Privacy Notice

Effective date: 2026-10-20

MING ZHANG (“we”) provides this website and maintains customer accounts, including the free contractor research service. Contact [email protected] or 1968 S. Coast Hwy #5536, Laguna Beach, CA 92651, USA. Account support: [email protected].

This update applies prospectively. Previously accepted terms and purchase receipts continue to govern existing agreements and their rights. This page does not replace those agreements, change a completed purchase, or remove support, privacy, refund, cancellation, receipt, or retained-record access rights.

Data and purposes

• Account and transaction records: account identifiers, verification state, accepted-document versions and hashes, entitlement records, receipts, and limited security events support account access, billing, existing agreements, fraud prevention, and legal recordkeeping.
• Previously submitted records: requests, uploaded files, research or repair records, and exports retained from existing services remain subject to their applicable terms and privacy rights. A change in the proposed service does not authorize reuse for a new purpose.
• Research requests: the repair description and California city or ZIP code you submit, any license numbers you mention, any quote or contract text you paste, and the resulting report are used to run and keep your research. We send CSLB only contractor license numbers, never your name, email, description, or location. To read your request and any quote, we may send that text, and a quote photo or PDF you choose to upload, to Anthropic, PBC; we never send your name or email. Anthropic returns a structured reading (for example the kind of work, any hazard, the place and amounts) or the text of the quote. Under its commercial terms Anthropic does not use this content to train its models, and it deletes it within 30 days unless it must keep it longer to enforce its usage policy or to comply with law. An uploaded file is read and then discarded; we keep only the text you choose to submit. A quick check without an account uses the description, license numbers and quote text you enter only to answer it; we do not save them, and they are not sent to Anthropic.
• Project Guard: if you buy it, the bids and contract text you enter, the payment schedule, the dates and methods of payments you record (never card numbers; card payments are handled by Stripe, Inc.), the names on lien releases and Preliminary Notices you log, and the CSLB readings of your contractor are kept to run your project and your project file. They are deleted when you close your account.
• Correction requests: the email, role, license number, and message you send are used to review and fix our information.
• Support and technical information: messages you send, timestamps, error codes, and limited network/security metadata help us respond, secure the service, and address privacy or billing matters. Do not send passwords or payment-card details.
• Existing AI-service data: request content needed for an enabled service and model/usage metadata may be processed by its disclosed provider. Existing local data and customer-selected provider modes continue under their accepted terms. Contractor research sends request content only to Anthropic, as described above, and not to these providers.

Contractor details in reports come from public CSLB licensing records about businesses and their licenses. We do not sell personal information and do not use sensitive task content for cross-context behavioral advertising.

Storage and retention

Existing billing and tax records are retained for 7 years. Hosted AI inference request content follows the existing 30-day retention statement unless a shorter provider rule or legal hold applies. Durable customer records have separate retention and export rights under previously accepted terms; research reports and correction requests are kept with your account records under the same deletion, export, and backup rules. Local history remains until you delete it or remove the local data. Backups age out under 35 days. We may retain minimal records when law, an unresolved transaction or dispute, or legitimate fraud prevention requires them.

We use safeguards appropriate to the information and service. No security control eliminates every risk. Protect your account, devices, recovery methods, and exported files.

Sharing

Information is shared with disclosed providers only as needed for the service, payments (including Project Guard), authentication, support, security, or legal duties; when you direct a lawful disclosure; or with a successor subject to applicable notice and law. See the provider list. This notice does not authorize sending your details to a repair provider.

Your choices and rights

Contact us for access, correction, deletion, or a portable copy. Existing cancellation, key removal, local export, and retained-record access remain available under accepted terms and applicable law. We verify requests proportionately, respond within applicable deadlines, and do not discriminate for exercising privacy rights.

Where applicable, California privacy rights include knowing the categories, sources, purposes, recipients, and specific pieces of personal information; correction; deletion subject to lawful exceptions; opting out of sale or sharing; and limiting certain uses of sensitive information. We do not sell or share personal information for cross-context behavioral advertising. You may contact us directly or through an authorized representative with legally sufficient authority. Nothing in this notice waives a mandatory privacy right.

Children, changes, and contact

The service is for adults and is not directed to children. Data may be processed where disclosed providers operate, subject to applicable safeguards. Material changes receive notice and renewed consent when required. Previously accepted terms and privacy commitments are not silently replaced.
