Privacy Policy

Last Updated: April 23, 2026 Version: 1.2

INX Company Limited (“we”, “our”, “us”) operates the NearbiJSX application. This Privacy Policy explains how we collect, use, and protect your information when you use our app.

NearbiJSX is a local-first application for running and managing Claude-generated JSX artifacts. We do not operate any servers that receive your personal information, and we do not run first-party analytics or crash reporting SDKs. On iOS and iPadOS, the free tier of the app displays advertisements through third-party ad networks, as described below.

Information We Collect

Advertising Identifiers and Ad Network Data

On iOS and iPadOS, the free tier of our app displays advertisements through Google AdMob and Unity Ads. The macOS version does not include any advertising SDKs.
Before any ad-related data is collected, the app asks for your permission through Apple’s App Tracking Transparency (ATT) prompt. The ATT request is issued at app launch, before the AdMob and Unity Ads SDKs are initialized. You can deny or restrict this request at any time.
When you grant ATT authorization, the ad networks may collect and process the following data categories, associated with your advertising identifier, for third-party advertising purposes:
- Device ID — Apple Advertising Identifier (IDFA) used to deliver and measure personalized ads.
- Product Interaction — tap timing, ad-request timing, ad impression / dismiss events inside the app, used for frequency capping and targeting.
- Advertising Data — which ads were shown, which were clicked, viewability metrics, used for reporting and billing.
Regardless of ATT state, the ad SDKs also collect the following technical telemetry, not used for advertising targeting and not linked to your identity:
- Crash Data — SDK-level crash logs, used only to diagnose and fix issues in the ad SDK.
- Performance Data — runtime metrics such as execution time, hang rate, and energy usage, used only to improve SDK performance.
If you deny or restrict tracking, ads still serve via Apple’s SKAdNetwork for privacy-preserving attribution, without identifying you personally.
NearbiJSX Pro (in-app purchase) removes all advertisements and therefore all ad-network data collection described above.

Location Data

We access your approximate location only to provide weather-aware greetings on the home screen.
Your approximate location is sent to Apple Weather (WeatherKit) to retrieve current weather conditions. This data is handled by Apple under Apple’s Privacy Policy. We do not receive, store, or forward your location data to any other party.
Weather data is provided by Apple Weather. See Apple Weather attribution for details.
On iOS/iPadOS, location is requested only while using the app. On macOS, the app may request persistent location access to provide weather greetings.
You can deny location access at any time in your device settings. The app works fully without it.

iCloud Data

JSX files you create are stored in your personal iCloud container (iCloud.com.nearbijsx) if you choose iCloud storage.
This data is managed entirely by Apple’s iCloud service. We do not have access to your iCloud data.

AI API Keys and Prompts

If you use the AI assistance feature, you provide your own API keys (Claude, OpenAI, Gemini, GitHub Models).
API keys are stored locally in your device’s Keychain. They are never transmitted to our servers.
API requests are sent directly from your device to the respective AI provider.
Important: The content of your prompts (JSX code and instructions you send to the AI) is transmitted to the AI provider you select. Each provider applies its own data handling policy, which may include temporary retention for abuse prevention, safety review, or model improvement. For example, Anthropic may retain prompt data for up to 30 days and, depending on your account settings with Anthropic, may use prompts to improve their models. Review the provider’s privacy policy (linked in the “Third-Party Services” section below) before sending sensitive or confidential content through the AI feature.

Information We Do NOT Collect

We do not collect personal information such as name, email, phone number, or address.
We do not use any first-party analytics or crash reporting SDKs.
We do not have user accounts or login systems.
We do not operate any servers that receive your data.

Legal Basis for Processing

Under the EU General Data Protection Regulation (GDPR) and the Korean Personal Information Protection Act (PIPA), we rely on the following legal bases for any limited processing that occurs:

Consent — Location access for weather greetings, App Tracking Transparency (IDFA) for personalized advertising, and use of the optional AI assistance feature. You may withdraw consent at any time through device settings or by not using the feature.
Performance of contract — Processing necessary to deliver the app you purchased (e.g., in-app purchase verification via Apple StoreKit).
Legitimate interests — Ensuring the security and integrity of the app (e.g., Keychain storage of sensitive credentials), and serving non-personalized advertising to free users on iOS/iPadOS.

Data Retention

JSX files, settings, and preferences are retained on your device (and, if you opt-in, your personal iCloud container) until you delete them. We have no ability to delete or access this data on our end.
App deletion preserves the local Documents/NearbiJSX/ folder until you manually remove it, so your JSX files are not lost if you reinstall the app.
Location data is processed in memory for a single weather request and is not persisted by the app.
AI prompts are transmitted directly to the AI provider you selected and are not logged, stored, or retained by us.
Weather data is cached on-device for up to 30 minutes to reduce redundant API calls.

NearbiJSX supports sharing JSX files with nearby devices over the local network using Apple’s MultipeerConnectivity framework.
The app requests Local Network permission to discover and connect with nearby devices.
All communication happens directly between nearby devices. File data shared during this process is not routed through any external server.
Apple’s MultipeerConnectivity framework provides TLS-based transport security between peers by default.

In-App Purchases

Purchase transactions (NearbiJSX Pro) are processed entirely by Apple’s App Store. We do not collect or store any payment information.
Pro users do not see advertisements.

File Access

NearbiJSX enables file sharing with your computer via the Finder (macOS) or the Files app (iOS/iPadOS). Files stored in the app’s Documents folder are accessible through these system tools.

Data Storage and Security

All JSX files, settings, and preferences are stored locally on your device or in your personal iCloud container.
No data is stored on our servers.
API keys (Claude, OpenAI, Gemini, GitHub Models) are stored in the Apple Keychain, which is protected by device-level encryption.
Network transport to AI providers and ad networks uses HTTPS (TLS 1.2+).
iCloud data is encrypted in transit and at rest by Apple. See Apple’s iCloud security overview.

Third-Party Services (Subprocessors)

Because NearbiJSX does not operate its own servers, all network activity flows directly from your device to the third-party services you choose to use or that the free tier requires. The following services may receive data from your device when you use the corresponding feature:

Service	Provider	Purpose	Data Transferred	When
Google AdMob	Google LLC (USA)	Advertising (iOS/iPadOS only)	IDFA (if ATT granted), device info, product interaction, advertising data, SDK crash and performance telemetry	Free-tier users on iOS/iPadOS
Unity Ads	Unity Technologies ApS (Denmark / USA)	Advertising (iOS/iPadOS only)	IDFA (if ATT granted), device info, product interaction, advertising data, SDK crash and performance telemetry	Free-tier users on iOS/iPadOS
Apple WeatherKit	Apple Inc. (USA)	Weather greetings	Coarse location (reduced accuracy)	Only when location permission is granted
Apple iCloud	Apple Inc. (USA)	Optional JSX file sync	JSX files you create	Only if you enable iCloud storage
Apple App Store / StoreKit	Apple Inc. (USA)	In-app purchase processing	Anonymized transaction IDs	When you purchase NearbiJSX Pro
Anthropic Claude	Anthropic PBC (USA)	AI assistance	Your prompt text	Only when you invoke the AI feature with a Claude key
OpenAI	OpenAI OpCo, LLC (USA)	AI assistance	Your prompt text	Only when you invoke the AI feature with an OpenAI key
Google Gemini	Google LLC (USA)	AI assistance	Your prompt text	Only when you invoke the AI feature with a Gemini key
GitHub Models	Microsoft Corporation (USA)	AI assistance	Your prompt text	Only when you invoke the AI feature with a GitHub token

Each provider has its own privacy policy governing how it handles data it receives:

International Data Transfers

NearbiJSX is distributed worldwide. When you use the features listed in the Third-Party Services table above, data may be transferred to the United States and other jurisdictions where those providers operate their infrastructure. By enabling the corresponding feature (location, iCloud, AI assistance, personalized ads), you acknowledge that the relevant data is transferred to the selected provider outside your country of residence.

We do not transfer your data to any party other than those third-party services that you have actively chosen to use or that the free tier of the app requires for ad delivery.

Your Rights

Depending on your jurisdiction (EU/UK under GDPR, California under CCPA/CPRA, Korea under PIPA), you may have the following rights regarding your personal information:

Access — Request a copy of the information we hold about you. (Because we store nothing on our servers, this is effectively achieved by browsing the app’s files and settings on your device.)
Rectification — Correct inaccurate information. You can edit all in-app data directly.
Erasure — Delete your information. You can delete files, clear app storage, or uninstall the app to remove all local data.
Portability — Obtain your data in a portable format. The app lets you export JSX files directly.
Withdraw consent — Revoke permissions (location, Local Network, App Tracking) in your device settings at any time.
Object / restrict processing — Contact us at cs@i-nx.com.
Lodge a complaint — You may contact your local data protection authority. In Korea, that is the Personal Information Protection Commission (pipc.go.kr).

Because NearbiJSX operates without user accounts or servers, most rights are exercised directly on your device.

Automated Decision-Making

NearbiJSX does not engage in automated decision-making, profiling, or any processing that produces legal or similarly significant effects on users. The AI assistance feature, when enabled, produces code and text suggestions for your JSX artifacts; it does not make decisions about you or assign you to any category.

Privacy Manifest and App Store Privacy Details

NearbiJSX includes an Apple Privacy Manifest (PrivacyInfo.xcprivacy) and declares the following data in App Store Connect’s “App Privacy” section:

Data Type	Purpose	Linked to You	Used to Track You
Identifiers — Device ID (IDFA)	Third-Party Advertising	Yes	Yes
Location — Coarse Location	App Functionality (weather greeting)	No	No
Usage Data — Product Interaction	Third-Party Advertising	Yes	Yes
Usage Data — Advertising Data	Third-Party Advertising	Yes	Yes
Diagnostics — Crash Data	App Functionality	No	No
Diagnostics — Performance Data	App Functionality	No	No

Additional manifest details:

Tracking domains: Ad-related domains used by Google AdMob and Unity Ads for ad delivery.
Accessed APIs: UserDefaults, file timestamps, and disk space — used solely for normal app operation.
Location is handled entirely client-side, passed only to Apple WeatherKit, and never linked to your identity or shared with third parties.

Children’s Privacy

NearbiJSX does not knowingly collect any personal information from children under the age of 14 (Korean standard) or 13 (US COPPA standard) / 16 (EU GDPR standard, depending on member state). If you believe a child has provided information through our app, please contact us and we will assist where possible.

Open Source Attribution

NearbiJSX is built on open source software. The JSX rendering engine bundles (non-exhaustive): React 18, react-runner, Sucrase, Tailwind CSS, shadcn/ui, Lucide React, Recharts, Lodash, D3.js, Three.js, Papaparse, SheetJS, and MathJS. Full license notices are available in the app under Settings → About → Open Source Licenses.
