By accessing or using this website (https://umbrabyte.app) or downloading applications published by Umbrabyte Apps, you agree to be bound by these Terms of Use and our Privacy Policy. If you do not agree, please discontinue use immediately.
1. Studio identity & legal capacity
Umbrabyte Apps operates as a registered sole proprietorship (profesional autónomo) under the laws of the Kingdom of Spain and the European Union, specializing in native mobile software engineering and digital interface design.
2. Intellectual property & license
Unless otherwise indicated, all content on this website and in our applications—including but not limited to source code, user interface designs, visual layouts, icons, typography, trademarks, logos, texts, documentation, and media assets—is the exclusive intellectual property of Cristian Donet Segura and is protected by Spanish, European, and international copyright and industrial property laws.
- Grant of License: When you download an application from an official app store (e.g. Google Play Store), you are granted a personal, non-exclusive, non-transferable, revocable license to use the software on your compatible device for personal or internal business purposes in accordance with these terms.
- Restrictions: You may not copy, modify, distribute, sell, sublicense, reverse-engineer, decompile, or extract source code from our software or website content without prior express written authorization.
3. Acceptable use policy
You agree to use this website and our applications strictly for lawful purposes. You must not:
- Attempt to interfere with, damage, disrupt, or gain unauthorized access to our servers, networks, or connected infrastructure.
- Use automated scrapers, crawlers, bots, or extraction scripts in a manner that imposes an unreasonable burden on our hosting infrastructure.
- Transmit malware, viruses, worms, or malicious code.
- Misrepresent your affiliation with Umbrabyte Apps or forge headers/identifiers.
- Use our applications in violation of applicable local, national, or international laws.
4. In-app purchases, lifetime products, subscriptions & billing terms
Our applications may offer optional premium features, one-time lifetime purchases, or auto-renewing subscriptions (such as PRO tiers):
- Storefront Governance: All payments, currency conversions, applicable sales taxes (VAT/GST), and digital receipts are processed directly by the official app storefront operator (Google Play Store operated by Google LLC / Google Ireland Limited). Umbrabyte Apps never receives, accesses, or stores credit card numbers or financial credentials.
- One-Time Lifetime Purchases (Lifetime Access): Certain applications (such as Speaker Cleaner: Water & Dust with `speakercleaner_pro_lifetime`) provide optional permanent access via a single, non-recurring, one-time payment. Lifetime purchases grant permanent entitlement bound to your Google Play account across all compatible devices without recurring fees, periodic renewals, or subscription charges.
- Auto-Renewing Subscriptions: Where an application offers subscription tiers (e.g. monthly or yearly plans), subscriptions automatically renew at the end of each billing cycle unless cancelled at least 24 hours prior to the renewal date.
- Cancellation: You may cancel or manage subscriptions at any time directly within your Google Play Store account settings (Google Play > Payments & subscriptions). Cancellation takes effect at the end of the current paid billing period.
- Refunds: All refund requests are governed exclusively by the official Google Play Refund Policy.
- Core Free Guarantee & Daily Quotas: Core offline features of our applications remain accessible without requiring ongoing purchases, including daily renewable free quotas (such as 3 daily free cleanings in Speaker Cleaner).
5. Disclaimer of warranties & acoustic utility notice
This website, its content, and all applications are provided on an “AS IS” and “AS AVAILABLE” basis, without warranties of any kind, whether express, statutory, or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, or uninterrupted operation.
While we strive for technical excellence, we do not warrant that our software will be completely error-free, uninterrupted, or compatible with every hardware and operating system configuration.
Acoustic & Hardware Utility Disclaimer: Certain applications (including Speaker Cleaner: Water & Dust) emit mathematically calibrated sound waves, resonance frequencies (such as 165 Hz sweeps), and mechanical vibration pulses designed to assist in dislodging physical water droplets and dust particles from phone speakers and earphone diaphragms. You understand and acknowledge that:
- (a) Acoustic vibration is a mechanical maintenance tool and does not guarantee hardware repair in instances of permanent membrane tears, liquid chemical corrosion, water-induced electrical short-circuits, or blown voice coils;
- (b) High-volume cleaning cycles emit elevated sound pressure; you must follow in-app acoustic safety recommendations and keep the device speaker pointed away from ears during active ejection cycles;
- (c) The software does not replace certified professional hardware repair services if your device has sustained structural hardware failure.
6. Limitation of liability
To the maximum extent permitted by applicable law, in no event shall Cristian Donet Segura (Umbrabyte Apps) be liable for any indirect, incidental, special, consequential, or punitive damages—including loss of profits, loss of data, loss of business goodwill, work stoppage, or device malfunction—arising out of or in connection with your use of or inability to use the website, applications, or services.
Statutory Exclusions: Nothing in these terms excludes or limits liability for death or personal injury resulting from negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited under mandatory consumer protection laws of your jurisdiction.
7. Consumer protection & right of withdrawal (EU / Spain)
If you are a consumer residing within the European Union, you benefit from statutory consumer protections under Directive 2011/83/EU and the Spanish Royal Legislative Decree 1/2007 (TRLGDCU).
In accordance with EU consumer rules for digital content, when you purchase in-app digital content or subscriptions through Google Play and consent to immediate performance, you acknowledge that your statutory 14-day right of withdrawal may expire upon the commencement of digital delivery, as governed by Google Play Store terms.
8. Alternative dispute resolution (EU ODR)
In compliance with EU Regulation No 524/2013, the European Commission provides an Online Dispute Resolution (ODR) platform for consumer disputes. EU consumers may access the platform at:
https://ec.europa.eu/consumers/odr
Our official contact email for dispute resolution is: support@umbrabyte.app.
9. Governing law and jurisdiction
These terms and any disputes arising from or related to them shall be governed by and construed in accordance with the laws of the Kingdom of Spain, without regard to conflict of law principles.
Any dispute that cannot be resolved amicably shall be submitted to the exclusive jurisdiction of the Courts of Castellón de la Plana, Spain, without prejudice to any mandatory statutory forum rights granted to consumers under applicable consumer protection legislation.
