Terms of Use

Effective date: 8 September 2026

Please read these terms before using CapDex. They form an agreement between you and us.

1. Acceptance of Terms

By downloading, signing in to, or using CapDex (the “App”), you agree to be bound by these Terms of Use. If you do not agree, please do not use the App.

You must be able to form a binding contract in your country of residence to use the App. If you are a minor, use the App only with the involvement of a parent or guardian.

2. Description of the Service

CapDex helps you learn vocabulary in a new language from the objects around you. You photograph an object; the App isolates it on your device, then sends the picture to an AI vision model that names the object in the language you are learning and in your own. The result is saved as a flashcard and scheduled for spaced repetition review.

Recognition and translation are produced by an automated system. They can be wrong, incomplete, or unsuitable for a given context. The App is a study aid, not an authoritative dictionary or translation service.

3. Your Account

An account is required. You sign in with Apple or with Google — there is no email-and-password option and no guest mode, because every card you make is stored under your account so it stays available across your devices.

You are responsible for keeping access to your Apple or Google account secure, and for activity that takes place under your CapDex account. You may delete your account at any time from the profile screen in the App. That is final — the account is closed and cannot be signed in to again. To have its contents erased as well, write to us; the Privacy Policy sets out what is held and what happens to it.

We may suspend or terminate an account that breaches these terms, or where we are required to do so by law.

4. Free Use, Subscriptions and Payments

• New accounts include a limited lifetime allowance of free captures. Once that allowance is used, continued capturing requires a paid subscription.
• Subscriptions are sold through the Apple App Store. Payment is charged to your Apple ID at confirmation of purchase.
• Subscriptions renew automatically unless auto-renew is switched off at least 24 hours before the end of the current period. Your Apple ID is charged for renewal within 24 hours before the period ends.
• You can manage or cancel a subscription in your device’s Settings under your Apple ID. Cancelling stops future renewals; it does not shorten the period you have already paid for.
• Refunds are handled by Apple under the App Store terms, not by us. We cannot issue App Store refunds directly.
• Prices may change. Where a change affects a renewal, Apple notifies you, and the change applies only to periods after you accept it.

5. Acceptable Use

You agree not to:

• use the App for any unlawful purpose, or to capture images you have no right to capture;
• photograph other people without their consent, or upload content that is abusive, obscene, hateful, or infringes anyone’s rights;
• reverse-engineer, decompile, or attempt to extract the source code or credentials of the App or its backend;
• use automated means to create accounts, generate captures, or otherwise consume the service beyond normal personal use;
• resell, sublicense, or commercially exploit the App or its output without our written permission;
• interfere with the App’s security, probe its infrastructure, or attempt to circumvent usage limits or payment.

We may restrict or end access where these rules are broken.

6. Your Content

The photographs you capture and the words and collections you create remain yours. To run the service, you grant us a limited, non-exclusive licence to store, process and display that content back to you — for example to keep your cards in sync across your devices, and to send a picture to our recognition provider so the object can be named.

This licence exists only so the App can work for you. We do not use your pictures for advertising, and we do not sell them.

You are responsible for having the right to capture and upload what you upload.

7. Privacy

Our handling of your data is described in the Privacy Policy, which forms part of these terms.

8. Disclaimers

The App is provided “as is” and “as available”, without warranties of any kind, express or implied. In particular, we do not warrant that:

• object recognition, translation, pronunciation or example sentences will be accurate or free of error;
• the App will be uninterrupted, secure, or free of defects;
• third-party services the App depends on — Apple, Google, our AI provider, or the App Store — will remain available.

To the fullest extent permitted by law, we are not liable for indirect, incidental, special or consequential damages, or for loss of data, arising from your use of the App. Nothing in these terms limits liability that cannot lawfully be limited.

9. Governing Law and Disputes

These terms are governed by the laws of the country in which you reside, and nothing here removes consumer rights you have under those laws.

If a dispute arises, please contact us first — we will try in good faith to resolve it directly. Only if that fails should either side turn to the courts.

10. Changes to These Terms

We may update these terms as the App changes. Significant changes are announced in the App, and the effective date above is updated. Continuing to use the App after a change means you accept the revised terms.
