Daydeck Privacy Policy

Updated:

Daydeck is a browser extension for Google Chrome and Microsoft Edge, made by HYPER PORT LLC (“we”). This policy explains what the extension does with your information.

In short

  • We run no server for Daydeck. Your calendar never comes to us, and we cannot see it.
  • There is no account with us, no advertising, no analytics and no tracking. We do not sell or share your data.
  • Your data stays in your browser and, if you turn on sync, in your own Google Drive or OneDrive.

What is kept on your computer

The calendars and events you create, your settings, your reminders and a temporary copy of the events from calendars you connect are stored in your browser’s storage on this computer.

Sign-in tokens for Google or Microsoft are also kept only on this computer. They are never sent to us and never written to the sync file. Uninstalling the extension deletes all of this.

Connected calendars (optional)

If you connect Google Calendar or Microsoft Outlook, the extension signs in with Google or Microsoft and then talks directly to their services (www.googleapis.com and graph.microsoft.com) to show, create, change and delete events when you ask it to.

If you add an ICS feed, the extension downloads it directly from the address you enter, after asking your browser’s permission for that site. Nothing passes through us.

Sync between your computers (optional)

When you turn on sync (one approval the first time), the extension saves one file, kairo-sync.json, in the storage of the account your browser is signed in to: in Chrome, that Google account’s Google Drive, in a hidden app-data folder that only Daydeck can open; in Edge, that Microsoft account’s OneDrive, in its Apps folder.

The file holds the calendars and events you created in Daydeck (titles, times, places, notes and repeats), your calendar list (names, colours, ICS addresses, and which Google or Outlook calendars you show, with the address of their account) and your calendar settings (language, time zone, first day of the week and holidays). It does not hold sign-in tokens or the events stored in your Google or Outlook calendars.

To choose and check where to sync, the extension reads the email address of the account your browser is signed in to. It sends that address only to Google or Microsoft, as a sign-in hint. Before sync is on, opening the panel may quietly ask Google or Microsoft whether this account has already allowed Daydeck, so that a second computer can sync without a click.

Reminders

If you turn on reminders, they are prepared on your computer and shown by your browser.

How your data is protected

  • No server in between: the extension talks directly to Google and Microsoft over encrypted HTTPS (TLS) connections. Your calendar data and sign-in tokens never pass through us or reach us.
  • Your password stays with Google or Microsoft: you sign in on their own sign-in page, in a window your browser opens. Daydeck never sees or stores your password.
  • Only the access it needs: your calendar events and your list of calendars (not your mail, contacts or files), and for sync only Daydeck's own app folder in Google Drive or OneDrive; it cannot see your other files.
  • Short-lived sign-in tokens: each token expires after about an hour, and no long-term (refresh) token is kept. Tokens are stored apart from your data and are never included in backups or in the sync file. You can revoke them at any time (see below).
  • On your computer, your data is kept in the extension's own browser storage, which websites and other extensions cannot read, under your computer's user account. Uninstalling the extension deletes it.
  • The sync file is stored in your own Google Drive or OneDrive, under Google's or Microsoft's security, and is only ever sent over HTTPS.
  • We do not collect, log or look at your data. If you find a security problem, please write to support@hyperport.jp.

Google user data

Daydeck’s use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy (https://developers.google.com/terms/api-services-user-data-policy), including the Limited Use requirements.

Google user data is used only to provide the calendar features you see in the extension. It is not transferred to anyone else (other than into your own sync file, as described above), not used for advertising, and not read by people.

Deleting your data and removing access

  • On this computer: Settings › Advanced › Delete this device's data, or uninstall the extension.
  • The sync file: in Google Drive, Settings › Manage apps › Daydeck › Delete hidden app data; in OneDrive, delete the app’s folder inside the Apps folder.
  • Access to your account: remove Daydeck at https://myaccount.google.com/permissions (Google) or https://account.live.com/consent/Manage (Microsoft).

Children

Daydeck is not directed at children under 13.
