Terms
Terms of service — PrismaFX
Last updated: August 8, 2026
The short agreement between you and the maker of PrismaFX.
What PrismaFX is
PrismaFX is a currency converter and tracker. It shows exchange rates for a wide range of currencies, charts their history, and lets you keep a portfolio, expenses, alerts and widgets on your own device. It is free, and it has no accounts and no purchases.
Exchange rates
This is the section that matters. Exchange rates in PrismaFX come from third-party providers, are indicative, and are not a live trading quote. They can be delayed, served from an earlier cached fetch, or simply wrong. Do not use them as the only basis for a financial decision: for anything that matters, confirm the rate with your bank, broker or exchange. PrismaFX gives no financial, investment or tax advice.
Using the app
PrismaFX is licensed to you for personal, non-commercial use. Please do not reverse engineer it, resell or redistribute it, use it for anything unlawful, or interfere with the services it depends on. Keeping your device and its backups safe is your responsibility: because your data is stored only on the device, it cannot be recovered for you.
Ownership
PrismaFX, its name, its design and its source code belong to Mustafa Evleksiz. Exchange rate data belongs to the providers it comes from and is subject to their own terms. What you create in the app — your portfolio, your expenses, your notes — is yours: it stays on your device, and no rights over it are claimed.
No warranty
The app is provided as-is and as-available, without warranty of any kind. There is no guarantee that rates are accurate, that the providers stay reachable, or that the app is free of errors. To the fullest extent the law allows, the developer is not liable for any loss — financial or otherwise — arising from your use of the app or from relying on the figures it shows. Where local law does not permit such exclusions, they apply only as far as that law allows.
Changes
These terms may be updated as the app changes. The current version always ships inside the app, with its date at the top. Continuing to use PrismaFX after an update means you accept the revised terms.
