Privacy Policy

Last updated June 26, 2026 · Version 1

This Privacy Policy explains how Paweł Rosner (sole proprietor, Poland) — operator of Massive Research Lab ("the Service") — handles personal data. Contact: privacy@myresearchlab.app.

Two roles, kept separate

Researcher data we collect

Participant data (how we minimise it)

The Service is built to keep participant data minimal and hard to re-identify:

You decide what your study asks; you are responsible for the lawful basis and consent for any personal data your study itself collects.

How we use researcher data

To provide, secure, support, and improve the Service, and to communicate with you about it. We do not sell personal data.

Legal bases (GDPR)

Sub-processors

We use the following providers to run the Service. Several AI/integration providers are connected with your own keys and only process data when you choose to use them.

Sub-processor Purpose Location Data accessed
Clerk Authentication USA Email, display name, auth tokens
Neon (PostgreSQL) Database hosting EU/USA Researcher and participant data
Vercel Application hosting USA Request/response data; no direct DB access
Cloudflare R2 Asset storage Global Uploaded images/audio/video, generated audio
Cloudflare CDN Delivery + DDoS protection Global HTTP request metadata (coarse country)
Upstash Redis Rate limiting USA One-way-hashed coarse buckets; never raw IPs
Inngest Background jobs USA Job metadata; study data only as a job requires
OSF (your key) Preregistration USA Study metadata you choose to push
Anthropic (your key) AI text features USA Prompts + content you send per study config
Hume AI (your key, where enabled) Voice/emotion AI USA Content/audio per study config, with consent
Prolific (your key) Recruitment UK Recruitment metadata; opaque participant IDs

International transfers (e.g. to the USA) rely on appropriate safeguards such as the EU Standard Contractual Clauses where required.

Security

HTTPS in transit; database encryption at rest; third-party credentials you connect are encrypted application-side (AES-256-GCM) and never shown back to the browser; strict workspace isolation; rate limiting against abuse.

AI processing

When you use an AI feature, the relevant content is sent to your connected provider under their terms. AI output is non-deterministic and may be inaccurate. We meter usage for cost/abuse control but do not use your content to train models.

Retention

We keep researcher and study data while your account is active and as needed to provide the Service. You can delete studies and your account; we then delete or anonymise associated data within a reasonable period, except where the law requires us to keep it.

Your rights

Under the GDPR you may request access, rectification, erasure, restriction, portability, and may object to certain processing. Email privacy@myresearchlab.app. You also have the right to lodge a complaint with the Polish supervisory authority (UODO — Urząd Ochrony Danych Osobowych) or your local authority.

Children

The Service is for researchers and is not directed at children. Whether your study may include minors is your responsibility as the controller of participant data.

Changes

We may update this policy; material changes update the version + effective date and, where required, prompt re-acknowledgement.
