Day One is a mature cross-platform journal with sync and end-to-end encrypted storage. Harbour is a Mac-only, local-first app focused on private on-device AI. Day One's AI documentation says current AI features use server processing and may temporarily decrypt selected content for AI processing. Day One's AI feature guide lists several AI features for iPhone, iPad, Android, and Web; Mac availability may vary by feature.

Questions before you start.
Simple answers to key details.
Will this work on my Mac?
Harbour works on Apple Silicon Macs with at least 16 GB of memory. It does not work on iPhone, iPad, Android, Windows, or Intel Macs.
Do I need a credit card for the trial?
No. The 14-day trial does not collect payment details. If Harbour fits, you can buy a lifetime license later.
When does the trial clock start?
Your 14-day trial starts after your first app activation. You need internet for the first setup.
Is there a subscription?
Nope! After the trial, Harbour is a one-time purchase with no subscription and no cloud account required.
How private is it?
Harbour is built around privacy. Your journal is stored on your Mac. Private AI runs on your device. You can add a PIN or password before the app opens.
How can an AI journal be private?
Most AI apps send your words to another company's computers. Harbour's AI can run on your Mac instead. Your journal can stay on your device while Harbour helps you reflect.
What happens after I start the trial?
Confirm your email, then you get a download link and activation key. Install Harbour on your Mac. Enter the key during setup. That starts the 14-day trial.
Can I get a refund?
Yes. Harbour has a 14-day, no-questions-asked money-back guarantee from the date and time of purchase.
Why not use a cloud AI journal?
Cloud tools can be useful, but a journal is personal. With a cloud journal, you must trust another account, another security model, and another company. Harbour keeps your entries on your Mac. It also has no ongoing subscription.
License disclosure
The free trial includes a personal 14-day trial license to use Harbour Journal for one individual. Trial time starts on first successful activation in the app, not when the key is reserved. Purchase includes a personal lifetime license to use Harbour Journal for one individual, subject to the license and refund terms. There is no subscription and no scheduled expiration for paid lifetime licenses. Harbour may periodically check license validity. Licenses may be revoked or disabled after a refund, chargeback, fraud, abuse, license sharing beyond permitted use, or serious terms violation.
