Privacy Policy
This policy explains which data LinguaFox processes, why it is needed, and which choices you have.
Cookies and local storage
LinguaFox uses a necessary sign-in cookie to keep authenticated sessions secure. Local storage remembers language and workspace preferences and your acknowledgement of the cookie notice. On pages with wallet payments, supported PayPal, Apple Pay, and Google Pay scripts may load to check availability and render payment buttons; those providers may process technical browser or device information under their own policies. We do not use these payment scripts for advertising or analytics.
Data we process
We process account details, language preferences, saved vocabulary, lessons (including full lyrics in saved song lessons), Coach transcripts and summaries, usage records, Fox Tails transactions, payment-provider order references, referral codes and relationships, and technical logs required to operate and secure LinguaFox.
Why we process it
Data is used to authenticate you, synchronize your workspace, personalize learning, provide AI and voice features, calculate usage, process payments, prevent abuse, and improve reliability.
Service providers
LinguaFox may use Supabase for authentication and data, OpenAI for AI and voice processing, Cloudflare R2 for cached audio, Amazon SES for email, PayPal for payments and its card, Apple Pay, and Google Pay integrations, and hosting or monitoring providers. Each provider receives only the data needed for its role.
Payments
When you use PayPal, a debit or credit card, Apple Pay, or Google Pay for a top-up, LinguaFox sends the selected package, amount, your authenticated account email, and payment method to PayPal to create and verify the order. PayPal-hosted card fields and the Apple Pay or Google Pay wallet sheet send payment details directly to PayPal for processing; Apple Pay may also provide billing contact fields you approve. LinguaFox does not receive or store your full card number or wallet credentials. We retain the provider order reference, status, captured amount and currency needed to credit Fox Tails, prevent duplicate credits, handle support, and meet accounting and legal obligations.
Audio and Coach sessions
Voice input is sent for transcription and response generation. Uploaded video and audio are stored temporarily while they are processed and then deleted. Session summaries may be stored in your account so they remain searchable. Cached lesson audio may be stored to reduce latency and repeated generation costs.
Retention and deletion
Your workspace data is retained while your account is active. Deleting an item removes it from the active workspace. Deleting your account initiates removal of associated lessons, vocabulary, Coach history, and cached user assets, subject to security logs, payment records, backups, and legal obligations.
Your choices
You can edit profile preferences, delete individual saved content, and request account deletion. You may contact us to request access, correction, export, or deletion where applicable law provides those rights.
Security and changes
We use reasonable technical and organizational safeguards, but no online service is risk-free. Material policy changes will be published here with a revised date.
