Legal
Terms of Use
These terms apply to Contos on iPhone and iPad and to the Contos web app. By using Contos you agree to them.
The service
Contos helps you learn a language by reading: a library of serialised stories written at your level, a personalised story each day, mini-lessons, tap-to-translate and flashcards, in 17 languages. Stories, translations and lessons are AI-generated for language practice — they may occasionally contain errors and aren't professional advice of any kind.
Free and Premium
Contos is free to use with limits: the first two chapters of every series are free. Contos Premium unlocks every chapter, the daily personalised story and the rest of the paid features. Premium is a monthly plan (one month) or an annual plan (one year), at the price shown before you confirm your purchase. There is currently no free trial — the free chapters are there so you can try Contos first.
Premium belongs to your Contos account, so it works on both iPhone/iPad and the web when you're signed in to the same account, whichever one you bought it on.
Buying on iPhone or iPad (App Store)
- Billing: payment is charged to your Apple ID at confirmation of purchase.
- Renewal: the subscription renews automatically for the same period unless cancelled at least 24 hours before the end of the current period; the renewal is charged within 24 hours before the new period starts.
- Managing & cancelling: Settings → your name → Subscriptions on your device.
- Refunds are handled by Apple under the App Store terms.
Buying on the web
- Billing: payment is taken by card when you confirm your purchase. Checkout and billing are run by our payment providers, RevenueCat and Stripe; we never see your full card details.
- Renewal: the subscription renews automatically at the end of each period — monthly or yearly, depending on your plan — and your card is charged at the start of each new period, until you cancel. If the price changes, we'll tell you before it applies to your next renewal, and you can cancel before then.
- Managing & cancelling: in the web app go to Account → Manage subscription, or email us. You can cancel at any time; you keep Premium until the end of the period you've paid for, and you won't be charged again.
- 14-day refunds: if you change your mind, email hello@contosapp.com within 14 days of your first payment, or of an annual renewal, and we'll refund that payment in full. Outside these 14 days, payments for a period that has started aren't refundable, except where the law says otherwise — cancelling stops future renewals.
Deleting the app or your Contos account does not cancel a subscription — cancel it first as described above.
Your account
Contos starts you on a guest account. You can make it permanent by signing in with Apple (on iPhone and iPad) or by signing up with your email address and a password (on the web). Until you do, your progress is tied to this device or browser, and clearing your browser's data can lose access to a guest account. Keep your sign-in details to yourself — you're responsible for activity on your account. You can delete your account at any time (Account → Delete account); deletion is permanent.
Acceptable use
Don't attempt to abuse, reverse-engineer the service, or gain access you haven't paid for. We may suspend accounts that do.
Liability
Contos is provided "as is". To the maximum extent permitted by law, we're not liable for indirect or consequential losses arising from use of the app. Nothing in these terms limits liability that cannot legally be limited.
Changes
We may update these terms; material changes will be reflected on this page with an updated date. Continued use after changes means acceptance.
