sprntr is built without accounts, servers, or telemetry. The short version of this page is that your data stays on your device and in your own Apple account. The long version is below.
On-device data. Your workout history, program progress, settings, and preferences are stored locally on your device using SwiftData, Apple's local database framework. If you have iCloud enabled, SwiftData syncs this data across your own Apple devices using CloudKit. The sync runs inside your Apple account. sprntr never reads it and has no backup or copy of it.
Apple Health. If you grant permission, sprntr writes sprint workouts to Apple Health so they appear alongside your other activity, and reads workout history to avoid creating duplicates. This data stays in your Health database. sprntr does not transmit any Health data to third parties. You can revoke access at any time in iOS Settings → Privacy & Security → Health → sprntr.
Subscription status. Subscription purchases are handled by Apple's App Store. The App Store shares anonymized entitlement state with sprntr so the app knows whether to unlock Week 3+ content. sprntr does not see your payment method, your Apple ID, or your transaction history — only whether a premium entitlement is currently active.
Local notifications. If you enable workout reminders, sprntr schedules them directly on your device through iOS. No reminder data leaves your device.
Apple. sprntr uses HealthKit, iCloud, CloudKit, App Store, and StoreKit as a regular end user of Apple's developer platform. Your relationship with Apple is governed by Apple's own privacy policy.
RevenueCat. When subscription handling is active, RevenueCat validates App Store receipts on our behalf. RevenueCat sees only the anonymous App Store transaction identifier — not your name, email, or payment information. Their privacy policy is available at revenuecat.com/privacy.
This website. sprntr.app is served as static files. It loads web fonts from Google Fonts, which means your IP address is visible to Google when you load a page. If you sign up for the sprntr email list, your email address is stored by Buttondown (buttondown.com) so we can send you updates about the app. You can unsubscribe at any time from any email we send.
Because your workout data lives on your device and in your own iCloud, there is no sprntr account for us to delete. To remove your data:
sprntr is not directed at children under 13, and we do not knowingly collect data from children. If you believe a child has provided personal information through sprntr or the newsletter, contact us and we will remove it.
If this policy changes, we will post the update here with a new effective date. Material changes will be reflected in the app.
Questions about this policy: support@sprntr.app.
