Privacy Policy
Ildan is a voice tutor for language speaking practice. This page explains what data the service handles and why, in plain language.
What we collect
- Account: your email address and name, provided by Google when you sign in (or by you, if you sign in by email link).
- Learning data: transcripts of your practice conversations, and the learning profile built from them: vocabulary you are working on, recurring mistakes, progress and practice-time statistics. This is the core of the product: it is how your tutor remembers you between sessions.
- Billing records: what you purchased and when, and the speaking time credited. Payments are processed by Stripe; your card details go directly to Stripe and never touch our servers.
- Technical: a session cookie to keep you signed in, and a one-way hash of your IP address used only to limit free-trial abuse. Your raw IP address is not stored. App settings live in your browser's local storage.
Voice audio
During a session your microphone audio streams directly from your browser to Google's Gemini API, which powers the conversation. Ildan's servers never receive or store your raw audio. Google transcribes the conversation, and those text transcripts are stored with your account. Google processes audio under its own terms of service.
How we use your data
To run the service: personalizing your tutor, tracking your progress, and managing your credits. That is all. We do not sell your data, show ads, or run third-party analytics or tracking scripts.
Where it lives
Data is stored on our servers, with daily encrypted backups on Cloudflare R2. Service providers we rely on: Google (conversation AI), Stripe (payments), Cloudflare (network and backups), and Resend (email delivery, where enabled).
Deleting your data
Ask through the in-app contact form and we will delete your account, including transcripts and your learning profile, from live systems. Backup copies expire as backups rotate.
Changes
Ildan is in beta and this policy may be updated as the service evolves; the latest version always lives at this address. Questions? Use the contact form in the app.
