Privacy Policy

What we collect

• From Google sign-in: your name, email address and Google account ID. That's all sign-in asks Google for.
• What you tell us: the city you pick (we store its time zone), the times that suit you, your answers to the short questionnaire, and whether you want AI to write your circle's questions.
• Your circles: the circles you start or join, their names, the nudge day, the week's format, a meeting place for in-person weeks, and a group chat link if someone adds one.
• Emails we send you: we keep a copy of each one so we can check it went out.
• Cookies: one sign-in cookie that lasts up to 30 days, and a short one (10 minutes) that keeps Google sign-in secure. No other cookies.

We don't store photos, voice memos or videos. Those stay in your own group chat, outside Drift Circle.

Google Calendar, only if you choose

Connecting your calendar is optional. If you do, here is exactly what we can and can't do.

• Free/busy only. We ask Google when you are busy in the week ahead so we can suggest a time that works for the circle. Google tells us busy times and nothing else: no event names, places, notes or guests. We don't save your busy times, only the time we pick for the circle.
• Booking calls, for hosts. If you host a circle and allow it, we add the week's call to your own Google Calendar, with a Google Meet link or the meeting place, and invite the friends in your circle. Google sends those invites from your account, and guests can see each other's email addresses on the invite. We can only create and change events we made on your calendar. We can't see or edit anything else on it.
• To keep this working week to week, Google gives us a key to your calendar access. We store it encrypted (AES-256).
• You can disconnect any time in Settings, which also cancels the key with Google. You can also remove access from your Google Account.

Drift Circle's use of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Your answers and the AI

Each week, everyone in the circle gets one question to ask one friend. The question comes from that friend's answers.

• AI on (the default): Claude, an AI made by Anthropic, writes the questions. We send it your first name and your answers. Nothing from your calendar goes to it.
• AI off: your answers never go to Claude. Friends get a simple question instead, which may quote your own words. Turn this on or off in Settings.
• "Anything you'd rather not be asked about?" This answer is never shown to anyone, friends included. If AI is on, Claude gets it only as a list of things not to mention. It is never used in the simple questions.

What your friends see

• In a circle, friends see your name, your city and whether your nudges are paused.
• Your other answers reach friends only through the weekly question, which is based on what you wrote and may quote it. We never show your full answers to anyone.
• Weekly emails mention the first names of the friends in your circle.

Companies that help us run Drift Circle

We use a few service providers. Each one gets only what it needs to do its job.

• Google: sign-in and, if you connect it, your calendar.
• Anthropic: writes the weekly questions when AI is on (see above).
• Resend: delivers our emails, so it handles your email address and what each email says.
• Neon: hosts our database, where your account information is stored.
• Vercel: hosts the app and runs the job that sends the weekly emails.

The Mission MarkeTech logo at the bottom of each page loads from our own website, missionmarke.tech. We don't sell, rent or trade your information, and we don't use it for ads.

How we protect it

Google calendar keys are encrypted before we store them, sign-in cookies can't be read by other sites or scripts, and only members of a circle can see that circle. No system is perfectly safe, so we keep only what the app needs.

Your choices, and deleting everything

• Pause: every nudge email has a link to pause it. You can also pause or resume on the circle's page.
• Leave a circle: any time, from the circle's page.
• Edit your answers or turn AI off: any time, in Settings.
• Delete your account: in Settings. This removes your name, email, answers, your place in every circle and the copies of emails we sent you, and disconnects Google. A circle you started passes to the friend who has been in it longest. A circle with only you in it is removed.

A few things live outside our database, so deleting your account can't reach them: emails already in your friends' inboxes (which may mention your first name or a question based on your answers), calendar invites a host already sent, and records our service providers keep for a limited time under their own policies.

Age

Drift Circle is for adults. It isn't meant for anyone under 18, and we don't knowingly collect information from children.

Changes

If this policy changes, we'll update this page and the date at the top.
