Privacy Policy

Last updated: 15 May 2026 Effective from: 15 May 2026


1. Who we are

Superkin is a service operated by Superwild Ltd, a company registered in England and Wales (company number 17138850), registered office: Moy Road Industrial Estate, Taffs Well, Cardiff, Wales, CF15 7QR.

In this policy, "we", "us" and "our" mean Superwild Ltd. "You" means anyone who uses Superkin — whether you're the owner of an account, a team member someone invited, a dog walker, a vet, or a visitor to our website.

We are the data controller for the personal data we process about you.

If you have any questions about this policy or your data, email us at hello@superkin.app.


2. What this policy covers

This policy explains what personal data we collect from you, why we collect it, what we do with it, who we share it with, and what rights you have under UK data protection law (the UK GDPR and the Data Protection Act 2018).

It applies to:

  • Our website at superkin.app
  • The Superkin mobile apps for iOS and Android
  • Our customer support communications

If you're a vet practice signing up to Superkin's veterinary tier in the future, a separate addendum will apply — we'll send you that when the time comes.


3. What we collect, why, and our legal basis

We try to collect only what we need. Here's the full picture.

We don't collect precise location, contact lists, or browse history.

3.5 What we do NOT collect

  • We do not access your camera roll outside what you explicitly attach to a note
  • We do not record audio in the background or while the app is closed
  • We do not collect data about people who are not on a team you're part of
  • We do not buy, sell, or share data with advertising networks
  • We do not collect special category data (race, religion, sexual orientation, etc.) — we ask you not to put any in notes either

4. How we use your data

In plain terms:

  • To run the service — sign you in, store your dog's information, deliver weekly plans, generate vet briefs, etc.
  • To improve the service — see which features work, find bugs, prioritise improvements
  • To contact you — about your account (transactional emails), occasionally about Superkin updates (you can opt out)
  • To comply with the law — for example, responding to lawful requests from authorities

We do not use your data:

  • To train AI models (see Section 5 for what our AI subprocessors do)
  • For advertising
  • To make automated decisions that significantly affect you legally

5. Who we share your data with — our subprocessors

Superkin is built on a small number of trusted services. Each one processes a specific kind of data on our instructions. We have a Data Processing Agreement (DPA) in place with each.

ServiceWhat they processWhere
SupabaseDatabase, authentication, file storageEU (Frankfurt region)
VercelHosting for the website and APIsEU and US edge network
OpenAIVoice transcription via the Whisper APIUS
AnthropicPlan generation via the Claude APIUS
PostHog (EU)Product analyticsEU (Frankfurt region)
SentryError monitoringUS
ResendTransactional email (welcome, magic link, notifications)US
InngestBackground jobs (Sunday plan generation)US
Apple / GoogleApp distribution and push notificationsGlobal

Important about AI subprocessors (OpenAI and Anthropic): voice recordings sent to OpenAI for transcription, and text sent to Anthropic for plan generation, are processed on our behalf and not retained for model training under their commercial API terms. Both companies retain the data for a short period (typically 30 days) for abuse monitoring, then delete.

We don't share your data with anyone else for any other purpose unless we're legally required to (for example, a court order) or you ask us to (for example, when you share a vet brief PDF).

If we engage a new subprocessor, we'll update this list before the change takes effect.


6. International data transfers

Some of our subprocessors (OpenAI, Anthropic, Sentry, Resend, Vercel for edge functions, Apple, Google) are based in the United States or process data globally. When your data goes there, we rely on the UK International Data Transfer Addendum to the EU Standard Contractual Clauses (SCCs) or equivalent UK-approved mechanisms, plus our own technical safeguards (encryption in transit and at rest).

You can request the specific mechanism used for any subprocessor by emailing hello@superkin.app.


7. How long we keep your data

DataRetention
Account dataWhile your account is active, plus 30 days after deletion
Your dog's data and team logsWhile the household is active, plus 30 days after the last member leaves
Voice recordings30 days after transcription, then deleted from our storage
Voice transcriptsSame as the notes they belong to
PhotosWhile the note exists; deleted with the note
Crash reports and analytics events90 days for crashes, 24 months for analytics
Customer support emails2 years
Billing records (once paid tier ships)7 years (UK accounting rules)

If you delete your account, we delete or anonymise your personal data within 30 days, except where we're legally required to keep it longer (for example, billing records).


8. Your rights

Under UK GDPR, you have the right to:

  • Access the personal data we hold about you (right of access)
  • Get a copy in a portable format like CSV (right to data portability)
  • Correct anything inaccurate (right to rectification)
  • Delete your account and personal data (right to erasure / "right to be forgotten")
  • Restrict how we process your data in certain situations
  • Object to processing based on legitimate interest (including analytics)
  • Withdraw consent at any time where we rely on consent
  • Complain to the ICO if you think we've mishandled your data (https://ico.org.uk/concerns/)

To exercise any of these rights, email hello@superkin.app. We respond within 30 days. We won't charge you unless requests are excessive or repeated.


9. How we keep your data secure

  • All data in transit is encrypted with TLS 1.2 or higher
  • All data at rest is encrypted (Supabase, Vercel, our storage buckets)
  • Authentication is by email magic link only — no passwords for you to lose
  • Access to user data by the Superkin team is restricted, logged, and limited to support and engineering needs
  • We use Row-Level Security in Postgres so role boundaries (Owner vs Helper vs Walker vs Vet) are enforced at the database level, not just in app code
  • Voice recordings are stored in a separate bucket with stricter access controls
  • We do not use third-party SDKs that share data with advertising networks
  • We run penetration tests at least annually once we have meaningful user numbers
  • If we discover a personal data breach that's likely to result in risk to your rights, we notify the ICO within 72 hours and you without undue delay

No system is ever fully secure. But these are the standards we hold ourselves to.


10. Cookies and similar technologies

We use a small number of cookies, all functional or analytical:

Cookie / storagePurposeType
Supabase auth sessionKeep you signed inStrictly necessary
superkin_consentRemember your cookie preferencesStrictly necessary
PostHog analytics IDAggregated product analyticsAnalytics (opt-out available)

We do not use marketing or advertising cookies.

EU and UK visitors see a cookie banner on first visit asking for analytics consent. You can change your preferences any time in Settings → Privacy in the app.


11. Children's data

Superkin is for people aged 18 or over. We don't knowingly collect personal data from anyone under 18 as an account holder.

We know children may use the app on a parent's account — for example, helping log walks or feedings. That's the parent's responsibility to supervise. Kid Mode (a simplified, restricted UI for children) is planned for a future release; until then, parents should not give children access to features they shouldn't see (medications, vet briefs, payment info).

If you believe we've collected personal data from a child without their parent's consent, contact us at hello@superkin.app and we'll delete it.


12. Changes to this policy

We may update this policy as the service evolves. Material changes (for example, a new subprocessor, a new category of data, a change to how we use it) will be communicated to active users by email at least 14 days before they take effect. Minor or clarifying changes will be published here with the "Last updated" date refreshed.


13. How to contact us

For anything — privacy questions, rights requests, general support: hello@superkin.app

Postal address: Superwild Ltd Moy Road Industrial Estate Taffs Well Cardiff Wales CF15 7QR

Information Commissioner's Office (ICO): You have the right to complain to the ICO if you're unhappy with how we've handled your data. Their contact details are at https://ico.org.uk/concerns/.


This policy is written in plain English on purpose. If anything's unclear, ask us — we'd rather rewrite it than have you worry.
