Daybook is a personal planner made and run by one person. It keeps what it needs to print your day and nothing it can do without. There is no advertising in it, no analytics library, and nothing about you is sold, rented or handed to anyone for their own use.
What Daybook keeps
- Your account. Your email address, a hash of your password or the public half of any passkey you add, a display name if you give one, your time zone, your choice of the day or night edition, and which plan the account is on, with the date it ends if it has one and, for a paid plan, Paddle's customer and subscription ids.
- What you enter. Your tasks, sections, notes, habits, countdowns, time entries, assets and any photos you attach to them, and any feedback you file.
- How you use it. When you last signed in, and, for each device you turn reminders on for, the token that lets reminders reach it.
What it is for
Running Daybook for you: showing you your page, sending you the emails and reminders you ask for, and keeping the phone and the browser on the same copy. Nothing is used to profile you or to advertise to you.
Who else handles it
A few services do jobs the site cannot do on its own. Each receives only what that job needs.
- Railway runs the site and its database.
- Brevo delivers the emails Daybook sends: the confirmation of your address, password reset codes, and sharing invitations.
- Apple carries reminders to the iPhone app through its push service; a browser's own push service carries them to the web.
- Paddle takes payment for Pro, as the merchant of record. Your card and billing address go to Paddle and never to Daybook; Daybook sends Paddle your email address and account id so the purchase can be matched to you, and receives back which plan you bought and its dates.
A section you share is visible to the people you share it with, and their changes are visible to you. Stop sharing it and it is yours alone again.
How long it is kept
Until you delete it. Confirmation and reset codes expire after fifteen minutes and are spent when used. Deleting your account removes the account and everything entered under it.
Your choices
- Take a copy. Sign in on the web and open Account, then Personal data, to download everything Daybook holds for you.
- Delete your account. In the iPhone app, open Settings and choose Delete account. On the web, open Account, then Personal data, then Delete.
- Turn reminders off. On the web, under Account, then Notifications. On the iPhone, in the phone's own Settings for Daybook.
- Remove a passkey. Under Account, then Passkeys.
Cookies
One cookie keeps you signed in. There are no third-party cookies. The site stores its own files in your browser so the page opens when you are offline.
Children
Daybook is not directed at children under thirteen and does not knowingly keep an account for one.
Changes
When this notice changes, the revised date at the top moves. The current copy is always at this address.
