Privacy Policy

Last updated: 31 May 2026

Our promise, in one line

The evidence you bring to ChatD4C is yours. We use it only to build your case file and answer your questions — never to train AI models, never to advertise, and never to sell. Each case is cryptographically isolated so only you and the people you invite can ever see it.

1. Who we are

ChatD4C (“ChatD4C”, “we”, “us”) provides a private tool that helps an individual organise and understand their own communications and records in connection with a divorce or other family-law matter. We are the data controller for the account information you give us. For the evidence you upload or connect, you are the controller and we act as your processor — we handle it on your instructions.

2. Information we collect

  • Account data: your name and email address, and authentication identifiers from Google if you sign in with Google.
  • Evidence you provide: emails, messages, chat exports, documents and notes you upload, and — only if you explicitly connect them — data read from accounts you authorise (for example, read-only Gmail look-back).
  • Case settings: the people, jurisdiction and context you enter to focus your reports.
  • Minimal technical logs: security and error logs needed to run the service. We do not use third-party advertising or tracking cookies.

3. How we use your data

We use your data strictly to provide the service:

  • to retrieve, organise and search your own records;
  • to generate the source-cited reports and answers you request;
  • to secure your account and prevent abuse;
  • to contact you about your account or material changes to the service.

We do notuse your evidence to train, fine-tune or improve any machine-learning model — ours or anyone else’s — and we do not sell or rent your data to anyone, ever.

4. AI processing

Reports are generated by sending the relevant excerpts of your evidence to Anthropic’s Claude API. This processing happens only when you ask for a report. Under Anthropic’s commercial terms, API inputs and outputs are not used to train their models. We send only what is needed to answer your question.

5. How we store and protect it

  • Encryption: data is encrypted in transit (TLS) and at rest by our database and hosting providers.
  • Per-case isolation:every record is tagged to a single case and protected by row-level security in the database, so one case can never read another’s data — even through a bug in application code.
  • Access control: only you, and people you explicitly invite to your case, can access your case. Connected-account tokens (e.g. Gmail) are read-only and stored only for your case.

6. Subprocessors

We rely on a small number of vetted providers to run ChatD4C:

  • Vercel — application hosting;
  • Neon — managed PostgreSQL database;
  • Anthropic — AI report generation (no training on your data);
  • Resend — transactional email (sign-in links, invitations);
  • Google — only if you choose Google sign-in or connect Gmail look-back.

7. Your rights and control

You can view, export and permanently delete your data at any time from your account, or by emailing us. Deleting your case removes its evidence from our active systems. Depending on where you live — including the UK and EU (UK GDPR / GDPR) and Canada (PIPEDA) — you also have rights to access, correct, restrict and port your data, and to complain to your data-protection regulator. You can disconnect any connected account, and revoke Gmail access entirely at myaccount.google.com/permissions.

8. A note on legal proceedings

ChatD4C is built for honest, complete disclosure. Please understand that organising your own records here does not make them privileged. Material relevant to your case may be disclosable to a court or the other party through the normal disclosure/discovery process, just as it would be on your own computer or phone. We will only disclose your data to a third party where you direct us to, or where we are legally compelled to and permitted to tell you.

9. Retention

We keep your data for as long as your account is active. If you delete a case or close your account, we delete the associated evidence from production systems promptly and from routine backups within 30 days, except where we must retain limited records to meet a legal obligation.

10. Children

ChatD4C is for adults (18+). It is not directed to children and we do not knowingly collect their data.

11. Changes to this policy

If we make a material change we will update the date above and, where appropriate, notify you by email. Your continued use after a change means you accept the updated policy.
