Privacy Policy

1. Who we are

Northn (operated by Northern Node Corp., a Texas corporation) provides a verified-delivery platform: AI-drafted proposals, escrow-funded milestones, delivery evidence, verification, and settlement for professional engagements, plus record-only products (Northn Bench, Northn Study) that seal a record of work without moving money. This policy describes how we handle personal data when you use northn.dev or the Northn platform, or when you communicate with us.

2. What we collect

Account and contact data: name, work email, firm name, and role when you book a walkthrough, create an account, or contact us.

Engagement data: proposals, milestones, acceptance criteria, change orders, approvals, and dispute records created on the platform.

Delivery evidence: activity metadata, deliverable files, reports, and recorded demos that engagement participants choose to attach to milestones. Evidence depth is configured per engagement by the parties themselves.

Payment-related data: amounts, milestone status, and settlement events. Payments and escrow are processed by regulated, licensed financial institutions; Northn does not store full bank credentials or card numbers.

Record-only products: for Northn Bench and Northn Study, the record holds sealed classifications, readings, timestamps, and hashes. Where an AI look at a screen or a sample produces a classification, the classification is sealed and the underlying frame is discarded on the device. Nothing is observed before the person (or, for a minor, a guardian) has consented to exactly what is observed; the consent is itself the first entry in the record.

Site analytics: standard usage data (pages viewed, approximate location, device type) to improve the site.

3. How we use it

To run engagements: creating proposals, holding and releasing milestone funds through regulated financial institutions, generating delivery reports, and resolving disputes.

To operate AI features: drafting documents and reviewing evidence against acceptance criteria. Where firms bring their own AI keys (BYOK), those requests run under the firm's own provider agreement.

We do not sell personal data, and we do not use your client work to train AI models.

4. Sharing

Within an engagement, evidence and reports are visible to the parties the engagement is configured to share them with — your team, your management, or your client, on your settings.

We share data with service providers who help us run the platform (hosting, regulated payment and escrow institutions, analytics), under contracts limiting their use of it. We may disclose data where the law requires it.

Public anchoring: to make records verifiable without trusting Northn, we periodically publish cryptographic digests of the record to a public ledger. Only cryptographic digests are anchored publicly. No content, names, amounts, or media leave the platform.

5. Security & retention

Data is encrypted in transit and at rest. Access is role-based and logged. Engagement records are retained while an account is active and as needed for legal, dispute-resolution, and audit purposes, then deleted or anonymized.

See our Security page for a fuller description of our practices.

6. Your choices

You can request access to, correction of, or deletion of your personal data by emailing hello@northn.dev. Evidence attached to a completed engagement may be retained where necessary to preserve the integrity of the record both parties relied on.

7. Changes & contact

We will post any changes to this policy on this page with an updated effective date. Questions: hello@northn.dev.
