LM Technologies AS ("we", "us"), org. no. 938 021 325, operates CalcHub. This page explains what data we collect, why, and what rights you have over it under the GDPR.
What we collect, and why
| Data | Why | Kept when you delete your account? |

| Email, first/last name | Login, account communication | No — anonymized |
| Company, job title, phone | Support context (optional fields) | No |
| Unit system, timezone | Display preferences | No |
| Terms/privacy acceptance timestamp | Legal record of consent | Yes — kept for compliance |
| Marketing opt-in | Only if you explicitly opt in; off by default | No — reset to opted out |
| Saved assessment inputs (thickness, pressure, temperature, etc.) | The calculations you run and save | No — deleted with your account |
| Stripe customer/payment identifiers | Payment processing and accounting records | Payment identifiers are retained for accounting/tax purposes; the rest of the account is deleted |
Assessment input values themselves (wall thickness, pressure, material grade, and similar) are technical, equipment-related data, not personal data.
