Privacy policy
Last updated: 10 November 2026
This policy explains what personal data Zwillinge Ltd ("we", "us") collects through our mobile apps and websites, why, and what choices you have. We aim to collect as little as possible.
Who we are
Zwillinge Ltd is the data controller for our apps and websites. We are a private limited company registered in England and Wales (company number 17177768), registered office 74 Bishops Road, London SW6 7AR, United Kingdom. You can reach us by email at the address shown on our support page.
Our apps
Data you create
Our apps are designed to work without a separate account. Content you create, such as notes, photos, lists or reminders, is stored on your device. If an app offers syncing or sharing, it uses Apple's iCloud (CloudKit) under your own Apple ID. That data sits in your iCloud account, protected by Apple, and we cannot read it. When you share content with other people through an app, they can see what you choose to share with them.
Data we do not collect
- We do not show third-party advertising.
- We do not track you across other companies' apps or websites, and we do not use advertising identifiers.
- We do not sell or rent personal data.
Purchases
In-app purchases and subscriptions are processed by Apple. We receive confirmation that a purchase is valid, but never your payment details, name or address.
Diagnostics
If you agree to share analytics with app developers in your device settings, Apple may give us anonymous crash reports and usage statistics. These help us fix bugs and don't identify you.
Permissions
Some features ask for permission to use your camera, photo library, notifications or similar. We only use these for the feature you are using, and you can change them at any time in your device settings.
App-specific details
Each app's App Store page shows its privacy details. If an app ever needs to process data in a way not covered here, we will describe it in a section for that app below before the change takes effect.
Our websites
Our websites are hosted by Cloudflare. When you visit, Cloudflare processes technical data such as your IP address and browser type to deliver the pages and protect them from attacks. Some of our websites use Cloudflare Web Analytics, which counts visits without cookies and without identifying individual visitors. We do not use advertising cookies.
Some websites contain affiliate links, for example to Amazon. If you click one, the destination site may set its own cookies under its own privacy policy. Where a website has extra features, such as ratings or a newsletter, it explains them in its own privacy notice.
If you email us, we use your email address and message only to reply and to keep a record of the conversation. We delete support emails when they are no longer needed, normally within two years.
Legal basis
Under UK and EU data protection law (UK GDPR and GDPR), we process personal data to provide the app or website you are using (contract), to keep our services secure and working (legitimate interests), and to meet legal obligations. Where we rely on your consent, you can withdraw it at any time.
Service providers and transfers
We use a small number of providers to run our services, mainly Apple (app distribution, iCloud, payments) and Cloudflare (website hosting and email forwarding). They may process data outside the UK, for example in the United States, under appropriate safeguards such as the UK International Data Transfer Addendum or the UK-US Data Bridge.
Children
Our apps are not directed at children under 13, and we do not knowingly collect personal data from children. If you believe a child has sent us personal data, please contact us and we will delete it.
Your rights
You have the right to ask for a copy of your personal data, to have it corrected or deleted, to restrict or object to its processing, and to data portability. To use these rights, email us. To delete data stored in your iCloud, open Settings, tap your name, then iCloud, and manage the app's storage, or simply delete the app's content inside the app.
If you're unhappy with how we handle your data, you can complain to the UK Information Commissioner's Office at ico.org.uk, or to the data protection authority in your country.
Changes
We may update this policy when our apps or websites change. The date at the top shows the latest version. For significant changes, we will let you know in the app or on the website.
