Privacy Policy
Effective date: September 11, 2026
Responsible company: NextPhase LLC
Privacy contact: support@nextphaseapps.com
This policy explains how NextPhase LLC (“NextPhase”, “we” or “us”) handles information when you visit this website, use NextPhase Reader, or contact us for help. App features differ by platform and version. The information involved depends on the features you choose to use.
At a glance
- Your reading starts on your device. The installed app keeps a local library, reading progress, saved vocabulary and settings.
- Online features involve online services. Translation, online voices, catalogs and optional account or sync features can send information outside your device.
- The website demo uses prepared content. It does not upload your books or send your selections to a live translation or speech service.
- You control what you send for support. Please do not include passwords, API keys or private book content in a support message.
1. Visiting this website
The website and downloadable files are delivered through Cloudflare. Delivering and protecting those services involves technical information such as your IP address, browser information, requested pages or files, request times and response status. Hosting and security services may process or retain this information for operation, troubleshooting and abuse prevention. See Cloudflare’s privacy policy for its practices.
The current website does not include advertising trackers or product-demo analytics instrumentation. Hosting request logs are separate from those tools. We will update this notice if we introduce additional collection.
Preferences and interactive samples
The website stores your Light or Dark theme preference in your browser’s local storage. You can remove it by clearing this site’s stored data in your browser settings.
Reading samples, translations, export previews and narration are prepared examples. Sample word saves and interactive reading state stay in the page’s memory and reset when you reload. The demo does not create an account, upload files, access your microphone or generate speech using your input.
PDF pages, audio recordings, fonts and other sample assets are requested from this website as needed. Playing a prepared recording does not send the story text to a speech provider at playback time. Your browser may cache these files.
Links to app stores, catalogs and other websites take you to services with their own privacy practices.
2. Reading in the installed app
Reader stores information on your device to make reading and learning work. Depending on your platform and use, this includes:
- imported books, document text, covers and library organization;
- reading positions, preferences and reading statistics;
- cached translations;
- saved words, sentence context and review activity;
- downloaded language or voice resources and rendered audio.
Local storage does not mean that every feature operates offline. Online features described below make network requests, including when you use the app without an account. Your operating system’s backup or device-sync services may also handle app data under their own settings and policies.
Export anything you want to keep before uninstalling or clearing app data. Removal behavior varies by operating system and installation method; uninstalling is not a request to delete an online account.
3. Accounts and optional sync
Where available, account and sync services use Supabase. Signing in can involve your email address, account identifier, authentication information and profile information supplied by your sign-in provider, such as a name or avatar. These services also process technical information needed to operate and secure sign-in.
When you enable supported sync features, information needed for those features can be stored online. This can include library records, book files and covers, translations, vocabulary and review activity, reading positions and statistics. Availability and sync coverage differ by platform and version.
Turning off sync stops further syncing through that feature. It does not, by itself, erase information already stored online or copies held on other devices. Signing out is also different from deleting an account.
4. Translation, voices and connected libraries
| Feature you use | Information involved |
|---|---|
| Online translation | Text submitted for translation, language choices, provider settings and information needed to authenticate and deliver the request |
| Online read-aloud | Text to be spoken, selected language or voice, and technical request information |
| On-device translation or voices | Text is processed locally for that operation; downloading models, voice packs or updates still requires a network request |
| Public catalogs | Searches, requested records, covers, availability checks and book downloads |
| A connected OPDS library | Requests and any authentication information needed by the library server you configure |
The destination depends on the engine or service you select. Examples include Google or Microsoft translation and speech services, other configured providers, public book catalogs, and your own library server. Some hosted features route requests through a NextPhase service before reaching the provider. Provider retention and other processing practices depend on the service and account you use; local processing should not be assumed for an online engine.
If you want text processed on your device, choose a supported on-device engine and check its availability for your language and platform. Translation quality, model downloads and feature availability are separate from privacy settings.
Provider keys and credentials
Credential handling differs by platform. Desktop provider keys use the operating system’s credential store and are used when making the selected provider’s requests. Hosted web functionality can use server-side secret storage. Authentication and library credentials are handled by the relevant platform or service.
Do not include keys or credentials in screenshots or support messages. Removing a saved provider key from Reader does not revoke that key at its provider; use the provider’s controls when you need to revoke it.
5. Exports, sharing and support
When you export or share content, the file or information you choose is passed to the destination you select. A bilingual book, vocabulary file, rendered audio or screenshot may contain book text, translations, personal notes or learning history. Check the contents and destination before sharing. Copies you export are outside Reader’s control.
If you contact support, we receive your message, reply address and any details or attachments you choose to send. We use them to answer your request, investigate the problem and maintain the service. Email and support infrastructure process these communications as part of delivery and storage.
Start with the app version, platform and a description of the problem. A redacted screenshot or a short non-sensitive example is usually more useful than an entire book. See Support for guidance.
6. How information is used and disclosed
We use information to provide requested features, maintain accounts and services, respond to support requests, investigate failures and protect against misuse. Service providers handle information needed to perform those functions, including hosting, authentication, sync, selected translation or speech services, and communications.
We do not sell your personal information or use your reading content for targeted advertising. Using a third-party feature still involves the disclosures described above. We may also disclose information when required by applicable law or when reasonably necessary to protect the security, rights or safety of users and our services.
7. Storage, retention and security
Local information remains subject to your device’s storage, deletion and backup settings. Online account information, synced content, support messages and operational records have different storage and retention needs. We retain information as needed for its stated purpose and applicable obligations. Deletion may take time to reach connected devices, service systems and backups; it should not be understood as immediate removal of every copy.
We use platform credential storage and service access controls to protect information. No method of storage or transmission is completely secure. Keep your device and account secure, and share only what is needed when asking for help.
Service providers may process information in countries other than where you live. The services involved depend on your settings and the features you use.
8. Your choices and privacy requests
You can manage local books and saved words, choose supported on-device processing, remove saved provider settings, and control available sync options. Export options vary by source format and platform.
For account deletion or a request to access, correct, export or delete information we hold, email support@nextphaseapps.com. We may need to verify that the request relates to you. We will handle requests in accordance with applicable law, including any permitted exceptions.
Depending on where you live, you may have additional rights, such as restricting or objecting to certain processing, withdrawing consent where processing relies on it, or contacting a relevant privacy regulator. A request to NextPhase does not automatically delete information held independently by a translation provider, app store or other service.
If you believe a child has provided personal information to us, contact us so we can review the situation and take appropriate action.
9. Changes and contact
We will update this page and its effective date when our practices change. Where required, we will provide additional notice or obtain consent before a change takes effect. Future features are not covered by a blanket permission to collect additional information.
Questions about privacy can be sent to the contact listed at the top of this page. For reading, installation or technical help, visit Support.
