Privacy Policy

Last updated: November 5, 2026

Ontime ("we", "our", or "the app") is a timezone comparison and meeting scheduling tool available at ontime.bymena.design. This privacy policy explains how we handle your information when you use our service.

1. Information We Collect

If you sign in with Google (optional):

Email address — shown in the app so you can see which Google Calendar events will be added to

If you turn on notifications (optional, off by default):

Your browser's push address — so we can deliver notifications to this device
Your timezone — so the daily digest arrives at the hour you chose
Cities you ask us to watch — the city name, its timezone and your working hours, for "good time to call" alerts
Meeting reminders — the meeting title and start time, so we can remind you 10 minutes before

Information collected automatically:

Timezone — detected from your browser to provide timezone conversion
Basic analytics — anonymous page view data via Vercel Analytics (no personal identifiers)

2. Google API Services

Ontime uses Google OAuth 2.0 for authentication and requests access to the following scopes:

Google Calendar (calendar.events.owned) — to create an event in your calendar when you press "Add to Google Calendar". Ontime only creates the event you asked for; it never reads, changes or deletes your other events
Email address (userinfo.email) — to show which Google account (and so which calendar) you're signed in with

Ontime's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

3. How We Use Your Information

Show your email address in the app, so you know which calendar events go to
Create Google Calendar events when you use the "Add to calendar" feature while signed in
Send the notifications you turned on
Store your authentication session so you don't need to sign in repeatedly

We do not use your data for advertising, profiling, or any purpose beyond the app's core functionality.

4. Data Storage

Most of Ontime runs in your browser, and most of what it remembers stays there, in localStorage:

Authentication token — your Google OAuth access token, stored temporarily until it expires
Your email address — cached locally for display
App preferences — your cities, recent cities, working hours and sound setting

The only data stored on a server is what notifications need (listed in section 1), and only if you turn notifications on. It's kept in a database run for us by Supabase and is deleted when you turn notifications off. Your Google account details and calendar are never stored on a server.

5. Data Sharing

We do not sell, trade, rent, or share your personal information with any third parties. Your data goes to other services only when you ask for it: Google's Calendar API (when you add an event while signed in), Google Calendar in a new tab (when you use "Open Google Calendar without signing in", which passes the event details in the link), and Supabase plus your browser's push service (when notifications are on).

6. Data Retention and Deletion

Since all data is stored in your browser's localStorage, you have full control over it:

Sign out — clears your authentication data and revokes the Google access token
Turn off notifications — deletes your push address, watched cities and reminders from our database
Clear browser data — removes all locally stored information

We keep nothing on a server unless you've turned notifications on.

7. Security

Ontime uses Google's OAuth 2.0 protocol for secure authentication. Access tokens are short-lived and are revoked upon sign-out. All communication with Google APIs occurs over encrypted HTTPS connections.

8. Children's Privacy

Ontime is not directed at children under 13. We do not knowingly collect personal information from children.

9. Changes to This Policy

We may update this privacy policy from time to time. Changes will be reflected by updating the "Last updated" date at the top of this page.
