Effective date: October 18, 2026
These Terms of Use ("Terms") apply to the Plant Light Meter iPhone app (the "app"), made by John Gillespie ("I," "me"). By downloading or using the app, you agree to these Terms. If you don't agree, please don't use the app.
1. Apple's standard license
The app is licensed to you, not sold. Your use of the app is also governed by Apple's Licensed Application End User License Agreement (the "Standard EULA"): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. Apple's Standard EULA applies. These Terms add details specific to Plant Light Meter. If these Terms conflict with the Standard EULA, the Standard EULA controls to the extent of the conflict.
I grant you a personal, non-transferable license to use the app on Apple devices you own or control, as allowed by the App Store's Usage Rules. Please don't copy, modify, reverse-engineer, or redistribute the app except as the law allows.
2. Free and Premium features
The live 0–100 plant fit meter is free for all plants. Premium is an optional subscription that unlocks exact PPFD and DLI readings, saved spots, Plant matchmaker, Light log, and Seasons.
3. Subscription terms
- Plans and prices: Premium is offered as an auto-renewing subscription:
- Premium Monthly — $8.99/month, with a 1-week free introductory offer for eligible new subscribers.
- Premium Yearly — $24.99/year, with no trial.
- Payment: Payment is charged to your Apple ID account when you confirm your purchase (or when a free trial ends, if applicable).
- Auto-renewal: Your subscription renews automatically for the same period and price unless you cancel it at least 24 hours before the end of the current period. Your account will be charged for renewal within the 24 hours before the current period ends.
- Managing and canceling: You can manage or cancel your subscription anytime in iPhone Settings > Apple ID > Subscriptions (Settings > [your name] > Subscriptions). Canceling stops future renewals; you keep Premium until the end of the period you've already paid for. Deleting the app does not cancel a subscription.
- Free trial: The monthly plan includes a 1-week free intro offer for eligible new subscribers. Unless you cancel at least 24 hours before the trial ends, it automatically converts to a paid monthly subscription at $8.99 per month. The yearly plan does not include a free trial.
- Unused trial time: Any unused portion of a free trial is forfeited when you purchase a subscription.
- Refunds: Purchases are processed by Apple. Refund requests are handled by Apple under its policies at https://reportaproblem.apple.com.
- Price changes: If a subscription price changes, Apple will notify you as required and, where required, ask for your consent before charging the new price.
4. Light readings are estimates
The app estimates light from the rear camera's exposure metadata on your device. Readings, including the plant fit meter, PPFD, DLI, Light log, Plant matchmaker, and Seasons, are estimates, not laboratory measurements. They can be affected by your device, camera, angle, surroundings, weather, and other factors. They are meant as a helpful guide, not professional horticultural advice, and they don't guarantee how any plant will grow. Please use your own judgment and consult a qualified expert when it matters.
5. Disclaimers
To the fullest extent permitted by law, the app is provided "as is" and "as available," without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. I don't promise the app will be error-free or always available. As described in the Standard EULA, Apple has no obligation to provide any maintenance or support for the app.
6. Limitation of liability
To the fullest extent permitted by law, I will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of plants, property, data, or profits, arising from your use of or inability to use the app. My total liability for any claim related to the app will not exceed the amount you paid for the app or subscription in the 12 months before the claim. Some places don't allow certain limitations, so some of these may not apply to you.
7. Privacy
The app's Privacy Policy explains how your information is handled.
8. Changes to these Terms
I may update these Terms from time to time. If I do, I'll update this page and the effective date above. Continuing to use the app after a change means you accept the updated Terms.
9. Governing law
These Terms are governed by the laws of the State of California, USA, without regard to its conflict-of-law rules, except where the law of your home country requires otherwise.
