This is a budgeting tool and a set of guides. It is not financial advice.

Not financial advice

Everything on this website and in the Under the Mark app is general information for educational purposes. It is not financial, investment, tax, legal or accounting advice, and it does not take account of your circumstances, your income, your obligations or your goals.

We are software builders, not licensed financial advisers, and we are not regulated by any financial authority. Before making a decision that affects your finances, speak to a qualified professional in your own country.

Prices and third-party services

Our guides and the app's cheaper-options feature list prices for third-party services. These are starting figures gathered at a point in time. Prices change frequently, differ by country, and vary with promotions and existing contracts.

Always check the provider's own pricing page before cancelling, switching or signing up for anything. We are not responsible for a decision made on a figure that has since changed.

Accuracy of calculations

The app does arithmetic on figures you enter. If those figures are wrong or incomplete, the totals will be too. It is a planning aid, not a substitute for your bank statement or your accountant. Always reconcile against your actual statements.

Automatic detection

The Chrome extension attempts to identify purchase totals on order confirmation pages. This is a best-effort guess and it is sometimes wrong, which is why nothing is ever saved without your confirmation. Check the figure before accepting it.

Affiliate relationships

Some outbound links to alternative services may earn us a commission at no additional cost to you. This never determines what we recommend or the order we list options in. Many of the alternatives we suggest most often are free and earn us nothing.

External links

We link to third-party sites for your convenience. We do not control them and are not responsible for their content, accuracy, products or privacy practices.

Your responsibility

You are responsible for decisions you make about your own money, and for keeping backups of anything you enter into the app. Because your data never leaves your device, we cannot recover it if it is lost.
