Zimplex.AI privacy notice
Version 2 · Last updated 14 September 2026 · Applies to the Guru app (guru.zimplex.ai) and this website (zimplex.ai)
This privacy notice tells you what to expect us to do with your personal information. It is in two parts: the first covers the Guru app, if you have an account; the second covers this website, if you have filled in one of our forms.
Contact details
Zimplex.AI Ltd is the data controller for this website. We are registered in Scotland (company number SC819809), at 5 South Charlotte Street, Edinburgh, Scotland, EH2 4AN, and registered with the Information Commissioner's Office (ICO) as a data controller. You can contact us by email at info@zimplex.ai.
If you use the Guru app
This part applies to teachers with a Guru account at guru.zimplex.ai.
Your account
To give you an account we hold your name, email address, school, professional role and subject, and a record of when you accepted this notice. If you sign in with a school Microsoft or Google account, we receive your name and email address from that provider. Our lawful basis is contract: we cannot provide the service without it. We keep it until you delete your account.
What you create in Guru
Your courses, calendars, teaching plans, notes, reflective journal entries and to-do items are yours. We store them so we can show them back to you. We do not sell them, and we do not use your journal or your to-do notes to improve our products — that exclusion is built into how the system works, not merely promised. Guru holds no pupil records and has no pupil-level features; please avoid typing pupil or colleague names into free-text boxes.
Asking Guru to do things
When you ask Guru to change a plan or answer a question, we record the request and what Guru did with it. We also record which parts of the app you use. We do this for one purpose — improving Guru: seeing where it misreads instructions and where people get stuck, so we can fix it. Identifying details are removed before any of this is reviewed.
Our lawful basis is legitimate interests. It is on by default and can be switched off at any time in Settings, under “Help improve Guru” — that switch is how you exercise your right to object, and we have made it a single click. Turning it off costs you nothing: the app works exactly the same, and we stop both the recording and the usage analytics. We keep these records for 12 months.
If you subscribe to Pro
Payments are handled by Stripe. We do not see or store your card details. We hold a record of your subscription and its status so we know what your account is entitled to. Our lawful basis is contract, and we keep billing records for as long as UK tax and accounting law requires.
Where your data is held
In the United Kingdom. The app and its database run on Amazon Web Services in the London region.
Your rights
You can download everything in your account, and delete your account permanently, from the Settings page at any time — you do not need to ask us. Your other rights, and how to complain, are set out below and apply equally to the app.
If you use this website
This part applies to zimplex.ai — our register-interest and contact forms. It does not apply to the Guru app, which is covered above.

Lawful bases and data protection rights
Under UK data protection law, we must have a “lawful basis” for collecting and using your personal information. There is a list of possible lawful bases in the UK GDPR. You can find out more about lawful bases on the ICO's website.
Which lawful basis we rely on may affect your data protection rights, which are set out in brief below. You can find out more about your data protection rights and the exemptions which may apply on the ICO's website:
- Your right of access — you have the right to ask us for copies of your personal information.
- Your right to rectification — you have the right to ask us to correct or delete personal information you think is inaccurate or incomplete.
- Your right to erasure — you have the right to ask us to delete your personal information.

- Your right to object to processing — you have the right to object to the processing of your personal data.
- Your right to data portability — you have the right to ask that we transfer the personal information you gave us to another organisation, or to you.

Our lawful bases for the collection and use of your data
Our lawful basis for collecting or using personal information for service updates or marketing purposes is consent — we have permission from you after we gave you all the relevant information. You have the right to withdraw your consent at any time.
Our lawful basis for collecting or using personal information to comply with legal requirements is a legal obligation — we have to collect or use your information so we can comply with the law.
Our lawful basis for collecting or using personal information for dealing with queries, complaints or claims is legitimate interests. We use the name, email address and message that a person voluntarily provides through our contact form so that we can respond to their query, complaint or request and give them the help or information they have asked for. This benefits the person, as it allows us to deal with their enquiry properly and promptly, and benefits us by helping us run and improve our service and maintain good relationships with people interested in our product. We only use this information to respond to and resolve the enquiry, and not for any unrelated purpose. Because the person has chosen to contact us and expects a reply, and because we limit our use to what is necessary to answer them, the impact on their privacy is minimal and does not override their interests, rights or freedoms.
Where we get personal information from
Directly from you.
How long we keep information
| Personal information | Why we hold it | How long we keep it |
|---|---|---|
| Register-interest details (name, email, school, role, date submitted) | To contact you about our launch and onboarding | Until you ask to be removed, or until 12 months after launch if you have not gone on to create an account — whichever is sooner. Then deleted or anonymised. |
| Contact-form correspondence (name, email, message) | To respond to and resolve your enquiry | Up to 12 months after the enquiry is resolved, then deleted. |
For more information on how long we store your personal information, or the criteria we use to determine this, please contact us using the details provided above.
Who we share information with
Data processors
Amazon Web Services (AWS) — cloud hosting and infrastructure provider (information technology sector), data hosted in the United Kingdom.
This data processor does the following activities for us: AWS hosts our website and stores the information submitted through our register-interest form in a secure cloud database on our behalf. The data is held in the United Kingdom. AWS only processes this information on our instructions and does not use it for its own purposes.
PostHog — privacy-friendly website analytics provider, processing in the European Union. PostHog measures aggregate site usage (such as pageviews) for us on a cookieless basis. It only processes this information on our instructions and does not use it for its own purposes.
Others we share personal information with

Cookies and analytics
This website does not use any cookies that require your consent. We use a privacy-friendly, cookieless analytics tool (PostHog, in the EU) to understand how many people visit the site and which pages they view, so we can improve it. It does not store cookies or other identifiers on your device, and we do not use it to build a profile of you or to track you across other websites. We do not use advertising cookies.
If this ever changes — for example, if we introduce analytics that rely on cookies — we will ask for your consent first and update this notice.
