Terms

Version of 18 October 2026

1. Who we are

Convola is run by Solid Software B.V., Rümkelaan 32, 3571 XW Utrecht, the Netherlands. Chamber of Commerce 94194432, VAT NL866673520B01. Contact: support@solid-soft.nl. The company facts are also on the imprint.

2. What Convola is

Convola lets you practise Spanish, Italian and Dutch by talking with characters in everyday situations. The characters and the tutor are AI. They can make mistakes, and Convola is not a certified course or exam.

Your levels are the AI's judgement of your conversations, not a certificate. After each conversation the AI rates the skills you used. A level moves one step only after three ratings in a row point the same way. You can set a level yourself at any time.

3. Your account

An account is for one person aged 16 or older. You sign in with a code we mail you, or with Google. Keep access to your email: it is how you sign in. To change the email of your account, mail support@solid-soft.nl from the old address.

4. Free trial

A new account gets a free trial of 7 days with a set amount of practice. No card is needed. One trial per person.

5. Plans and practice allowance

A plan runs monthly or yearly at the price shown on your account page, VAT included in the EU. Each month of a plan includes a practice allowance, shown as a bar. Each day has a share of it; when today's share is used you can take more of the month's allowance. Practice you do not use ends with the month. When the month's allowance is used, practice pauses until the next month starts. A yearly plan gives the same allowance every month. You can switch between monthly and yearly on your account page; Stripe settles the difference for the rest of the period.

6. Payment and renewal

Stripe handles payment; we never see your card number. A plan renews by itself until you cancel. Before a yearly plan renews, Stripe mails you a reminder.

After a yearly plan has renewed, you may end it at any time with one month's notice. We then refund the full months left after that.

7. Price changes

We may change the price of a plan. We mail you at least 30 days before a new price applies to you, and it applies from your next renewal. If you do not agree, cancel before then. A price you already paid never changes.

8. Cancelling

Cancel at any time with the button "Cancel subscription" on your account page. Your plan then runs to the end of the period you paid for. We do not refund part of a period, except where these terms or the law say so.

9. Right of withdrawal

In the EU you may withdraw from a purchase within 14 days, without giving a reason. Use the withdrawal form, the model form on that page, or mail support@solid-soft.nl. When you buy a plan you ask us to start at once. If you then withdraw, you pay for the practice you used until you told us, and we refund the rest within 14 days, to the card you paid with.

10. Codes

A promotion code adds practice for 30 days from the day you redeem it. Each code works once and has no cash value.

11. Fair use

Do not share your account, use scripts or bots, or try to make the AI produce harmful content. We may pause an account that does, after telling you why.

12. Your conversations

What you type or say stays yours. We store it to run your practice, as set out in the privacy statement.

13. Legal guarantee

You have the legal guarantee for digital services: Convola must work as these terms describe for as long as your plan runs. If it does not, tell us and we fix it. If we cannot fix it within a reasonable time, you may end your plan and we refund the part of the period it did not work.

14. Liability

We do our best to keep Convola working and correct, but cannot promise it never fails. As far as the law allows, we are not liable for indirect loss, and our liability is at most what you paid us in the 12 months before the damage. These limits do not apply to damage we cause on purpose or by gross negligence. Nothing here limits your rights as a consumer.

15. Complaints

Mail a complaint to support@solid-soft.nl. We answer within 14 days. If we cannot solve it together, you may take it to the court or the consumer body of the country where you live.

16. Changes

We mail you at least 30 days before a change that matters to you. If you do not agree, you can cancel before it takes effect.

17. Law

Dutch law applies. The consumer protection of the country you live in stays in force.
