Privacy Policy
This policy explains how LugMIND handles information when you use its learning features, account tools and contact form. These legal pages are currently provided in English. For privacy, legal, account or general inquiries, contact info@contactory.co.
The learning service
LugMIND helps you turn uploaded or imported learning materials into courses, lessons, quizzes and flashcards. It supports AI tutor conversations, voice transcription, narration, photo text extraction, study progress and optional credit purchases or subscriptions. Some features require an account or credits.
Information you provide
We process the material you upload or import, extracted text, document names and course settings; questions, tutor conversations and recordings you submit for transcription; generated learning content, quiz activity and progress; and account details such as email, account identifiers and optional profile information. When you contact us, we collect your name, email, category, subject and message. Do not send passwords, payment-card details or unnecessary sensitive information.
AI processing and its limits
Relevant material, excerpts, questions and conversation context may be sent from your device to our server and to AI providers to produce learning content and answers. Voice features may send recordings for transcription and text for narration; photo OCR may send images for text extraction. An anonymous preview also processes an excerpt of your material. AI processing is not entirely on your device. Only share material you have permission to provide. AI output can be inaccurate, and an automated support check is not a guarantee of correctness.
Local storage and cloud storage
Courses, extracted source text, generated lessons, conversations, progress, preferences and some audio are kept locally on your device or browser. When you sign in, supported course content, conversations, progress and settings can also be backed up or synchronized to your account. Clearing browser storage or deleting the app may remove local data without deleting cloud copies. Cloud backups are not a promise that every original file or audio recording is archived or restored.
Server-side records
The app uses PostgreSQL/cloud storage for account-linked learning data, course backups, generated results and job status, search chunks and indexes, credit and subscription records, settings and contact inquiries. Generated narration and other results may be cached to improve performance and avoid repeated work or charges. We also process operational metadata, such as request timing, errors, usage, service costs and abuse-prevention identifiers. Authentication uses session information; preferences and learning data use device/browser storage.
Why information is used
Information is used to deliver and personalize the learning service, authenticate accounts, preserve progress, synchronize supported data, process purchases and credits, respond to inquiries, operate and troubleshoot the app, prevent misuse and meet applicable obligations. Contact inquiries are stored with a timestamp and handling status in an owner-restricted inbox. Submitting a contact form does not subscribe you to marketing. Email notifications to the owner are only attempted when an email provider is configured; database receipt is not proof of email delivery.
Third-party providers
The application is configured to use Clerk for authentication; PostgreSQL/cloud and local device storage; Replit AI Integrations with Anthropic as the default text backend or an optional OpenAI-compatible text backend; OpenAI-compatible audio transcription/narration and vision OCR; Stripe for web billing; and RevenueCat for mobile purchases through the applicable app store. Public book or webpage imports contact the selected external source. Hosting, email and other infrastructure providers may also process data needed to operate the service. An optional Resend integration notifies the owner of contact inquiries when configured, without including your message body or email in the notification. Actual provider availability and configuration can vary. Providers and purchase stores have their own terms and privacy practices; this policy does not promise particular provider retention, training restrictions or deployment settings.
Billing information
The app stores purchase-provider/customer identifiers, subscription state, credit balances, transaction and usage records, and applicable billing preferences. Checkout and payment-method handling are performed through the applicable payment provider or store rather than the contact form. We do not ask you to submit payment-card details in an inquiry.
Sharing and access
Information is made available to service providers as needed for the features you use and to authorized operators handling service administration or support. We may also disclose information when required by applicable law or reasonably needed to address fraud, safety, security or legal claims. Contact messages are not a public discussion board and are not available to ordinary users through the app. No system can guarantee absolute security; avoid uploading confidential material unless you are authorized and comfortable with this processing.
Retention and deletion
Retention varies by record type and operational need. Local data remains subject to your device/browser storage controls. Server results, search indexes, caches, account records and support correspondence have different lifecycles; some generation records are kept to recover work and prevent duplicate charges. We do not promise one fixed retention period or instant erasure. Account deletion removes linked data through the app’s deletion paths, but cannot instantly erase all provider-held copies, shared caches, logs or backups. Records may also need to be retained for legitimate operational, security, billing or legal purposes. Contact inquiries are not automatically tied to an account and may require a separate deletion request.
Your choices and requests
You can manage available profile and account settings, remove local courses, clear device/browser data or use the account-deletion option. To request access, correction or deletion of information, or ask about rights available under applicable law, email info@contactory.co or use Contact Us. We may need to verify your identity and clarify the request. Do not include your password. Deleting an account or the app does not necessarily cancel subscriptions: cancel with the applicable provider or store.
Updates and questions
This policy may be updated as the service and its processing change. Changes will be reflected on this page, with additional notice where required by applicable law. If you have questions about a particular feature, provider, child’s information or data request, contact info@contactory.co.
