The storage periods, steps and thawing methods in the App are guidelines that assume a typical household freezer (around −18°C / 0°F). They vary with the freezer's performance, how often it is opened and closed, and the freshness and condition of the food.
Always check for yourself whether food is actually safe to eat. If you notice anything unusual in its smell, appearance or taste, do not eat it, even if it is still within the period listed. The developer cannot accept responsibility for any damage arising from use of the information in the App.
The App is provided “as is.” The developer does not guarantee that the App will always be available or that it is free of errors. The developer cannot accept responsibility for any damage arising from use of the App.
If these terms change, this page will be updated and the last-updated date will be revised.
