Service providers

Last updated: August 2026

Like most apps, Hangpost relies on a few trusted companies to run behind the scenes: to host the app, store your photos, keep you signed in, and keep things safe. Each one only handles the data it needs to do its job, and only to run Hangpost for us. None of them use your data for their own advertising.

Here's the kind of help we use, and what it touches:

• Hosting and infrastructure: runs the app and stores your account, profile, posts, and connections.
• Sign-in and accounts: verifies your phone and email and keeps you logged in.
• Photo storage: holds the photos you choose to upload.
• Safety and content checks: automated review of uploaded images for explicit content, plus a check that compares uploaded images against databases of known child sexual abuse material. That child-safety check is run by a nonprofit in Canada; everything else runs in the United States.
• Identity verification (optional): if you choose to verify your identity, a specialist provider checks your government-issued ID and matches it to a selfie, on its own systems. We receive only the result and the time, never the ID and never the selfie.
• Email: sends account and service messages, like your waitlist confirmation.
• Error and performance monitoring: helps us find and fix bugs and crashes. Personal details are stripped out before anything is sent.
• Ad measurement: when we buy an ad (like a Google search ad, or a Meta ad on Facebook or Instagram), a measurement tag from that ad network (Google, or Meta Platforms, Inc. in the United States) on our public website counts whether that ad led to a waitlist signup, so we know which ads work. Google's personalization signals are off, Meta's tag runs with Limited Data Use enabled and no advanced matching, and neither tag ever receives your name, email, or phone.
• Match-quality evaluation: an AI provider used only in an offline process to score how good our match suggestions are. It works from profile-derived text, never your messages or your contacts.
• App delivery and notifications: the app stores and push services that get Hangpost onto your phone.

What we don't use: no ad-targeting, no retargeting, and no cross-app tracking. We don't sell your data, and there are no third-party advertisers on Hangpost: nobody buys ads inside the product, and the ad-measurement tags above only count our own ads' signups on the public website.

Want the specific companies behind any of these? Email privacy@hangpost.app and we'll share the current list. We update it before any new provider starts handling your data.
