Effective date: November 1, 2026
These Terms of Use ("Terms") apply to the PostLine iPhone app (the "app," listed on the App Store as "Fence Calculator: PostLine"), 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 PostLine. 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. The app, free use, and Premium
PostLine is a fence calculator on your iPhone. It estimates posts, rails, and pickets for a wood privacy, picket, chain-link, or vinyl fence, in feet or meters, and can include a gate.
Without a subscription you can use one straight-run calculator, one gate, and one saved project. Premium is an optional auto-renewing subscription that unlocks unlimited projects with multiple sections, corners, and gates; concrete bags and gravel; a cost estimate with editable prices and a waste percentage; a shopping list and a PDF materials list; and stain or paint coverage. You can keep using the free calculator without subscribing. Subscriptions are offered monthly and yearly through Apple. The monthly plan includes a 1-week free introductory offer for eligible users. The yearly plan has no free trial. The App Store shows the price and what a subscription includes before you buy.
3. Subscription terms
- Plans and prices: The app offers auto-renewing subscriptions:
- Monthly — with a 1-week free introductory offer for eligible users.
- Yearly — with no free 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 your Apple ID settings: iPhone Settings > Apple ID > Subscriptions (Settings > [your name] > Subscriptions). Canceling stops future renewals; you keep your subscription 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 introductory offer for eligible users. Unless you cancel at least 24 hours before the trial ends, it automatically converts to a paid monthly subscription at the monthly price shown in the App Store. 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. An estimate, not a building plan
The app estimates fence materials and cost from the measurements, fence type, and prices you enter on your iPhone. Counts for posts, rails, pickets, and gates, plus concrete, gravel, a shopping list, a PDF materials list, and stain or paint coverage, are planning aids on your device. They are not a site survey or a structural design, and they are not professional fencing, construction, or cost advice. Local codes, terrain, and prices vary. Please check quantities before you buy materials or build, and use your own judgment.
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 materials, 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.
