Terms of use

Version of 15 November 2026

1. Who we are

Lingvokey (the Windows app, the Lingvokey Mail browser extension and the lingvokey.eu website) is provided by Oleksandr Strekozov IT, ul. Klonowa 3/19, 91-036 Łódź, Poland (“we”). Contact: hello@lingvokey.eu.

2. The software

We grant you a personal, non-exclusive, non-transferable licence to install and use Lingvokey. The free version can be used without time limit. You may not resell, rent out or redistribute the software, or remove its protection, except where the law allows it.

3. Pro subscription and lifetime licence

Lingvokey Pro is offered as a monthly subscription ($6), a yearly subscription ($49) or a one-time lifetime licence ($89). Prices may include taxes depending on your country. A new account gets a free 14-day Pro trial once; no payment details are needed for it.

Subscriptions renew automatically at the end of each period until you cancel. You can cancel at any time in the app (Settings → Account → Manage subscription); Pro then stays active until the end of the period you paid for. A licence works on up to 3 computers at the same time; devices can be switched in Settings → Account. “Lifetime” means for as long as we develop and support Lingvokey and its sign-in service, and at least 5 years from the purchase.

4. Payments — Paddle

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. Paddle's buyer terms apply to your purchase.

5. Third-party services

Some features use services you connect with your own key — Groq (speech recognition, AI, translation, reading text from the screen), DeepL or Google Gemini (translation). Their terms and pricing apply to that use; we don't control them. Without these keys the features that need them don't work, while layout fixing and offline dictation keep working.

6. Acceptable use

Don't use Lingvokey to break the law, to watch other people's input without their consent or to send spam. You are responsible for the texts you create, translate or send with it; check machine translations before sending important messages.

7. No warranty

Lingvokey is provided “as is”. We work to keep it reliable, but we can't promise it is free of errors or always available, or that automatic fixes and translations are always correct. Nothing in these terms limits your rights as a consumer under the law of your country.

8. Liability

To the extent the law allows, we are not liable for indirect damage or lost profits, and our total liability is limited to the amount you paid for Lingvokey in the 12 months before the claim. This does not limit liability for intent, gross negligence or harm to life and health.

9. Changes and termination

We may update the software and these terms; important changes will be announced in the app or by e-mail in advance. You can stop using Lingvokey and delete your account at any time. We may close accounts that seriously break these terms.

10. Law

These terms are governed by the law of Poland. If you are a consumer in the EU, you also keep the protection of the mandatory law of your country of residence. The EU online dispute resolution platform: ec.europa.eu/consumers/odr.
