Seerena Polski

Privacy policy

Effective from 10 November 2026.

This document explains what personal data we process in the Seerena service (seerena.com), for what purpose, on what legal basis, who we share it with, how long we keep it and what rights you have. The Polish version is the binding one.

1. Data controller

The data controller is Marcin Beck, a private individual running the Seerena service (the service is free and is not run as a registered business). For anything related to personal data write to contact@seerena.com.

2. What data, why and on what basis

DataPurposeLegal basis (GDPR)
Name, email address, password (we store only its cryptographic hash) — or, when you sign in with Google, the name and email address from your Google account Creating and running your account, signing in, confirming your address, resetting your password Art. 6(1)(b) — performance of the service contract
Addresses of the sites you study, study goals, results, screenshots of the studied sites, point balance and history, feedback on results Providing the service: running studies and showing results Art. 6(1)(b)
Where you came from (e.g. the ref parameter of the link that brought you here) Knowing which channels bring users Art. 6(1)(f) — our legitimate interest
IP address, browser, time and address of requests (server logs) Security, limits on sign-in and sign-up attempts, abuse detection, troubleshooting Art. 6(1)(f)
Visit data for the home page collected by Google Analytics (cookies) Visit statistics Art. 6(1)(a) — your consent, which you can withdraw at any time
Content of messages you send us Replying and staying in touch Art. 6(1)(f)

Providing data when you sign up is voluntary, but without it you cannot create an account.

Studied sites. We store screenshots and content of the studied sites as they looked at the time of the study. Only study sites you are entitled to test. If a studied site shows personal data (for example after signing in), you decide to bring it into the study — do not study such pages without a legal basis.

3. Language models

Part of the analysis is done by language models in Google Cloud Vertex AI, called in a European Union region. We pass them what the study needs: screenshots and content of the studied site, the study goal and the description of the simulated user profile. We do not pass them your account data (name, email address). Under the Google Cloud terms this data is not used to train models.

Study results are produced automatically, but we make no decisions about you based on them — they describe the studied site, not the user.

4. Who we share data with

We do not sell data or share it for marketing purposes.

5. Transfers outside the European Economic Area

Resend and Google may process data in the United States. Such transfers rely on the European Commission's adequacy decision for the EU-US Data Privacy Framework or on standard contractual clauses approved by the European Commission.

6. How long we keep data

Google Analytics starts only after you click “I agree”. You can withdraw consent at any time:

8. Your rights

You have the right to access your data, to rectify it, to have it erased, to restrict processing, to data portability and to object to processing based on legitimate interest. You can withdraw consent at any time — this does not affect the lawfulness of processing before the withdrawal. To exercise these rights or delete your account, write to contact@seerena.com from the address linked to the account. We will reply within one month.

You also have the right to lodge a complaint with a supervisory authority — in Poland the President of the Personal Data Protection Office (ul. Stawki 2, 00-193 Warsaw, uodo.gov.pl), or the authority in your country of residence.

9. Security

Connections are encrypted (HTTPS), passwords are stored only as cryptographic hashes, and access to data is limited to people who need it to run the service.

10. Changes to this policy

When we change this policy we will update the date at the top of the page. We will tell registered users about significant changes by email.
