Terms of Use
Last updated 31 October 2026
These terms apply to the Electryx app for iPhone, iPad and Mac (“Electryx”, “the app”), developed by Andrii Sachok (“we”, “us”). By downloading or using Electryx you agree to them. If you don’t agree, please don’t use the app.
1. Licence
Electryx is licensed to you, not sold, under Apple’s Licensed Application End User License Agreement (the “Standard EULA”). These terms add to the Standard EULA; if they conflict, these terms apply to the extent permitted by Apple’s rules and applicable law. We, not Apple, are responsible for the app and its content.
2. Electryx Pro
Electryx is free to download and use. Electryx Pro unlocks additional design tools, parameter sweeps, advanced analysis and detailed reports. It is available as:
- Electryx Pro Annual — an auto-renewing subscription billed once a year. Eligible new subscribers may receive a one-month free trial.
- Electryx Pro Lifetime — a one-time purchase that does not renew.
Students of Vinnytsia National Technical University (VNTU) who receive a student access link can get Electryx Pro Student for free by opening it and signing in once with their JetIQ account. Student access is a free lifetime licence for personal and educational use. It stays unlocked after graduation and is not re-checked, but it is not transferable, and you must only sign in with your own JetIQ account. We may end the student offer for new sign-ins at any time; access already unlocked is not affected.
Prices are shown in the app and on the App Store in your local currency before you buy. Payment is charged to your Apple Account when you confirm the purchase, or at the end of a free trial.
The annual subscription renews automatically for another year at the then-current price unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the period ends. You can manage or cancel your subscription in your Apple Account settings at any time; cancelling stops future renewals and you keep Pro until the end of the period you’ve paid for. Any unused part of a free trial ends when you buy a subscription.
Purchases are processed by Apple. Refunds are handled by Apple under its policies; we cannot issue them directly. Use Restore Purchases in the app to unlock Pro on your other devices signed in with the same Apple Account. If Pro access ends, your circuits, captures and other data are kept, and all free features continue to work.
3. Educational use and accuracy
Electryx is an educational and design-exploration tool. Its simulation uses simplified mathematical models of real components and cannot reproduce every real-world effect, tolerance or failure mode. Results, calculators, reference data and examples may be incomplete or inaccurate.
Do not rely on Electryx as the only basis for designing, building or repairing equipment, especially mains-powered, high-voltage, high-current, medical, automotive or other safety-critical systems. Always check designs against manufacturer datasheets, applicable standards and real measurements, and follow proper electrical safety practices. Working with electricity can cause injury, fire or death.
4. Your content
Circuits, notes and captures you create belong to you. We don’t claim ownership of them and can’t access them, as described in our Privacy Policy. You are responsible for content you share and for having the right to share it. Bundled examples, lessons, reference material, artwork and the app itself remain our property or that of our licensors.
5. Acceptable use
Don’t use Electryx in violation of any law, attempt to bypass purchase checks, or reverse engineer, copy, resell or redistribute the app or its bundled content except as the law allows.
6. Third-party services and content
Some features use third-party services, including Apple iCloud and the App Store, Google Firebase, and external datasheet and reference websites. Those services are governed by their own terms and policies. We don’t control third-party websites or documents and aren’t responsible for their content, availability or accuracy. Buying Electryx Pro does not grant any licence to third-party content.
7. Changes and availability
We may update, change or remove features, examples or reference content. Specific features or update schedules aren’t guaranteed.
8. Disclaimer and limitation of liability
To the extent permitted by law, Electryx is provided “as is” and “as available”, without warranties of any kind, and we are not liable for indirect, incidental, special or consequential damages, or for loss of data, profits or equipment, arising from your use of the app or reliance on its results. Our total liability for any claim is limited to the amount you paid for Electryx Pro in the 12 months before the claim. Nothing in these terms limits rights you have under consumer law that cannot be excluded.
9. Changes to these terms
We may update these terms. The date at the top shows the latest version. If a change materially affects your rights, we will tell you in the app or its release notes. Continuing to use Electryx after a change means you accept the updated terms.
