Privacy Policy

What BUZZIN collects, who can see it, and how to get it back or get rid of it.

The short version

•BUZZIN collects what it needs to show your posts to your friends and count your streak. Not much more.
•We do not sell your personal information. We may eventually share anonymous group trends — the full story is below and in the Terms.
•Your exact location and your phone number are stored in a way that no other user can read, by design.
•Questions, or want your data out? Email buzzincaffeine@gmail.com.

•Your email address and password, or — if you use Continue with Google or Continue with Apple — the account identifier and email that provider hands us. We never see your Google or Apple password.
•A username, and optionally a display name, short bio, and avatar photo.
•Your birth year, so we can check you're 13 or older. We keep the year and the date you told us, not your full date of birth.
•Your time zone, so your streak rolls over at your midnight instead of someone else's.
•Optionally a phone number, only so friends who already have it can find you.

•Your posts: which drink, the photo or photos, the day and time, and whether it was a rest-day check-in.
•Who you're friends with, the comments you write, and the reactions you leave.
•Any communities you create or join, and which posts you aimed at them.
•Your streak count and which streak badges you've already been shown, so we don't celebrate the same one twice.
•If you tag a post with a location: the precise coordinates, plus a coarse label like a city or a café name.

•Posts are friends-only by default. Each time you post you choose: friends, public on Discover, or one community you've joined. A community post is never also public.
•Public posts and public profile fields can be seen by anyone, including people who aren't logged in and link-preview bots.
•Comments are limited to the post's author and their friends. Reactions work on any post you can already see.
•Your phone number is never shown to another user. The database will not return it to anyone but you — that's enforced at the column level, not just hidden in the app.
•The precise coordinates on a post are never returned to any user, including you, after the post is made. Only the coarse label is ever displayed. That's also enforced at the column level.

•Supabase hosts our database, sign-in, and photo storage. Vercel hosts and serves the app. Both process data on our behalf so BUZZIN can run.
•Google and Apple, only if you choose their sign-in button, and only to confirm it's you.
•OpenStreetMap, but not directly from your device: the café and shop listings come from our own copy, which our server refreshes one neighbourhood at a time in the background. Those refreshes ask about an area, never about a person, and are not triggered by or tied to any individual search.
•BigDataCloud, to turn those coordinates into a city label: again one lookup, nothing that identifies you.
•That's the whole list. We don't use advertising networks or third-party analytics trackers.

•Post photos are deleted on a schedule. Every Monday we remove the images on posts from previous weeks and clear them from storage. Posts you've pinned keep their photos.
•The post record itself stays after its photo is gone — the drink, the day, the coarse label — so your streak and your all-time count stay accurate.
•Delete a post yourself and the whole thing goes, photo included, right away.
•Your profile stays until you ask us to delete your account.

•We do not sell your personal information today, and we have no plan to. What we may eventually do is share aggregate, anonymous caffeine trends — things like "cold brew was up 12% in Seattle last week."
•We are not doing this yet. If and when we start, we will tell you in the app first and update this page.
•It would never include your account, your photos, your posts, your comments, your name, your email, your phone number, or your exact coordinates.
•Group numbers only get released when the group is large enough that no single person can be picked out of it. Inside the app today that means at least 5 people and 20 drinks in a week before a community stat appears at all, and anything we ever share would meet that bar or a higher one.
•Deleting a post or your account stops it counting toward anything worked out from then on. Figures already published can't be un-published.

•You can ask for a copy of everything we hold about you, ask us to correct it, or ask us to delete all of it. Email buzzincaffeine@gmail.com and we'll take care of it.
•You can delete any individual post yourself, at any time, from the post's delete button.
•You can delete your entire account yourself from your profile page — profile, posts, photos, comments, reactions and friendships all go with it, immediately.
•Depending on where you live you may have additional rights — for example under the CCPA in California or the GDPR in the UK and EU. Write to us and we'll honour them regardless of where you are.
•We won't treat you differently for exercising any of this.

•BUZZIN is for people aged 13 and up, and we ask for a birth year at signup to check.
•We don't knowingly collect anything from under-13s. If you believe a child has an account, email us and we'll remove it.

•Access to your data is enforced in the database itself with row-level security, so a bug in the app can't hand your friends-only posts to a stranger.
•No service is perfectly secure, and we can't promise otherwise — but we don't store anything we don't need.
•If we change this policy in a way that matters, we'll tell you in the app rather than quietly editing this page.
