We retain account data and project data for the lifetime of the account. After account deletion, personal data is anonymized or deleted without undue delay. We retain some data longer where required by law or by our legitimate interest:

7. Your rights (GDPR)

You have the right to access, rectification, erasure, restriction of processing, data portability, objection, and withdrawal of consent. Contact: kontakt@m2planner.com. You also have the right to lodge a complaint with the President of the Personal Data Protection Office (ul. Stawki 2, 00-193 Warsaw, Poland).

8. Security

Passwords are stored as a cryptographic hash (PBKDF2-HMAC-SHA512), connections are encrypted with HTTPS, sessions are secured with JWT tokens (access token valid for 15 minutes), and we apply rate limiting and automatic session renewal.

9. Use of Google user data (Google API Services User Data Policy)

The Google Calendar integration is optional and applies only to architect accounts that connect it themselves. Once connected, we access only the scopes needed to operate consultation booking: reading free/busy times from selected calendars to show available slots; creating and deleting events in a dedicated "M2 Planner" calendar that we create in the architect's account; reading the calendar list during setup; and change notifications to keep availability up to date.

Google Calendar data is used solely to provide the user-facing consultation booking feature. We do not use it for advertising, do not sell it, and do not share it with third parties except as necessary to provide the service or as required by law. Access tokens are encrypted and stored securely; the architect can disconnect at any time, which deletes the tokens and stops synchronization.

M2 Planner's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

10. Changes

We will inform you of material changes through the Service or by email.
