Policies

Last updated 20 September 2026.

These policies explain how Fast Conversation works, what we store, and which third parties help run the site. Using the site means you agree to them.

The service

Fast Conversation is a language-practice app. You pick a language and a goal, then take part in scripted conversations by typing or speaking. Guests can try a limited set of A1 conversations. A signed-in account can finish those conversations. A paid plan unlocks every module and level.

Accounts and profile

You can practise without an account. If you sign in with Google or a magic link, we store your email, optional name and photo, your UI language, and your learning progress so it can follow you to another device. You can update your name and photo on the profile page and sign out at any time.

Payments

Paid access is billed by Stripe. Full access is $4.99 per month after a first free month, unless you cancel. We do not store your card number. Stripe stores payment details under its own terms. We keep Stripe customer and subscription IDs on your profile so we can apply and check your plan. Manage billing from the plans page or your account menu.

Voice, scoring, and speech

If you record an answer, that audio is sent to OpenAI to transcribe and score it. We do not keep your recording as a file after the request. Scripted partner lines are turned into speech with OpenAI. Those clips are stored so other learners can replay the same line without generating it again. Typed answers and scores are saved as part of your progress.

What we store

On this device we store progress and interface translations. If you are signed in we also store that progress, your profile, plan status, and support messages on our database (Supabase). Support messages are limited to 10 per UTC day, with a 100-character title and a 1,000-character description. We may email those messages to our support inbox.

Cookies

We use cookies to run the site, keep you signed in, and remember your preferences. Necessary cookies are always on. We do not use advertising or analytics cookies. You can open cookie settings again with the button at the bottom left.

Third parties

Supabase hosts accounts, progress, and stored speech clips. OpenAI powers scoring, hints, translations, transcription, and text-to-speech. Stripe handles checkout and subscriptions. Resend may send support emails if that is configured. Each provider processes data under its own policy, only as needed to provide that part of the service.

Your choices

You can practise as a guest, sign out, cancel a subscription through Stripe, and contact support from the site. You can ask us to correct or delete account data you have given us. Clearing this browser’s storage removes local progress. Some records (such as billing history at Stripe) are kept as required to run payments.

Contact

Use Contact support in the site header when you are signed in. We read every message. These policies apply to the Fast Conversation website and app.
