Privacy Policy

Think is an iOS and watchOS app developed by Ivan Terziev (“we”, “us”). This policy explains what data the app handles and where it goes. The short version: Think collects nothing. Your journal lives on your device and, if you use iCloud, in your own iCloud account. We have no server, no account system, and no way to read what you write.

What we collect

Nothing. Think has no accounts, no analytics, no advertising, no tracking, and no third-party SDKs. The app never sends data to us. The only connection it makes is between your devices and Apple's iCloud, described below. Think may occasionally ask iOS to show Apple's standard rate-this-app prompt; that dialog belongs to Apple and we receive nothing from it.

Your journal

Journal entries, daily answers, evening retrospectives and focus-session notes (intention, outcome, energy) are stored in a database on your device.

If you are signed in to iCloud and iCloud is enabled for Think, the app also keeps a copy of that journal in the private database of your own iCloud account, so it can follow you to a new or second device. Changes, including deletions, sync in both directions. Apple encrypts this data in transit and at rest; it is tied to your Apple Account, not to us. We cannot access it. Think does not read or write anything else in your iCloud.

Sync is controlled from iOS Settings, not from inside the app: Settings → your name → iCloud → Think. If iCloud is off, unavailable or you are signed out, Think keeps working with the local copy only, and the Profile → Settings → iCloud sync panel tells you which state you are in.

Unsaved drafts are kept in a protected local file on the device and are not synced.

What else stays on your device

• Progress data (streak, focus sessions, path progress, achievements, saved lines) is stored in local app storage. On each device it is shared between the Think app and that device's widgets or complications through Apple's App Group mechanism. It is not part of iCloud sync, but it may be included in Apple device backups depending on your settings.
• Settings (appearance, reminder times, journal lock, Health logging, Live Activity preferences) are stored locally.

Apple Watch

The Watch app runs on its own. When your iPhone is reachable, the two exchange a small amount of data directly over Apple's device-to-device connection: the state of a running focus timer, and completed focus sessions, so that Watch sessions count toward the same streak. No server is involved. Journal content is never sent to the Watch.

Journal lock

You can lock the journal behind Face ID, Touch ID or your device passcode (Profile → Settings → Lock journal). Authentication is handled by iOS; Think only learns whether it succeeded. Exporting the journal always asks you to authenticate again.

Health

Optionally, Think can log completed focus sessions as mindful minutes in Apple Health (Profile → Settings → Log focus sessions to Health). This is off until you turn it on and grant access. Think only writes mindful minutes; it does not read any Health data. Minutes already written remain in Health if you later turn the setting off or delete Think.

Notifications

The daily line notification and the evening retrospective reminder are optional and scheduled locally on your device. Think also allows silent background notifications from iCloud so it can pick up journal changes made on another device; these carry no content and are not visible to you.

Live Activities and Siri

During a focus session Think can show a Live Activity on the Lock Screen and in the Dynamic Island. Whether your focus intention appears there is your choice (Profile → Settings → Show intention on Lock Screen). Think's Siri and Shortcuts actions run on your device and do not send anything to us.

Photos

If you save a quote card, streak card, achievement card or wallpaper, Think asks for write-only access to your photo library. The app only adds the image you created; it cannot read your photos.

Export and deletion

Profile → Settings → Export journal produces a plain-text copy of your journal that you can save or share wherever you like.

Profile → Settings → Delete all data removes your journal, drafts, focus notes, saved practices, progress and reminders from the device. Because deletions sync, the journal copy in your iCloud is removed as well.

If you delete the app instead, its local data goes with it. Any copy in your iCloud stays there until you delete it (Settings → your name → iCloud → Manage Storage) or turn iCloud off for Think and remove the data. Apple device backups may retain a copy until those backups are also deleted. Apple Watch data is deleted separately when you remove the app from the Watch.

Feedback

“Share an idea” and “Report a problem” open your own mail app with a draft that includes the app version and iOS version. You can see and edit everything before sending. Sending the email is your choice, and the contents are handled like any other email you send.

Children

Think is not directed at children under 13 and does not knowingly collect personal information from anyone, of any age.

Changes to this policy

If a future version of Think changes how your data is handled, this policy will be updated first and the “Last updated” date will change.
