Privacy

What’s stored, and where

To remember this week’s challenge and your progress, the app saves a small amount of data in your browser’s local storage, on your device only:

• which challenge you got this week, and whether you’ve done it
• which challenges you’ve completed, and when
• which pack you’re playing, challenges you’ve saved for later, and any packs you’ve unlocked

This data is never sent to us or anyone else. We can’t see it. It contains no name, email, location or other personal details.

Anonymous usage statistics

To understand how Challenge Spin is used and how to improve it, we collect anonymous totals using two privacy-focused tools. Neither uses cookies or asks for your name or email.

Visits (Cloudflare Web Analytics): how many times pages were visited, which website or app a visit came from (for example, a shared link), country, device and browser type, and how quickly pages loaded.

How the app is used (Umami): simple counts of actions such as spinning the wheel, saving a challenge for later, tapping “I did it”, opening your progress, and sharing. Each count can include a few general details that help us improve the challenges, for example:

• the category and intensity of the challenge (e.g. “Kindness”, “Bold”), but not the challenge itself
• rough ranges such as “3–5 challenges completed” or “2-week streak”, never exact personal records
• whether the app was opened from your home screen

These statistics contain no user ID, name, email or other personal details, and they aren’t linked across websites or used for advertising. We only ever see totals, so we can’t see what any one person did. You can read more in Cloudflare’s privacy policy and Umami’s privacy policy. If your browser or a content blocker blocks analytics, the app works exactly the same.

What we don’t do

• No accounts or sign-up
• No advertising, and no advertising or cross-site tracking cookies
• No storing your name, email address, contacts or precise location
• No selling or sharing of personal data, because we don’t have any

Buying packs

Paid packs are sold through Stripe (Stripe Managed Payments), which acts as the seller (“merchant of record”). Stripe handles your payment, receipt and tax, and receives the details you enter at checkout (such as your email and payment information) under Stripe’s privacy policy. We never see your card details.

When a purchase completes, Stripe tells us which pack was bought and the email used. We keep only a scrambled, one-way code made from that email (it can’t be turned back into your address) plus which packs it bought, so you can restore them later. Your device keeps an unlock code for the packs you own.

Prices in your currency: to show prices in your local currency, the app asks our server which country your connection comes from (our host, Cloudflare, works this out from your IP address). Only the country code is kept, on your device. We don’t store it, your IP address or your location.

Restoring: if you ask to restore purchases, we send a one-time link to the email you enter, using our email provider Resend. We don’t keep the address after sending.

Sharing

When you tap Share, the image and text are created on your device and handed to your phone’s own share menu (or copied or saved, if you choose). Where they go next is up to you and the app you share to. Nothing passes through us.

Hosting

Challenge Spin is hosted by Cloudflare. Like every website host, Cloudflare may briefly keep standard technical logs (such as IP address and browser type) to deliver the site and protect it from abuse. We don’t use these logs to identify or profile you.

Your control

You can erase everything at any time: open Your progress → Reset progress in the app, or clear this site’s data in your browser settings. Deleting the app from your home screen and clearing site data removes it completely. To have your purchase record deleted, email us from the address you paid with.

Changes and contact

If this ever changes (for example if we add accounts), we’ll update this page before it happens.
