Happ

Privacy Policy

Effective date: August 14, 2026

Happ (“Happ,” “we,” “us”) is a social app that turns discovery, coordination, and community into a single object: every item in your feed is an upcoming, plannable event. This policy explains what information we collect, why, how we handle it, and the choices you have.

We built Happ on a simple commitment: we never sell your personal information, and we never sell or expose data about an individual user. That is a permanent design rule, not a marketing line.

Who we are

Happ is operated by HAPP THE APP, LLC. If you have any question about this policy or your data, contact us at privacy@happtheapp.com.

Information we collect

We collect only what the app needs to work.

Account & sign-in. You sign in with Google or Apple. From your chosen provider we receive your name, email address, and (if available) profile photo. If you use Apple’s “Hide My Email,” we receive only the private relay address Apple provides. We do not see or store your Google or Apple password.

Your profile. Information you add to your profile — display name, handle, bio, photo, and (for a community you manage) details like meeting information, website, or phone number that you choose to publish.

Content you create. Events you create or manage, plans you make (adding an event, marking that you’re going), check-ins when you attend, comments you post on public events, communities you create or join, and any photos you attach (event covers, check-in photos, avatars, community banners).

Activity within the app. To make the feed useful and to understand how the core experience is performing, we record the actions you take in the app — for example adding or dismissing an event, following a person or community, opening an event, and the feed context an action came from. This is behavioral usage data about how the app is used. It is used to operate and improve Happ; it is not sold, and it is not used to build advertising profiles.

Your phone number — optional, and only if you turn it on. You can choose to add your phone number so that friends who already have your number in their contacts can find you on Happ (“let friends find you”). This is entirely optional — Happ never requires a phone number, and nothing else in the app depends on it. If you add one, we verify it by sending you a one-time code by SMS.

Your verified number is used for matching only, in two ways: friends who have you in their contacts can find you, and any invitation someone already sent to that number is delivered to your account. It is never shown on your profile, never visible to other users, and never used for marketing. An unverified number is never used for either. You can remove your number at any time in the app, which deletes it.

Contacts — checked, never kept. Allowing Happ to see your contacts is optional, and it only happens when you tap something that asks for it (finding friends, or inviting people to an event or community). Here is exactly what happens:

• Your address book stays on your device. Names, emails, addresses, notes and every other field never leave it.
• When you use find-friends, the app sends phone numbers from your contacts to be checked against the verified numbers of users who chose to be findable. When you pick specific people to invite, only those people’s numbers are sent.
• We compare, return the matches, and discard the numbers immediately. We do not store your contacts, we do not build a copy of your address book, and there is no browsable “your contacts on Happ” list. The only record kept is a count of how many numbers were checked, which we use to stop the feature being abused — never the numbers themselves.
• Contacts who are not on Happ produce nothing on our servers, with one exception you control: if you deliberately invite one of them (below).

People you invite who aren’t on Happ yet. If you pick someone from your contacts and invite them to an event or community, we store that pending invitation — which requires storing their phone number, because that is the only way the invitation can be waiting for them if they join. We treat that number carefully, because it belongs to someone who is not our user:

• It is used for one purpose only: matching that pending invitation to their account if they sign up and verify that number. It is never used for marketing, never sold, never shared, and never used to build any profile or “shadow” account. It cannot be searched or seen by anyone but you, the person who sent the invitation.
• It expires on its own: an event invitation is deleted when the event ends, and a community invitation is deleted after 180 days.
• You can delete it earlier, and either of us can: it disappears when you withdraw the invitation or when the event is cancelled or deleted.
• The text message comes from your phone, not from us. Happ opens your own Messages app with the words filled in; you decide whether to send it. Happ never sends text messages to people who aren’t users, and never sees the message you send.
• If you are that person and want your number removed before it expires, email privacy@happtheapp.com and we will delete it.

A note kept on your device only. When someone you invited from your contacts turns out to be on Happ, your device remembers the link between them so that a later “who hasn’t answered yet?” reminder can open a message to the right person. That note stays on your phone, is never uploaded to us, and goes away when you delete the app.

Feedback you send us. If you report a bug or send a suggestion (from the menu, or by shaking your phone), we collect your message, your app version, device platform, the screen you were on, and any screenshots you choose to attach. Screenshots are stored privately and are used only to understand and fix the problem.

Safety reports you make. If you report a person, an event, a comment or a message, or block someone, we record the report, who made it, what it points at, and any reason you gave, so we can act on it and keep a record of what was decided.

Technical data. Standard information needed to deliver and secure the service, such as your device type and app version, and network information (like IP address) handled by our infrastructure provider. If you enable push notifications, we store a push token for your device (an identifier that lets us send notifications to it) and a history of the notifications we sent you.

Location. Happ does not collect your device’s location, and nothing in the app requests it today. We never track you in the background — the app is built without that ability, not merely set not to use it. Events carry the place their host typed in, which is information about the event, not about you. If we later add a feature that needs your location (finding events near you, or confirming you’ve arrived at an event you’re attending), it will be optional, it will ask you first through your device’s normal permission prompt, and it will only ever read your location while you are using the app.

Your calendar. Happ does not read or change your calendar today. If you later choose to have Happ add events you’re going to into your calendar, it will ask your permission first, and it will only add or update the events you asked it to — it never reads your other appointments to learn about you.

How we use your information

• To provide the core experience: show you relevant upcoming events, let you plan and coordinate, and let communities organize.
• To operate features you use: sign-in, following, invitations, comments, check-ins, and (if you opt in) letting friends who have your number find you.
• To send you notifications you’d expect — invitations, changes to events you’re going to, reminders, and coordination updates. You can turn notifications off in your device settings at any time.
• To keep Happ safe and working: check photos and messages for prohibited content, act on reports and blocks, prevent abuse, debug problems, and secure accounts.
• To understand and improve how the core experience performs, in aggregate.

Automated content moderation. Before a comment or community message is posted, its text is automatically checked by a content-moderation service (provided by OpenAI). The service receives the text of the message only — not your name, account, or contact information — and is not permitted to use it for its own purposes. If a message is refused, we record that a refusal happened and the policy categories involved, but not the text of the refused message.

Photo safety checks, and our legal duty to report. Every photo uploaded to Happ — event covers, avatars, community banners, check-in photos — is automatically checked against a database of known child sexual abuse material before it is stored. The check works on a digital fingerprint of the image (a “hash”), not on the picture’s content or who is in it; the fingerprint is sent to Microsoft’s PhotoDNA service for comparison. Photos that do not match are stored normally, and no record of the check’s content is kept. If a photo matches, we are required by U.S. law to report it to the National Center for Missing & Exploited Children (NCMEC), together with the information the law requires, and to preserve the material for the authorities. We will also suspend the account involved. This is a legal obligation we cannot opt out of, and we would not want to.

How we share your information

We share information only in these limited ways:

With other users, as the app is designed to work. For example, a public event you create is visible to people who can see that event; your name and photo appear on events you host or attend; who’s going to an event may be shown to others who can see it. What is visible is governed by the event’s audience and by your relationships in the app.

With service providers who run Happ for us:

• Supabase — our database, authentication, file storage, and hosting provider. Your account, content, and images are stored on Supabase infrastructure.
• Google and Apple — only for the sign-in method you choose.
• Sentry — crash and error diagnostics, so we can find and fix bugs. If the app crashes or errors, Sentry receives technical data (device model, operating system, app version, and the error’s technical details). It does not receive your messages, events, or contacts.
• OpenAI — automated content moderation. Receives only the text of a comment or message being checked before it is posted; never your name, account, or contacts.
• Expo and Apple/Google — push-notification delivery. If you enable notifications, your device’s push token and the content of each notification pass through these services to reach your device.
• Twilio — SMS delivery, for one thing only: if you choose to add your own phone number, Twilio delivers the one-time verification code to it. Invitations to people who aren’t on Happ are sent by you, from your own phone, and never pass through Twilio or any other service of ours.
• Microsoft (PhotoDNA) — the photo safety check described above. Receives a digital fingerprint of an uploaded image, not the image itself and not your identity.
• NCMEC and law enforcement — only where a photo matches known child sexual abuse material, as U.S. law requires.
• Resend — email delivery for operational messages (for example, delivering your bug reports and feedback to us).

These providers process data on our behalf under their own security and privacy terms; they are not permitted to use it for their own purposes.

For legal reasons — if required by law, or to protect the rights, safety, and security of our users, the public, or Happ.

We do not sell your personal information, and we do not sell or expose data about an individual user — ever.

Where your data is stored and how it’s protected

Your data is stored on Supabase (which runs on cloud infrastructure). Data is encrypted in transit (HTTPS). Access to production data is limited to what is needed to operate the service. No method of storage or transmission is 100% secure, but we take reasonable steps to protect your information.

Happ is operated from the United States, and your information is stored and processed on infrastructure located in the United States. If you access Happ from outside the United States, you understand that your information will be transferred to, stored, and processed in the United States, where data-protection laws may differ from those in your country.

Your choices and rights

• Access and update: you can view and edit your profile and content in the app.
• Phone number: adding a number is optional, and you can remove it at any time in the app — removal deletes it.
• Notifications: you can turn push notifications off in your device settings.
• Contacts: allowing access to your contacts is optional and controlled by your device’s permission settings. Happ never uploads your address book, and turning the permission off in Settings stops all contact checking immediately.
• Invitations you sent to non-users: you can withdraw one at any time, which deletes the stored number; otherwise it expires on its own (see above).
• Unfollow / leave: you can stop following a person or community, which is a normal in-app action.
• Hide your account: you can hide your account in the app. A hidden account stops appearing to other people and can be un-hidden by you.
• Delete: you can delete content you created (events, comments, check-in photos), and you can delete your account in the app — Settings → your profile. Deleting removes your identity: your sign-in is destroyed and your name, photo, handle, bio and phone number are erased. Things you did that are part of other people’s history — a comment in a shared thread, the fact that an event happened — remain, but they are no longer connected to you or to any name. You can also email privacy@happtheapp.com and we will process the request for you.
• Depending on where you live, you may have additional rights (such as access, deletion, or portability). Contact us and we will honor applicable rights.

Children’s privacy

Happ is intended for users age 13 and older; we do not knowingly collect personal information from children under 13.

Changes to this policy

We may update this policy as Happ evolves. If we make a material change, we will update the effective date above and, where appropriate, notify you in the app.
