Privacy Policy

Effective July 26, 2026 · 10X Systems Inc., an Illinois corporation · hello@decidan.ai

The plain-English summary. Decidan is a decision operating system for businesses. Your data exists in Decidan so that your own decisions can be prepared, recorded, and kept on your permanent record. We read your accounting data only with your authorization, we never sell or share your data for advertising, our support staff cannot see your numbers without your explicit time-limited permission, and every access is logged where you can see it. The formal version follows.

1. Who we are

Decidan (https://decidan.ai, application at app.decidan.ai and per-client subdomains) is operated by 10X Systems Inc., an Illinois corporation. This policy covers the Decidan website and application. Where Decidan is provided to you through your accounting firm under a service engagement, your firm’s engagement terms apply in addition to this policy.

2. What we collect

3. What we do not do

4. How we use data

Solely to provide the service: preparing decision briefs and computations for your organization, executing the rules your organization sets, maintaining your record, providing support you request, securing the platform, and meeting legal obligations. Aggregate, de-identified operational statistics (for example uptime or feature usage counts) may be used to improve the product; these never contain your business figures.

5. Subprocessors

We will update this list before adding a subprocessor that can process your business data.

6. Security

Transport encryption (TLS) everywhere; passwords stored as salted PBKDF2 hashes; secrets held in encrypted platform storage; per-organization data isolation; append-only audit records; access controls enforced in software on every request. No security is perfect; we will notify affected organizations without undue delay of any breach affecting their data, consistent with applicable law.

7. Retention and deletion

Business data is retained for the duration of your organization’s use of the service. On termination, or on a verified request from your organization’s Principal, we delete business data within 30 days, except that (a) the organization may first export its record, and (b) minimal records may be retained where law or bona fide audit obligations require it. Disconnecting QuickBooks (see the Disconnect page) revokes our tokens immediately and stops all further reading of accounting data.

8. Your rights

Access, correction, export, and deletion requests go to hello@decidan.ai and are honored for your organization through its Principal. Where privacy law grants you individual rights (for example under applicable U.S. state privacy laws), we honor them within the statutory timelines.

9. Changes

Material changes are announced by email to organization Principals at least 14 days before taking effect. The current version always lives at https://decidan.ai/privacy.
