Terms
Plain-language terms for using ThatOne.App: free, provided as is, for information rather than advice, and your data stays yours.
Last updated .
Free to use
ThatOne.App is free. There are no accounts, no subscriptions and no paid tiers. Use any tool as often as you like, for yourself or for work.
Provided as is
The tools are offered as they are, without warranty of any kind. We work to keep them accurate and available, but we cannot promise they always will be, and we are not liable for losses that come from relying on them.
Information, not advice
The calculators and trackers here are for information and planning. The money tools are not financial advice, the health tools are not medical advice, and nothing here is legal advice. Figures are estimates based on what you enter and on general formulas; they do not know your situation. For decisions that matter, check with a professional who does.
Your data is yours
Anything you enter stays on your device and belongs to you. You can export or delete it at any time. We claim no rights over it and we do not collect it. The privacy page explains the one exception, tracked QR links, and what they store.
Fair use
Do not use a tracked QR link to send people somewhere harmful or misleading. We may remove links that do.
Changes
If these terms change, the date at the top changes with them.
