Terms

Clear boundaries, in plain language.

These terms describe Marginelle version 1.0 from Trest Line OÜ. Last updated August 21, 2026.

The service

Marginelle performs calculations from values you enter. Results are estimates and may be affected by omitted costs, inaccurate inputs, rounding, actual duration, business conditions, taxes, and other factors.

No professional advice or promised result

The app does not provide market pricing, accounting, tax, payroll, legal, investment, or other professional advice. It does not guarantee profit, income, cost recovery, client demand, or a business result.

Purchases

The optional Lifetime Pro in-app purchase is processed by Apple and subject to Apple’s terms. It supports more than three services up to the technical limit, Menu Change Plans using prices you enter, weekly scenarios, saved audit history and comparison, and CSV/PDF export. Family Sharing is not included in version 1.0.

A purchase, restore, refund, or entitlement change does not delete or hide local audits. Creation limits may apply when Pro access is unavailable.

Your data and exports

You are responsible for entered data and exports you choose to share. Removing the app removes its local working container, subject to Apple-controlled backup behavior. Version 1.0 does not provide whole-library restore.
