Lumika Terms of Service

Last updated: 24 July 2026

Agreement

By using Lumika, you agree to these terms. If you don't agree, please don't use the app.

The service

Lumika is a language-learning app. It teaches vocabulary and basic conversation through your camera, a spaced-repetition review system, and AI-assisted features (dictionary enrichment, object identification, conversation practice). No account or sign-up is required — your learning data lives on your device.

Subscriptions and purchases

Lumika Pro is offered as an auto-renewing monthly or annual subscription, or a one-time lifetime purchase, billed through Google Play. Subscriptions auto-renew unless canceled at least 24 hours before the current period ends; manage or cancel anytime through Google Play's subscription settings. Annual subscriptions may include a free trial period, clearly disclosed before purchase. All prices are as shown at checkout via Google Play, which may vary by region. Refunds are handled according to Google Play's refund policies.

Fair use

AI-powered features (camera object identification, dictionary enrichment, conversation practice) have daily usage limits to keep the service sustainable, even on paid tiers. These limits are described in the app and may be adjusted from time to time.

Acceptable use

Don't use Lumika to attempt to extract, scrape, or abuse the underlying AI services beyond their intended use in the app. Don't attempt to reverse-engineer, decompile, or interfere with the app's operation beyond what applicable law permits.

Your content

Camera images you point at are processed to identify objects for learning purposes, as described in the Privacy Policy. Text you select for lookup is processed on-device. You retain all rights to anything you input; we claim no ownership over it.

Intellectual property

Lumika's dictionary content draws from Wiktionary (CC BY-SA) and FrequencyWords (CC-BY) data, used under their respective open licenses. See the in-app Attributions screen (Settings → Attributions) for the complete list of third-party components and their licenses.

Disclaimer

Lumika is provided "as is." Language content, AI-generated examples, and identification results may occasionally be imperfect — Lumika is a learning aid, not a certified translation or reference source. We don't guarantee uninterrupted or error-free operation.

Limitation of liability

To the extent permitted by law, we aren't liable for indirect, incidental, or consequential damages arising from your use of Lumika.

Changes

We may update these terms or the app's features over time. Continued use after a change means you accept the updated terms. Material changes will be reflected in the "Last updated" date above.

Termination

You can stop using Lumika anytime by uninstalling it — Settings → Delete everything also removes all local learning data immediately, in addition to uninstalling. We may suspend access for violations of these terms.
