App privacy policy

Last updated: 16 October 2026

This privacy policy explains how Onizion Ltd ("Onizion", "we", "us") collects, uses and shares your personal information when you use the Onizion App on iPhone, iPad, Android or the web (the "App"). It applies to users in the UK and around the world, including the United States.

For how we handle information when you shop on onizion.com, see our website privacy policy.

Who we are

Onizion Ltd is a company registered in England and Wales (company number 17056537). We are the data controller for the personal information described in this policy.

Address: 115 Beltinge Road, Herne Bay, CT6 6HS, United Kingdom
Email: info@onizion.com

We are registered with the UK Information Commissioner's Office (ICO). We will publish our registration number here once it has been issued.

The information we collect

Information you give us

Account details: your name, email address and password. If you sign in with Apple or Google, we receive your name and email address from them (Apple lets you hide your email address).
Wellbeing check-ins: information you choose to enter about how you feel, such as mood, stress, relaxation or sleep ratings.
Support messages: anything you send us when you contact us for help.

Information from your device and your bed

Listening history: which soundtracks you play, when, and for how long.
Health and wearable data: if you choose to connect Apple Health, Google Health Connect or a compatible wearable, we read the data you allow, such as heart rate, heart rate variability or sleep data. You choose exactly which types of data to share, and you can turn this off at any time.
Bed connection data: when the App connects to your Onizion sound bed by Bluetooth, we collect the bed's identifier, firmware version, settings and technical status. The App needs Bluetooth permission to do this.
Notification data: if you allow notifications, a device token that lets us send them.
Technical and usage data: your device type, operating system, app version, how you use the App, and crash reports. We collect this using analytics and crash reporting tools.

Information from app stores

Purchases: if you buy an upgrade in the App, Apple or Google processes the payment. We receive confirmation of what you bought, but not your card details.

Wellbeing and health data

Wellbeing check-ins and health or wearable data are sensitive. Under UK and EU law, information about your health is "special category" data and has extra protection. We will:

only collect it if you give your explicit consent in the App, which you can withdraw at any time in the App's settings;
only use it to personalise your sessions and show you your progress;
never use it for advertising or marketing, and never sell it;
never share it with anyone else except the service providers who store it for us, unless you separately agree to take part in research (see below);
follow Apple's and Google's rules for health data, which means we do not use data from Apple Health or Google Health Connect for advertising and do not share it with third parties for that purpose.

Research

We may invite you to take part in research to help us understand the effects of vibroacoustic therapy. Taking part is optional. We will only share information that identifies you with research partners if you give your separate, explicit consent for a specific study, and we will tell you who the research partner is and what they will do with your information. You can withdraw from research at any time.

We may also use anonymised, combined data that cannot identify you (for example, average session lengths across all users) to improve the App and for research and publications.

How we use your information, and our legal reasons

To create and manage your account and provide the App, including your lifetime Standard subscription and any upgrades. Lawful basis: to perform our contract with you.
To connect to and control your bed. Lawful basis: to perform our contract with you.
To personalise your sessions using wellbeing and health data. Lawful basis: your explicit consent.
To send you notifications such as session reminders. Lawful basis: your consent, which you give through your device's notification settings.
To fix problems and improve the App, using analytics and crash reports. Lawful basis: our legitimate interests in making the App work well. Where the law requires consent for analytics, we will ask for it.
To provide customer support. Lawful basis: to perform our contract with you.
To send you marketing emails about Onizion, if you have agreed. Lawful basis: your consent. Marketing never uses your wellbeing or health data.
To keep the App secure and comply with the law. Lawful basis: our legitimate interests and our legal obligations.

Who we share your information with

We do not sell your personal information. We share it only with:

Service providers who help us run the App, such as cloud hosting, analytics, crash reporting, email and push notification providers. They may only use your information to provide their services to us.
Apple and Google, to provide sign-in, in-app purchases, notifications and the health data connections you choose.
Research partners, only if you have given separate, explicit consent for a specific study.
Professional advisers and authorities, where needed for legal reasons or to protect our rights or the safety of others.
A buyer or investor, if our business is sold, merged or restructured.

Where your information is stored

Our service providers may store and process your information in the UK, the European Economic Area or the United States. When we transfer personal information outside the UK or EEA, we make sure it is protected, for example by using the UK International Data Transfer Agreement, the UK Addendum to the EU Standard Contractual Clauses, or by transferring only to countries the UK has confirmed provide adequate protection.

How long we keep your information

Account and App data: for as long as your account is open. If you do not use your account for 3 years, we will email you and then delete it if you do not reply.
Wellbeing and health data: until you delete it, withdraw your consent, or delete your account.
Support messages: 2 years after your last contact with us.
Purchase records: 6 years, as required by UK tax law.
Research data: as set out in the information for each study.
Anonymised data: we may keep this indefinitely, as it cannot identify you.

When you delete your account, we delete your personal information within 30 days. Copies in secure backups are deleted within a further 90 days.

Deleting your account

You can delete your account at any time:

in the App: go to Settings, then Account, then Delete account; or
by email: contact info@onizion.com from the email address linked to your account.

How we protect your information

We use encryption when your information is sent and stored, limit who in our team can access it, and use trusted service providers with strong security. No system is completely secure, but we work hard to protect your information.

Your choices and rights

You can:

turn off health data sharing in the App or in Apple Health or Google Health Connect;
turn off notifications and Bluetooth in your device settings (the App cannot connect to your bed without Bluetooth);
withdraw consent for wellbeing data, research or marketing at any time in the App or by emailing us.

Depending on where you live, you also have rights to access, correct, delete and receive a copy of your information, and to restrict or object to how we use it. To use these rights, email info@onizion.com. We may need to confirm your identity. We will reply within one month, or within the time limit set by the law where you live. We will not treat you differently for using your rights.

US residents: some US states give you additional rights over health and wellbeing data. We do not sell your personal information or use your health data for targeted advertising. You can use an authorised agent to make a request for you.

Children and young people

The App is for people aged 18 and over. Young people aged 13 to 17 may only use the App with the consent of a parent or guardian, who is responsible for their use of it. The App is not for children under 13, and we do not knowingly collect information from them. If you believe a child under 13 has given us information, please contact us and we will delete it.

For users under 18, we turn off non-essential analytics by default and never send them marketing.

Complaints

If you have a concern about how we use your information, please contact us first at info@onizion.com and we will try to resolve it.

You also have the right to complain to the UK Information Commissioner's Office (ICO) at ico.org.uk or by calling 0303 123 1113. If you live in the European Economic Area, you can complain to your local data protection authority. If you live elsewhere, you may be able to contact the relevant authority where you live.

Changes to this policy

We may update this policy from time to time. We will update the date at the top, and if the changes are significant, we will tell you in the App or by email before they take effect.
