Your worlds: they never mix

Your surf mates will never see your other private albums.

Public by default:
just 9 photos.
10 messages exchanged:
the Connection becomes a Friend.
No chats, the bond fades…
just like real life.
Private albums:
only the friends you add.

Why switch to Hi?

1. A sealed-off space

What happens on Hi stays on Hi

  • Leak-proof bunker: no bridges to the outside, screenshots blocked. Your content doesn't leave the app to end up on other networks.
  • You call the shots: you choose who sees what, and nothing gets saved behind your back, not by your contacts, not by the app.

2. A calm space

Rediscover the joy of chatting, no pressure

  • Real connections: no likes, no chasing followers. Only you can see how many friends you have.
  • Free to evolve: explore every side of you, speak your mind, change it. Your past doesn't follow you.

Our absolute ethical promise

Zero AI Zero Addictive Algo Zero Ads Zero Data Selling

A model 100% funded by its users to guarantee our independence.

Frequently asked questions

Does Hi really delete everything, even from servers?
  • Yes, completely. Your chats expire and are wiped for good, even from our servers.
  • Your personal hub: Your profile and albums stay. However, every photo or text saved in an album expires after 1 year.
  • What no longer exists cannot be stolen, sold, or exploited.

What happens if law enforcement requests my messages?
  • Reported content is frozen immediately for review. We fully comply with formal legal demands.
  • What we hold: Only your username, technical ID, and your confirmation that you're 13 or over. No name, no email, no phone number.
  • Authorities use your technical ID to request your real identity from Apple/Google. We only hand over that ID and the frozen content.

Why is Hi a paid service?
  • No ads. No data selling. Ever.
  • You are our user, not our product. Your subscription directly funds our servers and privacy architecture.

What is the difference between a “Connection” and a “Friend”?
  • Connection: Can message you, but cannot send photos, links, or view private albums. They can't recommend you, and you can't recommend them to your friends or in a circle. Zero pressure, zero traps.
  • Friend: By genuinely chatting, a Connection becomes a Friend and unlocks full sharing features.

Is my data secure?
  • Yes, encrypted in transit and at rest.
  • No end-to-end encryption: Why? To allow human moderation that actively protects young users against harassment and sextortion.
  • Conversations are only inspected when reported. And whatever is wiped after 48h is permanently deleted, even from our servers.

Why limit group sizes?
  • A real community isn't a feed of 50,000 strangers.
  • Group chats stay human-sized: even our largest Circles and Events cap at 250 people. Big enough to gather, small enough for real human moderation.

Why is Hi perfect for young users?
  • Anti-pressure design: Messages clear in 48h, no photos/links with basic Connections.
  • No popularity contest: No likes, no addictive algorithms. You can grow up without your past following you forever.
  • For ages 13 and up: You confirm your age when you sign up. If your phone is set up as a child account, the store blocks the download or asks your parents for permission.

Why protect privacy if I have nothing to hide?
  • Privacy isn't about secrets, it's about personal space. You close the bathroom door even when doing nothing wrong.
  • On other platforms, accumulated data is used to profile or target you. On Hi, data is erased, so it can't be used against you.

How does airtight privacy work day-to-day?
  • Your different spaces (One-on-Ones, Circles, Events) are completely isolated from each other.
  • Nothing leaks between groups, and no one can cross-reference your identity across spaces.

How do I invite my real friends if it's airtight?
  • You remain in full control: share your username or unique link directly with the trusted people you choose.
