Spark to Flame privacy policy

Last updated 10 November 2026

The short version: Spark to Flame collects nothing. It has no accounts, no analytics, no advertising, no crash reporting and no third-party code. It doesn't send anything to us or to anyone else. The app's only connection to the internet is Apple's App Store, used when you buy or restore the full version.

Who we are

Spark to Flame is made by Joshua Smith, publishing as Rational Pi. Questions about this policy go to sparktoflame@rationalpi.com.

Location

If you allow it, the app uses your approximate location for two things: to show the materials that grow in your part of the US, and to work out the time of sunset for night mode. Both are done entirely on your iPhone or iPad, with map outlines and a sunset formula built into the app. Your location is never sent anywhere, not even to look up a place name.

You can say no, or turn it off later in Settings, and pick a region yourself instead.

What stays on your device

Your settings: the region, "Show everything", and night mode.
Your last approximate location, so the region and sunset are right the next time you open the app.
The how-to items you've checked off. They clear at 2 AM each day.
Your screen brightness, if night mode dims the screen, so it can be put back when night mode ends.
In the full version: your patrol names, the troop inventory and the last contest result.

None of this is sent anywhere. The app doesn't sync it; like all app data, it's part of your device's own backup if you have one. Deleting the app removes all of it.

Purchases

Spark to Flame is free. A one-time purchase unlocks the full version. Buying and Restore Purchases use Apple's own App Store screens. Apple handles the payment under its own privacy policy. We never see your name, email address, Apple Account or payment details; the app only asks Apple whether this Apple Account owns the full version.

Links

The app's Settings screen links to rationalpi.com, which opens in Safari, and can open the device's Settings app to change the location permission. There are no other links and no web pages inside the app.

What Apple may share with us

Apple gives app makers total downloads and sales. If you've chosen in your device's settings to share analytics with app developers, Apple may also give us crash reports and usage statistics that don't identify you. That information is collected by Apple under Apple's privacy policy, not by Spark to Flame.

Children

Spark to Flame is for scouts, their leaders and other campers, including young people. It collects no personal information from anyone, including children under 13, so there's nothing for a parent to review or ask us to delete.

If you email us

If you write to sparktoflame@rationalpi.com, we use your email address and message only to reply. We don't add you to any list or share your message.

Changes to this policy
