About us
Named after a loyal friend
Zainer was our dog. She was loyal, protective and always in your corner. That's the standard we hold every app to, whether it's ours or yours.
We're a UK company that builds practical software for real problems: court paperwork, property inspections and the everyday jobs that eat up people's time.

Zainer Group website and services
Who we are
This website (zainergroup.co.uk) is run by Zainer Group Ltd, a company registered in England and Wales, company number 16374561. We are registered with the Information Commissioner's Office (ICO), registration number [to add]. For privacy questions or to use your rights, email info@zainergroup.com.
What we collect
- If you contact us, fill in our enquiry form or ask for a quote: your name, email, phone number, business name and the details of your project.
- If you become a client: contract, billing and payment details, and anything you share with us to build your app.
- When you visit the site: our hosting company may keep basic technical records such as your IP address, browser type and visit time, to keep the site secure.
We don't use advertising or tracking cookies on this website. Our pages load fonts from Google Fonts, which means Google may see your IP address.
Why we use it
- To reply to you and prepare a quote (legitimate interests).
- To build and support your app once you've hired us (contract).
- To keep accounts and tax records (legal obligation).
How long we keep it
Enquiries that don't go ahead are deleted after 2 years. Client records and invoices are kept for 6 years after our work ends, as tax law requires.
Who we share it with
We never sell your data. We only share it with companies that help us run the business, such as email, website hosting (which also stores enquiry form messages) and accounting providers. If any of them store data outside the UK, we make sure proper legal safeguards are in place.
Your rights
You can ask us to show you the data we hold about you, correct it, delete it, limit how we use it, object to us using it, or send it to you in a format you can take elsewhere. Email us and we'll reply within one month.
If you're unhappy with how we've handled your data, you can complain to the ICO at ico.org.uk or on 0303 123 1113. We'd appreciate the chance to sort it out first.
Dads In Court
Who we are
Dads In Court (dadsincourt.co.uk) is a trading name of Zainer Group Ltd, registered in England and Wales, company number 16374561, ICO registration number [to add]. For privacy questions or to use your rights, email info@dadsincourt.co.uk.
We are an advice and preparation service. We are not solicitors. This means what you tell us may not be protected by legal privilege in the way it would be with a solicitor.
What we collect
- Your details: name, email, phone number and address.
- Screening questions: your answers before we take your case, including whether you have certain criminal convictions or have been involved in abuse.
- Your case: information about you, the other parent and your children (such as names, ages and current arrangements), plus any court papers, orders and documents you upload.
- Payments: a record of what you've paid and when. Card payments are handled by our payment provider and we never see your full card number.
Some of this is sensitive, such as information about children, health or criminal records. We treat it with extra care and only use it to prepare your case.
Why we use it and our legal reasons
- To provide the service you've paid for (contract).
- To prepare papers for court, which involves sensitive information (establishing or defending legal claims, and your explicit consent).
- To screen applicants, including questions about criminal convictions (your consent, which you give when you fill in the questionnaire).
- To keep payment and tax records (legal obligation).
Information about the other parent and your children is only used to prepare your case. We do not contact them, and we do not send anything to the court or the other side. You file your own papers.
How we keep it safe
Your documents are uploaded through a secure link that we send you after screening. Access is limited to the people working on your case.
How long we keep it
- Case files and uploads: deleted once your finished pack has been sent back to you, and in any case within 7 days.
- If we can't take your case: your questionnaire answers are deleted within 30 days.
- Payment records: kept for 6 years, as tax law requires.
Once your case files are deleted we can't get them back, so keep your own copy of your pack.
Who we share it with
We never sell your data. We only share it with companies that help us run the service, such as our secure hosting, email and payment providers. If any of them store data outside the UK, we make sure proper legal safeguards are in place.
Age
Our service is for adults only. We don't knowingly take cases from anyone under 18.
Your rights
You can ask us to show you the data we hold about you, correct it, delete it, limit how we use it, object to us using it, or send it to you in a format you can take elsewhere. Where we rely on your consent, you can withdraw it at any time, although we may then be unable to carry on with your case. Email us and we'll reply within one month.
If you're unhappy with how we've handled your data, you can complain to the ICO at ico.org.uk or on 0303 123 1113. We'd appreciate the chance to sort it out first.
Landlord Guard app
Who we are
The Landlord Guard app is published by Zainer Group Ltd, registered in England and Wales, company number 16374561, ICO registration number [to add]. For privacy questions or to use your rights, email info@zainergroup.com.
The short version
Your inspections stay on your phone. We don't run a server that stores them, and we can't see them.
What stays on your phone
Everything you put into the app, including property addresses, tenant names, notes, photos and signatures, is saved on your own device only. If you delete the app or lose your phone, that data goes with it, so keep copies of your PDF reports.
Permissions the app asks for
- Camera: to take inspection photos.
- Photos and files: to add existing pictures and to save your PDF reports.
You can turn these off in your phone's settings, but some features won't work without them.
Sending reports
When you send a PDF to a tenant, it goes through the app you choose, such as email or WhatsApp. That app's own privacy policy applies to the sending.
Buying the app
Payment is handled by Apple or Google. They tell us that a sale was made, but they don't give us your card details.
Analytics and tracking
The app doesn't contain advertising, and we don't use it to track you.
Your tenants' data
When you record a tenant's details in the app, you, as the landlord, are responsible for that information. You should tell your tenants how you use their data and keep your reports safe.
Age
The app is meant for adults and is not aimed at anyone under 18.
Your rights
For help using the app, email info@zainergroup.com.
Because we don't hold your inspection data, you're in full control of it on your device. For anything else we may hold, such as emails you send us, you can ask us to show it to you, correct it or delete it. Email us and we'll reply within one month.
If you're unhappy with how we've handled your data, you can complain to the ICO at ico.org.uk or on 0303 123 1113. We'd appreciate the chance to sort it out first.
