Privacy Policy

General Privacy Practices

BridgeAIWorks designs its apps with a privacy-conscious, local-first approach where practical. Many app features store user-created content on the user's own device by default. We do not sell personal information. We do not use advertising tracking. We process information only as needed to provide app functionality, support, safety, diagnostics, user-requested export or deletion, or features the user chooses to enable.

Depending on the app and enabled features, information may include learning content, handwritten input, practice answers, LINE identity information, trip Room information, location coordinates, meeting points, SOS events, documents, grading content, medication-related notes, images, OCR input, device diagnostics, app version, crash information, or support messages sent by the user.

If a specific BridgeAIWorks app provides additional in-app disclosures or a separate privacy notice, that app-specific notice applies to the relevant feature or app.

Nerd Dojo / 書呆子的練功房

Nerd Dojo is a learner-first native mobile and tablet app, not a SaaS learning platform. By default, learning data is stored locally on the user's device.

This may include handwritten work, practice answers, mistakes, review notebooks, learning progress, generated exercises, images, and study history. Unless the user enables a feature that requires external processing, BridgeAIWorks does not require this learning content to be uploaded to BridgeAIWorks servers.

If the user enables an AI provider, the app may send prompts, questions, answers, images, handwriting, or related learning context to the AI provider selected by the user. Provider processing is governed by that provider's terms and privacy practices.

API keys should not be stored in plain text. Nerd Dojo is designed to use secure platform storage such as Apple Keychain or Android Keystore when API keys are saved on-device.

Nerd Dojo does not use advertising tracking and does not sell personal information. Users may delete local learning data within the app where supported, by deleting app data from the operating system, or by uninstalling the app. Export features, where available, allow users to save their own learning records outside the app.

SafeMed / 安心藥盒

SafeMed, listed on the App Store as 安心藥盒, may involve health, medication, prescription, reminder, OCR, or medicine-safety-related information. Health and medication information can be sensitive, and users should avoid entering information they do not want processed by the app or by any provider they choose to enable.

SafeMed is designed with a conservative local-first approach unless a specific feature clearly requires external processing. If the user enables OCR, AI, cloud sync, backup, or a third-party provider, images, labels, medication names, notes, or related context may be transmitted to that provider for processing.

SafeMed is not an emergency medical service and is not a substitute for professional medical advice, diagnosis, treatment, pharmacy review, or emergency care. Users should consult qualified healthcare professionals for medical decisions and call local emergency services in an emergency.

SafeMed does not sell personal information.

Magic Travel Map / 魔法旅行地圖

This section covers the LINE LIFF web app only. For the native App Store app, see the MagicMap iOS / iPadOS Privacy Policy.

Magic Travel Map is currently a LINE LIFF travel group map at tour.bridgeaiworks.com. It helps guides create a trip Room, invite travelers by QR Code or LINE link, view member locations during the trip, set a meeting point, and receive in-app SOS events.

Magic Travel Map may process LINE identity information such as LINE user ID and display name, guide permission status, trial or subscription entitlement, organization information, Room ID, invite token, member nickname, member code, marker icon, selected sharing scope, meeting point details, location coordinates, location accuracy, timestamps, SOS events, LINE group binding information, and payment or trial records where applicable.

Location sharing is intended to be limited to the active trip Room and the user's selected visibility setting, such as guide-only visibility, all-room visibility, or selected-member visibility. Location information can reveal sensitive personal habits, routes, interests, and places a user may visit, so users should only join Rooms and share location with groups they trust.

In the current LIFF version, location updates depend on the user's device, browser, LINE in-app browser behavior, operating system permissions, network conditions, and whether the LIFF page remains active. The current LIFF product should not be described as continuous background tracking. Future native Mobile Pro versions may request background location permission only after separate app review, clear user consent, and in-app controls.

Active Rooms may expire automatically based on configured retention settings. The default Room lifecycle is designed for short trips, and ending or expiring a Room clears Room member records, member locations, SOS events, meeting settings, and active LINE group bindings for that Room. Recent displayed locations may also be filtered by freshness so stale locations are not treated as current.

If the user enables map, geocoding, payment, LINE Messaging API, cloud hosting, or future AI features, the app may send relevant Room, location, meeting point, payment, or message context to providers such as LINE, map/geocoding services, payment processors, Cloudflare, or future AI providers. Processing by those providers is governed by their own terms and privacy practices.

Magic Travel Map is not a safety-critical navigation, emergency rescue, medical, police, or travel-risk service. SOS is a group notification feature and is not a substitute for local emergency numbers, guide responsibility, traveler check-ins, travel insurance, or official safety procedures.

Magic Travel Map does not use advertising tracking and does not sell personal information.

AI Grader Pro

AI Grader Pro has its own product website at aigraderpro.com for product-specific marketing, downloads, licensing, documentation, support, and legal pages. This BridgeAIWorks Privacy Policy describes shared company-level practices that may apply when AI Grader Pro is identified as a BridgeAIWorks product or when BridgeAIWorks provides support for it.

AI Grader Pro may process documents, answers, rubrics, comments, grading criteria, scores, and feedback content. These materials may contain information provided by students, teachers, schools, or other users.

If the user enables an AI provider or cloud-based processing, documents, answers, grading content, prompts, and related context may be sent to the selected provider for analysis or generation. Users are responsible for ensuring they have the right to process and submit any student or third-party content.

BridgeAIWorks does not sell user documents, grading content, or student-provided content, and does not use such content for advertising tracking.

AI Grader Pro Special Edition (Mac App Store)

If this section conflicts with a general statement elsewhere in this Privacy Policy, this Special Edition section controls for AI Grader Pro Special Edition.

AI Grader Pro Special Edition is the Mac App Store edition published by BridgeAIWorks under bundle identifier com.bridgeaiworks.aigraderpro.specialedition. It is a local-first, single-teacher application. The developer does not operate a grading server for this edition and does not receive the teacher's student papers, rosters, rubrics, scores, grading history, or generated reports.

Student papers and images, class rosters, rubrics, grading results, corrections, reports, the local teacher profile, application logs, and caches are stored on the teacher's Mac in the app's sandbox container. A Google Gemini API key entered by the teacher is stored device-locally in macOS Keychain. A key entered by an earlier version may temporarily retain a local database migration-safety copy; neither copy is transmitted to BridgeAIWorks.

AI features use a bring-your-own-key workflow. When the teacher asks the app to generate questions or grade work, the relevant prompt, rubric, student answer, document image, and any student name or student ID visible in the submitted material are sent directly from the Mac to the Google Gemini API using the teacher's own API key and Google account. Google returns the generated questions, analysis, or grading response to the app, where the result is stored locally. BridgeAIWorks does not receive the submitted content, the generated response, or the API key.

Before each grading batch that includes student information, the app identifies Google as the third-party AI provider, displays the categories of information that will be sent, and requires the teacher's explicit authorization for that batch. Class analysis is a separate AI request and requires separate authorization for the student IDs, scores, grading comments, error evidence, and rubric used for that analysis. If the teacher does not authorize an operation, the app does not send that operation's content to Google; local viewing, editing, reporting, and other non-AI functions remain available.

Google processes submitted content under the teacher's applicable Google account and Gemini API terms and privacy commitments. When submitted material contains a student name, student ID, or other personal, sensitive, or confidential information, the teacher must use the Gemini API as a Paid Service through a Google Cloud project with active billing, unless Google's terms for the teacher's region expressly apply paid-service data treatment. Google's current terms state that Paid Service prompts and responses are processed under Google's applicable Data Processing Addendum and are not used to improve Google's products, although Google may keep limited logs for safety, abuse prevention, and legal or regulatory purposes. Google's Unpaid Service terms permit broader use and human review of submitted content and instruct users not to submit personal, sensitive, or confidential information. Such student information must therefore not be submitted through an Unpaid Service.

Google's retention and deletion practices may depend on the teacher's billing status, logging choices, region, account, and Google settings. BridgeAIWorks relies on Google's published Paid Service terms and Data Processing Addendum to provide protections consistent with this section for content sent through the paid Gemini API. The teacher should review the current Gemini API Additional Terms and data logging and sharing documentation before submitting student information. BridgeAIWorks limits each transfer to the teacher-authorized app function and does not authorize the transferred information for BridgeAIWorks advertising, tracking, profiling, or model training.

Subscriptions are sold, billed, restored, renewed, and managed by Apple. The app connects to Apple's App Store services through StoreKit to retrieve products and locally verify subscription entitlement. BridgeAIWorks does not receive payment-card details. Apple may provide BridgeAIWorks with aggregate sales and subscription reports and anonymous transaction identifiers.

This edition contains no third-party analytics, telemetry, crash-reporting SDK, advertising, or cross-app tracking. It does not create a device fingerprint, use a machine identifier for licensing, or contact a BridgeAIWorks licensing server. PDF generation uses the app's bundled typesetting engine, fonts, and packages and does not fetch TeX packages from the network.

Teachers are responsible for having the authority and any consent required to process student or third-party information and to send selected content to Google. Before using AI features with student work, teachers should review institutional rules and Google's applicable terms and privacy practices.

Teachers can delete students, batches, exams, grading history, and other local records using the app's controls. Removing the Gemini API key in Settings prevents future AI requests but does not delete information already processed or retained by Google. BridgeAIWorks cannot access or delete that Google-held information; the teacher must use the controls provided by the applicable Google account or contact Google. Before uninstalling, remove local records and the Keychain item from within the app if they should be deleted; deleting the app binary alone may not remove its sandbox container or Keychain item. Subscriptions can be managed or cancelled through Apple.

AI Provider / BYOK Data Handling

Some BridgeAIWorks apps may support bring-your-own-key, or BYOK, workflows. When a user enters an API key for an AI provider, the key is used to send user-requested content to that provider.

API keys should be stored using secure platform mechanisms where supported, such as Apple Keychain or Android Keystore, and should not be saved in plain text. Users should keep their API keys confidential and revoke keys with the provider if they believe a key has been exposed.

BridgeAIWorks does not control how external AI providers process data once the user chooses to send content to them. Users should review the selected provider's privacy policy, retention settings, and data-use terms before enabling AI features.

Data Retention and Deletion

Local app data generally remains on the user's device until the user deletes it, resets the app, removes app data through the operating system, or uninstalls the app. If a feature uses cloud storage, sync, support email, AI providers, OCR providers, crash reporting, or other external services, retention may follow the relevant provider's rules.

Users may contact support@bridgeaiworks.com to request help with data export or deletion. For data stored only on the user's device, BridgeAIWorks may not be able to access, recover, or delete that data remotely.

Children / Students

BridgeAIWorks apps may be used for learning, study, teaching, or productivity. Some content may relate to students or minors if entered by a parent, teacher, school, or user. Users are responsible for obtaining any required consent before entering student, child, school, or third-party information into an app or sending it to an AI provider.

BridgeAIWorks does not knowingly sell children's personal information and does not use advertising tracking in its apps.
