Covered Services

This Privacy Policy covers the following Services:

If a product, app, or service is not listed above, this Privacy Policy applies only if it links to this Privacy Policy and is published by NEXT AI Lab or operated by Sophon LLC.

This Privacy Policy explains how we access, collect, use, disclose, and protect information when you access a website, download or use a mobile app, or otherwise use the Services. It is intended to be read together with any in-app permission prompts, web notices, app store privacy disclosures, and platform-specific privacy information.

If you do not agree with this Privacy Policy, please do not use the Services.

1. Information We Collect

The exact information collected depends on the specific product, platform, app version, device settings, region, and features you use. Some Services may process files locally on your device and may collect little or no personal information. Other Services may include accounts, document upload, AI document understanding, summaries, notes, slides, podcast or audio generation, ads, analytics, subscriptions, crash reporting, cloud import/export, or online features.

1.1 App activity and usage data

We may collect information about how you interact with the Services, such as feature usage, app launches, session information, diagnostic events, document processing events, generation events, subscription-related events, ad interaction events, and performance data. We use this information to operate, maintain, analyze, and improve the Services.

1.2 Device identifiers and advertising identifiers

The Services may use device identifiers, including advertising identifiers such as Google Advertising ID or IDFA, where permitted by your device settings and applicable law. These identifiers may be used for analytics, attribution, fraud prevention, app performance measurement, and advertising.

1.3 Camera, photos, documents, files, prompts, and generated content

The Services provide document scanning, PDF reading, PDF editing, document viewing, file conversion, OCR, signing, annotation, AI document understanding, summaries, notes, slides, podcast or audio generation, file import, file export, and related document features. To provide these features, the Services may request access to your camera, photos, media, documents, or file storage, and may process files, prompts, instructions, transcripts, audio, generated outputs, and related metadata.

We use this information only to provide the features you choose to use, such as scanning documents, importing files, viewing documents, creating PDFs, editing files, converting files, exporting files, saving files on your device, chatting with documents, generating summaries, creating notes or slides, or generating podcast/audio content. Unless a feature clearly requires upload, cloud access, account synchronization, or AI processing, your documents and files remain on your device or with the storage provider you select.

1.4 Account, purchase, and subscription information

If a Service offers account, purchase, or subscription features, we may process information needed to provide those features, such as account identifiers, email address, purchase status, subscription status, transaction identifiers, receipts, plan information, and related support information. Payments and subscriptions may be processed by Google Play, Apple, Stripe, or other third-party payment providers, and their processing is governed by their own terms and policies.

1.5 Crash, diagnostics, and performance data

We may collect crash reports, diagnostics, logs, device information, operating system information, app version, and other technical data to identify and fix bugs, reduce crashes, improve performance, and maintain security.

1.6 Approximate location

Some third-party analytics, advertising, attribution, or infrastructure services may infer approximate location from network or device information, subject to your device settings and applicable law. We use this information for analytics, advertising, security, localization, and service improvement.

2. Permissions Used by the Services

Depending on the product, platform, and features you use, the Services may request permissions such as:

• Microphone or audio access, if a version supports voice input, recording, playback, podcast, or other audio-related features.
• Notification permission, if a Service provides notices, reminders, account updates, service messages, or promotional messages.
• Internet access, so a Service can provide online features, account sync, AI processing, analytics, advertising, purchase validation, crash reporting, cloud import/export, and service updates.

We request permissions when they are needed for functionality. You can manage permissions in your device or browser settings. Some features may not work if you deny or revoke a required permission.

These services may collect information such as device identifiers, advertising identifiers, app activity, web activity, ad interactions, crash data, diagnostics, approximate location, and usage data according to their own privacy policies.

5. Cloud Storage and Third-Party File Providers

If you choose to connect or import files from third-party storage providers, such as Google Drive, Dropbox, OneDrive, or similar services, the relevant Service accesses the files only as needed to provide the feature you request. We do not sell your cloud files. Files may remain on your device or with the third-party provider unless you choose to upload, export, share, analyze, summarize, generate, or otherwise process them through a feature that requires transfer.

Our use and transfer of information received from Google APIs will comply with the Google API Services User Data Policy, including the Limited Use requirements.

6. AI Processing and Generated Content

Some Services, including PDF AI, may use automated systems, machine learning models, speech processing, text processing, file parsing, and other service providers to process your inputs and generate outputs. We may share content and related metadata with service providers only as needed to provide, secure, maintain, and improve the Services, subject to applicable contractual and legal safeguards.

Generated outputs may be incomplete, inaccurate, or unsuitable for your intended use. You are responsible for reviewing outputs before relying on them.

• To protect the rights, property, security, or safety of users, the Services, Sophon LLC, NEXT AI Lab, or others.
