Younger users may use the app with parent or guardian consent where required by applicable law.During onboarding, we may ask users to select an age range. The youngest available age range in the current app is 13–17. Lexa is not intended to be targeted specifically at children under 13.If you are under the age of majority where you live, you should use the Services only with the permission of a parent or legal guardian where required by applicable law.We do not knowingly collect personal data from children where doing so would be prohibited by applicable law.

- Legitimate interests: where processing is reasonably necessary for our legitimate interests, provided those interests are not overridden by your rights and freedoms. This includes operating and securing the Services, responding to support issues, preventing misuse, maintaining account integrity, and improving the reliability and quality of the Services.
- Consent: where required, for example if you enable push notifications or where a particular permission or feature requires consent under applicable law. You can withdraw consent where applicable, although this will not affect processing already carried out lawfully before withdrawal.
- Legal obligation: where processing is necessary to comply with legal obligations, regulatory requirements, lawful requests, or recordkeeping duties.


8. Sharing Data and Third-Party ServicesWe do not sell your personal data.We may share personal data only where reasonably necessary to operate the Services, comply with law, or protect our rights. This may include sharing with the following providers:- Firebase Authentication, provided through Firebase/Google, to support account authentication

- Google Sign-In, if you choose to sign in with Google

We encourage you to review the policies of those providers where relevant. This Privacy Policy explains how we handle personal data in connection with the Services.


9. Data Storage Location and International TransfersAccount, onboarding, and learning-progress data stored in Cloud Firestore is currently hosted in London, United Kingdom, using Google Cloud's europe-west2 region.This does not mean that all personal data connected to the Services is stored only in London. Other service-related data processed by Firebase, Google, Apple, TestFlight, authentication providers, or future subscription infrastructure may be processed in other countries according to those providers' infrastructure, terms, and privacy policies.Some of our service providers may process personal data outside the United Kingdom or the country where you are located. As a result, your personal data may be transferred to and processed in jurisdictions that may have different data protection laws.Where applicable, we take steps intended to ensure that personal data transferred internationally is protected by appropriate safeguards required under applicable law.


10. Retention, Account Deletion, and SecurityWe keep personal data only for as long as reasonably necessary for the purposes described in this Privacy Policy, including to provide the Services, maintain account functionality, comply with legal obligations, resolve disputes, enforce agreements, and protect against fraud or misuse.You can delete your account from within the app. If you delete your account, we will delete or anonymise personal data associated with your account from our active systems within a reasonable period, except where we need to retain certain information for legitimate operational reasons, security purposes, fraud prevention, backup processes, dispute resolution, or legal compliance.Because some information may remain temporarily in backups or secure archives, immediate deletion from every system may not always be technically possible. Where that happens, we will limit further use of the retained information and delete it in line with our normal backup and retention practices.If subscriptions or paid features are enabled in the future, subscription and transaction-related records may be retained for longer where required by platform providers, applicable law, accounting rules, tax rules, or financial reporting obligations.We use reasonable technical and organisational measures designed to protect personal data against unauthorised access, loss, misuse, alteration, or disclosure. However, no system can be guaranteed to be completely secure, and we cannot guarantee absolute security. You are responsible for maintaining the confidentiality of your login credentials and for using the Services in a secure manner.


11. External LinksThe app may link to external pages, including our Privacy Policy and Terms and Conditions. These external pages may open in a browser or system web view. External websites and platforms may have their own privacy practices, and we are not responsible for their content or privacy practices.
