Wobble — Privacy Policy

Last updated: 2 June 2026 Effective: 2 June 2026

Wobble is a baby tracker for tired parents. This policy explains what data we collect when you use the iPhone app, why we collect it, who we share it with, and the rights you have over it. It’s written to be readable. If anything in here isn’t clear, email us at [email protected] and we’ll explain.


The short version


Who we are

Wobble is operated by Wobble Labs UK Ltd (“Wobble”, “we”, “us”), registered at 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom.

For the purposes of the UK GDPR, the EU GDPR, and similar laws, we are the data controller for the data described in this policy. You can reach us at [email protected].


What this policy covers

This policy applies to the Wobble iPhone app distributed via the Apple App Store, and to the backend services that power it. It does not cover websites or services we don’t operate, even if we link to them.


What we collect and why

We’ve kept the categories small on purpose. Here’s the full list.

1. Your account

When you sign up, we ask for your email address and a password so we can identify you across devices and let you share a baby profile with your partner. Authentication is handled by Supabase Auth (see Sub-processors).

We don’t ask for your name, phone number, or postal address.

2. Your baby’s profile

To make the app useful, you give us:

3. Your logs

The records you create as you use the app: feeds, sleeps, diapers, solids, pumping sessions, and medications (for the baby and, optionally, for you). Each log carries the time it happened, the values you entered (volume, duration, etc.), an optional note, and stamps that identify which baby and which parent created or last edited it. These stamps are what make partner sync work — both phones need to know who logged what.

4. Feedback you send us

If you use the in-app Send Feedback form, the text you write reaches us along with your app version and device model. This is purely so we can debug and reply. We don’t use it for anything else.

5. Crash reports

If you opt in to share crash reports with Apple (a system-level choice you make in your iPhone Settings), Apple shares anonymized crash data with us through App Store Connect. We use it to find and fix bugs. We don’t tie it to your account.

What we do NOT collect


About Ask Wobble

When you submit a question through the Ask Wobble AI chat, here’s what happens:

  1. Before the question leaves your phone, an on-device anonymizer strips your baby’s nickname and any contact names you may have typed.
  2. The anonymized question (plus the 14-day log summary that gives the AI context to answer) is transmitted through our Supabase Edge Function to Anthropic (the company behind Claude).
  3. Anthropic processes the question and returns an answer. Anthropic does not store the question or train on its content per their API terms.
  4. The answer is delivered back to your phone and saved to your chat history.

About your baby’s data

You are the parent (or guardian) using the app. All data about your baby is information you choose to enter on their behalf. We never collect data directly from a child. Wobble isn’t designed for use by children and isn’t marketed to children.

We treat the baby’s data with the same care as we treat yours — encrypted in transit, stored on the same access-controlled servers, deletable at any time, never sold, never used for advertising.

If you share a baby profile with a partner, both of you have access to all logs and the baby’s profile. The partner sees what you log; you see what they log. That’s the design.


How we use your data

We use the data above only for these purposes:

We do not use your data for advertising, marketing without your consent, profiling for third parties, or selling to data brokers.


Sub-processors

Wobble runs on top of services provided by other companies who process data on our behalf, under written agreements that bind them to the same privacy commitments. They are not “third parties” who use your data for their own purposes — they’re vendors acting under our control.

Sub-processorWhat they do for usWhere they store data
SupabaseHosts our Postgres database, authentication, real-time sync, and Edge FunctionsIreland (eu-west-1)
AnthropicProcesses Ask Wobble questions and returns answers via the Claude APIUnited States (Anthropic’s processing infrastructure)
AppleDistributes the app, provides TestFlight, and provides opt-in crash reportsApple’s global infrastructure

We list every sub-processor here. If we add one, we’ll update this list and (if material) push an in-app notice before the change takes effect.


Where your data lives

Your data is stored on servers operated by Supabase in Ireland (eu-west-1). If you use Ask Wobble, your anonymized question is transmitted to Anthropic in the United States for processing.

For users outside the EU/UK whose data is transferred into the EU, or for the transfer to Anthropic in the United States, we rely on the appropriate transfer mechanisms (such as Standard Contractual Clauses or the UK International Data Transfer Addendum) to make these transfers lawful.


How long we keep your data


Your rights

Under GDPR, UK GDPR, the California Consumer Privacy Act (CCPA), and similar laws, you have rights over your data. You can exercise any of these by emailing [email protected]:

For California residents: you have the right to know what personal information we collect, to delete it, to correct it, to opt out of any sale or sharing (we don’t sell or share — see the no-sale declaration below), and to be free from discrimination for exercising these rights.

No-sale declaration. Wobble does not sell or share your personal information for cross-context behavioural advertising. We have not done so in the past 12 months and have no plans to.

If you believe we’ve mishandled your data, you can complain to your local data protection authority (in the UK, the Information Commissioner’s Office at ico.org.uk; in the EU, your member-state authority).


Children’s privacy

Wobble is a tool for parents and caregivers, who are adults. We don’t direct the app to children, and we don’t knowingly collect information from a child as a user.

The information you record about your baby is data you voluntarily enter as their parent or guardian. We treat that data with the same care as your own — encrypted in transit, never sold, deletable at any time. If you believe a child has been given access to the app and has created an account themselves, contact us and we’ll close the account.


Security

We protect your data in transit with TLS, and at rest using the encryption mechanisms our infrastructure providers (Supabase) make available. Authentication is via your email and password, stored as a salted hash; we never see your password in clear text. Row-level security policies in our database ensure that only you and partners you’ve explicitly invited can read or write your baby’s data.

No system is perfectly secure. If we ever experience a breach that affects you, we’ll notify you as required by law and tell you what happened, what we did, and what you should do.


Changes to this policy

If we make material changes to this policy, we’ll update the “Last updated” date at the top, and — for changes that meaningfully expand what we collect or how we use it — we’ll push an in-app notice before the change takes effect. Smaller wording changes won’t trigger a notification.

This policy is written in plain English on purpose. If a section feels unclear or you’d like more detail on anything, please ask — we’d rather explain than have you assume.
