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.

07Changes and termination

We may change the service for security, legal compliance, operating-system compatibility or availability of an essential supplier. Changes to a continuous service must meet applicable statutory conditions, carry no additional cost for that change and be clearly notified. We give advance notice on a durable medium of adverse changes that are more than minor, including the right to terminate. Under Czech rules that right can be exercised within 30 days of notice or implementation, whichever is later, unless the unchanged service remains available in conformity and at no extra cost.

New terms or prices do not automatically apply retrospectively to confirmed orders. Access restrictions for misuse must be proportionate; where circumstances permit, we explain the reason and remedy. If the service ends, we settle outstanding orders, paid supplies that can no longer be used and statutory claims. These provisions do not permit arbitrary removal of a paid service.

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.
