Privacy Policy.

This Privacy Policy describes how Hardseal collects, uses, and protects information when you visit hardseal.ai or interact with us by email. Hardseal's design philosophy is to collect as little data as possible. This page reflects that.

What we don't do. Hardseal does not run third-party ad networks, retargeting pixels, behavioral profilers, or session-replay scripts. We do not sell or rent personal information. We do not use your data to train any machine-learning model. We do not transmit Customer Data outside Customer-controlled environments unless you explicitly authorize it.

1. Information We Collect

SourceDataWhy
Email correspondence (rico@hardseal.ai)Name, email, organization, message contentsRespond to your inquiry, schedule calls, scope engagements
Browser verifier (verify.html)Nothing leaves your browser. Verification runs entirely client-side.By design — independence is the product
Static page hosting (GitHub Pages)Standard server logs (IP, user agent, request path) maintained by GitHub per their privacy policyRequired by the hosting provider for security and abuse prevention
Downloads (trophy case bundle, verifier)Same standard server logs as above. We do not register or track downloaders.Hosting provider operational logs only
Paid Services (Hardseal Core / Edge)Customer contact info, billing info via Stripe (we do not store full card numbers), Customer Data per executed SOWDeliver the contracted Services; governed by the MSA and DPA

2. What We Use Information For

We use the limited information we collect to:

3. Browser Verifier — Zero Data Transmission

The verifier at hardseal.ai/verify.html performs all computation in your browser. The packet you paste into the verifier is never transmitted to Hardseal, GitHub Pages logs do not capture it (it is not sent over the network), and no analytics script observes it. This is an architectural property, not a policy promise — the JavaScript source is readable from the page.

4. Cookies and Tracking

The Site does not set first-party tracking cookies. We do not use Google Analytics, Mixpanel, Segment, Amplitude, Hotjar, FullStory, or similar analytics platforms. The Site may set strictly necessary cookies if Hardseal later adds login or self-serve checkout functionality; if and when that happens, this Policy will be updated and a cookie banner will be shown.

5. Customer Data (Paid Services)

When you engage Hardseal under an MSA / SOW, the handling of Customer Data — including any Controlled Unclassified Information (CUI) — is governed by the executed agreement and the Data Processing Addendum (DPA). Customer Data remains your property. Hardseal Edge and Hardseal Core are designed to operate entirely on your enclave; no Customer Data transmits outside your environment unless you expressly authorize it.

6. Sharing

We share information only with:

We do not sell, rent, or trade personal information to third parties.

7. Data Retention

We retain email correspondence and prospect-engagement records for up to 24 months after the last interaction, after which we delete or anonymize them, except where longer retention is required by law or by an active or recently terminated MSA. Customer Data retention is governed by the applicable SOW and DPA.

8. Your Rights

Depending on your jurisdiction, you may have rights to access, correct, delete, or port your personal information, and to object to or restrict certain processing. To exercise these rights, email rico@hardseal.ai with the subject line "Privacy request."

9. Children

The Site and Services are not directed to children under 16. We do not knowingly collect personal information from children.

10. International Users

The Site is operated from the United States. By using the Site, you consent to the processing of your information in the U.S. We do not currently offer Services to or from EU/UK markets; if and when we do, this Policy will be updated to address GDPR/UK-GDPR terms.

11. Security

We apply reasonable administrative, technical, and physical safeguards designed to protect personal information against unauthorized access, alteration, disclosure, or destruction. No internet transmission or storage is 100% secure; we encourage you to use strong passwords and to be cautious about the information you share by email.

12. Changes

We may update this Privacy Policy. Material changes will be posted on this page with an updated "Last Updated" date.
