Terms of use

Last updated: 5 October 2026

Bonnie is a free app by appgrid.eu to keep track of shared costs. By using it you agree to these terms.

What Bonnie does

Bonnie records the expenses that you and your group enter and calculates who owes what. It does not move money and is not a payment service. Paying each other back happens outside the app.

Your responsibility

• Check amounts and balances before you pay someone. Calculations depend on what the group members entered and on the exchange rates used.
• Anyone with a group's code can join it and change its data. Share the code only with people you trust.
• Do not enter unlawful content or other people's sensitive personal data.

Exchange rates

Rates are provided by ExchangeRate-API, are updated once a day and are indicative. Your bank may use a different rate; you can change the rate of each expense.

Availability and liability

The app is provided as is, free of charge and without a guarantee that it is always available or free of errors. To the extent permitted by law, appgrid.eu is not liable for damage that results from using the app, including incorrect balances or lost data. Nothing in these terms limits rights you have as a consumer under mandatory law.

Changes

These terms may change. The date at the top shows the latest version.
