Privacy Policy

Calub is a private calendar for families. This policy explains what we collect, why, and what we never do with it. “Calub,” “we” and “us” mean the people who run the Calub app and the website at calub.app.

The short version: your family's calendar is visible only to the people in your family. We don't sell your information, we don't show ads, and we don't use tracking or analytics tools.

What we collect

• Your email address, so you can sign in. We email you a 6-digit code instead of using passwords.
• Your family's details that you enter: the family name, each person's first name and color, and who is a grown-up or a kid. Kids can be added as a name and color only, with no email or login.
• Your calendar: event titles, dates and times, who each event is for, repeat settings, reminders, and any location or notes you add.
• Invites: the email address of anyone you invite to your family, so we can send them the invite and let them in.
• Linked calendars (optional): if you link an outside calendar (like Google, Zoho or Outlook), we store its private address and a copy of its upcoming events so they can appear in your lane. The address is visible only to you.
• Reminder settings (optional): if you turn on reminders, your phone or browser gives us a notification address so we can send you alerts. It doesn't include your phone number or location.

We don't collect your location, contacts, photos, or anything from your device beyond what's listed here. A few display preferences (light or dark mode, zoom level, who's hidden on your screen) are saved only on your own device.

How we use it

• To run Calub: show your family's calendar to your family, keep it in sync, and send the reminders you ask for.
• To send sign-in codes and family invites by email.
• To keep the service secure and working, and to answer you when you contact us.

We don't sell or rent your information, use it for advertising, or share it with data brokers. We don't build profiles of you or your kids.

Who can see your calendar

Only the members of your family who have a login: the grown-ups you invite and any kids you give a login. Every request is checked against your family membership, so other families can't see your information. We don't look at your calendar except when needed to fix a problem you report or to keep the service secure.

Services we use

We use a small number of companies to run Calub. They handle your information only to provide their service to us:

• Supabase: our database and sign-in system (servers in the eastern United States).
• Vercel: hosts the app and website.
• Resend: sends our emails (sign-in codes and invites).
• Apple, Google and other browser makers: deliver reminder notifications to your device if you turn them on.

If you link an outside calendar, Calub reads it from that provider (for example Google or Zoho) every 15 minutes.

Children

Calub is used by parents to organize their family. Parents may add their kids as a first name and a color. A parent can also choose to give a child their own login by entering the child's email address; we recommend doing that only for kids 13 and older. A grown-up in the family can remove a kid's login at any time, and a kid's profile can be deleted by the Family Admin. If you believe a child under 13 has given us information without a parent's permission, contact us at hello@calub.app and we'll delete it.

How long we keep it, and deleting it

We keep your information for as long as your family uses Calub. Events and people you delete are removed from the calendar right away. You can delete your account yourself in the app: Settings → Delete my account. The Family Admin can delete the whole family there too. You can also email hello@calub.app from the address you sign in with, and we'll delete it within 30 days. Any copies in our providers' backups expire on their normal schedule.

Security

Everything is sent over encrypted connections (HTTPS). Sign-in uses one-time codes, so there are no passwords to steal. Access to each family's data is enforced by the database itself. No system is perfectly secure, but we work to protect your information and will tell you if a problem affects it.

Your choices

• You can edit or delete events and people in the app at any time.
• You can turn reminders off in Settings, and unlink an outside calendar in Settings.
• You can ask us for a copy of your information, or to correct or delete it, at hello@calub.app.

Changes

If we change this policy, we'll update the date at the top. If a change is significant, we'll let you know in the app or by email before it takes effect.
