Credits & Licences

Everything in Dentalingo that we did not make ourselves, and the terms it is used under. The same information ships inside the app under Profile → Licences & credits, where each image carries its own creator, licence and source link.

Where an image was cropped, rotated or otherwise modified, the app's credit line says so, as the licence requires. Share-alike works are used in a way that preserves those terms.

Sources

Wikimedia Commons — the main source, used under each file's stated licence.
The NIH/NLM PubMed Central Open Access Subset. This bundled snapshot may not reflect the most current data available from NLM. Dentalingo is not endorsed by, and makes no claim of affiliation with, NLM, NIH or PMC.

No NLM, NIH, PMC or Wikimedia logo or wordmark is used anywhere in the app or its marketing.

Sound

All sound effects come from Kenney audio packs (Interface Sounds, Digital Audio, Music Jingles), released under CC0. Files were converted to Core Audio Format for playback; the audio is otherwise unmodified.

Rights holders

If you are the creator or rights holder of a work used in Dentalingo and you believe a credit is wrong, incomplete, or that your work should not be included, email hello@laborsam.com. We will correct the credit or remove the work promptly — no argument required.
