Effective date: November 1, 2026
PostLine (the "app," listed on the App Store as "Fence Calculator: PostLine") is made by John Gillespie, an independent developer ("I," "me"). This policy explains, in plain English, what the app does with your information. The short version: the app does not collect your personal data. Everything it uses stays on your iPhone.
The short version
- Fence projects, measurements, and app settings stay on your iPhone. They are stored on the device with SwiftData.
- Material estimates for posts, rails, pickets, gates, concrete, gravel, cost, and stain or paint coverage are calculated on your device.
- A shopping list or PDF materials list, when you create one, is made on your iPhone.
- No accounts, no ads, no analytics, no tracking, and no data is collected by me.
- Nothing is sent to any server by me.
- Purchases are handled by Apple. I never see your payment card details.
- I do not sell your data. I don't have any to sell.
Information stored on your device
Your fence projects, sections, measurements, gates, material choices, saved prices, waste percentage, and app settings are stored locally on your iPhone with SwiftData. A project can describe a wood privacy, picket, chain-link, or vinyl fence, in feet or meters. Without a subscription, the app keeps one saved project. If you use Premium, unlimited projects — including multiple sections, corners, and gates — are stored the same way. I don't operate any servers, and this information is not sent to me or to anyone else.
Estimates for posts, rails, pickets, concrete bags, gravel, cost, and stain or paint coverage are calculated on your iPhone from what you enter. Those calculations are not sent to me.
If your iPhone's iCloud device backup (or another device backup) is turned on, Apple may include this on-device data in that backup, according to your backup settings. I don't receive that backup.
Shopping list and PDF
Premium can build a shopping list and a PDF materials list on your iPhone. Those files are created on your device. I don't receive them. If you save a PDF or share it with another app, that copy is handled by you and by that app.
Purchases
Subscriptions are purchased and processed by Apple through the App Store. Apple handles your payment, and I never receive your payment card information. The app checks with Apple (using Apple's StoreKit) to know whether you have an active subscription. Apple's handling of your purchase is covered by Apple's own privacy policy: https://www.apple.com/legal/privacy/.
No accounts, ads, analytics, or tracking
The app has no sign-up or login. It contains no advertising, no analytics, and no third-party tracking. It does not track you across other apps or websites. Nothing in the app is sent to any server by me. I do not collect, sell, or share your personal information.
Children's privacy
The app is not directed at children under 13, and I do not knowingly collect personal information from anyone, including children under 13. Because the app does not collect personal data, there is nothing to collect from a child either. If you have questions, contact me using the details below.
Your choices and deleting your data
Because your data lives only on your iPhone, you're in control:
- Delete your data by deleting the app. Removing PostLine from your iPhone deletes your fence projects, measurements, saved prices, waste percentage, and settings stored on the device. (If your iPhone backs up to iCloud or a computer, copies may remain in those backups until they're replaced or deleted under your backup settings.)
- Cancel a subscription in your Apple ID settings. Deleting the app does not cancel a subscription.
California residents
PostLine does not collect, sell, or share personal information as those terms are used in California privacy law. If you have a question about your privacy rights, contact me below.
Changes to this policy
If this policy changes, I'll update this page and the effective date above. If a change is significant, such as the app starting to collect new information, I'll update this policy before the change takes effect.
