YardageKit (“we,” “us,” or “the App”) helps you size a concrete order and follow the pour through Day 1 / 3 / 7 / 28 curing on your device. This Privacy Policy explains what information the App handles, how optional measurement data may be used, and what the App does not do.

By using YardageKit, you agree to this Policy.

1. Our approach

YardageKit keeps your pour planning data on your phone.

In the App, this Privacy Policy may be opened in an in-app WebView (an embedded browser screen). Loading this page may use a network connection to fetch the hosted policy text from our web host. Viewing the policy does not upload your pour tickets to a YardageKit server.

Separately, the App may use the network for install measurement, marketing attribution, and to open certain linked pages you choose to view. Those uses are described below.

2. Information stored on your device

Depending on how you use the App, YardageKit may save the following locally on your device:

• Pour / job details you enter (such as job name, dimensions, shape, calculated yardage or bag estimates, waste settings, and multi-piece rollups)

• Saved pour tickets and recent job history

• Curing checklist progress for Day 1 / 3 / 7 / 28 and related timestamps

• App settings you choose (such as default units and waste percentage)

• Whether you have seen the welcome notice

• Optional curing reminder schedules tied to a pour

• A random on-device mark used only to support App measurement requests

This pour-related information is used to provide the App’s features: order sizing, saved jobs, the pour timeline, and optional reminders.

3. Notifications

If you opt in, YardageKit can schedule local notifications on your device (for example morning nudges on curing milestone days).

• Reminders are scheduled and delivered by your device’s notification system.

• You may see a system permission prompt.

• You can deny permission, disable notifications in system Settings, or turn reminders off in the App.

• We do not send marketing push messages from a YardageKit server.

4. App Tracking Transparency and advertising identifiers

On iOS, the App may ask for permission through Apple’s App Tracking Transparency prompt before reading the Identifier for Advertisers (IDFA).

• If you allow tracking, the App may read your IDFA to measure app installs and attribute marketing campaigns for YardageKit.

• If you deny tracking, or have not granted permission, the App does not use IDFA for that purpose.

• The App may also use other on-device identifiers available through Apple / Adjust for measurement, such as Identifier for Vendor (IDFV) and an Adjust device identifier (ADID), together with the App’s package name.

• You can change tracking permission later in iOS Settings → Privacy & Security → Tracking.

The App’s tracking-permission message explains that the identifier is used to measure app installs and attribute marketing campaigns for YardageKit.

5. Measurement, attribution, and analytics partners

YardageKit uses Adjust, a mobile measurement partner, to understand installs, sessions, reattribution, and campaign performance.

Depending on your permissions and device settings, measurement data may include:

• IDFA (only if you allow tracking)

• IDFV

• Adjust ADID

• App package name

• Attribution details such as campaign / tracker information when available

• Basic technical and install-related signals needed for measurement

Adjust may share measurement settings with advertising / attribution partners (for example Facebook / Meta) solely for install and campaign measurement related to YardageKit. Their handling of data is governed by their own privacy policies.

YardageKit does not sell your pour tickets, and does not use your pour history for third-party ad targeting across other companies’ apps.

6. What we do not collect for core pour features

For core pour sizing and curing follow-through, YardageKit is designed without:

• A YardageKit user account or login

• YardageKit cloud sync of your pours

• Sale of your pour history or personal information to data brokers

• Asking for your name, phone number, or payment card inside the App for core pour features

Measurement identifiers described in Sections 4–5 are used for install / campaign measurement, not to operate the pour calculator itself.

7. Internet use and the WebView

Core pour sizing, saved jobs, and curing follow-through work on device.

The App may use the internet when:

• You open this Privacy Policy or other linked pages inside the in-app WebView

• The App contacts measurement / attribution services such as Adjust

• The App needs network access for campaign measurement or to open an allowed linked page

When a page loads in the WebView:

• Your device requests the page from the host that publishes it

• The host (and your network provider) may process standard technical data typical of loading a webpage (such as IP address and device/browser information), under that host’s and your carrier’s practices

• YardageKit does not use the WebView to upload your pour history to our own backend as part of the pour-planning features

If a linked page is opened, limited measurement values already available on the device (such as IDFA when permitted, ADID, and package name) may be included so campaign performance can be measured. Those values are not your pour ticket contents.

8. Third parties

• Apple and your device platform provide system services such as local notifications, on-device storage, App Tracking Transparency, and App Store distribution.

• Adjust provides install measurement and marketing attribution services.

• Advertising / attribution partners connected through Adjust may receive measurement signals as described in Section 5.

• The web host that serves this Privacy Policy page processes page requests as described above.

Please review those parties’ policies for more detail. We do not sell your information to data brokers.

9. Children

YardageKit is a utilities-style tool for jobsite / DIY pour planning. It is not directed at children under 13. We do not knowingly collect personal information from children under 13.

10. Retention and deletion

Because pour data is stored on your device, you control it:

• Delete saved pours in the App where that action is available

• Clear App data, or offload/delete the App, in system Settings

• Uninstalling the App removes the App’s local data from that device (subject to how your operating system manages backups)

Measurement partners may retain technical measurement records according to their own retention practices. You can limit IDFA use by denying or turning off tracking permission in iOS Settings.

11. Estimates only

YardageKit provides estimates and field reminders only. It is not a substitute for a licensed engineer, supplier quote, bag label, project specification, or building code. Always verify quantities and curing practice with qualified professionals and your materials supplier before you pour or load a slab.

12. Changes

We may update this Privacy Policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the App after an update means you accept the revised Policy. The updated text will appear when you open the policy in the App’s WebView (or in a browser).
