Terms of Use

Last updated 1 September 2026 · applies to the Just Currency Converter mobile app for iOS and Android, and to this website at justcurrencyconverter.app.

1. Who these terms are with

Just Currency Converter (“the app”) and this website are provided by Mert Ceyhan, an individual developer established in the Netherlands (“we”, “us”). Contact: pushnoteapplication@gmail.com.

2. Agreeing to these terms

By installing or using the app, or by using the converter on this website, you agree to these terms. If you do not agree, do not use them, and delete the app.

3. Who may use it

The app is offered for users aged 13 and over. If you are under the age of majority where you live, you may use it only with the involvement of a parent or guardian, who agrees to these terms on your behalf.

4. What you get

The app is free. There are no accounts, no subscriptions, no in-app purchases and no advertising. We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the app on devices you own or control, for personal or business purposes. We do not sell you the software; we license it.

5. Exchange rates are information, not a quote

This is the important part, so it is stated plainly.

• The figures are mid-market rates — the midpoint between the buying and selling price, the rate at which banks trade with each other.
• It is not the rate you will be given. A bank, card issuer, ATM or bureau de change adds its own margin and fees, so what you actually receive will be less than the figure shown.
• The rates are dated, not live. Central banks publish once a day on their own schedules. Every screen shows the date of the rates it is using; offline, the app keeps showing the last rates it has and marks them as older.
• The figures come from a third party — Frankfurter, which aggregates reference rates published by central banks, principally the European Central Bank. We do not produce them and cannot guarantee their accuracy, completeness, timeliness or availability.

Nothing in the app or on this site is financial, investment, tax, accounting or legal advice, and none of it is an offer or solicitation to exchange currency at any rate. Do not rely on it for a transaction where the exact amount matters — confirm the figure with the party you are actually paying.

6. Provided as is

The app and this website are provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement. We do not warrant that they will be uninterrupted or error-free, or that any rate shown is correct at the moment you look at it.

Nothing in this section limits any right you have as a consumer under the mandatory law of the country where you live, which applies to you whatever this page says.

7. Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, data or goodwill, arising out of or connected with your use of the app or this website — including any loss arising from a rate shown being out of date, incomplete or wrong, or from the app being unavailable.

This limitation does not apply to liability for intent or deliberate recklessness (opzet of bewuste roekeloosheid), to liability for death or personal injury, or to any other liability that cannot be excluded or limited under Dutch or applicable mandatory consumer law.

The app is supplied free of charge. Where liability cannot be excluded, it is limited to the amount you paid for the app, which is nothing, or to the minimum the applicable mandatory law permits, whichever is greater.

8. Acceptable use

Please do not attempt to disrupt or break the app, the website or the rate service; use them to break the law; or redistribute or resell them as your own product. Automated bulk querying of the rates endpoint through the app is not permitted — if you need rate data programmatically, go to Frankfurter directly, on its own terms.

9. Availability and changes to the service

We may change, suspend or discontinue the app or the website, in whole or in part, at any time. Because the service is free, we owe no compensation for doing so. Where a change is significant and we can reasonably give notice, we will do so in the app's release notes.

10. Ownership and third-party components

The app, this website, and their design, name and logo remain the property of their author. These terms grant a licence to use the software, not ownership of it. Third-party components are used under their own licences: rate data from Frankfurter, sourced from the European Central Bank and other central banks and credited in the app as their terms require; icons from Hugeicons under the MIT licence; and the Manrope and IBM Plex Mono typefaces under the SIL Open Font License.

11. App stores

If you installed the app from Google Play or the App Store, that store's own terms apply to the download alongside these terms. The stores did not make the app and are not responsible for it; support questions should come to us at the address in section 1.

Apple-specific terms

For the iOS app, and as Apple requires: these terms are between you and us only, not with Apple. Apple has no obligation to provide any maintenance or support for the app. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price — which is zero; beyond that, Apple has no other warranty obligation whatsoever. We, not Apple, are responsible for any claim relating to the app, including product liability claims, claims that the app fails to conform to a legal requirement, and claims arising under consumer protection or similar legislation, and for the investigation, defence, settlement and discharge of any third-party claim that the app infringes intellectual property rights. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

12. Privacy

What the app and the site collect, why, and how to switch it off is set out in the Privacy Policy, which forms part of these terms.

13. Changes to these terms

These terms may change; the date at the top will change with them, and continuing to use the app or the site after that means you accept the new version. If you do not accept a change, stop using them and delete the app.

14. Termination

You may end this agreement at any time by deleting the app and ceasing to use the site. We may end it if you materially breach these terms. Sections 5 to 7, 10, 15 and 16 survive termination.

15. Governing law and disputes

These terms, and any dispute arising out of them or out of your use of the app or the website, are governed by the law of the Netherlands, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods. Disputes will be submitted to the competent court in the Netherlands.

If you use the app as a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country in which you are habitually resident, and you may also bring proceedings in the courts of that country.

16. General

If any provision of these terms is held unenforceable, the rest remain in force and the unenforceable provision applies to the maximum extent the law allows. Our not enforcing a provision is not a waiver of it. These terms, together with the Privacy Policy, are the entire agreement between you and us about the app and this website.
