1. Scope

This Privacy Policy explains how Mintech processes personal data when users install the extension, use it without registration, create an account, use translation and vocabulary features, click or select YouTube subtitles, upload or convert documents, access learning features, make payments, contact support, or visit related websites.

2. Categories of personal data

We may process:

• account data such as email address, name if provided, country, language settings and login data;
• technical data such as IP address, browser, device, extension version, operating system, event logs and security logs;
• payment-related identifiers such as payment provider customer ID, transaction ID, subscription status and invoice data;
• usage data such as selected words or phrases, subtitle snippets, document fragments, saved vocabulary, generated card data, learning progress, timestamps and feature usage;
• uploaded files and converted outputs where document conversion is requested;
• support communications;
• cookie or analytics data where applicable.

3. Website, subtitle and document content

The extension is designed not to automatically read web pages in the background for transfer to Mintech servers.

When the user selects text, clicks a supported subtitle, uploads a document or requests translation, saving or conversion, the relevant word, phrase, subtitle text, document, document fragment, converted output and contextual sentence necessary for the requested feature may be processed.

4. Document conversion

When document conversion is requested, the uploaded file and converted output may be transmitted to Convertio or another file-conversion provider.

Users should not upload confidential, highly sensitive or third-party personal data unless they have the required rights and accept that files may be processed by third-party conversion providers.

5. YouTube subtitle processing

When the user uses Helgio with YouTube subtitles, Mintech may process the clicked or selected subtitle text, the surrounding context necessary for translation, the requested translation, saved vocabulary and related technical event data.

The Service is not intended to store or reconstruct full YouTube subtitle tracks, full transcripts, complete videos or browsing history.

6. Purposes and legal bases

We process personal data to create and manage accounts, provide translation, subtitle, document, vocabulary and card-generation features, authenticate users, manage subscriptions and payments, prevent fraud and abuse, enforce fair-use limits, provide support, maintain security, comply with legal, accounting and tax obligations, improve the Service using aggregated or anonymised data, and communicate service-related notices.

7. Third-party processors

We may use payment providers such as Paddle, Stripe, PayPal, Apple and Google; translation and AI providers such as DeepL, OpenAI and Google Translate; document-conversion providers such as Convertio; hosting and infrastructure providers; email and support providers; analytics providers where enabled; and security or logging providers.

8. Retention

Saved vocabulary, cards and learning data are retained while the account exists, unless deleted earlier by the user. Payment records, invoices, tax documentation, fraud-prevention records, security logs and legal-claim records may be retained for legally required or permitted periods.

9. User rights

Depending on applicable law, users may have rights of access, rectification, erasure, restriction, portability, objection, withdrawal of consent and complaint to a supervisory authority. Users may request deletion of their account and data through the Service or by contacting support@mintech.at.

10. Security

Mintech uses technical and organisational measures intended to protect personal data, including access controls, encryption in transit where appropriate, infrastructure security, logging and abuse prevention.
