Privacy Policy
Last updated: 28 August 2026
Raidzer0 LTD (company number 11234967), registered in England and Wales and trading as SlumberPlan ("SlumberPlan", "we", "us", "our"), provides an adult-facing child-sleep support service to parents and carers.
We are the data controller for the personal information described in this policy. This means we are responsible for deciding how and why your personal information is used.
Raidzer0 LTD is registered with the Information Commissioner's Office (ICO), registration number ZC241294.
This Privacy Policy explains what information we collect, why we collect it, how we use and protect it, who we share it with, how long we keep it, and the rights you have under UK data protection law, including the UK General Data Protection Regulation ("UK GDPR") and the Data Protection Act 2018.
If you have any questions about this policy or how we handle your information, contact us at hello@slumberplan.com.
1. Who we are
Raidzer0 LTD
Company number: 11234967
Registered in England and Wales
Trading as: SlumberPlan
Email: hello@slumberplan.com
SlumberPlan is intended for adults. Children cannot create accounts or use the service independently.
2. Information we collect
We collect the following categories of personal information.
Account information
When you create an account, we may collect:
- your name;
- email address;
- mobile phone number;
- account credentials, including a securely hashed password; and
- information needed to manage your subscription.
Your child's information
You may choose to provide information about your child so that we can provide personalised sleep guidance. This may include:
- age or date of birth;
- sleep and wake times;
- nap and bedtime patterns;
- sleep routines;
- night waking information;
- feeding or other routine information where relevant to sleep;
- sleep diary entries;
- information about your child's sleep environment; and
- other information you choose to provide when using the service.
Please only provide information about a child where you are authorised to do so.
Information that may relate to health
Because sleep can be affected by health and wellbeing, you may choose to tell us information about your child's health, development, medication, medical conditions or other circumstances.
Some information of this kind may constitute special category data, including information concerning health under the UK GDPR.
We do not require you to provide medical information in order to use SlumberPlan unless a particular feature specifically tells you otherwise.
Where we process special category data, we will have both an appropriate Article 6 lawful basis and an applicable Article 9 condition under the UK GDPR. Where we rely on consent for special category data, we will ask for explicit consent separately from your general acceptance of this Privacy Policy. You can withdraw that consent at any time.
WhatsApp messages
If you choose to use our WhatsApp support service, we collect and process the messages and information you send to us through WhatsApp.
This may include information about you, your child, your child's sleep, and anything else you choose to tell us in your conversations with SlumberPlan.
We use this information to provide continuous, context-aware support and, where applicable, update your sleep diary and personalised sleep plan.
Payment information
When you subscribe to SlumberPlan, payment is handled by our payment provider.
We do not store your full payment card details. We receive limited billing information and confirmation of payment as necessary to manage your subscription, provide the service and meet our legal and accounting obligations.
Technical information
We may collect basic technical information needed to operate and secure the service, including:
- IP address;
- browser and device information;
- session information;
- essential cookies and similar browser storage;
- security and diagnostic logs; and
- information about errors or technical problems.
We only collect technical information where it is necessary for the relevant purpose.
3. How and why we use your information
We use your information for the following purposes:
Providing SlumberPlan
We use your information to:
- create and manage your account;
- provide your personalised sleep plan;
- maintain your sleep diary;
- respond to your questions;
- provide WhatsApp support;
- personalise our responses to the information you provide;
- manage your subscription; and
- provide customer support.
Our lawful basis for this processing is generally performance of our contract with you.
AI-powered support
SlumberPlan uses artificial intelligence to help analyse the information you provide and generate personalised sleep guidance and responses.
The AI systems we use process information on our behalf for the purposes described in this Privacy Policy.
We do not use AI to make decisions about you that have legal or similarly significant effects on you.
AI-generated guidance is not a medical diagnosis or medical treatment.
SlumberPlan's responses and sleep plans are generated using Anthropic's Claude models via Anthropic's API. If you send a voice note on WhatsApp, it is transcribed using OpenAI's transcription API. Both providers process this information on our behalf under commercial API terms: they do not use information submitted through SlumberPlan to train their models, and they retain inputs and outputs only for a short period (currently up to 30 days) for security and abuse monitoring before deletion, unless law requires otherwise or content is flagged for misuse. Neither provider routinely has humans review conversations; limited review can occur as part of safety and abuse investigation. This processing may take place outside the UK, in which case the safeguards described in section 8 apply. We send AI providers only the information needed to generate your responses, plan and transcriptions, and for no other purpose.
Security and service improvement
We may use personal information and technical information to:
- keep SlumberPlan secure;
- detect and prevent fraud, abuse or misuse;
- investigate technical problems;
- maintain and improve the reliability of the service; and
- understand and improve how our service operates.
Where we rely on legitimate interests, our legitimate interests include operating a secure, reliable and sustainable service and improving the experience we provide, while taking account of your rights and interests.
Legal obligations
We may use and retain information where necessary to comply with legal, regulatory, accounting or other legal obligations.
Marketing
We will only send you electronic marketing where we are legally permitted to do so and, where required, you have provided the appropriate consent.
You can withdraw marketing consent at any time.
Service messages necessary to provide SlumberPlan are different from marketing communications.
4. Special category and health information
SlumberPlan is not a medical service.
You should not use SlumberPlan as a substitute for advice from a doctor, health visitor, pharmacist or other appropriately qualified healthcare professional.
If you provide information about a child's health, development, medical conditions, medication or other health-related circumstances, we may process that information where necessary to provide the service.
Some of this information may be special category data under the UK GDPR and receives additional protection.
Where required, we will rely on an applicable Article 9 condition in addition to our Article 6 lawful basis. Where we rely on explicit consent, we will obtain that consent separately and clearly, and you can withdraw it at any time.
We aim to collect only information that is relevant to providing the service and do not ask you to provide medical information unless it is relevant to the feature or support you are using.
If your child has a medical condition, you should seek appropriate professional medical advice rather than relying on SlumberPlan.
5. Children's information
SlumberPlan is an adult-facing service for parents and carers. It is not intended for use by children, and children cannot create accounts or use the service independently.
We do not knowingly collect personal information directly from children.
Information about a child is provided to us by the adult using SlumberPlan. You should only provide information about a child where you are authorised to do so.
We use information about children to provide the service to the adult using SlumberPlan and for the other purposes described in this Privacy Policy.
We do not sell children's personal information.
You can review, correct or request deletion of information about your child by using the controls available in your account or by contacting us.
6. WhatsApp messaging
If you choose to use SlumberPlan through WhatsApp, your messages are transmitted using WhatsApp, which is operated by Meta.
Our WhatsApp messaging service is provided using Twilio, which processes information on our behalf where applicable.
We may store the content of your WhatsApp conversations so that we can:
- provide continuous and context-aware support;
- understand previous conversations;
- update your sleep diary;
- maintain your personalised sleep plan; and
- provide customer support.
WhatsApp and Meta may process information independently of SlumberPlan, including information relating to the operation and security of their services. Their processing is governed by their own terms and privacy information.
You can stop using WhatsApp support at any time. You can also ask us to delete your WhatsApp conversation history, subject to information we are required or permitted to retain by law.
7. Who we share your information with
We do not sell your personal information.
We share personal information only where necessary to operate SlumberPlan, provide the service, comply with the law, or protect our legitimate interests.
Our service providers may include:
- cloud hosting and database providers, which host the SlumberPlan service and associated data;
- Twilio, for WhatsApp and other messaging services;
- email providers, for account, password and service emails;
- AI providers, which process information submitted to SlumberPlan to generate personalised responses and sleep guidance;
- payment providers, which process payments and billing information; and
- other technical service providers where necessary to operate, secure or support SlumberPlan.
Where a provider processes personal information on our behalf, we require appropriate contractual protections and only authorise processing for the purposes for which the provider is engaged, subject to any processing the provider is legally required to carry out.
Some providers may process information as an independent controller for their own purposes. Where this applies, their own privacy information will also apply.
We may also disclose information:
- where required by law, regulation or legal process;
- where necessary to establish, exercise or defend legal claims;
- to protect the rights, property or safety of SlumberPlan, our users or others; or
- in connection with a sale, restructuring or transfer of all or part of our business, subject to applicable data protection requirements.
8. International transfers
Some of our service providers may process personal information outside the UK.
Where personal information is transferred outside the UK, we will use an appropriate lawful transfer mechanism and safeguards as required by UK data protection law.
Depending on the destination and circumstances, this may include:
- a UK adequacy regulation;
- the UK International Data Transfer Agreement;
- the UK Addendum to the EU Standard Contractual Clauses; or
- another lawful transfer mechanism available under UK data protection law.
Where appropriate, we will also take additional steps to protect personal information transferred internationally.
You can contact us if you would like further information about the safeguards applying to a particular international transfer.
9. How we protect your information
We take appropriate technical and organisational measures to protect your personal information against accidental loss, misuse, unauthorised access, alteration or disclosure.
These measures include, where appropriate:
- encryption of information in transit;
- secure password hashing;
- access controls;
- limiting access to personal information to people and systems that need it;
- security monitoring and logging; and
- appropriate contractual and security requirements for our service providers.
No internet-based service can guarantee complete security, but we continually review and improve our security measures as appropriate.
10. How long we keep your information
We keep personal information only for as long as it is reasonably necessary for the purposes for which it was collected, including to provide the service, maintain your account, resolve disputes, enforce agreements and comply with legal obligations.
Our retention periods are determined by the type of information and the reason we hold it.
In general:
- Account information, sleep plans, sleep diary information and WhatsApp conversation data are retained while your account is active. They remain available if you cancel your subscription so your family can return to SlumberPlan. After we confirm an account-deletion request, we delete this information in full, except for records we are legally required to keep, such as payment and consent records.
- Payment and accounting records are retained for the period required by applicable tax, accounting and other legal obligations.
- Security and technical logs are retained only for as long as reasonably necessary for security, troubleshooting, fraud prevention and service reliability.
- Consent records are retained for as long as necessary to demonstrate and manage the consent you have provided.
When information is no longer required, we will securely delete it or anonymise it.
You can request deletion of your account and personal information at any time. Some information may need to be retained where we have a legal obligation or another lawful reason to do so.
11. Your data protection rights
Under UK data protection law, you may have the right to:
- access the personal information we hold about you;
- correct inaccurate or incomplete information;
- delete your personal information in certain circumstances;
- restrict how we use your personal information in certain circumstances;
- object to certain processing, including processing based on legitimate interests;
- data portability, where applicable, allowing you to receive certain personal information in a structured, commonly used and machine-readable format or ask us to transfer it to another provider; and
- withdraw consent where we rely on consent as our lawful basis.
These rights are subject to certain legal conditions and exceptions, so they will not apply in every circumstance.
If you withdraw consent, this will not affect the lawfulness of processing carried out before you withdrew it.
How to exercise your rights
To exercise your rights, contact:
We may need to verify your identity before completing certain requests.
We will normally respond to a valid request within the time period required by applicable data protection law.
You also have the right to complain to the Information Commissioner's Office (ICO), the UK's data protection regulator.
You can find information about the ICO at:
We would appreciate the opportunity to deal with your concerns first, but you have the right to contact the ICO directly.
12. Cookies and similar technologies
We use cookies and similar browser storage technologies to operate and secure SlumberPlan.
Essential cookies
Some cookies and similar technologies are strictly necessary for the service to work.
These may include:
- sign-in and session cookies that keep you securely logged in;
- security-related storage;
- GAESA, an essential hosting-infrastructure cookie set by our hosting provider's load balancer (Google Frontend) for routing and session affinity, not for analytics or advertising;
- routing or load-balancing technologies used to deliver the service reliably; and
- information needed to remember essential choices you make within the service.
These technologies do not require consent where they are strictly necessary to provide the service you have requested.
Analytics and advertising cookies
Non-essential analytics and advertising technologies will only be used where you have given the required consent.
This may include technologies such as the Meta Pixel if we introduce them in the future.
At the date this policy was last updated, advertising and analytics technologies are not currently active unless separately disclosed through our cookie consent mechanism.
If we introduce non-essential analytics or advertising technologies, they will remain disabled unless you provide the required consent.
You can review, change or withdraw your cookie choices at any time using the Cookie preferences option available in the footer of the website.
Our cookie consent record may be stored in your browser for approximately six months so that we do not ask you to make the same choice on every visit.
The use of non-essential cookies and similar technologies is subject to applicable UK privacy and electronic communications rules. Non-essential cookies require appropriate consent, rather than consent being inferred simply from continued use of the website.
13. Changes to this Privacy Policy
We may update this Privacy Policy from time to time to reflect changes to SlumberPlan, our technology, our service providers, legal requirements or the way we process personal information.
When we make significant changes, we will update the "Last updated" date at the top of this policy and, where appropriate, notify you directly.
We will not introduce a materially different use of your personal information without providing the information required by applicable data protection law.
