Terms of Service

Polski — developed by Seven Sides Technology
Effective date: July 3, 2026

1. Acceptance

By creating an account or using the App you accept these terms. If you do not accept them, do not use the App. The service operator is Seven Sides Technology (the “we”, “us”).

2. What the App is

Polski is a Polish-learning app for Spanish speakers (A1–C2) with vocabulary spaced repetition, a tap-to-translate reader, generated exercises, an AI tutor, speaking and writing practice, and an openly-licensed library.

3. Your account

A valid email is required. You are responsible for your account's security.
The App is for users aged 13 and older.
You may not transfer your account to a third party or share credentials.

4. Acceptable use

You agree not to:

Upload copyrighted material you do not have a license for.
Upload illegal, violent, sexual, hateful, or rights-infringing content.
Reverse-engineer, mass-scrape, or attempt to bypass security controls.
Use the App to send spam or malware.
Present AI-generated content as authoritative or attribute it to the App or its operator.

We reserve the right to suspend or terminate your account without notice for serious violations.

5. Your content

You retain ownership of everything you upload (books, audio, writing).
You grant us a limited, non-exclusive, revocable licence to store and process that content solely to provide the service to you.
When you close your account, we delete your content as described in the Privacy Policy.

6. Curated library (public domain / open licence)

The App ships public-domain and openly-licensed materials (Wikibooks / Wikivoyage CC BY-SA, FSI Polish FAST public domain, and others). Attribution stays with each resource. You may not redistribute this library outside the App without respecting the original licence.

7. Generative AI

AI can be wrong. Translations, exercises, and tutor replies are guidance, not definitive.
Do not use the App as the sole source for critical decisions (academic or professional).
We visibly label AI-generated content (“AI-generated”, “From the books — review pending”).

8. Availability

We aim for 24/7 availability but do not guarantee uninterrupted service. We may run planned maintenance. We are not liable for indirect damages caused by downtime. The App may be offered as a limited test (closed / flight testing) before general release.

9. Pricing (future)

The App is currently 100% free: no ads, no subscription, no in-app purchases. If we introduce paid plans, we will notify you at least 30 days in advance; your current free use will never be auto-converted into paid use.

10. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect damages, lost profits, or data loss caused by use of the App. Our total cumulative liability is limited to the amount you paid in the last 12 months (€0 on the free tier).

Nothing in these terms limits the mandatory consumer-protection rights granted to you by the GDPR or other EU law.

11. Changes

We may update these terms. Material changes are announced in-app 30 days in advance.

12. Governing law and venue

These terms are governed by Spanish law. For consumer disputes the venue is the user's place of residence. For commercial disputes, the competent courts of the operator's registered domicile. Nothing here removes your right to bring proceedings in your EU country of residence.
