Privacy Policy
Last updated 14 September 2026
Coparity is a shared home for separated parents to plan, talk, share and resolve — organised around what's best for their children. This policy explains what personal data we hold, why, who can see it, and the rights you have over it.
Template — pending legal review. This is a plain-language draft written to be clear and honest about how Coparity works. It is not yet reviewed by a qualified legal or privacy professional and is not legal advice. Wording will be finalised before public launch.
1. Who we are
Coparity (“Coparity”, “we”, “us”) provides the co-parenting coordination platform available at this website and its apps. For the personal data described here, Coparity is the data controller.
Coparity is operated by [Legal entity name], registered at [Registered address]. Questions about this policy or your data can be sent to privacy@coparity.app.
2. The data we collect
Information you give us
- Account details — your name, email address and password (stored only as a secure hash by our authentication provider), and your notification and assistant preferences.
- The shared record you build — everything you add to your co-parenting space: children's details and uploaded documents (such as passports, birth certificates and visas), your residence address, the calendar and custody schedule, trips and time away, activities, shared expenses and their receipts, and messages to your co-parent.
- Your Journal — three private lanes. Moments: notes, check-ins and photos about your children, including how you felt a child seemed and the feeling words you chose. Reflections: your own thoughts and feelings. Evidence: screenshots and notes you keep as a record of what has happened, which can include other people's names and messages.
- Messages to our team — anything you send through “Talk to a human”, including safety concerns.
- Legal coordination — legal contacts you save and any enquiries you draft or send through the Legal tab.
Information we generate or collect automatically
- Activity records — a timeline of changes made in your space (who changed what, and when), so both parents share one clear record.
- AI-assisted insights — signals and suggestions Foresight derives from the data already in your own space.
- Evidence readings — when you add Evidence, AI reads the screenshots to summarise them and flag concerns. If you correct a reading, the original is kept beside the new one, because Evidence is a record.
- Walkthroughs — which “Show me how” walkthroughs you start and where each one ends, so we can pick one back up and mark the ones you've finished. Only you can see this — never your co-parent or anyone acting for you — and we look at it only in aggregate, to find screens that are hard to use. It is deleted with your account.
- Technical data — the essential cookies and session information needed to keep you signed in and secure. See our Cookie Notice.
3. Children's data
Coparity is a tool for parents and guardians, not for children — accounts are held by adults. To do its job, the service necessarily holds information about children that their parents choose to add, such as names, dates of birth, identity documents and schedules.
You provide this information as the child's parent or guardian and are responsible for having the authority to do so. We treat children's data with particular care, apply the same strict access controls described below, and keep it only for as long as your space is active or the law requires.
Journal Moments can record how you felt a child seemed and what they said or drew. We treat them as especially sensitive: only the parent who wrote a moment can see it, no AI reads it, and it is never part of an export.
4. How we use your data
- To provide the service and the features you choose to use.
- To keep both co-parents working from one accurate, shared record.
- To power AI features — Ask AI, Foresight, Tone assistance and Evidence readings — always starting from what is best for your child. These operate only on your own space's data and never share one parent's private information with the other. No AI reads your Journal Moments or Reflections.
- To send service and transactional email (for example, sign-in confirmation, password resets, invitations and notifications you have opted into).
- To keep the service secure, prevent abuse, and meet our legal obligations.
We do not sell your personal data, and we do not use it for third-party advertising.
5. Our legal bases (UK & EU GDPR)
- Contract — to provide the service you sign up for.
- Legitimate interests — to keep the product secure, reliable and improving, balanced against your rights.
- Consent — where we ask for it, such as optional email notifications; you can withdraw it at any time.
- Legal obligation — where we must retain or disclose data to comply with the law.
6. Who can see your data
Access is deliberately narrow. Every record is scoped to your co-parenting space and enforced by database-level row security.
- Shared with your co-parent — the record you build together: children, the calendar and custody schedule, expenses and receipts, trips and time away, activities, chat, and the activity timeline.
- Private to you — your Journal Moments and Reflections, and anything you send our team, including safety concerns. Neither your co-parent nor a legal representative can see them, and they are not added to the shared timeline.
- Private to you and your legal representative — your Evidence, and the legal contacts and enquiries you keep in the Legal tab. Your co-parent cannot see them.
- Legal representatives — a parent can invite a legal representative, who then sees what that parent sees: the shared record, and that parent's own Evidence and legal work. They never see the other parent's Evidence or legal work, or anyone's Moments or Reflections. The parent who invites them chooses whether their co-parent is shown that a representative has been added.
Private here means no one else in Coparity can see it. It does not stop a court ordering disclosure.
Coparity is neutral by design: we give the same child-first guidance to both parents and never secretly relay what one of you tells us to the other.
7. Service providers (subprocessors)
We use a small number of trusted providers to run Coparity. They process data only on our instructions and under data-processing agreements.
| Provider | Purpose |
|---|---|
| Supabase | Database, authentication and file storage |
| Vercel | Hosting for the Coparity website and web app |
| Anthropic | AI assistance (Ask AI, Foresight, Tone and Evidence readings). Inputs are not used to train models under Anthropic's commercial terms. |
| Resend | Transactional and notification email delivery |
| Stripe | Subscription billing and payments. Coparity never sees or stores your full card details. |
A current list of subprocessors is available on request at privacy@coparity.app. We may also disclose data where required by law or to protect someone's safety.
8. International transfers
Where data is processed outside the UK or European Economic Area, we rely on appropriate safeguards — such as the UK International Data Transfer Agreement or the EU Standard Contractual Clauses — so your data keeps an equivalent level of protection.
9. How long we keep it
We keep your data for as long as your space is active. When you delete your account we remove it as described in section 11. Note that a co-parenting space is shared: if a co-parent is still using it, the shared record they rely on is retained, and your past contributions are anonymised rather than removed. Your Journal and Evidence are always deleted with your account, even when a co-parent remains. We may keep limited data longer where the law requires (for example, billing records).
10. Security
- Row-level security so only your space can read your records.
- Encryption of data in transit.
- Private storage for uploaded documents, receipts, Journal photos and Evidence screenshots, reachable only through short-lived, access-checked links.
- Passwords stored only as secure hashes, never in plain text.
11. Your rights
Under UK and EU data protection law you can:
- Access and take your data — export a copy of the records you can see, including your Evidence, at any time from Trust & privacy. Journal Moments and Reflections are never part of an export: you can read them in Coparity at any time, and we will send you a copy of your own entries if you ask at privacy@coparity.app.
- Correct — edit your details and records directly in the app.
- Delete (erasure) — delete your account and personal data from Trust & privacy. If you are the only person in your space, this erases the entire space and its files. If a co-parent remains, we delete your login, your Journal, your Evidence and your other private data, and anonymise your contributions to the shared record, which we keep for them.
- Restrict or object to certain processing, and withdraw consent for anything based on it.
To exercise any right, use the in-app controls or contact privacy@coparity.app. If you are in the UK and think we have mishandled your data, you can complain to the Information Commissioner's Office (ICO) at ico.org.uk; in the EU, to your local supervisory authority.
12. Changes to this policy
We may update this policy as the product evolves. We will change the “last updated” date above and, for material changes, tell you in the app or by email.
