TheoryXP — Your Data & Account Rights

Version: V1.4
Effective date: 24 September 2026
Controller: TheoryXP Limited
Contact: support@theoryxp.app

This page explains the main account controls and data-protection rights available to TheoryXP users. The full Privacy Policy contains the complete privacy information.

In-app controls

Export My Data

Use Export My Data in TheoryXP to create an export of the account/profile and learner information currently included by the backend export function. This in-app export does not limit your separate legal right of access.

Delete Account

Use Delete Account to delete your TheoryXP account and account-linked learner data from active TheoryXP systems, subject to information that must lawfully be retained separately and limited backup/deletion safeguards described in the Privacy Policy.

Deleting the app from your iPhone does not itself delete the server-side account.

Hide History is different

Hide History hides older Practice history from that view. It is not an account-erasure control and does not erase the underlying learning evidence used by the performance system.

Your legal rights

Depending on the processing and lawful basis, you may have rights to:

  • be informed about how your information is used;
  • access your personal information;
  • correct inaccurate personal information;
  • request erasure;
  • request restriction;
  • object to processing based on legitimate interests;
  • receive certain information in a portable format; and
  • withdraw consent where a particular processing activity genuinely relies on consent.

You do not need to quote the UK GDPR, use a particular form or use legal terminology. A clear request made to support@theoryxp.app will be assessed according to what you are asking for.

Response time

Data-protection rights requests are handled without undue delay and within the time limits required by law. Some rights are subject to legal conditions or exceptions.

Your right to object

If TheoryXP relies on legitimate interests for a particular use of your information, you can object by emailing support@theoryxp.app. We will consider the objection under the applicable legal test.

Account inactivity

If there is no recorded account activity for 12 months, the account may become eligible for deletion. Where an email address is available, TheoryXP sends an advance warning and provides at least 30 days before deletion. A Guest account without a linked email address may not receive that warning.

AI Tutor and age-eligibility information — when available

If AI Tutor is enabled, TheoryXP may process limited additional personal information connected with that feature.

This can include:

  • the messages you choose to send to AI Tutor;
  • short-lived recent conversation context needed to answer a follow-up;
  • a minimal AI Tutor eligibility state used to determine whether the feature can be accessed;
  • limited safety/rate-limit metadata; and
  • if you deliberately enable a personalisation option, a minimised learning summary relevant to the request.

TheoryXP does not need to collect your exact date of birth for AI Tutor. The planned design uses Apple's Declared Age Range feature where available and retains only the minimum age-related result reasonably needed for access control.

Access, export and deletion

If TheoryXP stores AI-related account data, it must be included in the appropriate data-rights search and in self-service export/deletion where technically applicable.

The V1 design is not to keep a permanent server-side AI conversation history. Information held only temporarily for a current Tutor session may no longer exist by the time a later access request is made. This does not narrow your legal rights to information TheoryXP still holds.

A stored AI Tutor eligibility state is account-linked personal information and is deleted with the active TheoryXP account unless a separate lawful retention requirement applies.

Challenging an age result

If an age-eligibility result appears wrong or prevents access incorrectly, contact support@theoryxp.app. TheoryXP will not ask for a passport, driving licence or exact date of birth by default merely to deal with an age-related query. Any further verification must be proportionate to the issue.

External AI provider

When AI Tutor is enabled, OpenAI may process the content sent to the AI service on TheoryXP's behalf. OpenAI states that API data is not used to train its models by default unless the customer explicitly opts in. Standard API abuse-monitoring logs may contain prompts/responses and are normally retained for up to 30 days, subject to OpenAI's current data controls and legal/security exceptions.

TheoryXP plans to use provider storage settings that minimise application-state retention, including store: false where supported.

V1.4 change note — 24 September 2026

Added the planned AI Tutor, age-eligibility, provider-retention and rights-handling position without removing the existing account/data-rights information.
