Yes. Tendi stores journal content on your device by default. If you enable iCloud sync, it syncs through your personal Apple iCloud account, not a Tendi journal server. Optional analytics are off by default and never include journal content.

No. Tendi is built to work without an account.

Tendi is free, with no subscriptions and no ads. If you would like to support the work, you can buy us a coffee.

Tendi supports iPhone on iOS 17.2 or later. Its Apple Watch companion app supports watchOS 10 or later.

A Tendi backup is the only export format capable of a complete restore. It includes entries, activities, settings, and Important Days, and can include photos and voice notes when you select those options. JSON includes entries and Important Days, CSV includes entries, and PDF creates a readable report rather than a backup. Use a full Tendi backup when moving your journal to a new device.

You can delete individual entries or use Delete All Data in Tendi settings. Delete All Data also cancels Tendi reminders and Important Day notifications. If you use iCloud sync, make deletion changes inside Tendi so they can sync through your personal iCloud. Deleting the app only removes that device's local copy; it does not issue iCloud deletions, so synced data may remain in iCloud or on other devices and may return after reinstall. You can also manage Tendi data through Apple's iCloud settings.

Core journaling, history, maps, and local insights work offline. iCloud sync and external resources such as Find a Helpline need an internet connection.
