Privacy policy
Effective from 5 November 2026.
Who is the data controller
The controller of your personal data is Michał Majewski, who runs MJSNdev. Contact for data matters: kontakt@mjsndev.pl.
What data I collect and why
When you send a message through the contact form or by email, I process your name, email address and the content of your message. I use them only to reply to your enquiry, prepare a quote and, if we decide to work together, carry out the project.
Legal basis (GDPR):
- Art. 6(1)(b): steps taken at your request before entering into a contract (replying to your enquiry, preparing a quote),
- Art. 6(1)(f): legitimate interest in handling correspondence and, if necessary, defending against claims.
Providing your data is voluntary, but without an email address I can't reply to you.
Who receives the data
Form messages are delivered through Resend (Resend, Inc., USA), which processes them on my behalf. Transfers outside the European Economic Area are based on the Standard Contractual Clauses approved by the European Commission. Data may also be stored by the website's hosting provider and my email provider. I never sell or share data for marketing purposes.
How long I keep the data
If we don't start working together, up to 12 months after the last message. If we do, for the duration of the project, and accounting documents for the period required by tax law.
Your rights
You have the right to:
- access your data and receive a copy,
- rectify or erase your data,
- restrict processing,
- object to processing,
- data portability,
- lodge a complaint with a supervisory authority. In Poland, that is the President of the Personal Data Protection Office (uodo.gov.pl).
To exercise these rights, email kontakt@mjsndev.pl. I don't make automated decisions about you or profile your data.
