What TeamTime is
A small tool for finding a regular meeting time for a group, like a kids' robotics team. Each family enters when their kid can or can't make it, and everyone in the group sees the overlap.
What we store
- From Google when a parent signs in: email address, name and Google's account ID. We never see your password, contacts or calendar.
- For each group: its name, its 4-digit code, its time zone, the organizer's settings, and a log of changes (who joined, who submitted, what times were added or removed).
- For each family in a group: the kid's nickname, whether you entered times that work or times that don't, and the times themselves, with any notes you typed.
- For events: title, date, times, location, notes, creator nickname, family RSVPs, optional weekly recurrence rules, series-wide response preferences and individual exceptions, and a history of edits and responses. RSVPs are plans, not attendance records.
- To keep you signed in: one cookie with a random key for up to 30 days. We keep only a scrambled (hashed) copy. No advertising or tracking cookies.
Who can see what
- Only signed-in members of a group see that group: the kid nicknames, everyone's times and notes, events and family responses, and the change log.
- Members never see each other's email addresses.
- People join through the invite link, whose long random token can't be guessed. Someone with only the 4-digit code can ask to join; the organizer sees the request and approves or declines it. Wrong codes and links are limited to 10 tries per 15 minutes. The organizer can replace the invite link and remove members.
- Tip: a nickname is enough, and notes like “swim” are plenty. Please don't put addresses, school names or phone numbers in notes.
How long we keep it
- Past one-off availability entries are deleted. Past and cancelled events are retained for reference until their creator or organizer deletes them, or the group is deleted. Deleting an event removes its details, responses and event history; the group change log keeps a brief deletion record and prior activity.
- Leaving a group removes your kid's times from it (the log keeps a line saying you left). Event records and historical nicknames remain for the team unless the event is deleted. When the last member leaves, the group is deleted.
- “Delete my account” at the bottom of the app removes your sign-in and takes you out of every group.
Services we use
- Google handles sign-in.
- Railway hosts the app and stores its data.
- Cloudflare Web Analytics counts page views and visits so we know how the site is used. It sets no cookies and doesn't track you across sites; it sees the page address, your browser type and rough location, not your groups or times.
- “Copy for WhatsApp” only copies text to your clipboard; you choose where to paste it.
- AI assistants you connect (such as Claude or ChatGPT, under “Group → AI assistants”) can see your groups, including other families' times and notes, enter your kid's times, read and propose events, and respond for your family. They can also edit, cancel or delete events you manage, and confirm events if you are the organizer. What they read, and what you tell them, is handled by the company behind them under its own privacy policy. They're for adults. Disconnecting, or deleting your account, cuts off access right away; we keep only scrambled (hashed) copies of their access keys.
We don't sell or share your information, and there are no ads.
