Who we are
Fluent Air is a flashcard app for learning languages, run by Gabriel Domingos, Montreal, Canada. Contact for anything about your data: [privacy contact email].
What we collect
| Data | Why | Kept |
|---|---|---|
| Email address, and password (stored only as a secure hash by our sign-in provider) | Create your account, sign you in, send sign-in links | Until you delete your account |
| Your study content: decks, cards, notes, notebook words, tags, images and audio you add or generate, files imported from Anki | Provide the app and sync it across your devices | Until you delete it or your account |
| Study history: your answers to cards and when you gave them, settings | Schedule reviews (spaced repetition) and show your statistics | Until you delete your account |
| AI usage records: which AI feature you used, which provider, how much, and when | Plan quotas, cost control, billing | [24 months], then deleted or anonymised |
| Technical logs: IP address, device/browser type, request times and errors | Security, preventing abuse, fixing bugs | A few days |
| Payment data (when paid plans launch) | Charge your subscription | Handled by our payment processor; we only see the plan, status and last digits of the card |
We do not sell your data, show ads, or use advertising or analytics trackers. The app keeps your sign-in session and a copy of your content in your browser so it works offline; these are not tracking cookies.
Who processes your data
These service providers only get what they need to do their task:
| Provider | What it does | Data it receives | Where |
|---|---|---|---|
| Supabase | Database, sign-in, file storage | All the data above except logs | Brazil (São Paulo) |
| Cloudflare | Hosts the app and our API, draws AI images | Technical logs; the short English scene description used to draw an image | Worldwide |
| Google (Gemini API, paid tier) | Example sentences, translations, corrections, word explanations | The word you look up, your optional note about where you saw it, a few sentences and words already in your deck, the card text you ask it to check or explain | United States |
| [Voice provider] | Reads sentences aloud | The sentence or word to be read | [region] |
| Pixabay / Pexels | Free stock photos | A 1–3 word search term (no account data) | Germany / Canada |
| [Stripe] (when paid plans launch) | Payments | Your email, payment details | United States |
These providers may process data outside your country. Where the law requires it (for example Quebec's Law 25, GDPR or Brazil's LGPD), we rely on the providers' contractual safeguards. We use AI plans in which providers do not use your content to train their models.
Tip: don't put sensitive personal information (health, passwords, ID numbers) in your cards. Card text is sent to the AI providers when you use AI features.
Legal bases
We process your data to provide the service you signed up for, to keep it secure and prevent abuse, and to meet legal obligations such as tax records for payments.
Your rights
- Access and export: export your decks to Anki format from the app.
- Correct: edit any card or setting in the app.
- Delete: delete cards and decks in the app, or your whole account in Settings → Delete account. It erases everything at once, on every device, except what the law requires us to keep (for example payment records).
- Ask or object: contact [privacy contact email]. We reply within [30 days].
You can also complain to your data protection authority: in Quebec the Commission d'accès à l'information, elsewhere in Canada the Office of the Privacy Commissioner, in the EU/UK your national authority, in Brazil the ANPD.
Children
Fluent Air is not meant for children under [16]. If you believe a child gave us data, contact us and we will delete it.
Security
Data travels encrypted (HTTPS). Each user can only reach their own data (row-level security in the database, private file storage). No system is perfectly secure; if a breach affects you, we will tell you as the law requires.
Changes
If we change this policy in a way that matters, we will tell you in the app or by email before it takes effect.
