About Casey

Casey is a personal scheduling assistant that integrates with your calendar to plan your week around what is already in it. Casey is made by the Happy Little Apps team, based in New South Wales, Australia. This policy explains what Casey collects, what it does with it, who else sees it, and how you remove it. Questions go to support@happylittle.app.

What Casey reads from your Google account

When you sign in, you grant Casey access to:

  • Your profile - your name, email address and profile picture, so Casey knows which account is yours and shows who is signed in.
  • Your calendar list - which calendars you have and your access to each, so you can choose the ones Casey plans around.
  • Your calendars - each calendar's timezone, so Casey plans in your time, and creating a new calendar when you ask Casey to make one.
  • Your events - Casey reads the events on the calendars you choose, and writes its own events to the calendar you pick for them.

From each Google Calendar event on the calendars you choose, Casey stores its title (an untitled event is stored as "Busy"), start and end times, location, organiser's email address, whether it shows you as free or busy, and your own response to it. Casey does not store an event's description or its list of attendees.

What you give Casey

  • Your tasks, the times of the week they can happen, and your preferences.
  • Pauses, when you tell Casey to leave a stretch of time alone.
  • The history of what you did and when, which Casey uses only to plan your own weeks.
  • When you turn on travel times, your home address and how you prefer to travel.

How Casey uses your data

Casey uses your data only to plan your week and keep your calendar up to date: to see when you are free, to place your tasks in suitable times, to move them when your week changes, and, with travel times on, to allow for the trip to an event.

Casey does not sell your data. Casey never uses data from Google, or anything derived from it, for advertising. Nobody at Casey reads your Google data unless you ask us to, for example to look into a problem you report, or where it is needed for security or to comply with the law.

Casey does not transfer, sell or use data from Google to create, train or improve a machine learning or artificial intelligence model, beyond your own personalised model for a feature Casey shows you. For example, Casey may learn that you often move Gym to 2pm, and uses that only to plan your own weeks.

The use of information received from Google Workspace scopes will adhere to the Google User Data Policy, including the Limited Use requirements.

Group events

A group event is one an organiser sets up for several people, who each say when they are free; Casey books a night when enough of them can make it. Everyone in a group event sees, for each other member:

  • their first name, with a last initial where two members share a name;
  • their profile picture, if they have one;
  • the times of the week they have added for the event;
  • which nights they can make. This comes from the times they added and from any night they have said yes or no to, and for a member with a Casey account, from whether their calendar is free that night.

No member ever sees what is on another member's calendar or what their events are called; Casey names the event that clashes with a night only to the person whose calendar it is on. When a night is booked, Casey adds the members to the organiser's Google Calendar event, and Google sends each of them its invitation, which shows the email address of everyone invited.

If you join an event without a Casey account

You can join a group event from its invitation link without signing in. Casey then stores:

  • the name you give;
  • your email address, only if you give one, which Casey uses only to add you to Google's invitation for a booked night;
  • your timezone and the times you add, and any night you say yes or no to.

The other members see these as described under Group events, apart from your email address, which appears only in Google's invitation. To remove them, choose Leave this event at the foot of the event's page. That deletes your place and your times, and your name and email address too unless you are in another Casey event. Or email support@happylittle.app.

Who else handles your data

Casey uses these service providers, each of which handles your data only to provide its service to Casey:

  • Google - sign-in, the Google Calendar API, Firebase Authentication for identity, Google Maps for travel times (which receives your home address and your events' locations), and hosting Casey's servers. Google's own handling of your data is covered by Google's Privacy Policy.
  • A database hosting provider, which stores Casey's database.
  • A network provider, which serves this website and passes the app's requests on to Casey's servers.

Casey's database and servers are in Australia.

Storage and security

Casey encrypts the tokens Google gives it for your account, with a key kept apart from the database, and uses them only to reach the Google services you allowed. Addresses Casey looks up for travel times are kept in a cache that is not linked to any user, for at most 30 days.

Deleting your data

  • Delete your account from the Danger zone at the foot of Settings. For 30 seconds you can undo it. After that, Casey removes its upcoming events from your calendar (past ones stay), cancels the group events you organise, takes you out of the ones you are in, revokes its access to your Google account, and deletes everything it holds about you. Copies in backups and logs are gone within 30 days.
  • Revoke Casey's access to your Google account without deleting your Casey account, at Google Account Permissions.
  • Leave a group event at the foot of its event page.
  • For anything else, email support@happylittle.app.

Changes to this policy

When this policy changes, we update this page and the date at the top. If a change affects how Casey uses your data, Casey shows a notice in the app before the change applies.
