Legal
Terms of Service
Last updated: 19 May 2026
1. Acceptance
By downloading, installing, or using Solar Setup Calculator (“the App”), you agree to these terms. If you do not agree, please don't use the App. These terms are kept deliberately short and plain — this is a small one-person app, not a service with a legal department.
2. The service
The App is an off-grid solar sizing tool. It takes your inputs — appliances, region, days of backup — and produces an estimate of the panels, battery, and inverter you'd need, plus a rough cost and payback figure. It is a planning aid, not an engineering design or a guarantee of any particular result. You are responsible for verifying any system before you buy or install it, and for following local electrical codes and safety requirements, ideally with a qualified installer.
3. Accounts
Accounts are optional. The App works fully without one. If you want to sync your setups across devices you can sign in with Apple, Google, or an email magic link — there is no password. You're responsible for keeping access to whichever sign-in method you choose. You may delete your account at any time from the Profile screen, or by email; see Delete your account.
4. Purchases
The App is free to use. An optional one-time in-app purchase (“Pro”, $6.99 or the local equivalent) unlocks PDF export and the side-by-side comparison view. It is a lifetime unlock, not a subscription, tied to the App Store or Google Play account that bought it.
The purchase is processed by Apple App Store or Google Play, not by us directly. Refunds are handled under Apple's or Google's refund policies — we cannot process refunds ourselves, but we're happy to help you get to the right place; just contact us.
5. Acceptable use
Please don't: attempt to circumvent or tamper with the in-app purchase, reverse-engineer or decompile the App except where that right can't be excluded by law, or abuse the cloud sync service (for example, automated bulk requests or attempts to store data unrelated to the App's purpose). We may suspend access that threatens the service or other users.
6. Disclaimers
The App is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any implied warranty of merchantability or fitness for a particular purpose. The calculator is an estimation tool, not a professional engineering recommendation. Do not rely on it for safety-critical decisions. Sun-hour figures, cost estimates, and payback periods are approximations and will differ from real-world conditions.
7. Limitation of liability
To the maximum extent permitted by applicable law, our total liability arising out of or relating to the App is limited to the amount you actually paid for the Pro unlock (in Austria, €10). We are not liable for indirect, incidental, or consequential damages, or for losses arising from your reliance on the App's estimates. Nothing in these terms limits liability that cannot be limited under Austrian law (for example, for gross negligence or personal injury).
8. Governing law
These terms are governed by the laws of Austria, excluding its conflict-of-law rules. To the extent permitted by law, the competent courts of Innsbruck, Austria have jurisdiction over any dispute. Mandatory consumer-protection rights in your country of residence are not affected.
9. Changes
We may update these terms from time to time — for example, when a feature or a payment detail changes. The “Last updated” date at the top of this page will change when we do. Continuing to use the App after an update means you accept the revised terms.
10. Contact
