Terms of Service
Last updated: October 8, 2026 · Version 1.2
This page is provided as-is, in plain language, to explain how SunSleuth works. It may be updated as the service grows.
These Terms are an agreement between you and the operator of SunSleuth ("SunSleuth", "we") about the SunSleuth app and website at sunsleuth.com (the "Service"). By using the Service you agree to them.
1. What SunSleuth does
SunSleuth estimates sunlight, shade and solar energy for places you scan or enter. All results are estimates based on models, your phone's sensors and third-party weather data. They can be wrong. Don't rely on them alone for purchases, electrical work, roof or structural decisions, safety-critical or medical uses (for example powering medical equipment), or financial decisions. Talk to a qualified professional.
2. Accounts
You can use parts of the Service without an account. To buy Pro you sign in with a link sent to your email. Keep access to your email secure; you're responsible for activity on your account. You must be at least 13 years old to use the Service.
3. Pro subscription and billing
- SunSleuth is free to use with limited features. Pro Monthly ($1.99 per month) is the only paid plan. It's a subscription that renews automatically every month at the price shown at checkout until you cancel. Cancel anytime in Settings › Manage billing; you keep Pro until the end of the period you paid for.
- There are no one-time purchases. If we ever shut the Service down, renewals stop and you won't be charged again.
- Who sells Pro. Pro is sold through Link, a payment service run by Stripe. Link is the merchant of record (the seller) for the payment: it charges you, collects and pays any sales tax, and sends your receipts. Your statement will show LINK.COM* SUNSLEUTH. SunSleuth still provides the app and Pro features under these Terms.
- We never see or store your full card number. Prices are in US dollars (checkout may show your local currency). The price you see already includes sales tax where it applies; nothing is added on top at checkout.
- We may change prices for future billing periods with at least 30 days' notice. Changes never apply to a period you've already paid for.
- Refunds are covered in the Refund Policy.
4. Your content
Spots, sky scans and settings you create are yours. You let us store and process them only to provide the Service. Camera images used during a scan are processed on your phone and are not uploaded.
5. Acceptable use
Don't misuse the Service: no reverse engineering beyond what the law allows, no automated scraping, no attempts to get around payment or reach other users' data, and nothing unlawful.
6. Third-party services
The Service relies on third parties such as Open-Meteo (weather), Stripe (payments), Supabase (accounts and storage), Cloudflare (hosting and analytics) and an email delivery provider for sign-in links. Their terms may also apply.
Affiliate links. Gear suggestions in the Service link to Amazon and are labeled "Affiliate link". As an Amazon Associate I earn from qualifying purchases. Buying through these links doesn't cost you more. We don't sell those products, don't show their prices, and aren't responsible for them, their sellers, or Amazon's terms. Suggestions are general and aren't a guarantee that a product fits your setup.
7. Provided as-is
THE SERVICE AND ITS ESTIMATES ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, INCLUDING ACCURACY OF ESTIMATES, TO THE EXTENT ALLOWED BY LAW.
8. Limitation of liability
To the extent allowed by law, our total liability for any claim is limited to the amount you paid us in the 12 months before the claim. We're not liable for indirect or consequential losses, including equipment bought based on estimates.
9. Ending the agreement
You can stop using the Service and delete your data anytime. We may suspend accounts that break these Terms.
10. Governing law
These Terms are governed by the laws of the State of South Carolina, USA.
11. Changes
We'll post changes here and update the date above. For material changes we'll let you know in the app or by email.
