About this project
AI Spendbook is an independent, non-commercial learning project built from scratch and owned by Vind (vind.company). It is free: we don't charge, collect payment details, run ads, sell or rent data, or share it for marketing. We keep data only to run the service. It is still evolving, so please don't connect data you can't afford to lose or expose. See the terms for the full notice.
What we collect
- Account data: your email, display name and sign-in provider, through Firebase Authentication.
- Workspace data: AI usage and cost records from the connectors, imports, SDK and API you configure, restricted to the columns and fields you approve.
- Credentials: connector secrets, stored encrypted in a secret manager and never shown back to you.
- Support requests: the subject, message and contact email you send us.
What we don't collect by default
Prompt and completion content is not captured unless a workspace admin turns on content capture in the data policy and the SDK is configured to send it.
How data is used
Only to provide the service: computing analytics, forecasts, budgets and alerts, and answering AI Analyst questions in your workspace. If an admin enables AI classification, request metadata is sent to the configured model provider to assign usage categories.
Retention & deletion
Each workspace has a configurable retention period. Deleting a workspace deletes its tenant data. Disconnecting a connector can optionally delete the data it imported. If the project is paused or shut down, stored data may be deleted.
Sub-processors
The app is hosted on Vercel, and authentication and data storage run on Google Cloud / Firebase. The AI Analyst sends your questions, and any files you attach, to the AI model provider configured for the deployment to produce answers. Emails, when enabled, are sent through Resend. Demo requests and support messages sent from the contact form are delivered through Formspree.
Changes
This policy may change as the project changes. The effective date at the top shows the current version.
