Privacy Policy
This policy explains what Translate Flashcards collects and why. Translate Flashcards is operated by DEVEXITY LLC, Colorado, USA ("we," "us"). It covers the web app at app.translateflashcards.com, the Chrome extension and translateflashcards.com. We don't sell your data, show ads, or use your phrases for anything except running the Service for you.
What we collect in the app
| Data | Why | Where it's stored or sent |
|---|---|---|
| Name, email and account ID from Google sign-in | To create your account and sign you in | Google Firebase |
| Phrases, translations, notes, tags, review history and settings | To keep your phrasebook and sync it across devices | Google Firebase (Firestore) |
| Text you translate, your note, your region setting and any default instructions | To produce the translation and explanation | Sent to OpenAI for processing |
| Text you play with natural voices (Pro) | To produce spoken audio | Sent to Google Cloud Text-to-Speech. On the free plan, audio uses your device's own voice and nothing is sent |
| Subscription status and Paddle customer and subscription IDs | To know which plan you're on | Google Firebase |
| Whether and when you imported from the Chrome extension, how many cards, and whether you qualify for the founding-member price | To set your card limit and apply the right price | Google Firebase, kept with your account |
| Payment details, billing address and tax information | To process payments | Collected and held by Paddle, not by us |
| Request counts per minute and per day | To enforce usage limits and prevent abuse | Google Firebase, kept briefly |
| Usage events: which features you use and when (for example a translation, a saved card, a review session, a plan change), the language pair, your plan, and which link you arrived from. Never the text of your phrases or your email | To understand how the app is used and improve it | PostHog (analytics), linked to your account ID |
The app also saves display preferences in your browser's local storage and caches its own files so it loads quickly. The app has no advertising. Its usage events (above) go to PostHog without cookies: PostHog keeps its identifiers in memory only, and doesn't record your screen or the text you type.
What the Chrome extension collects
- Your phrasebook stays in your browser. The extension reads the phrases you saved in Google Translate while that page is open and stores them, with your tags, notes and progress, in your browser's extension storage. We don't receive them.
- Import is your choice. If you open the app and choose Import from extension, the extension hands your phrasebook to the app, which saves it to your account as described above.
- Anonymous usage statistics. The extension sends Google Analytics a random installation ID, the features you use (such as button clicks), your browser and operating system, the approximate size of your phrasebook, and your most common language pair. It does not send your phrases.
This website
translateflashcards.com doesn't use cookies. It counts visits with PostHog in a cookieless mode: the pages viewed, the site that referred you, and your browser, device type and approximate location (country or region). Your IP address is used only to count unique visitors for the day and isn't stored, and no profile of you is created. If you fill in a form (contact, feedback or updates), your answers are collected by Tally, our form provider, and sent to us.
Service providers
We use Google (Firebase, which also hosts the app and this website, and Cloud Text-to-Speech), OpenAI, Paddle (our reseller and Merchant of Record), Tally (website forms), PostHog (analytics for the app and this website) and Google Analytics (extension only). They process data only to provide their services to us, under their own terms and privacy policies. OpenAI's API terms state that it does not use API data to train its models.
Where data is processed
Our providers are based mainly in the United States and the European Union, so your data may be processed there.
How long we keep it
We keep your account data until you delete it or ask us to. The per-minute and daily counts used for usage limits expire within days. Paddle keeps transaction records as tax law requires.
Your choices and rights
You can edit or delete phrases in the app at any time. Email support@translateflashcards.com to get a copy of your data, correct it, or delete your account and everything in it; we'll respond within 30 days. Depending on where you live (for example the EU, UK or California), you may have further rights, including the right to object to processing or to complain to a data protection authority.
Children
The Service is not directed at children under 13, and we don't knowingly collect their data.
Security
Data is sent over encrypted connections and stored with providers that encrypt data at rest. Access is limited to your own signed-in account and to us for support.
Changes
We'll post updates here and notify you in the app or by email of material changes.
