Privacy Policy

Last updated: November 7, 2026

Streal (“we”) is a web app for learning languages with YouTube videos. This policy explains what data is processed, why, and with which providers. We follow a data-minimization principle.

1. Data we process

• Account: if you sign in, your email address and Google identifier. Streal never creates or stores a password.
• Learning data: your level, progress, saved words and review history. Stored in your browser and, if you're signed in, synced to your account.
• Payment: if you subscribe to Premium, payment is handled by Stripe. We never see or store your card details; we only keep your subscription status.
• Earlier sign-ups: if you joined our waitlist or asked for an install link, we hold the address you entered, your site language, and the page and campaign you came from.
• Messages you send us: if you use the app's contact form, the text you write, your interface language, your plan and, if you're signed in, your account email.

2. Purposes and legal basis

We process this data to provide the service (performance of the contract): your lessons and progress, your account and your subscription. Account sync is based on your choice to sign in.

Earlier sign-up addresses are processed on the basis of your request, only to answer it and to understand which pages brought sign-ups. No newsletter, and they are never sold or shared.

Messages sent through the contact form are processed on the basis of your request, only to answer it and to improve Streal.

3. Providers

• Google: sign-in (email, identifier).
• Stripe: payment processing and subscription management.
• Google Analytics: audience measurement on our website (streal.app).
• YouTube API Services: videos play in YouTube's embedded player. On our homepage the player only loads when you press play; on our demo video page and in the app it loads when you open the page or the video. From then on, YouTube may set cookies and collect data under its own terms. Streal uses YouTube API Services: by watching a video you agree to the YouTube Terms of Service, and Google's handling of your data is described in the Google Privacy Policy.
• Hosting, database and email providers, which process data on our behalf.

These providers may process data outside the European Union under appropriate contractual safeguards.

4. Retention

Data in your browser stays there until you clear it. Account data is kept as long as your account exists, and you can request its deletion at any time. Waitlist addresses are kept until we have told you Streal is open, and for 12 months at most. Install-link requests are kept for up to 12 months.

5. Your rights

Under the GDPR you have rights of access, rectification, erasure, restriction and portability. To exercise them, email us at streal.learn@gmail.com. You can also clear your local data from your browser's settings.

6. Cookies and tracking

The app itself uses no advertising cookies or trackers. Your progress is stored in your browser and is not used to target you.

Our website (streal.app) uses Google Analytics 4 to measure audience (pages viewed, approximate location, device and browser, which buttons are clicked and how far the page is scrolled) and improve the site. Google may set cookies or identifiers for this purpose and may process data outside the European Union under appropriate safeguards. These measurements are aggregated and never used for advertising: we run no advertising pixel, and Google Analytics is configured with IP anonymisation and with Google Signals and ad personalisation switched off. You can opt out via the Google Analytics opt-out browser add-on or by blocking cookies in your browser.

7. Changes

This policy may change. The “last updated” date above reflects the latest version.
