Privacy Policy

Last updated: July 2, 2026

1. Who we are

Seller AI.NASTASIA, operated by Anastasia, based in Warsaw, Poland. Because we operate from Poland (EU), the General Data Protection Regulation (GDPR) applies to how we handle your data.

Contact ai.tester.course@gmail.com

Data controller

Your personal data is controlled by AI.NASTASIA - Anastasia, based in Warsaw, Poland - who created and delivers the course.
Contact: ai.tester.course@gmail.com

Payments are handled separately by Lemon Squeezy, LLC as Merchant of Record: it is the seller of record for the transaction, collects any VAT, and issues your invoice. Lemon Squeezy processes your billing data under its own privacy policy.

Given the nature and scale of our data processing, we are not required to appoint a Data Protection Officer under GDPR Art. 37. For all data protection inquiries, contact ai.tester.course@gmail.com.

We collect only what we need to run the course, process your payment, and provide the AI Mentor experience.

International data transfers

Some providers process data in the United States. The transfer mechanism differs by provider:

Where a provider relies on SCCs we also apply supplementary measures where appropriate. Copies of the relevant safeguards are available on request.

4. AI Mentor and your data

When you ask the AI Mentor a question, your message is sent to the Anthropic Claude API to generate a response. If you send a voice message, it is first transcribed by OpenAI Whisper. If the AI Mentor replies with audio, the text is synthesized into voice by ElevenLabs. These requests are anonymized - no personal data (name, email, payment details) is attached to the API call. Only the text or audio of your question and relevant course context are sent.

Anthropic, OpenAI, and ElevenLabs each operate under their own API data usage policies. As of this writing, none of them use API inputs to train their models by default.

4b. Telegram Mini App

When you use our Telegram Mini App, Telegram provides us with your user ID, first name, and language preference via the WebApp initData. This data is used to personalize your learning experience.

4c. Referral program data

If you join our referral program or use a referral link, we process: your generated referral code, the fact and count of referred purchases, and reward status. If you arrive via a referral link we store a first-party referral code (in localStorage and a 30-day same-site cookie) to attribute your visit; it carries only the referral code, no personal data.

To the person who referred you we show only aggregate counts (visits, conversions, rewards earned). We never reveal to a referrer the identity or email of the people they referred. Referral records are retained for [12 months] after the reward is settled, then anonymized; anti-abuse aggregates may be kept longer in non-identifiable form. Referral attribution and payouts are processed together with Lemon Squeezy (affiliate program). See our Referral Program Terms.

5. Your rights under GDPR

As an EU-based business, we respect your rights under the General Data Protection Regulation. You can exercise any of these by emailing ai.tester.course@gmail.com:

We will respond to any valid request without undue delay and in any event within one month.

6. How long we keep your data

Data type Retention period
Account data (name, email, progress) Active account + 12 months after last activity
Payment records 7 years (legal/tax requirement)
Server logs 14 days
AI Mentor conversations 90 days
Business inquiries (team/B2B leads) 12 months from submission or last contact, then anonymized. Aggregate non-identifiable counts retained for funnel analytics.
DSAR audit log (subject access request records) 3 years (Art. 5(2) accountability evidence)

After retention periods expire, data is permanently deleted or anonymized.

Self-serve data export: available in-app at any time via the "Export my data" button. We send a confirmation link to your registered email; click within 15 minutes to receive a JSON download (valid for 24 hours). Manual rights requests handled within one month via ai.tester.course@gmail.com.

7. Cookies and analytics

Essential cookies. Our web application uses strictly necessary cookies for login sessions and CSRF protection. These do not require consent.

Analytics cookies. With your consent, we use Google Analytics 4 to understand how our pages are used. GA4 sets analytics cookies (for example _ga). We run Google Consent Mode v2 in default-deny mode, so no analytics cookies are set until you accept them in our cookie banner. You can decline, and you can change your choice at any time by clearing site data or using the banner. We do not use advertising or cross-site tracking cookies, and we do not share analytics data with advertising networks.

Referral cookie. If you arrive via a referral link, we store a first-party referral code (in localStorage and a 30-day same-site cookie) solely to attribute your visit to the person who referred you. It carries only the referral code, no personal data.

8. Children

This course is designed for professionals and is not intended for anyone under 16 years old. We do not knowingly collect data from children. If you believe a child under 16 has provided us with personal data, contact us and we will delete it.

9. Complaints

If you believe we are handling your data incorrectly, please contact us first at ai.tester.course@gmail.com - we want to fix it.

You also have the right to lodge a complaint with the Polish Data Protection Authority (UODO):

10. Changes to this policy

If we make significant changes, we will notify you by email. Minor updates (clarifications, formatting) may happen without notice. The "last updated" date at the top always reflects the current version.
