Terms of Use

End User License Agreement (EULA) · Multi Currency · Last updated: April 21, 2026 · Version 1.0

Before you continue By downloading, installing, or using Multi Currency, you accept these Terms. If you do not agree, please do not use the App.

1. Parties

This agreement is entered into between you (the end user) and Ingeniería.dev, operated by Chris Flores, with its registered address at Av. Javier Barros Sierra 495, Santa Fe Lomas de Santa Fe Zedec Santa Fé, Álvaro Obregón 01219, Mexico City, CDMX, Mexico. Contact: christian@irack.mx.

2. App description

Multi Currency is an iOS application that lets you convert amounts across multiple currencies simultaneously, with an offline cache, a Home Screen widget, and a built-in calculator. The App is designed for personal use by travelers, freelancers, and anyone who needs frequent currency conversions.

3. License

We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use Multi Currency on iOS devices you own or control, subject to these Terms and to Apple's Standard EULA.

3.1 Restrictions

4. Premium purchases

4.1 Available plans

Multi Currency offers two Premium options through the App Store. You can choose the one that fits you better — both unlock the same Premium features:

Prices may vary by region and local currency according to the Apple App Store catalog. The final price is always shown on the purchase screen inside the App before you confirm.

4.2 Premium benefits

4.3 Billing and renewal

Monthly subscription:

Lifetime one-time purchase:

4.4 How to cancel the monthly subscription

This section only applies to the Monthly Traveler Plan. The Traveler Lifetime one-time purchase has nothing to cancel.

To cancel your monthly subscription at any time:
  1. Open the Settings app on your iPhone
  2. Tap your name at the top
  3. Tap Subscriptions
  4. Select Multi Currency
  5. Tap Cancel Subscription

Direct link: apps.apple.com/account/subscriptions — opens the App Store subscriptions management screen from any device.

You can also cancel from: App Store app → your profile picture → Subscriptions.

Apple's official guide: support.apple.com/en-us/118428.

When you cancel, you keep Premium access until the current billed period ends. After that, the App reverts to the free mode.

4.5 Free trial period

If a free trial is offered for the monthly subscription, it will automatically convert to a paid subscription at the end of the trial, unless you cancel at least 24 hours before it ends. Free trials are available only once per Apple ID. The lifetime purchase does not include a trial — it's a direct one-time payment.

4.6 Refunds

Refund requests for both the monthly subscription and the lifetime purchase are handled directly by Apple, not by the Developer. You can request a refund at reportaproblem.apple.com by signing in with your Apple ID and locating the Multi Currency transaction. Approval is determined solely by Apple's policy.

4.7 Managing your payment method

Your payment method is managed exclusively through your Apple ID. To update your card, billing address, or preferred payment method, go to Settings → [your name] → Payment & Shipping on iPhone, or visit account.apple.com. Apple's guide: support.apple.com/en-us/118429.

4.8 Family Sharing

Both the monthly subscription and the lifetime purchase are compatible with Apple Family Sharing. If the purchaser enables sharing, other members of the Apple Family group get access automatically using their own Apple ID. To set up or manage Family Sharing, go to Settings → [your name] → Family Sharing, or see Apple's guide: support.apple.com/en-us/108380.

4.9 Restore purchases

If you switch devices or reinstall the App, tap Restore Purchases inside the App to recover your Premium access. This is especially relevant for the lifetime purchase — it's how Apple verifies your one-time purchase is still active on your Apple ID. The Restore Purchases button is required by Apple for any app with paid content (App Store Review Guideline 3.1.1).

5. Accounts and authentication

Multi Currency does not require you to create an account or sign up. User identity and subscription entitlement are handled entirely through the device's Apple ID. We do not manage passwords or login credentials.

6. User data

See our Privacy Policy. In short: all your data lives on your device; we do not collect or transmit personal information.

7. Exchange rate accuracy

Important notice The rates shown are indicative, come from public third-party APIs, and may differ from the actual rates offered by banks, exchange offices, or card issuers. Multi Currency is not a financial service and must not be used as the sole basis for investment decisions, commercial transactions, or international money transfers.

The Developer does not guarantee the accuracy, availability, or timeliness of rates supplied by external services.

8. Intellectual property

Multi Currency, its code, design, interface, text, and brand are the property of Ingeniería.dev and are protected by Mexican and international intellectual property laws. These Terms do not transfer any ownership to you — only a license to use the App.

9. Disclaimer of warranties

The App is provided "AS IS" and "AS AVAILABLE", without any express or implied warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not guarantee uninterrupted or error-free operation.

10. Limitation of liability

To the maximum extent permitted by applicable law, the Developer shall not be liable for any indirect, incidental, special, consequential, or punitive damages, nor for financial losses arising from your use of or inability to use the App. The Developer's aggregate liability shall not exceed the amount you have paid for the App during the 12 months preceding the claim.

11. Indemnification

You agree to indemnify and hold the Developer harmless from any claims arising from: (a) your improper use of the App, (b) your violation of these Terms, or (c) your violation of third-party rights.

12. Termination

We may suspend or terminate your license if you breach these Terms. You may terminate this license at any time by uninstalling the App. Any active subscription will continue its cycle under App Store rules until you explicitly cancel it.

13. Changes to the Terms

We may update these Terms from time to time. The current version will always be published at this URL, along with the date of the update. Continued use of the App after an update constitutes your acceptance. Material changes will also be announced inside the App.

14. Relationship with Apple

Apple Inc. is not a party to this agreement and is not responsible for the App or its content. In the event of a conflict between these Terms and Apple's Standard EULA, the terms more restrictive and applicable to Apple under the App Store Review Guidelines shall prevail.

15. Governing law and jurisdiction

These Terms are governed by the laws of the United Mexican States. Any dispute shall be submitted to the competent courts of Mexico City, and both parties expressly waive any other jurisdiction that might otherwise apply based on current or future domicile.

16. Severability

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions shall remain in full force and effect.
