Eirelingo Privacy Policy

Last updated: August 23, 2026

Eirelingo is an Irish (Connacht) vocabulary study app built around spaced repetition and native audio. This policy explains what data Eirelingo collects and why, and credits the open data sources and speech technology that make the app possible.

Information we collect

Account. Your email address and password, used to create and sign in to your account. Passwords are handled by our authentication provider (Supabase) and are stored hashed; we never see them in plain text.
Study data. The decks and cards you create or install, and your review history and scheduling (when each card is next due). This is what lets the app track your progress across devices.

How your information is used

To provide the core service: signing you in, syncing your decks and progress, and scheduling reviews.
Audio generation. To produce spoken Irish, the text on a card is sent to a text-to-speech service, which returns an audio file we cache so it doesn't need to be regenerated. Cached audio is shared across users. Card text is not personal information and is not used for advertising.

What we do not do

We do not sell or rent your personal information.
We do not show third-party advertising.
We do not use third-party analytics or tracking SDKs to profile you.

Data storage and providers

Your account and study data are stored with Supabase (our database, authentication, and storage provider). Irish audio is synthesized by the text-to-speech providers listed under Content, data & attribution below. These providers process data on our behalf to operate the app.

Content, data & attribution

Eirelingo's dictionary, grammar, example sentences, and level tagging are built from openly licensed language resources. We're grateful to the projects and communities behind them. Where a licence requires attribution or share-alike terms, the derived data we ship is provided under the same terms.

Dictionary & word glosses

Irish headwords, meanings, and pronunciations derive from Wiktionary, extracted via Wiktextract / kaikki.org. Licensed under CC BY-SA 4.0.

Morphology & grammar

Gender, genitive and plural forms, and initial mutations draw on BuNaMo, the Irish National Morphology Database by Michal Boleslav Měchura, provided under an open licence (CC BY-SA 4.0).

Example sentences

Example phrases and sentences come from the Tatoeba project, licensed under CC BY 2.0 FR.

Level structure

Deck levels follow the TEG (Teastas Eorpach na Gaeilge) syllabi from Maynooth University — A1 to C1. TEG is the reference framework for the levels; Eirelingo is an independent app and is not affiliated with or endorsed by TEG or Maynooth University.

Irish speech audio

Spoken Irish is generated with neural text-to-speech, including Microsoft Azure Neural TTS (ga-IE) and the Connacht (Conamara) synthetic voice from ABAIR, developed by the Phonetics and Speech Laboratory at Trinity College Dublin, with eSpeak NG as a fallback. Eirelingo is not affiliated with these providers; their voices are used under their respective terms.

Deleting your account and data

You can permanently delete your account at any time from within the app: open your profile from the Home screen, then Delete account. This removes your account and all associated decks, cards, and study history. The deletion cannot be undone.

Children

Eirelingo is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children under 13.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.
