Terms of service
AI Spendbook is a free, independent learning project owned by Vind. These pages are written in plain language to say what you can expect from it. Legal matters: support@vind.company. About this project.
1. About this project
AI Spendbook is an independent learning project, built from scratch to explore how AI usage and AI costs can be tracked and understood. It is the property of Vind (vind.company). It is not a commercial product or a professional service. By using it you agree to these terms.
- Free and non-commercial. Using it costs nothing. We don't charge fees, sell subscriptions, ask for payment details, run ads or sell data, and we make no money from it.
- Original work. It was designed and built independently, from problems the builder ran into with AI costs and from general, widely shared ideas about cost tracking. It is not based on, copied from or connected to any other product or company.
- Not affiliated with any provider. It is not affiliated with, endorsed by or sponsored by Anthropic, OpenAI, Google or any other company it mentions. Their names and logos belong to them and appear only to identify the sources you can connect.
- Still evolving. Features can change without notice, and the service may be paused or shut down. Data stored in it may be deleted when that happens, so keep your own records and don't connect data you can't afford to lose or expose.
- AI answers can be wrong. The AI Analyst and AI usage classification use a language model. Their answers, summaries and labels can be incomplete or wrong, so check them against the dashboard figures and their sources before acting on them.
2. No warranty
The service is provided “as is” and “as available”, without warranties of any kind, express or implied, including accuracy, availability, fitness for a particular purpose and non-infringement.
3. Limitation of liability
To the fullest extent the law allows, Vind and the people who build and run this project are not liable for any loss or damage arising from your use of it or your inability to use it, including lost data, lost profits, incorrect figures or decisions made on them. Because the service is free, any liability that the law does not allow us to exclude is limited to the amount you paid to use it, which is zero. You use it at your own risk.
4. Your account
You are responsible for keeping your credentials safe and for activity in workspaces you administer. Workspace owners decide who has access.
5. Your data
You keep ownership of the data you connect or upload. We process it only to run the service as described in the privacy policy.
6. Acceptable use
- Connect only systems and credentials you're authorized to use.
- Don't upload data you're not permitted to share, such as regulated personal data without a lawful basis.
- Don't attempt to access other workspaces or interfere with the service.
7. Financial figures
Dashboard figures are calculated from the data you connect. Billed amounts come from your providers' billing data. Figures labelled as estimates (costs computed from usage and published prices), forecasts, scenarios and savings recommendations are projections: they depend on the data and prices available and on stated assumptions, so they can differ from what you are actually billed. Your provider invoices are the final record. None of this is financial, investment, tax or accounting advice.
8. Ending use
You can stop using the service and delete your workspace at any time from Settings → Danger zone. That deletes its data.
9. Changes
These terms may change as the project changes. The effective date at the top shows the current version. Continuing to use the service means you accept the version in effect.
10. Owner and legal contact
AI Spendbook is the property of Vind (vind.company). All legal matters, notices and requests about the service, these terms or your data must be sent to Vind at support@vind.company.
