Your privacy matters. This policy explains clearly and honestly what data FOCAL collects, how it is used, and your rights as a user.
FOCAL does not collect, transmit, or store any personal data. All user activity — including training sessions, vision progress logs, and session history — is stored locally on your device only.
We do not have access to any information you enter or generate within the app. It never leaves your device.
All payments are processed exclusively by the Apple App Store or Google Play Store. We do not collect, process, or have access to any billing information, credit card details, or payment records.
Please refer to Apple's or Google's respective privacy policies for information on how they handle your payment data.
No personal data is shared with any third-party services, analytics platforms, or advertising networks. We do not use tracking, cookies, or any form of behavioural data collection.
FOCAL is a vision training tool designed for general wellness purposes. It is not a medical device and does not diagnose, treat, or cure any eye condition. Any vision-related data you track within the app is stored solely on your device and is never transmitted to FOCAL or any third party.
We encourage you to consult a qualified eye care professional before beginning any vision training programme, particularly if you have a pre-existing eye condition.
This app is intended for users aged 18 and over. We do not knowingly collect any information from minors. If you believe a minor has used this app, please contact us and we will take appropriate action.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with a revised effective date. Continued use of the app after changes constitutes acceptance of the updated policy.
