Privacy Policy
Vocabilis (app.vocabilis.com) and the Vocabilis browser extension. Last updated: November 11, 2026.
Vocabilis is a language-learning service operated by Linguistador LLC (Wyoming, USA) ("we", "us"). This policy explains what we collect, why, who processes it on our behalf, and your choices. Contact: support@linguistador.com.
What we collect
- Account data: email address, first and last name, native language, password (stored only as a salted hash), and your news preference.
- Learning data: the courses, lessons and cards you create or study, your study and review history, and your settings.
- Texts you add: texts you paste or save from the browser extension, with their source page address and title, and the lessons, translations and explanations prepared from them.
- Payment data: if you subscribe, your subscription status and the payment provider's customer reference. Card details are entered at the payment provider and never reach us.
- Notification data: if you enable push reminders, your browser's push subscription.
- Usage and technical data: pages viewed in the app (Google Analytics), error reports with technical details (browser, error message), and server logs (IP address, request time) kept for security and troubleshooting.
The browser extension
The Vocabilis extension for Chrome and Edge lets you save a web page, or the part you select, to your Vocabilis Inbox.
- It reads a page only when you ask: by clicking its icon, choosing "Capture selection with Vocabilis", or pressing its shortcut. It does not read pages in the background and does not record your browsing history.
- The captured text, the page address and title, and the language you choose are kept in your browser until you save them. When you click Save, they are sent only to Vocabilis (app.vocabilis.com) and stored in your account. Nothing is sent anywhere else.
- To connect, Vocabilis gives the extension a revocable access token that can only save texts and read your study languages. You can disconnect it in the extension or in Profile → Connected extensions.
- The extension contains no analytics or advertising code.
The use of information received from the extension adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements: we use it only to provide the feature you asked for, we do not sell it, we do not use it for advertising or credit decisions, and people read it only with your permission, for security, or as the law requires.
How we use data
- To provide the service: your account, your lessons, Study and Review, and preparing texts you choose to prepare.
- To send emails you need (password reset, review reminders you turned on) and, if you opted in, product news.
- To process payments, prevent abuse, fix errors and understand which parts of the app are used.
We do not sell personal data, and we do not use your texts to train AI models ourselves.
Who processes data for us
| Provider | Purpose | What they receive |
|---|---|---|
| AI providers (OpenAI, OpenRouter, DeepSeek) | Preparing a text you chose to prepare: translations, explanations, word lists | The text being prepared and the languages involved; not your name or email |
| Microsoft Azure Speech | Pronunciation audio | The words or sentences to be spoken |
| Stripe, YooKassa | Subscriptions and payments | Email and payment details you enter with them |
| Google Analytics | Which app pages are used | Page views and device information, under a pseudonymous identifier |
| GlitchTip / Sentry | Error reports | Technical error details, with personal data removed where possible |
| Email provider | Sending emails | Your email address and the message |
Our servers and these providers may be located outside your country. We share data only as needed for the purposes above, or when the law requires it.
Retention and your choices
- We keep your data while your account exists. Server logs are kept for a limited time.
- You can edit your profile, delete lessons and texts you created, turn off reminders, disconnect the extension, and unsubscribe from news.
- To get a copy of your data or delete your account, write to support@linguistador.com. Depending on where you live (for example the EU/EEA or the UK), you may also have rights to object, restrict processing, or complain to a data protection authority.
Children
Vocabilis is not directed to children under 13, and we do not knowingly collect their personal data. A parent or guardian may use Vocabilis with a child under their own account. If you believe a child under 13 gave us personal data, contact us and we will delete it.
Security
Connections are encrypted (HTTPS), passwords are hashed, and access tokens are revocable. No method is perfectly secure, but we work to protect your data.
Changes
We will update this page when our practices change and change the date above. For significant changes we will notify you in the app or by email.
