The Full Picture, Clearly Told

Comprehensive, structured, and authoritative clarity.

"Black holes changed the meaning of thermodynamics. In classical general relativity, the total area of event horizons tends to increase under ordinary conditions. Jacob Bekenstein proposed that this area could represent entropy, a measure of hidden microscopic information. Stephen Hawking then showed that quantum fields near a horizon give a black hole a temperature and allow it to radiate.

The puzzle is that Hawking radiation appears thermal, carrying a limited description of the object that produced it. Quantum mechanics normally preserves information about a physical system as it evolves. If a black hole disappears into purely thermal radiation, information about everything that fell in seems to be lost. General relativity and quantum theory then offer answers that do not fit together cleanly."

This policy explains how Wikivox handles information when you use our mobile app, website, and support channels.

1. Scope

Wikivox ("Wikivox," "we," "us," or "our") provides an audio knowledge app and the wikivox.app website. This policy applies to people using Wikivox in the United States, Canada, and Australia.

The app does not require an account. We still process limited technical, usage, purchase, and diagnostic information to operate and improve the service.

2. Information we process

App and device information: We process app installation identifiers, app version, device and operating system details, language, time zone, network information, IP address, and push notification tokens. These identifiers are not your name or email address, but they can distinguish an app installation or device.

Usage and listening information: We process interactions such as screens viewed, selected titles and categories, listening editions, playback activity, download actions, onboarding progress, library actions, settings, and subscription state. Search terms are sent to the Wikivox service to return search results. Our analytics events record search length and result counts, not the text of a search query.

Purchases and subscriptions: Apple, Google, and RevenueCat process information needed to manage trials, purchases, renewals, restores, and subscription access. We may receive the purchased product, subscription status, expiration date, store receipt or purchase token, and an anonymous customer identifier. We do not receive your full payment card details.

Diagnostics and performance: We process crash reports, stack traces, app state, device and OS information, app start time, network latency, CPU and memory metrics, and related diagnostics. This helps us investigate failures and improve reliability.

Communications: If you contact us, we process the information you provide, including your email address, message, and any technical details you choose to include.

3. Information stored on your device

Saved titles, playlists, playback progress, preferences, and downloaded audio are primarily stored on your device. Wikivox does not currently provide an account that synchronizes this library to other devices. Deleting the app or clearing its storage may remove this local information.

4. How we use information

We rely on your consent where required. We also process information when needed to provide the service you request, comply with law, and pursue legitimate interests such as security, diagnostics, and product improvement, where those interests are permitted by law.

5. Service providers and disclosures

We use service providers that process information for us:

We may also disclose information when required by law, to protect people or the service, or as part of a business transaction subject to appropriate safeguards.

We require service providers to protect information consistently with this policy and applicable law.

Wikivox does not sell personal information, display third-party ads, or use app information for cross-app behavioral advertising.

6. Retention

Local app information remains on your device until you remove it or delete the app. We retain installation and entitlement records while needed to provide access, prevent abuse, and resolve purchase issues. Purchase records may be kept longer when required by store, tax, or legal obligations.

Analytics and diagnostic information follows the retention settings of our Firebase services and is deleted or aggregated when it is no longer needed. Support communications are retained until the request is resolved and any reasonable recordkeeping period has ended.

7. International processing

Our service providers may process information outside your state, province, territory, or country, including in the United States. Privacy protections may differ in those locations. We use contractual and other safeguards required by applicable law.

8. Your choices and rights

Contact us to make a privacy request. We may need an installation or RevenueCat customer identifier to locate information that is not connected to your name or email address. We may retain information where required by law or needed to protect the service.

9. Regional privacy rights

Residents of certain US states may have rights to know, correct, delete, or obtain a copy of personal information. Wikivox does not sell personal information or share it for cross-context behavioral advertising.

Canadian users may request access or correction and may withdraw consent subject to legal limits. Australian users may request access or correction and may raise a privacy complaint. If you are not satisfied with our response, you may contact the privacy regulator that applies where you live.

10. Children

Wikivox is not directed to children under 13. We do not knowingly collect personal information from a child who cannot legally consent without a parent or guardian. Contact us if you believe a child has provided personal information so we can review and delete it where appropriate.

11. Security

We use reasonable technical and organizational measures designed to protect information, including encryption in transit and protected device storage for installation credentials. No system can guarantee absolute security.

12. Website

At the date of this policy, wikivox.app does not use analytics, advertising trackers, or non-essential cookies. If that changes, we will update this policy and provide any notice or choice required by law.

13. Changes to this policy

We may update this policy as Wikivox changes. We will post the new version here and revise the date above. We will provide additional notice when required by law.

14. Contact

Wikivox is currently offered through supported app stores in the United States, Canada, and Australia. Availability, catalogue content, features, prices, and platform support may differ by country, device, operating system, or store.

3. The service

Wikivox provides educational and informational audio content, catalogue discovery, search, playback, saved titles, playlists, and related features. Some titles or features may require Wikivox Premium.

Content is provided for general information and learning. It is not professional medical, legal, financial, safety, or other specialist advice. You should verify important information with appropriate primary sources or qualified professionals.

4. Premium subscriptions

Wikivox may offer monthly and annual auto-renewing subscriptions. Eligible users may receive a 7-day free trial. The store purchase screen shows the current price, currency, billing period, trial terms, and renewal date before you confirm a purchase.

Payment is charged to your Apple App Store or Google Play account. Unless you cancel before the renewal date shown by the store, your subscription renews automatically at the price displayed by the store. You can manage or cancel through your store account settings. Deleting Wikivox does not cancel a subscription.

Trial eligibility is determined by the store and may be limited to new or qualifying subscribers. When a trial ends, the paid subscription begins unless canceled. Refunds and billing disputes are handled under the store's rules and applicable consumer law. Restore Purchases is available in Wikivox settings.

5. Limited license

We grant you a personal, limited, non-exclusive, non-transferable, revocable license to use Wikivox for lawful, non-commercial purposes on devices you own or control, subject to these Terms and applicable store rules.

Wikivox, its software, design, branding, audio editions, and original content are owned by Wikivox or its licensors and are protected by intellectual property laws. Source material, names, images, and other third-party content remain the property of their respective owners.

Access to content is licensed, not sold. Offline downloads are for playback inside Wikivox and may expire or become unavailable when a subscription ends, rights change, or content is withdrawn.

7. Reports and feedback

You may report inaccurate, unlawful, or problematic content by contacting us. If you send suggestions or feedback, you allow us to use them without restriction or payment, while you retain ownership of any rights you already hold.

8. Third-party services

Wikivox depends on third-party platforms and service providers, including Apple, Google, Firebase, RevenueCat, hosting providers, and content delivery providers. Their own terms and privacy policies may apply to their services. We are not responsible for third-party services outside our control.

9. Changes and availability

We may update, add, limit, suspend, or remove features or catalogue content. We may also perform maintenance or respond to technical, security, legal, licensing, or store requirements. We do not guarantee that every feature or title will always be available.

10. Suspension and termination

We may restrict or end access if you materially violate these Terms, misuse the service, threaten security, or create legal risk. You may stop using Wikivox at any time. Ending use does not automatically cancel an active store subscription.

11. Disclaimers

To the extent permitted by law, Wikivox is provided "as is" and "as available." We do not guarantee uninterrupted operation, error-free content, complete accuracy, or permanent availability of any title.

Nothing in these Terms excludes warranties, guarantees, or other rights that cannot legally be excluded, including rights under the Australian Consumer Law and applicable US or Canadian consumer protection law.

12. Limitation of liability

To the extent permitted by law, Wikivox is not liable for indirect, incidental, special, consequential, or punitive loss arising from use of the service. Any limitation applies only to the extent allowed in your jurisdiction and does not limit liability that cannot legally be limited.

13. Applicable law

These Terms are governed by the laws that apply to the service and to you where you reside, without limiting mandatory consumer rights. You may bring a claim in any forum available to you under applicable law.

14. App store terms

Apple App Store or Google Play terms also apply when you download or purchase Wikivox through those platforms. If platform terms conflict with these Terms for store billing or distribution, the platform terms control for that issue.

15. Changes to these Terms

We may update these Terms as the service or law changes. We will post the revised Terms here and update the date above. Continued use after an update takes effect means you accept the revised Terms, where permitted by law.
