A language-learning app with lessons, review, and spoken conversation practice with an AI partner. It is early software in beta, and it changes — features can be added, altered or removed while we work out what helps people learn.

An account is for one person. Keep your password to yourself; anything done with your account is treated as done by you.

7 days, no card required. You get the whole product. If you never subscribe, you are never charged — there is nothing to cancel and no card on file to forget about.

The price you see before you subscribe, charged when your trial ends and then on the schedule you chose — monthly or yearly — until you stop it. Payments run through Stripe. Card details go straight to Stripe and never reach our servers.

One exception: subscribe in the last 49 hours of your trial and you are charged straight away rather than when the trial would have ended. Stripe will not carry a trial that short into a subscription, so the hours left on it are lost. Subscribe before then and nothing is charged until your 7 days are up.

The first 100 people to subscribe pay $9.99 a month or $99.90 a year and keep that price for as long as their subscription stays active. If you cancel and subscribe again later, you pay whatever the price is then.

You get 7 days to fix your card before access pauses. We would rather give you a week than lock you out over an expired card. Update it in the billing portal and access resumes as soon as the payment goes through.

Switching between monthly and yearly is done in the billing portal, and it keeps the same subscription rather than starting a new one — which is how a founding price survives the change. Moving to the longer plan takes effect straight away. Moving to the shorter one takes effect when your current period ends, so you keep every day you have already paid for; nothing is refunded because nothing is lost.

Any time, from the billing portal in your account. No email required and nobody will try to talk you out of it. Canceling stops the next payment. You keep access until the end of the period you have already paid for.

Email us within 30 days of a charge and we will refund it. No questions and no form. That covers the most recent payment; if something went wrong further back, write to us anyway and we will sort it out. contact@adevious.com

Spoken conversation costs us money for every minute, so there is a weekly limit — currently 45 minutes per week. The app tells you when you have used it up, and it resets on Monday. If the cap is getting in your way, tell us; it is a number we picked, not a law.

Your lesson answers and conversation transcripts are yours. We keep them so you can read them back and so the app can track your progress. The privacy page explains exactly what is stored, who else sees it, and how to have it deleted.

Do not share one account between people, resell access, try to break or overload the service, or use the AI partner to generate things that are illegal or abusive. This is a practice tool for learning a language — use it as one.

We can suspend or close an account for the things above, or for non-payment. If we do, we will tell you why, and we will refund anything you have paid for time you cannot use.

This page carries the date it was last updated. If something material changes — the price, the refund policy, what we do with your data — we will tell you rather than quietly editing the page.

Write to contact@adevious.com. A person reads it.
