Poster

Privacy policy

Effective August 18, 2026 · Applies to the Poster iOS app and poster.fyi

Poster is built around one idea: you photograph event posters in the real world, and they become events other people nearby can find. That means some of what you capture is meant to be public — this page spells out exactly what is, what isn't, and what we do with your photo.

What happens when you capture a poster

When you photograph a poster, we read and extract ("scrape") information from your photo — the event's title, date and time, venue, address, price, and category. This extraction happens on your phone, not on our servers. When you tap Publish, two things are uploaded:

• the processed photo of the poster, and
• the event details extracted from it (as edited by you before publishing).

Both become public: the photo and event details are visible to anyone using Poster, alongside your display name. Don't capture things you don't want published — poster photos should be of posters, not people. If a photo captures something it shouldn't, email us and we'll take it down, and any user can report an event in the app (events reported by several people are hidden automatically).

What we collect

• Account: a random account ID created silently when you first interact. A display name if you publish. Your phone number only if you verify it (required after your fourth published event).
• Content: poster photos you publish and the event details extracted from them.
• Location: your approximate location is used to show nearby events. Where you captured a poster is uploaded with the capture to help match duplicate posters and place the event.
• Activity: RSVPs, follows, groups you create, capture streaks, points and badges, reports you file, users you block, and feedback you send.

What's public

Poster is a public, browse-without-an-account app. Visible to anyone: published poster photos and their event details, your display name, your capture history and badges (your "Posterdex"), RSVP counts, and the leaderboard. Not public: your phone number, your precise capture locations (only the event's location is shown), your saved-events list, who you follow, your groups, and who you've blocked or reported.

What stays on your phone

The reading of posters — text recognition and event extraction — runs on your device. Calendar sync happens through Apple's EventKit on your phone; we never see your calendar. Photos you don't publish never leave your phone.

What we don't do

No ads. No trackers or third-party analytics, in the app or on this site. We don't sell your data, and we don't use your photos or data to train AI models.

Who processes data for us

Our backend (database, photo storage, and phone verification) runs on Supabase. Verification codes are delivered by an SMS provider, which necessarily handles your phone number in transit. That's the whole list.

Deleting your stuff

Email hello@poster.fyi from any address and tell us your display name or phone number — we'll delete your account and everything tied to it, or individual captures if that's all you want. During the beta this is handled by a human (quickly).

Changes

If this policy changes in a way that matters, we'll say so in the app before the change applies. This page always has the current version.
