Privacy Policy
Mark is built privacy-first. This explains exactly what the app handles, where it lives, and what we never do.
The short version: Mark is built privacy-first. Your journal, photos, moods, and history live on your device and in your own iCloud account. We don't run servers that store your content, we don't have accounts, we don't use analytics or ad trackers, and we never sell your data. We genuinely can't see what you write.
This Privacy Policy explains how the Mark app ("Mark," "the app," "we," "us") handles your information. It applies to the Mark iOS application.
Mark is published by northOS. For any privacy question, contact us at support@northos.xyz.
Mark is designed so that your personal content stays with you. The app has no login and no account. It uses Apple's iCloud to sync your data privately across your own devices. We do not operate a database of your entries.
Everything you create in Mark is stored locally on your device and, if you have iCloud enabled, synced through your private iCloud (Apple CloudKit) database — which only you can access. This includes:
We, the developer, do not receive, store, or have access to any of this content.
When a moment records weather, Mark requests it from Apple WeatherKit using the moment's approximate location and time. This is handled by Apple under Apple's terms and privacy practices. Weather data is stored with your entry in your own iCloud, not with us.
Location is optional and user-initiated. If you choose to attach a place to a moment, Mark uses your device location once to drop a map pin and look up a place name (via Apple's services). Mark does not track your location in the background or build a location history. You can decline or revoke location access at any time in iOS Settings → Privacy & Security → Location Services.
Mark lets you create a branded recap card (a day, week, or year) and share it yourself via the iOS share sheet (Messages, email, social, etc.). These cards are generated on your device. When you share one, you are sending it through the app or service you choose — Mark does not transmit it to us. Shared cards carry Mark branding and a link to the app.
If you purchase a Mark subscription, the transaction is processed entirely by Apple through the App Store. Apple handles your payment information; we never see or store your card details. We may receive anonymized purchase status from Apple solely to unlock features.
Reminders are delivered as local notifications scheduled on your device. They are not sent through our servers.
Because your data lives on your device and in your iCloud, you control it:
There is no account on our side to delete, because we don't hold your data.
Mark is a general-audience app and is not directed at children under 13 (or the equivalent minimum age in your region). We do not knowingly collect data from children.
Depending on where you live (e.g., GDPR in Europe, CCPA in California, PIPEDA / Québec Law 25 in Canada), you may have rights to access, correct, or delete personal data. Because your Mark data is stored in your own device and iCloud and not on our servers, you can already exercise these directly (see §10). For any question, contact support@northos.xyz.
The only third party involved in the app's core function is Apple (iCloud/CloudKit, WeatherKit, Maps/geocoding, App Store purchases), governed by Apple's own privacy policy. We do not integrate advertising or analytics providers.
If we update this policy, we'll change the "Last updated" date above and, for material changes, surface a notice in the app or on our site.
