Privacy policy
We don't have your prayers.
Koum holds some of the most personal writing a person does. The design answer was to never collect it. There is no Koum account or server holding your content; it stays in the private iCloud connected to your Apple Account.
Last updated 5 August 2026
This policy explains what Koum (“the app”, “we”) does with information when you use it on iPhone. It applies to the Koum iOS app and to this website.
What we never collect
- No account, email address, name or password. Koum has no sign-in.
- Your journal entries, prayers, streaks, alarm settings and reading history are never sent to us and we have no way to read them.
- No advertising identifiers, no ad networks, no data brokers.
- We do not sell or share personal information. There is nothing to sell.
Where your content lives
Everything you write or record in Koum is stored on your iPhone and synced through your own private CloudKit database — an area of your personal iCloud that Apple encrypts and that the developer of an app cannot access. It is connected to your Apple Account, so it returns when you reinstall Koum or sign in on another Apple device with that same account.
Deleting the app removes only its local copy; it does not delete the private iCloud copy. Koum → Settings → Delete all data removes both the local copy and the private iCloud copy. Neither can be recovered by us, because we never had them.
Camera
Scanning uses the camera to read the page in front of you. Frames are processed on the device by Apple's Vision framework and discarded immediately. Images are never written to disk, never added to your photo library, and never uploaded.
When an on-device read is ambiguous, Koum may send the recognised text only — never the image — to a third-party language model to ask which passage it comes from. That text is a few lines of Scripture; it contains nothing about you, it is not linked to any identifier, and it is not retained by us. Most mornings never reach this step, because the on-device match succeeds first. You can avoid it entirely by using Say it or Type it.
Microphone and speech
Saying the verse aloud uses Apple's on-device speech recognition. Audio is transcribed on the iPhone and is not uploaded, not stored, and not sent to us.
Notifications
Koum uses local notifications and Apple's AlarmKit to ring alarms and to send the reminders described in the app. These are scheduled on your device. No push server is involved and no notification content leaves your iPhone.
Subscriptions
Subscriptions are purchased through Apple's In-App Purchase and managed with RevenueCat, which records purchase events so the app knows whether your subscription is active. RevenueCat receives an anonymous app-generated identifier and Apple's transaction data. It does not receive your name, your email address, or anything you write in the app. Apple never gives us your payment details.
Diagnostics and analytics
Koum uses Sentry to receive crash reports and error diagnostics so we can find and fix problems. Those reports may include technical details such as the app version, device type, operating system, time of an error, and the error trace. They are not intended to include the Scripture, prayer, journal, or audio content you create in the app.
Koum uses Mixpanel to understand onboarding and how people use product features. Mixpanel receives pseudonymous usage events, such as which onboarding step or feature was used, along with technical app context. It does not receive your name, email address, prayers, journal entries, recordings, or reading history.
This website
koumapp.com uses Vercel Web Analytics and Ahrefs Analytics to understand website visits. For public product pages, we also measure recognized search and AI referral sources, the landing page, and guide call-to-action clicks. This referral grouping uses session storage in your browser; custom referral events do not include full referrer URLs, search terms, prayers, or journal content. Hosting providers may process standard request logs for security and reliability.
Children
Koum is not directed at children under 13 and we do not knowingly collect information from them. Since the app collects no personal information from anyone, there is nothing held about a child either.
Your rights
Under the GDPR, the UK GDPR, the CCPA and similar laws you have rights of access, correction, deletion and portability over personal data a company holds about you. In Koum's case those rights are satisfied directly on your device: your data is in your hands, and Delete all data exercises the right to erasure completely. If you believe we hold something about you, email us and we will tell you exactly what we can see, which is very little.
Changes
If this policy changes we will update the date at the top and, for any change that affects what is collected, say so in the app before it takes effect.
